ABSTRACTCamellia oleifera Abel. is the dominant woody oil crop under significant development in China. Wild C. oleifera in Lu Mountain is a valuable genetic resource with strong freezing tolerance. With high-throughput sequencing, the genome of wild C. oleifera in Lu Mountain was analysed and 700.3 Gb clean reads were obtained. The genome of wild C. oleifera was estimated as allohexaploid, and its haplotype genome size was about 2.69 Gb-2.79 Gb, with repeat content of 63.01%-73.02% and heterozygosity of 6.30%-7.43%, belonging to a very complex genome. The genomic draft was assembled that contained a total of 6,952,303 scaffolds with N50 length of 1.23 kb, and the overall length was 2.39 Gb with GC content of 40.87%. In the genomic draft, 1,104,618 SSRs were identified; scaffold1096012 and scaffold1779458 were identified as key genes associated with freezing tolerance combined with the transcriptome data of field plus lab experiments. In this study, the genomic background of hexaploid wild C. oleifera in Lu Mountain was revealed. This lays the foundation for obtaining the high-quality chromosome-level reference genome of wild C. oleifera. The identification of SSRs and key genes associated with freezing tolerance may contribute to the efficient exploration and utilisation of this genetic resource.KEYWORDS: Camellia oleiferahigh-throughput sequencinggenome surveygenomic draftsimple sequence repeatfreezing tolerance AcknowledgementsThis research was funded by the National Natural Science Foundation of China (grant no. 32270238).Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe data that support the findings in this research are deposited in the short read archive (SRA) databank (https://www.ncbi.nlm.nih.gov/sra) with the accession number PRJNA984951.Author’s contributionXH and RJ designed the experiments.

ABSTRACTNewly developed asparagus farming involves planting seedlings in year one and harvesting all emerging spears without allowing the mother ferns to grow. However, changes in asparagus growth over time are unclear. Here, four-year cultivation trials were conducted under different climatic conditions to investigate temporal changes in growth. Plants were monitored weekly. The growing period was divided into three periods: spring and fall, both within optimum growing temperatures, and summer. Spring to the first half of summer revealed two to three peaks of increase in the number of effective stems. The number of effective stems decreased during high temperatures and decreased precipitation periods (summer), and recovered with an increase in precipitation. The number of effective stems displayed peaks during the second half of periods II and III. The increase in stem diameter mostly occurred during summer. Finally, the growing years that occurred with high temperatures and low precipitation in summer showed a significant positive correlation between the yield and maximum stem diameters in spring. The results of this study indicate that plant growth can be used to schedule pest control, irrigation, and fertiliser application for plants with limited resources.KEYWORDS: Asparagus officinalis L.Days after plantingmean air temperaturenumber of effective stemsprecipitationstem diameter AcknowledgementsWe would like to thank Editage (www.editage.com) for English language editing.Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe data that support the findings of this study are available from the corresponding author, Satoru Motoki, upon reasonable request.Supplementary MaterialSupplemental data for this article can be accessed online at https://doi.org/10.1080/14620316.2023.2268066
摘要新开发的芦笋种植方法包括在第一年种植幼苗,并在不让母蕨类生长的情况下收获所有新出现的矛。然而,芦笋生长随时间的变化尚不清楚。在这里,在不同的气候条件下进行了四年的栽培试验,以研究生长的时间变化。每周对植物进行监测。生长期分为适宜生长温度下的春季、秋季和夏季三个时期。春季至夏季上半期,有效茎数增加出现2 ~ 3个高峰。有效茎数在高温和降水减少期(夏季)减少,随降水增加而恢复。有效茎的数量在II期和III期后半段达到峰值。茎粗的增加主要发生在夏季。夏季高温少降水生长年份的产量与春季最大茎粗呈显著正相关。本研究结果表明,植物生长可用于资源有限的植物的害虫防治、灌溉和施肥计划。关键词:芦笋;种植后平均气温;有效茎数;降水;披露声明作者未报告潜在的利益冲突。数据可用性声明支持本研究结果的数据可根据合理要求从通讯作者Satoru Motoki处获得。补充材料本文的补充数据可在https://doi.org/10.1080/14620316.2023.2268066上在线获取

ABSTRACTAquaporins (AQPs) are small integral membrane proteins that facilitate the efficient transport of small solutes like water, metalloids, urea, and CO2 across the membrane. Plant aquaporins are known to be involved in vital physiological processes like seed germination, stomatal movement, cell elongation, and reproductive growth. In the present study, 36 AQPs were identified through genome-wide computational analysis performed in the rose genome. Subsequent phylogenetic analysis classified the AQPs into five subfamilies, including 10 Plasma membrane intrinsic proteins (PIPs), 8 Tonoplast intrinsic proteins (TIPs), 9 Nodulin intrinsic proteins (NIPs), 3 Small intrinsic proteins (SIPs), and 6 uncharacterised intrinsic proteins (XIPs). Based on the prediction of silicon solute specificity, one of the NIPs is predicted to be a silicon transporter. Structural analysis revealed the characteristic six trans-membrane domains and two-half alpha helix harbouring two conserved NPA motifs in the majority of the predicted AQPs. The protein tertiary structures predicted with homology-based modelling were used to study the pore lining remains and to predict the solute transport activity of the AQPs. Expression profiling of the rose AQPs showed tissue-specific expression of many members. The data provided here will help in understanding the AQP-based solute transport system in roses and other related species.KEYWORDS: AquaporinsRosaceaerosesolute specificitysilicon AcknowledgementsThe authors are thankful to the “Department of Biotechnology (DBT), Government of India (GoI)”, for the “Ramalingaswami Fellowship Award” to R.D. and H.S. and grants BT/PR32853/AGIII/103/1159/2019 and BT/PR38279/GET/119/351/2020 to H.S.; The Science and Engineering Research Board (SERB), India, Department of Science and Technology (DST), Government of India (GoI), for research grant CRG/2019/006599 awarded to R.D., and H.S., and for research grant SRG/2021/000077 to SN.

四孔蛋白(AQPs)是一种小的完整膜蛋白,促进小溶质如水、类金属、尿素和二氧化碳在膜上的有效运输。植物水通道蛋白参与了重要的生理过程,如种子萌发、气孔运动、细胞伸长和生殖生长。在本研究中,通过对玫瑰基因组进行全基因组计算分析,鉴定出36个AQPs。随后的系统发育分析将AQPs分为5个亚家族,包括10个质膜内在蛋白(PIPs), 8个Tonoplast内在蛋白(TIPs), 9个结节蛋白(NIPs), 3个小内在蛋白(SIPs)和6个未表征的内在蛋白(XIPs)。基于对硅溶质特异性的预测,预测其中一个NIPs是硅转运体。结构分析显示,在大多数预测的aqp中,具有六个跨膜结构域和两个半α螺旋,其中包含两个保守的NPA基序。基于同源性模型预测的蛋白质三级结构被用于研究孔隙衬里残留物,并预测AQPs的溶质运输活性。玫瑰AQPs的表达谱显示了许多成员的组织特异性表达。本文提供的数据将有助于了解玫瑰和其他相关物种中基于aqp的溶质运输系统。作者感谢印度政府(GoI)生物技术部(DBT)授予rd和H.S.“Ramalingaswami奖学金”,并向H.S.授予BT/PR32853/AGIII/103/1159/2019和BT/PR38279/GET/119/351/2020;印度科学与工程研究委员会(塞尔维亚)、印度政府科学技术部(DST)授予研发部和hs的研究资助CRG/2019/006599,以及授予SN的研究资助SRG/2021/000077。PR感谢印度塞尔维亚政府提供项目协会一级奖学金。PK感谢icar花卉研究局主任提供的资金支持。披露声明作者未报告潜在的利益冲突。补充资料本文的补充资料可在https://doi.org/10.1080/14620316.2023.2272153Data网站上获得可用性声明作者确认,支持本研究结果的数据可在文章及其补充资料中获得。本研究得到了印度科技部生物技术司的支持[BT/PR32853/AGIII/103/1159/2019];科学与工程研究委员会[SRG/2021/000077]。

ABSTRACTPRRs (pseudo-response regulators) genes play crucial roles in plant growth and development, stress response and other life activities. However, this gene family in cabbage (Brassica oleracea var. capitata L) has yet to be comprehensively studied. To fully understand the status of PRR in cabbage, ten BoPRR genes were extracted from the whole genome of cabbage through bioinformatics analysis, and their gene structure, protein conservative motifs, cis acting elements and collinearity relationships were identified and analysed. Quantitative real-time PCR (qRT-PCR) was used to explore the expression patterns of BoPRR genes in cabbage leaves under various abiotic stresses. Based on phylogenetic analysis, the ten BoPRR genes were divided into three branches, located on four chromosomes. In addition, many photoresponsive elements exist in the promoter region, and specific response elements with low temperature, drought and abscisic acid (ABA). In terms of gene expression patterns, all ten BoPRR genes were found to be expressed in cabbage leaves and showed response to abiotic stress. This study represents the first comprehensive examination of the PRR family in cabbage, providing a theoretical basis for further research on abiotic stress and offering a new gene resource for breeding stress-resistant varieties.KEYWORDS: Abiotic stressBoPRR genescabbagegenome wide analysis AcknowledgementsSJH secured the funding for the project.

【摘要】伪反应调节因子(prrs)基因在植物生长发育、逆境反应等生命活动中发挥着重要作用。然而,这个基因家族在甘蓝(芸苔甘蓝变种。capitata L)中尚未得到全面的研究。为了全面了解白菜PRR的现状,通过生物信息学分析,从白菜全基因组中提取了10个BoPRR基因,并对其基因结构、蛋白保守基序、顺式作用元件及共线性关系进行了鉴定和分析。采用实时荧光定量PCR (qRT-PCR)技术研究了不同非生物胁迫下白菜叶片BoPRR基因的表达规律。基于系统发育分析,将10个BoPRR基因分为3个分支,分别位于4条染色体上。此外,在启动子区域存在许多光响应元件,以及对低温、干旱和脱落酸(ABA)的特异性响应元件。在基因表达模式方面,10个BoPRR基因均在白菜叶片中表达,并对非生物胁迫表现出响应。本研究首次对大白菜PRR家族进行了全面研究,为进一步研究非生物胁迫提供了理论依据,并为培育抗逆性品种提供了新的基因资源。关键词:非生物胁迫boprr基因白菜全基因组分析感谢ssjh获得项目资金。XYY和SJH构思并设计了实验。XYY和JYJ进行了实验。XYY写了这篇论文。SJH和MAR对稿件进行了修改。所有作者都阅读并认可了稿件。披露声明作者未报告潜在的利益冲突。数据可用性声明本研究产生或分析的所有数据均包含在本文发表的文章中,并可作为补充信息参考。补充资料本文的补充资料可通过https://doi.org/10.1080/14620316.2023.2263763Additional info在线获取。32272728, 32272728)。

ABSTRACTYuzu (Citrus junos Sieb. Ex Tanaka) is widely cultivated in Asia. However, a system for variety identification has not been developed yet. RNA-seq analysis was performed to identify variants among five yuzu samples including a seedless variety. However, only four variants were found, suggesting that the seedless trait might originate from bud mutations. To identify more variants, whole-genome resequencing was performed. A total of 140 reliable variants were screened. Based on these variants, 30 high-resolution melting (HRM) markers were developed. After genotyping 265 yuzu samples using the HRM markers, the yuzu samples were classified into 18 types. Three yuzu-like samples (B-37-1, B-UK2, and B-MD6-8) showing different fruit morphologies and off-type HRM peak patterns were assumed to originate from interspecific hybridisation. To identify the parent species of these yuzu-like samples, nucleotide sequences of a hypervariable chloroplast genomic region and a nuclear CitRWP gene responsible for nucellar embryony were obtained. Chloroplast genome sequence analysis indicated that the maternal parents of B-37-1 and B-MD6-8 were yuzu, whereas the B-UK2 sequence was identical to that of sweet orange. Moreover, the CitRWP sequences indicated that the male parents of B-37-1, B-UK2, and B-MD6-8 were mandarin, yuzu, and pummelo, respectively.KEYWORDS: YuzuCitrus junosvariety identificationmolecular markerhigh-resolution meltingnucellar embryony AcknowledgementsThe authors thank Ji-hwa Heo, Jeong-An Yoo, and Su-jeong Kim for their dedicated technical assistance.

柚子(Citrus junos Sieb.)在亚洲广泛种植。但是,目前还没有一个品种鉴定系统。采用RNA-seq分析方法鉴定了包括无籽品种在内的5个柚子样品的变异。然而,只发现了四个变体,这表明无籽性状可能源于芽突变。为了确定更多的变异,进行了全基因组重测序。总共筛选了140个可靠的变异。基于这些变体,开发了30个高分辨率熔化(HRM)标记。利用HRM标记对265份柚子样品进行基因分型,将其分为18种类型。3个鱼祖样样品(B-37-1、B-UK2和B-MD6-8)表现出不同的果实形态和异型HRM峰模式,被认为是源自种间杂交。为了鉴定这些鱼祖样样品的亲本种,我们获得了一个高变叶绿体基因组区域和一个负责珠心胚胎的核CitRWP基因的核苷酸序列。叶绿体基因组序列分析表明,B-37-1和B-MD6-8的母本为柚子,而B-UK2序列与甜橙相同。此外,CitRWP序列表明,B-37-1、B-UK2和B-MD6-8的父本分别为柑桔、柚子和柚。作者感谢Ji-hwa Heo, Jeong-An Yoo和Su-jeong Kim的技术支持。本研究由“农业科技发展合作研究计划”(项目编号:No. 8111111)资助。PJ016161),由韩国农村振兴厅资助,由韩国教育部和韩国国家研究基金会资助的BK21 FOUR基金。披露声明作者未报告潜在的利益冲突。数据可用性声明本研究获得的转录组和全基因组重测序数据可在NCBI SRA数据库中获取。补充资料本文的补充资料可在https://doi.org/10.1080/14620316.2023.2265360.Additional information网站上获取。

Fresh produce handling, particularly in final inspection and pack, is highly dependent on dextrous human labour. As part of a relatively low-profit margin industry, rising wage costs and labour shortages are impacting the viability of this sector and are a direct threat to global food security. Adoption of robotics is required to automate delicate handling tasks; this is a key goal for sustainable and profitable businesses that supply packed produce to consumers. This mini review considers the state of the art, as well as any developments required in robotic technology for the automation of inspection and packing of whole unprocessed fresh produce. There is a particular focus on robotic end effectors for the handling of fresh produce. We consider the role of soft robotics research in meeting hygiene and safety requirements, as well as the current limited range of end effectors for handling of highly varied and delicate produce types. Future directions are discussed based on the observation of available current technology available in research and the application to commercial practice.
新鲜农产品的处理,特别是在最终检验和包装过程中,高度依赖于灵巧的人力。作为利润率相对较低的行业的一部分,工资成本上升和劳动力短缺正在影响该行业的生存能力,并对全球粮食安全构成直接威胁。需要采用机器人技术来自动化精细的处理任务;这是为消费者提供包装产品的可持续和盈利企业的关键目标。这篇迷你评论考虑了最新的技术,以及机器人技术在整个未加工新鲜农产品的自动化检查和包装方面的任何发展。有一个特别关注的机器人末端执行器处理新鲜农产品。我们考虑软机器人研究在满足卫生和安全要求方面的作用,以及目前有限范围的末端执行器,用于处理高度多样化和精致的产品类型。基于对现有研究技术和商业实践应用的观察,讨论了未来的发展方向。

ABSTRACTPitaya fruit has highly edible, medicinal, and economic value. Currently, pitaya is often used as fresh fruit to meet the market demand of consumers. However, pitaya fruit is prone to mechanical damage, microbial infection, and softening and decay after harvest, affecting the quality and shelf life of fresh pitaya fruit. Therefore, many technologies have been developed to extend the postharvest storage time of fresh pitaya. This review summarises the internal and external factors that affect the deterioration in quality of pitaya fruit after harvest and introduces the types of preservation technologies for pitaya fruit presently available. This includes physical, chemical, and techniques based on natural substances to extend the shelf life of postharvest pitaya fruit, as well as the control methods of postharvest diseases and pests. Future research needs to consider the combined application of various technologies to improve the preservation of pitaya.KEYWORDS: PitayapostharvestTechnologypreservationqualityshelf life AcknowledgementsThis review is supported by Outstanding Young Scientist Program of Guizhou Province under grant number KY [2021]028; Regional Fund of the National Natural Science Foundation of China (32260799); Cultivation Research Program of Guizhou University under grant numbers [2019]42.Disclosure statementThe authors declare no conflict of interest.Data availability statementAll relevant data are within the paper.

ABSTRACTGuava (Psidium guajava L.), a member of the family Myrtaceae, is the third richest source of vitamin C after Barbados cherry and aonla. Guava has many medicinal properties associated with every plant part. Coloured guava has additional nutritive value due to its lycopene, anthocyanin, and carotenoid content, which impart colour to its pulp and serve as potential antioxidants. In this review, the various categories of pulp colour in guava, genetics of pulp colour, pigments responsible for various pulp colours, and the biosynthetic pathway of those pigments are presented in detail. The recent advances in guava show that both carotenoids and anthocyanins contribute significantly to its pulp colour. The final pulp colour of the guava depends on the relative proportion of the pigments, i.e. anthocyanins, lycopene, and other carotenoids.KEYWORDS: AnthocyaninsgeneticsGuavalycopenepsidium guajava Lpulp colour AcknowledgementsThis work is supported by ICAR-IARI, New Delhi, 110012, India.Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementData presented in all the figures and tables of the review paper are compiled from various sources.
摘要番石榴(Psidium guajava L.)是番石榴科的一员,是继巴巴多斯樱桃和乌拉之后第三丰富的维生素C来源。番石榴有许多药用特性与每一个植物部分有关。彩色番石榴具有额外的营养价值,因为它含有番茄红素、花青素和类胡萝卜素,这些物质赋予其果肉颜色,并作为潜在的抗氧化剂。本文详细介绍了番石榴果肉颜色的种类、果肉颜色的遗传、各种果肉颜色的色素以及这些色素的生物合成途径。番石榴的最新进展表明,类胡萝卜素和花青素对其果肉颜色有重要贡献。番石榴果肉的最终颜色取决于色素的相对比例,即花青素、番茄红素和其他类胡萝卜素。关键词:花青素;瓜石榴红;瓜爪哇;披露声明作者未报告潜在的利益冲突。数据可用性声明本综述中所有图表和表格中的数据均来自不同来源。

ABSTRACTCultivated pears are economically one of the most important fruits in temperate regions. Two separate taxonomic groups are distinguished, a European and Southwest Asian group, and an East Asian group. Pears have been cultivated at least since Ancient Greek times. Their taxonomy is often confusing, with 20 to 30 widely recognised species. Their outbreeding character and widespread hybridisation led to a huge number of different forms and crosses. The Caucasus is regarded as one of two main centres of diversity in the European and Southwest Asian group. In the Republic of Georgia, several wild species incl. Pyrus communis subsp. caucasica occur. Pyrus communis subsp. caucasica is the sister taxa of the European wild pear Pyrus communis subsp. pyraster, which can morphologically not be distinguished. The natural ranges of these two sister taxa do not overlap. Scientists assume two separate domestication events, in Europe and in Caucasus. In the Caucasus region, local pear cultivars remain genetically very close to wild pears which were used as rootstock, while the fruits are still used to produce a local schnapps. Today, wild pears are often endangered due to habitat loss and fragmentation. Wild pears constitute a rich genetic basis for future breeding.KEYWORDS: Pearscultivationplant breedingconservationCaucasuslandraces AcknowledgementsI would like to thank two anonymous reviewers for their comments which helped improve this review article. I would like to thank David Kikodze, Shalva Sikharulidze, and Zezva Asanidze (Ilia State University, Tbilisi, Georgia) for their valuable information on the distribution and use of wild pears in Georgia.

摘要栽培梨是温带地区最重要的经济水果之一。两个独立的分类群被区分开来,一个是欧洲和西南亚群,一个是东亚群。至少从古希腊时代起,人们就开始种植梨了。它们的分类常常令人困惑,只有20到30种被广泛认可的物种。它们的近亲繁殖特征和广泛的杂交导致了大量不同的形式和杂交。高加索地区被认为是欧洲和西南亚群体中两个主要的多样性中心之一。在格鲁吉亚共和国,几种野生种包括Pyrus communis subsp.。caucasica发生。梨属植物。高加索是欧洲野生梨(Pyrus communis)亚种的姐妹分类群。Pyraster,在形态上无法区分。这两个姊妹分类群的自然分布范围不重叠。科学家们假设在欧洲和高加索地区发生了两次不同的驯化事件。在高加索地区,当地的梨品种在遗传上与用作砧木的野生梨非常接近,而其果实仍然用于生产当地的杜松子酒。如今,由于栖息地的丧失和碎片化,野生梨经常濒临灭绝。野生梨为今后的育种提供了丰富的遗传基础。关键词:梨栽培;植物育种;保护;高加索地区;我要感谢David Kikodze、Shalva Sikharulidze和Zezva Asanidze(格鲁吉亚第比利斯伊利亚州立大学)就格鲁吉亚野生梨的分布和利用提供的宝贵信息。David Kikodze和Filippo Guzzon对这份手稿的早期版本进行了评论。stenjophane rivire制作了如图5和图6所示的地图。这项工作没有得到外部资助。披露声明作者未报告潜在的利益冲突。数据可用性声明作者确认没有其他数据可用。
