Steviol glycosides (SGs), the diterpenoids group of plant secondary metabolites, possess phytopharmaceutical properties. Steviol glycosides are principally obtained from the stevia (Stevia rebaudiana) plant, which belongs to the Asteraceae family. Nowadays SGs are mainly used in the food and beverage industries as a non-caloric natural sweetener, which is about 300 times sweeter than sucrose. Among the known SGs, stevioside, and rebaudioside-A are the most abundant in the stevia leaf. Recent studies have shown that agronomic and biotechnological factors principally govern the accumulation of SGs in stevia plants. Therefore, to meet the burgeoning demand for SGs, efforts have been made to modulate the biosynthesis of these bioactive compounds in stevia using different agronomic and biotechnological strategies. In this review, we lucidly discussed agronomic and biotechnological approaches that stimulate and enhance the biosynthesis of SGs in stevia. Detailed mechanistic information could support us in making a plan for the production of SGs through stevia cultivation. We also outline some promising areas for future research that would inspire studies aiming to understand the consequence of interaction effects among the environmental and agronomic factors for the biosynthesis of SGs.
甜菊醇苷(SGs)是植物次生代谢产物中的二萜类,具有植物药特性。甜菊醇苷主要取自菊科植物甜叶菊(Stevia rebaudiana)。目前,甜菊糖主要用于食品和饮料行业,是一种无热量的天然甜味剂,其甜度约为蔗糖的 300 倍。在已知的甜菊糖中,甜菊糖甙和甜叶菊甙-A 在甜菊叶中含量最高。最近的研究表明,甜叶菊植物中 SGs 的积累主要受农艺和生物技术因素的影响。因此,为了满足对甜叶菊 SGs 不断增长的需求,人们一直在努力采用不同的农艺和生物技术策略来调节甜叶菊中这些生物活性化合物的生物合成。在这篇综述中,我们清晰地讨论了刺激和加强甜叶菊中 SGs 生物合成的农艺和生物技术方法。详细的机理信息可帮助我们制定通过甜叶菊种植生产 SGs 的计划。我们还概述了一些有希望的未来研究领域,这些领域将激励旨在了解环境和农艺因素之间相互作用对 SGs 生物合成的影响的研究。

Radix Paeoniae Alba (RPA) was subjected to a quick quality evaluation procedure using near-infrared (NIR) spectroscopy and chemometrics. The orthogonal partial least squares discrimination analysis (OPLS-DA) method was applied to the spectrum analysis based on SIMCA software, and a qualitative discriminant model was constructed to differentiate between the origin of RPA. Additionally, the NIR spectroscopy quantitative analysis models of gallic acid, methyl gallate, oxypaeoniflorin, catechin, albiflorin, paeoniflorin, 1,2,3,4,6-O-pentagalloylglucose, and benzoylpaeoniflorin were established by partial least squares method, with the content of components determined by HPLC serving as the reference value. To select the optimal spectroscopy pretreatment technique, the correlation coefficient R, root mean square error of calibration, root mean square error of prediction, and performance index were employed as assessment indices. The variable importance projection map was created using the OPLS-DA method to maximize the detection spectral band. The optimal number of factors was then determined using cross-validation, using the anticipated residual error sum of squares and the root mean square error of cross-validation as indicators. Ultimately, a quantitative model of the NIR spectrum was established using partial least squares with the spectral area of 9997.17 ∼ 8612.53 cm−1. Standard normal variation, second derivative, and no smoothing were used as pretreatments for the spectrum. The correlation coefficients of the eight components were all over 0.99, according to the model. Rapid, stable, dependable, and free of chemical reagent usage are the characteristics of the qualitative and quantitative models created in this work, which can be applied to the quick assessment of RPA's quality.
利用近红外光谱和化学计量学对赤芍(RPA)进行了快速质量评价。基于 SIMCA 软件的光谱分析应用了正交偏最小二乘判别分析(OPLS-DA)方法,并构建了一个定性判别模型来区分 RPA 的产地。此外,还以高效液相色谱法测定的成分含量为参考值,采用偏最小二乘法建立了没食子酸、没食子酸甲酯、氧芍药苷、儿茶素、白花蛇舌草苷、芍药苷、1,2,3,4,6-O-五聚酰基葡萄糖和苯甲酰芍药苷的近红外光谱定量分析模型。为了选择最佳的光谱预处理技术,采用了相关系数 R、定标均方根误差、预测均方根误差和性能指数作为评估指标。使用 OPLS-DA 方法创建了变量重要性投影图,以最大化检测光谱带。然后,以预期残余误差平方和和交叉验证均方根误差为指标,通过交叉验证确定最佳因子数。最终,利用偏最小二乘法建立了近红外光谱的定量模型,光谱区域为 9997.17 ∼ 8612.53 cm-1。标准正态变化、二次导数和无平滑作为光谱的预处理。根据模型,八个分量的相关系数均超过 0.99。快速、稳定、可靠、无需使用化学试剂是本研究建立的定性和定量模型的特点,可用于快速评估 RPA 的质量。

High light intensity improves yield of specialized metabolites in medicinal cannabis (Cannabis sativa L.), resulting from both higher inflorescence mass and concentrations of metabolites 高光照强度可提高药用大麻(Cannabis sativa L.)中特殊代谢物的产量,因为花序质量和代谢物浓度都更高
IF 3.8 2区 农林科学 Q1 PLANT SCIENCES Pub Date : 2024-09-21 DOI: 10.1016/j.jarmap.2024.100583
Medicinal cannabis (Cannabis sativa L.) contains various plant specialized metabolites, such as cannabinoids and terpenoids. These metabolites are mainly accumulated in inflorescences and are the primary focus of cultivation. Medicinal cannabis is often cultivated in indoor farming with electrical light, which allows for light intensities to optimize quantity and quality of production. Although it is known that an increase in light intensity results in increased inflorescence yield in cannabis, its impact on specialized metabolites remains unclear. We aim to quantify the effects of light intensity on the yield of specialized metabolites, and to elucidate which plant traits explain these effects, using a yield component analysis. Hereto, we conducted an experiment in a climate-controlled chamber using broad-band white LEDs at three light intensities: 600, 800, and 1000 µmol m−2 s−1 photosynthetic photon flux density (PPFD), applied during the generative phase (8 weeks with a 12-h photoperiod) in cannabis cv. ‘Critical CBD’. Yield of specialized metabolites, including cannabinoids and terpenoids, strongly increased with increasing PPFD due to increases in both their concentrations and inflorescence yield. The inflorescence yield showed a proportional increase with PPFD, resulting in a constant light use efficiency. The higher inflorescence dry mass was mainly caused by an increase in total plant dry matter production, and to a lesser extent a larger fraction of dry mass partitioned to the inflorescences. Leaf photosynthesis was higher for plants grown at higher PPFD. This study shows that cannabis can use very high light intensity, resulting in high yield of specialized metabolites due to high inflorescence mass and metabolite concentrations.
药用大麻(Cannabis sativa L.)含有多种植物专有代谢物,如大麻素和萜类化合物。这些代谢物主要积聚在花序中,是种植的主要重点。药用大麻通常使用电灯进行室内种植,这样可以通过光照强度来优化产量和质量。虽然已知光照强度的增加会导致大麻花序产量的增加,但其对特殊代谢物的影响仍不清楚。我们的目的是量化光照强度对特殊代谢物产量的影响,并利用产量成分分析法阐明哪些植物性状可以解释这些影响。为此,我们在气候控制室中使用三种光强的宽波段白光 LED 进行了一项实验:600、800 和 1000 µmol m-2 s-1 光合光子通量密度 (PPFD),在大麻品种 "临界 CBD "的生长期(8 周,12 小时光周期)使用。随着 PPFD 的增加,大麻素和萜类化合物等专一代谢物的产量大幅增加,这是因为它们的浓度和花序产量都有所增加。花序产量随 PPFD 的增加而成正比增加,导致光利用效率保持不变。花序干重增加的主要原因是植物总干重的增加,其次是花序干重的增加。PPFD 较高的植物叶片光合作用较高。这项研究表明,大麻可以利用极高的光照强度,由于花序质量大、代谢物浓度高,因此专门代谢物的产量也高。

Dendrobium moniliforme (L.) Sw. is a rare and endangered epiphyte plant of Orchidaceae with significant medicinal and ornamental value in China. It is necessary to use artificial cultivation to protect the wild resources because of its difficulty to survive in the wild. To date, more and more researchers have paid attention to the importance of phenology in stem development, flowering, pollination and fruiting of Dendrobium, but no specific and detailed phenological scale was set. Based on the extended BBCH scale, we used morphological and anatomical techniques to observe and record the growth and development characteristics of D. moniliforme. As a perennial herb, the growth process was divided into juvenile period and adult period. The juvenile period can be divided into two phases: seed germination (0) and seedling morphogenesis. Four stages are composed of the seedling morphogenesis, i.e. leaf development (1), formation of side shoots (2), stem (protocorm) elongation (3) and adventitious root formation (4). The adult period can be divided into vegetative growth and reproductive growth phases. Vegetative growth phases include bud development (0), leaf development (1), shoot development (3), root development (4) and dormancy (9). The reproductive growth phases include inflorescence emergence (5), flowering (6), development of fruit (7) and ripening of fruit and seed (8). For the entire growth and development process of D. moniliforme, 74 secondary growth stages were further coded and described. Additionally, the time series of different development stages in the annual growth cycle were discussed. This extended BBCH scale may provide guidance for the production and management practices of D. moniliforme.
铁皮石斛(Dendrobium moniliforme (L.) Sw.)是我国珍稀濒危的兰科附生植物,具有重要的药用和观赏价值。由于其难以在野外生存,因此有必要采用人工栽培的方式来保护野生资源。迄今为止,越来越多的研究者开始关注物候在铁皮石斛茎干发育、开花、授粉和结果中的重要性,但还没有制定具体详细的物候尺度。基于扩展的BBCH量表,我们利用形态学和解剖学技术观察和记录了铁皮石斛的生长发育特征。作为一种多年生草本植物,其生长过程分为幼苗期和成株期。幼苗期可分为种子萌发(0)和幼苗形态发生两个阶段。幼苗形态发生分为四个阶段,即叶片发育(1)、侧芽形成(2)、茎(原茎)伸长(3)和不定根形成(4)。成株期可分为无性生长期和生殖生长期。无性生长阶段包括芽的发育(0)、叶的发育(1)、嫩枝的发育(3)、根的发育(4)和休眠(9)。生殖生长阶段包括花序萌发(5)、开花(6)、果实发育(7)以及果实和种子成熟(8)。在 D. moniliforme 的整个生长发育过程中,有 74 个次生生长阶段被进一步编码和描述。此外,还讨论了年生长周期中不同生长阶段的时间序列。这一扩展的 BBCH 量表可为 D. moniliforme 的生产和管理实践提供指导。

Clary sage is an important aromatic herb that has a high potential for commercial cultivation under the diversified climates of the Western Himalayas. The present study was carried out to understand the performance of genotypes and their interaction with the varied environments prevalent in the Western Himalayas and to identify stable and best-performing genotypes. In the present experiment, ten superior selections were evaluated in four different environments as multi-location trials in a randomized block design with three replications during 2021 and 2022. The pooled analysis of variance revealed significant variations for genotypes, environments, and genotype × environment interaction for all the studied traits. The highest mean performance suggests that Env-1 has the most suitable conditions for clary sage cultivation. The genotypes CSIR-IHBT-SS-07 and CSIR-IHBT-SS-09 were found to be the best performers for fresh inflorescence weight (418.73 g/plant) and essential oil content (428.91 mg/Kg), respectively. The results of Eberhart and Russell’s regression-based model confirm that the genotype CSIR-IHBT-SS-07 is a stable and superior genotype for the economically important traits. Further, the gas-chromatography mass spectroscopic characterization of essential oil disclosed that CSIR-IHBT-SS-07 was unique in terms of the highest sclareol content (23.39–45.17 %) across all the test environments. Genotype + Genotype × Environment biplot analysis confirmed that all the test environments form a single mega-environment. The study is a pioneer in unraveling the stability response of clary sage in Western Himalaya and provides a strong base for the identification of superior genotypes and selection strategy for future genetic improvement programs of clary sage.

Pre-emergence herbicide selection for successful cultivation of black seed (Nigella sativa L.), psyllium (Plantago ovata Forsk), and quinoa (Chenopodium quinoa Willd.) 为成功种植黑籽(Nigella sativa L.)、车前子(Plantago ovata Forsk)和藜麦(Chenopodium quinoa Willd.)

Weed control in black seed, psyllium, and quinoa is of huge importance for successfully cultivating and adapting these medicinal and nutritious crops. The recent study was designed to evaluate the pre-emergence herbicides (S-metolachlor and pendimethalin) for their possible application in these crops. The study consisted of three experiments on each crop for two years (2020–21, 2021–22). In each experiment, herbicides and their incremental doses (0 %, 25 %, 50 %, 75 %, and 100 % of recommended label dose) were applied under a randomized complete block design under the factorial arrangement. Data on weed dynamics, crop agronomic, and yield attributes were collected. Results revealed that the weed control efficiency of both herbicides ranged from ∼60–80 %. Crops, on the other hand, varied in their tolerance to both herbicides. Pendimethalin proved to be more detrimental for all the crops. Dose-response curves showed the crop tolerance to pendimethalin and can be ranked as black seed>psyllium and quinoa. Contrastingly, all the crops showed tolerance to the incremental dose of S-metolachlor.

黑籽、车前子和藜麦的杂草控制对于成功种植和适应这些药用和营养作物至关重要。近期的研究旨在评估萌芽前除草剂(S-甲草胺和戊唑醇)在这些作物上的应用可能性。这项研究包括对每种作物进行三次实验,为期两年(2020-21 年和 2021-22 年)。在每项实验中,除草剂及其递增剂量(推荐标签剂量的 0%、25%、50%、75% 和 100%)均采用因子排列的随机完全区组设计。收集了有关杂草动态、作物农艺和产量属性的数据。结果表明,两种除草剂的除草效率在 60%-80% 之间。另一方面,作物对两种除草剂的耐受性各不相同。事实证明,嘧草环胺对所有作物的危害都较大。剂量-反应曲线显示,作物对戊唑醇的耐受性可分为黑籽>车前子和藜麦。相反,所有作物都对甲草胺的递增剂量表现出耐受性。根据各自的 Ed50 值,对 S-甲草胺耐受的作物可分为黑籽>藜>车前草。研究得出结论,应避免在这些作物中使用戊唑醇。不过,S-甲草胺可作为一种萌芽前除草剂,以推荐的标签剂量用于黑籽、车前草和藜麦的种植。

Oregano species are commonly utilized for different medical purposes as well as for other essential oil products. One of the oregano species, Origanum onites L. has a dense natural distribution in the Aegean and Mediterranean regions of Turkey and Greece and is cultivated mainly in Denizli province. Turkey meets 80 % of the world's oregano market. Since Origanum onites L., whose essential oils are of high quality, has a high economic value, assessing the quality and production of essential oils extracted using various methods is important. Microwave-assisted distillation (MWAD) processes are generally carried out under laboratory conditions using clevenger or small-scale specialized instruments made for research in the lab. Thus, designing industrial-scale distillation systems with microwave power is necessary. For this reason, an industrial-type MWAD system with 12 magnetrons (power output of 1 kW) was developed in this work, and both conventional steam distillation (SD) and MWAD of oregano plant were realized, as a novelty. This study experimentally investigated the effects of microwave power and applied time on both energy saving (%) and essential oil yield (%). System was designed to distill 9 kg of dried plants chopped at once and the results obtained were used to obtain reference data for MWAD systems that can be used in industrial systems. The obtained essential oil samples were subjected to GC-MS analysis for chemical analysis. A statistical analysis of the experimental data was performed via Design Expert software to elucidate the impact of microwave power and time on essential oil yield and energy savings. When the results were evaluated, the essential oil yield of oregano plant increased by 4–22 % with the MWAD system compared to SD. The highest increase in yield was achieved with the test (500 W + 40 min). Also, the distillation time with MWAD system was 50 % shorter than with SD system. The MWAD system consumed at least 25 % less energy. According to the GC-MS analysis results, carvacrol increased steadily depending on the time applied microwave power as well as oxygenated monoterpenes. The chemical composition of the essential oils obtained from the proposed MWAD system did not show any incompatible value according to the ISO-7925 standard. As a result, this proposed method can be safely used in industrial systems.

牛至品种通常被用于不同的医疗用途以及其他精油产品。牛至品种之一 Origanum onites L. 密布于土耳其和希腊的爱琴海和地中海地区,主要在代尼兹利省种植。土耳其的牛至产量占世界牛至市场的 80%。由于牛至的精油质量上乘,具有很高的经济价值,因此对使用各种方法提取的精油的质量和产量进行评估非常重要。微波辅助蒸馏(MWAD)工艺通常是在实验室条件下,使用为实验室研究而制造的劈裂器或小型专用仪器进行的。因此,有必要设计具有微波功率的工业规模蒸馏系统。为此,本研究开发了一个带有 12 个磁控管(输出功率为 1 kW)的工业型 MWAD 系统,并实现了牛至植物的传统蒸汽蒸馏(SD)和 MWAD,这是一项创新。这项研究通过实验研究了微波功率和应用时间对节能(%)和精油产量(%)的影响。设计的系统可一次性蒸馏 9 公斤切碎的干植物,所获得的结果用于获得可用于工业系统的微波干馏系统的参考数据。获得的精油样品经过气相色谱-质谱分析进行化学分析。通过 Design Expert 软件对实验数据进行了统计分析,以阐明微波功率和时间对精油产量和节能的影响。评估结果表明,与 SD 相比,使用 MWAD 系统的牛至植物精油产量提高了 4-22%。测试(500 W + 40 分钟)中产量增加最多。此外,MWAD 系统的蒸馏时间比 SD 系统缩短了 50%。MWAD 系统消耗的能量至少减少了 25%。根据气相色谱-质谱分析结果,香芹酚以及含氧单萜的含量随微波功率的应用时间而稳步增加。根据 ISO-7925 标准,从拟议的 MWAD 系统中获得的精油化学成分没有显示任何不符合标准的值。因此,这种拟议的方法可以在工业系统中安全使用。

<div><p>Medicinal and aromatic plants (MAPs) from natural habitat have been integral to both traditional and modern medicine systems for their healing properties in curing various diseases and disorders of mankind. At the same time, cultivation of these crops has also become alternative source of income for farmers by providing raw materials to pharmaceuticals. Like other crops, MAPs also have to face various abiotic and biotic stresses leading to compromised yield and quality. Biotic stresses, encompassing diseases, nematodes, pests and parasitic flowering plants can directly or indirectly impact MAPs by altering their fundamental physiological processes leading to symptoms like leaf necrosis, chlorosis, tissue rotting, leaf spot, wilting, foliage defoliation, root damage, <em>etc</em>. In this review article, plausible explanations regarding physiology of stressed plants and its defense mechanisms including primary and secondary metabolism are presented. The research on source-stressor interactions in food crops is well-established as well as compiled and reviewed but there is a lack of comprehensive compilation in the context of MAPs. Therefore, this review is vital for exploring the mechanisms and physiological alterations in MAPs under biotic stress conditions. Plants, under attack of stressors respond with hypersensitive reactions (HRs), modifying cell wall properties, such as altered cell walls, chloroplast damage, changed chlorophyll content, altered stomatal behaviour causing change in gaseous exchange capacities, reformed enzyme activity and gene expression, leading to reduced photosynthesis and increased respiration. Along with this, nutrient assimilation and its translocation are adversely affected leading to compromised biomass production of the host plant. Additionally, the disruption in the balanced distribution of photosynthates between source-sink tissues leads to increased sugar utilization for defense, making the primary metabolism more complex in plant’s responses to these stressors. The compromised carbon fixation through primary metabolism diverts light energy towards secondary metabolism and results in increased secondary metabolites (SMs) production. SMs also get elevated as a part of host defense mechanism under mild stress conditions without significantly impacting the plant growth. However, in severe stress conditions, these improvement in quality cannot compensate the deviation in biological yield. Notably, in case of MAPs, the simulated application of biotic elicitors can also amplify SMs production, ultimately enhancing the plant's inherent qualities. Therefore, the secondary metabolism is of utmost importance in MAPs. In this review, we have compiled the scattered information and simplified the understanding of alterations in various physiological processes including primary and secondary metabolism, changes in biochemical attributes and gene expression profiles in MAPs during biotic stress situations.

来自自然栖息地的药用和芳香植物(MAPs)因其治疗人类各种疾病的疗效,已成为传统和现代医学体系中不可或缺的一部分。与此同时,这些作物的种植也通过提供制药原料成为农民的另一种收入来源。与其他作物一样,MAPs 也要面对各种非生物和生物胁迫,导致产量和质量下降。生物胁迫包括疾病、线虫、害虫和寄生花卉植物,可直接或间接影响 MAPs,改变其基本生理过程,导致叶片坏死、萎蔫、组织腐烂、叶斑病、枯萎、叶片落叶、根部损伤等症状。在这篇综述文章中,介绍了有关受胁迫植物的生理及其防御机制(包括初级和次级代谢)的合理解释。关于粮食作物中源-胁迫相互作用的研究已经非常成熟,并进行了汇编和综述,但在 MAPs 方面却缺乏全面的汇编。因此,这篇综述对于探索生物胁迫条件下 MAPs 的机制和生理变化至关重要。植物在受到胁迫时会出现超敏反应(HRs),改变细胞壁特性,如细胞壁改变、叶绿体损伤、叶绿素含量改变、气孔行为改变导致气体交换能力改变、酶活性和基因表达改变,从而导致光合作用减少、呼吸作用增加。与此同时,营养物质的同化和转运也会受到不利影响,导致寄主植物的生物量减少。此外,光合产物在源-汇组织间的平衡分布被破坏,导致糖的防御利用增加,使初级代谢在植物应对这些胁迫时变得更加复杂。通过初级代谢进行的碳固定受到影响,光能转向次级代谢,导致次级代谢产物(SMs)产生增加。在轻度胁迫条件下,次生代谢物作为宿主防御机制的一部分也会升高,不会对植物生长产生重大影响。然而,在严重胁迫条件下,质量的提高并不能弥补生物产量的偏差。值得注意的是,就 MAPs 而言,模拟施用生物诱导剂也能扩大 SMs 的产生,最终提高植物的内在品质。因此,次生代谢在 MAPs 中至关重要。在这篇综述中,我们汇编了零散的信息,并简化了对生物胁迫情况下 MAPs 各种生理过程(包括初级和次级代谢)变化、生化属性变化和基因表达谱变化的理解。对本综述中讨论的 MAP 生理变化进行广泛分类,将有助于规划针对受各种生物胁迫影响的 MAP 的抗性植物育种计划的研究战略。

Influence of seed pre-treatment and storage on germination and physiological characteristics of seeds of common mullein (Verbascum thapsus L.) 种子预处理和储藏对毛蕊花种子萌发和生理特性的影响
IF 3.8 2区 农林科学 Q1 PLANT SCIENCES Pub Date : 2024-08-30 DOI: 10.1016/j.jarmap.2024.100573

We report the seed germination and associated metabolic responses of differentially stored seeds of Verbascum thapsus L. (Scrophulariaceae), an economically and medicinally important herb from the cold desert region of Lahaul (Himachal Pradesh, India) in trans Himalaya, to certain physico-chemical and GA₃ treatments. The freshly harvested seeds of V. thapsus exhibited high (96 %) viability but low germination (55 %). During the storage of seeds under ambient conditions, viability did not change until 1-year but declined progressively thereafter showing a 33 % decline in 4-year stored seeds. The seed germination was promoted to varying extents by acid scarification (AS), SNP (sodium nitroprusside), SHC (sodium hypochlorite) and GA₃ pre-treatments. Storage-dependent changes in seed germination performance and responsiveness to different effectors were evident. Germination performance improved significantly due to 1-year storage followed by a sharp decline subsequently. The responsiveness of seeds to various treatments tended to be higher in seeds stored for ≥2 years. The changes in germination were paralleled by those in α-amylase activity in seeds. Lipid peroxidation generally increased during storage that was paralleled by a gradual decline in superoxide dismutase (SOD) activity and phenolic contents. Catalase (CAT) activity increased transiently in 1-year stored seeds and declined thereafter. Data are expected to have implications for multiplication and cultivation of V. thapsus.

我们报告了喜马拉雅山脉拉豪尔(印度喜马偕尔邦)寒冷沙漠地区的一种具有重要经济和药用价值的草本植物--Verbascum thapsus L.(毛莨科)的不同储藏方式的种子在某些物理化学和 GA₃处理下的萌发及相关代谢反应。刚收获的毛地黄种子显示出很高的存活率(96%),但发芽率较低(55%)。种子在环境条件下贮藏期间,存活率在 1 年前没有变化,但此后逐渐下降,贮藏 4 年的种子存活率下降了 33%。酸洗(AS)、SNP(硝普钠)、SHC(次氯酸钠)和 GA₃预处理在不同程度上促进了种子的萌发。种子的萌发性能和对不同效应因子的反应随储藏而发生明显变化。种子贮藏 1 年后,萌发性能明显提高,但随后急剧下降。贮藏≥2 年的种子对各种处理的反应性往往更高。种子α-淀粉酶活性的变化与发芽率的变化同步。在贮藏过程中,脂质过氧化通常会增加,同时超氧化物歧化酶(SOD)活性和酚含量也会逐渐下降。过氧化氢酶(CAT)活性在贮藏 1 年的种子中短暂上升,随后下降。预计这些数据将对毛蕊花的繁殖和栽培产生影响。

Genome-wide identification of SSR markers for Curcuma alismatifolia Gagnep., and their potential for wider application in this genus 莪术 SSR 标记的全基因组鉴定及其在该属植物中的广泛应用潜力
IF 3.8 2区 农林科学 Q1 PLANT SCIENCES Pub Date : 2024-08-10 DOI: 10.1016/j.jarmap.2024.100572

The genus Curcuma, containing over 120 species, have considerable ornamental, edible and medicinal value. Due to the persistent lack of efficient genomic SSR markers, the conservation and identification of Curcuma genetic resources have faced substantial challenges in practical applications. To date, there are few systematic researches on whole-genome mining of SSR locus in the genus Curcuma. Herein, we performed the first deep identification of genome-wide SSR markers based on the whole-genome data of C. alismatifolia. A total of 257,032 SSR loci were identified with an average density of 216.1–367.3 SSRs/Mb within each chromosome. Mononucleotide repeat loci were most abundant, accounting for 55.1 % of all SSRs, with dinucleotide and trinucleotide repeats accounting for 22.6 % and 20.3 %, respectively. Moreover, 38 polymorphic genomic SSRs (g-SSR) were screened from the synthesized 280 primer pairs, with an average allele number (Na) and polymorphic information content (PIC) of 15.342 and 0.775 per locus, respectively. These markers had excellent cross-species transferability with an overall efficiency of 97.5 % in 21 Curcuma species. According to the cluster and structure analyses, the 178 Curcuma accessions were devided into three major clades correspongding to their origins, hybrid affinities and use values. Finally, a total of 66 Curcuma core collections were preserved, with no significant difference in genetic diversity between the core and entire collections by the t-test. A combination of numbers and letters was employed to establish DNA barcodes for 66 core collections. This study provides valuable molecular markers for wild-collection and conservation, genetic diversity analysis and marker-assisted selection breeding of Curcuma.

莪术属包含 120 多个物种,具有相当高的观赏、食用和药用价值。由于长期缺乏高效的基因组 SSR 标记,莪术遗传资源的保护和鉴定在实际应用中面临巨大挑战。迄今为止,关于莪术属 SSR 位点全基因组挖掘的系统研究还很少。在此,我们首次基于 C. alismatifolia 的全基因组数据对全基因组 SSR 标记进行了深度鉴定。共鉴定出 257,032 个 SSR 位点,每个染色体内 SSR 的平均密度为 216.1-367.3 SSRs/Mb。单核苷酸重复位点最多,占所有 SSR 的 55.1%,二核苷酸和三核苷酸重复位点分别占 22.6% 和 20.3%。此外,从合成的 280 对引物中筛选出 38 个多态基因组 SSR(g-SSR),每个位点的平均等位基因数(Na)和多态信息含量(PIC)分别为 15.342 和 0.775。这些标记具有良好的跨物种转移性,在 21 个莪术物种中的总体效率为 97.5%。根据聚类和结构分析,178 个莪术品种被划分为三个主要支系,分别对应于它们的起源、杂交亲缘关系和使用价值。最后,共保留了 66 个莪术核心品系,经 t 检验,核心品系与整个品系的遗传多样性无显著差异。通过数字和字母的组合,为 66 个核心藏品建立了 DNA 条形码。这项研究为莪术的野生采集与保护、遗传多样性分析和标记辅助选育提供了宝贵的分子标记。
