Leaf epidermal micromorphology was investigated in selected Iranian representatives of the Cachrys clade (Apiaceae) using a comparative approach based on light microscopy (LM) and scanning electron microscopy (SEM). A total of multiple taxa representing different genera were examined to assess the taxonomic relevance of stomatal characteristics, trichome morphology, and cuticular ornamentation. Clear intergeneric differences were observed in qualitative characters such as trichome architecture, epidermal cell shape, and cuticular sculpturing, whereas most quantitative stomatal traits, including stomatal density and index, showed limited diagnostic value and appeared to be influenced by ecological or leaf-textural factors. Notably, Azilia eryngioides exhibited a distinctive combination of micromorphological features, including mixed anisocytic–anomocytic stomata, polygonal epidermal cells with flat periclinal walls, and wrinkled cuticular sculpturing, supporting its current generic circumscription. As the material examined was based on herbarium specimens, environmentally sensitive quantitative traits should be interpreted with caution. Overall, the results indicate that foliar micromorphological characters, particularly stable qualitative traits, provide useful complementary evidence for generic delimitation within the Cachrys clade, but are insufficient on their own to resolve intergeneric relationships, emphasizing the value of integrative taxonomic approaches combining morphological, molecular, and ecological data.
采用光学显微镜(LM)和扫描电镜(SEM)的比较方法,研究了猕猴桃科(Apiaceae)伊朗产猕猴桃枝(Cachrys)的叶表皮微形态。对代表不同属的多个分类群进行了研究,以评估气孔特征、毛状体形态和角质层纹饰的分类相关性。在毛状结构、表皮细胞形状和角质层雕刻等定性性状上,属间差异明显,而大多数定量气孔性状(包括气孔密度和气孔指数)的诊断价值有限,可能受生态或叶质因素的影响。值得注意的是,杜鹃花表现出独特的微形态特征组合,包括混合的各向异性-无型细胞气孔,多边形表皮细胞与平坦的周壁,褶皱的角质层雕刻,支持其目前的一般界限。由于所检测的材料是基于植物标本馆标本,因此应谨慎解释环境敏感的数量性状。总体而言,研究结果表明,叶面微形态特征,特别是稳定的质量性状,为猕猴猴枝属划分提供了有益的补充证据,但其本身不足以解决属间关系,强调了结合形态学、分子和生态数据的综合分类方法的价值。

The Himalayas are the most vulnerable regions to climate change, and they have been experiencing diverse impacts on mountain vegetation. Blue Pine (Pinus wallichiana) is an evergreen conifer which grows at altitudes of 1800–4300 m in dry valleys in Nepal Himalaya. We carried out a dendroecological study to examine growth-climate response of P. wallichiana on contrasting topography—relatively moist North facing and dry South facing slopes. Tree-ring width indices exhibited a significant positive correlation with the previous year’s September rainfall and negative correlation with the current year maximum temperature of June. The Basal Area Increment (BAI) generally showed a positive trend, however, both sites showed declining trends of BAI particularly after the 1980s, with a more pronounced decrease observed on the south-facing slope. This may be due to changes in topographic conditions due to slope exposure; higher evapotranspiration, strong wind and lower moisture supply due to low runoff from snow melting in the southern slope. However, we emphasize that responses from similar aged tree populations should be validated using more precise local climatic data to improve the interpretation of microclimate-driven growth-climate relationships and to strengthen climate adaptation strategies for Himalayan forests. Nonetheless, the results underscore the role of topographic variability in shaping forest sensitivity to climate, highlighting the importance of slope-specific considerations in forest management and adaptation strategies in Himalaya.
喜马拉雅地区是受气候变化影响最严重的地区,其山地植被受到了多种多样的影响。蓝松(Pinus wallichiana)是一种常绿针叶树,生长在尼泊尔喜马拉雅山脉海拔1800-4300米的干燥山谷中。在相对湿润的北坡和干燥的南坡上,我们进行了一项树木生态学研究,以研究白杨生长对气候的响应。树轮宽度指数与前一年9月降水量呈显著正相关,与当年6月最高气温呈显著负相关。基础面积增量总体呈上升趋势,但20世纪80年代以后,两个样地的基础面积增量均呈下降趋势,其中南坡下降更为明显。这可能是由于地形条件的变化,由于斜坡暴露;由于南坡融雪径流少,蒸散量大,风大,水分供应少。然而,我们强调,应该使用更精确的当地气候数据来验证类似古树种群的响应,以改进对小气候驱动的生长-气候关系的解释,并加强喜马拉雅森林的气候适应策略。尽管如此,研究结果强调了地形变异性在塑造森林对气候敏感性方面的作用,强调了在喜马拉雅地区森林管理和适应战略中考虑特定坡度的重要性。

South America is a region of high Asteraceae diversity. The subfamily Gochnatioideae (with its only tribe, Gochnatieae) represents an important evolutionary lineage that is considered key to understanding the evolution of Asteraceae in arid environments. The goal of our study is to analyze and compare the leaf morphology and anatomy of five Gochnatioideae species from southern South America: Cnicothamnus lorentzii, Cyclolepis genistoides, Gochnatia palosanto, Moquiniastrum polymorphum, and Pentaphorus glutinosus; distributed along a climatic gradient from arid to humid regions, with the objective of identifying and describing xeromorphic traits. Results revealed a great variability in leaf traits among the species. All species exhibited abundant glandular and non-glandular trichomes. Stomata were mostly raised, except in C. genistoides, which displayed semi-sunken stomata. Stomatal distribution was hypostomatic in C. lorentzii, G. palosanto, and M. polymorphum, and amphistomatic in C. genistoides and P. glutinosus. The mesophyll was either dorsiventral or isolateral. Cuticular thickening was observed in C. genistoides and M. polymorphum, while hypodermis was present only in M. polymorphum.
In conclusion, the observations indicate significant variation in leaf morphology and anatomy among the studied species. This study provides a preliminary descriptive framework that can serve as a comparative reference for future research on leaf diversity in Gochnatioideae in southern South America.
南美洲是菊科植物多样性较高的地区。Gochnatieae亚科(及其唯一的部落Gochnatieae)代表了一个重要的进化谱系,被认为是理解干旱环境下Asteraceae进化的关键。摘要本研究对南美南部五种gochatioideae物种:Cnicothamnus lorentzii、Cyclolepis genistoides、Gochnatia palosanto、Moquiniastrum polymorphum和Pentaphorus glutinosus的叶片形态和解剖结构进行了分析和比较;沿着从干旱到潮湿地区的气候梯度分布,目的是识别和描述旱胚特征。结果表明,不同种属间叶片性状差异较大。所有物种均表现出丰富的腺毛和非腺毛。气孔大部分是凸起的,除了金缕草为半凹陷的气孔。气孔分布以低气孔为主,而以双气孔为主。叶肉是背侧的或同侧的。龙胆草和多形草表皮增厚,而多形草只有皮下增厚。综上所述,观察结果表明,所研究物种的叶片形态和解剖结构存在显著差异。本研究提供了一个初步的描述框架,可为南美洲南部Gochnatioideae叶片多样性的进一步研究提供比较参考。

Phyllanthus sect. Phyllanthus comprising 17 morphologically homogeneous and taxonomically challenging species of notable medicinal relevance, represents a promising group for micromorphological investigations. In this study, we examine the leaf and stem anatomy of eight species from this section, with the aim of identifying diagnostic characters that support accurate species delimitation and/or reflect the environmental conditions of their habitats. Additionally, we performed a similarity analysis based on 59 macro- and micromorphological characters. Our results show that the studied species differ in stem characteristics (e.g., presence or absence of wings and trichomes, number of layers of the cortex, thickening or not of the pith cells) and leaf traits (e.g., contour of the epidermal cells in frontal view, stomatal arrangement and types, presence or absence of papillae, midrib contour, presence or absence of collenchyma, fibers and/or sclereids in the petiole and midrib, vascular bundles, number of cortical layers in the latter, proportion and distribution of palisade and spongy parenchyma, and the shape, composition, and orientation of the leaf margin). Other traits appear to be associated with environmental adaptations related to water limitation, light reflection and diffusion (e.g., cuticle and cell wall thickness, trichomes, papillae, hypostomatic leaves), mechanical support (e.g., fibers, sclereids), photosynthetic efficiency (e.g., amphistomatic leaves), energy storage (e.g., starch grains), and defense against herbivory and osmoregulation (e.g., trichomes, druses). The similarity analysis revealed two morphologically cohesive groups, which partially correspond to previous phylogenetic studies of the section. These findings expand the anatomical knowledge of the examined species and provide a foundation for future pharmacological, taxonomic, phylogenetic, and ecological research on Phyllanthus.
Phyllanthus节。Phyllanthus包括17个形态学上同质且分类上具有挑战性的物种,具有显著的医学相关性,是微形态学研究的一个有希望的群体。在这项研究中,我们检查了8个物种的叶和茎解剖,目的是确定诊断特征,以支持准确的物种划分和/或反映其栖息地的环境条件。此外,我们还基于59个宏观和微观形态特征进行了相似性分析。我们的研究结果表明,所研究的物种在茎特征(如有无翅膀和毛状体、皮层的层数、髓细胞的增厚或不增厚)和叶片特征(如正面表皮细胞的轮廓、气孔的排列和类型、乳头的存在或不存在、中脉的轮廓、叶柄和中脉的厚壁组织、纤维和/或硬核的存在或不存在、维管束的存在或不存在、后者的皮层层数等)上存在差异。栅栏和海绵状薄壁组织的比例和分布,以及叶缘的形状、组成和方向。其他性状似乎与环境适应有关,包括水分限制、光反射和扩散(如角质层和细胞壁厚度、毛状体、乳头状体、下气孔叶)、机械支撑(如纤维、硬核)、光合效率(如两气孔叶)、能量储存(如淀粉粒)以及对草食和渗透调节的防御(如毛状体、芦苇)。相似性分析显示了两个形态学上的聚类,这部分符合先前的系统发育研究。这些发现扩大了对所检种的解剖学认识,并为今后对余甘菊的药理学、分类学、系统发育和生态学研究奠定了基础。

Diverse floral arrangement morphs of Spiranthes sinensis (Orchidaceae) enhance pollinator visitation and reproductive success when competing with syntopic co-flowering plants 在与同花共花植物竞争时,螺旋体的不同花型提高了传粉者的访花率和繁殖成功率

Estimating the effects of diverse arrangements of flowers within inflorescence on intra- and inter-specific pollinator visitation and plant reproductive success is key to understanding the biodiversity and coexistence of sympatric co-flowering plants. In this study, we examined the effects of diverse floral arrangement morphs on pollinator visitation and plant reproductive success in two syntopic co-flowering plants through experimental arrays. For this purpose, we used an orchid species (Spiranthes sinensis) characterized by three floral arrangement morphs (clockwise, anticlockwise and vertical) and a syntopic co-flowering plant (Prunella vulgaris). We constructed 15 synthetic arrays that included single or three floral arrangement morphs of S. sinensis and transplanted with P. vulgaris at a common-garden site to estimate pollinator visitation and reproductive success. The results indicated that transplantation with P. vulgaris reduced the fruit set of S. sinensis. When S. sinensis was transplanted with P. vulgaris, the combination of the three floral arrangement morphs of S. sinensis improved the pollinator visitation of the anticlockwise and vertical morphs and improved the weight of the seeds per fruit of the clockwise morph compared with the single floral arrangement morph. For P. vulgaris, pollinator visitation was greater when it was transplanted with a combination of three floral arrangement morphs of S. sinensis than when it was transplanted with one floral arrangement morph of S. sinensis. The results highlight the effects of diverse floral arrangement morphs in interspecific competition for pollinators. More generally, the results imply the potential role of diverse floral arrangement morphs in maintaining the coexistence of syntopic co-flowering and pollinator-sharing plants.
了解不同花序内花的排列方式对种内和种间传粉者访视和植物繁殖成功的影响是了解同域共花植物生物多样性和共存的关键。本研究通过实验阵列,研究了两种同花共花植物的不同花型对传粉者访花和植物繁殖成功的影响。为此,我们选用了一种具有顺时针、逆时针和垂直三种花型的兰花(Spiranthes sinensis)和一种同花共花植物(Prunella vulgaris)。我们构建了15个人工合成阵列,包括单种或三种花的排列形态,并将其移植到普通园林中,以评估传粉者的访花率和繁殖成功率。结果表明,植栽可使金银花坐果数量减少。三种花型组合移植后,与单一花型相比,顺时针花型和垂直花型的传粉者访花率显著提高,单果种子重量显著提高。与三种不同花型组合移植比与一种不同花型组合移植时,访粉者访问量更大。研究结果强调了不同花型在种间传粉者竞争中的作用。更普遍的是,这些结果暗示了不同的花形态在维持同花共花和传粉者共享植物共存中的潜在作用。

Female gametophyte and endosperm development in Jurinea kilaea Azn. (Asteraceae) 朱里亚雌配子体与胚乳发育。(菊科)
IF 1.8 4区 生物学 Q3 ECOLOGY Pub Date : 2026-03-01 Epub Date: 2026-01-10 DOI: 10.1016/j.flora.2026.152924

In this study, female gametophyte and endosperm development in Jurinea kilaea, which grows naturally in sea dunes in a very limited area in Türkiye and Bulgaria, were investigated cyto-embryologically for the first time using light microscopy methods. J. kilaea has an inferior, unilocular, bicarpellary and syncarpous ovary as in other previously studied Asteraceae members. Only one ovule develops in the ovary, and this also has basal placentation. The ovule is anatropous, unitegmic and tenuinucellate type. The megaspore mother cell develops directly from the archespore cell. The megaspore mother cell undergoes meiosis to form a linear tetrad. Of these four megaspores, the megaspore on the chalaza side forms the active megaspore, the others become atrophied. The active megaspore undergoes mitotic divisions and forms the Polygonum type embryo sac. Mature embryo sac contains an egg apparatus on the micropylar side, the central cell with two polar nuclei and three antipodes on the chalazal side. The egg apparatus includes two synergid cells and one egg. Polar nuclei are located close to the egg apparatus. Antipodal cells can each have more than one nucleus. Towards the end of megasporogenesis, in the tetrad stage the integumentary tapetum is seen surrounding the embryo sac. Endosperm development is initially of the nuclear type but later turns into the cellular type.
本研究首次利用光学显微镜技术对生长在保加利亚和保加利亚基伊岛有限地区沙丘上的朱里亚(Jurinea kilaea)的雌性配子体和胚乳发育进行了细胞胚胎学研究。与其他先前研究过的菊科植物一样,菊属植物具有下位、单室、二元制和合心子房。在子房中只有一个胚珠发育,这也有基部着床。胚珠倒生,单胞,具腱核型。大孢子母细胞直接由原孢子细胞发育而来。大孢子母细胞减数分裂形成线形四分体。在这四个大孢子中,合带侧的大孢子形成活跃的大孢子,其他的大孢子萎缩。活跃的大孢子进行有丝分裂,形成蓼型胚囊。成熟的胚囊在卵孔一侧包含一个卵器,中心细胞在合点侧具有两个极核和三个对跖体。卵器包括两个协同细胞和一个卵。极核位于卵器附近。对跖细胞可以有一个以上的细胞核。大孢子发生末期,在四分体阶段,胚囊周围可见被绒毛绒毡层。胚乳发育最初为核型,后来转变为细胞型。

Vanilla Plumier ex Miller is a pantropical genus of Orchidaceae with high global economic value. Vanilla planifolia Andrews, the main species used in commercial vanilla production, faces challenges including a narrow genetic base, susceptibility to pathogens, and vulnerability to climatic, ecological, and anthropogenic threats. These limitations highlight the need to cultivate alternative species. Brazilian species such as Vanilla chamissonis Klotzsch, Vanilla cribbiana Soto Arenas, and Vanilla phaeantha Rchb.f. produce aromatic fruits containing vanillin-related compounds, suggesting their potential for commercial use. However, their agronomic traits remain poorly understood, and accurate identification is hindered by the ephemeral nature of floral organs, limiting classification outside the reproductive phase. To address these gaps, we compared these three Brazilian species with V. planifolia. Our analysis revealed shared anatomical traits, including a uniseriate epidermis, mycorrhizae in roots, stem stomata, and collateral vascular bundles in leaves, as well as important differences. V. phaeantha showed unique exodermal wall thickening, suggesting intraspecific variation in defense traits. All species had a uniseriate, continuous, suberized endodermis in roots, with “U” shaped wall thickening in V. phaeantha and V. planifolia, and “O” shaped in V. chamissonis and V. cribbiana, the latter potentially offering greater resistance to fungal invasion. Documenting the anatomical diversity of Brazilian Vanilla species reveals functional adaptations and provides a foundation for future studies on their physiological and agricultural potential. These insights contribute to sustainable cultivation and conservation efforts and may expand the commercial use of Vanilla beyond V. planifolia.
香草属是兰科泛热带植物,具有很高的全球经济价值。作为商业香草生产的主要品种,planifolia Andrews面临着遗传基础狭窄、对病原体易感性、易受气候、生态和人为威胁等挑战。这些限制突出了培育替代物种的必要性。巴西品种,如香草香薷Klotzsch,香草cribbiana Soto Arenas和香草phaeantha Rchb.f。生产含有香草素相关化合物的芳香水果,这表明它们具有商业用途的潜力。然而,它们的农艺性状仍然知之甚少,并且由于花器官的短暂性阻碍了准确的鉴定,限制了生殖期以外的分类。为了解决这些差距,我们将这三种巴西物种与平叶卷叶植物进行了比较。我们的分析揭示了相同的解剖学特征,包括单根表皮,根中的菌根,茎气孔和叶中的侧维管束,以及重要的差异。phaeantha表现出独特的外表皮壁增厚,表明防御性状在种内存在差异。所有种的根内胚层均为单根的、连续的、被剥落的内胚层,其中phaeantha和planifolia的壁增厚为“U”型,而chamissonis和V. cribbiana的壁增厚为“O”型,后者对真菌侵袭的抵抗能力更强。记录巴西香草物种的解剖多样性揭示了功能适应,为其生理和农业潜力的未来研究奠定了基础。这些见解有助于可持续栽培和保护工作,并可能扩大香草的商业用途。

Plants inhabiting high-elevation environments often experience pollinator limitation and may favor autonomous self-pollination (ASP) as a reproductive assurance mechanism. Although ASP occurs in ∼20% of orchids, its mechanisms remain poorly understood in tropical montane species. In this study, we investigated the occurrence and mechanism of ASP in a high-Andean orchid (Ponthieva similis). We hypothesized that ASP yields higher fruit set than natural pollination in emasculated flowers, ensuring reproductive success. We used histochemical tests to detect floral secretory tissues, monitored diurnal floral visitors, and conducted an emasculation experiment to evaluate the contribution of ASP and pollinators to reproductive success. The breeding system was analyzed using controlled pollination treatments and seed viability. Finally, floral buds and pollen tube growth were examined to characterize the ASP mechanism. We did not detect secretory tissues in the small, whitish flowers of P. similis, and no diurnal floral visitors were observed. In the experiment, emasculated flowers had lower fruit set (13.33%) than unmanipulated (100%) and manipulated controls (86.67%), indicating pollinator limitation. All controlled pollination treatments produced high fruit set except emasculation. However, seeds from ASP showed 29% higher viability than those from hand cross-pollination, suggesting outbreeding depression. ASP occurred within floral buds and was mediated by early withering of the anther cap and filament, which transported pollinia to the stigma, characterizing a novel prior ASP mechanism. Our study provides the first empirical evidence of prior ASP in a tropical montane orchid, underscoring its role as an adaptive strategy under pollinator limitation in high-elevation environments.
生活在高海拔环境中的植物往往受到传粉者的限制,因此可能倾向于采用自主自花授粉(ASP)作为生殖保证机制。虽然ASP发生在约20%的兰花中,但其机制在热带山地物种中仍然知之甚少。在本研究中,我们研究了高安第斯兰(pon窃贼相似)中ASP的发生及其机制。我们假设ASP在去势花中产生比自然授粉更高的坐果量,从而确保生殖成功。采用组织化学方法检测花的分泌组织,监测花的昼夜访花情况,并通过去雄实验来评估ASP和传粉者对繁殖成功的贡献。采用控制授粉处理和种子活力对该育种系统进行了分析。最后,通过花蕾和花粉管的生长情况来研究ASP的机制。我们没有在小的,白色的花中检测到分泌组织,也没有观察到白天的花访客。实验结果显示,去势花坐果率(13.33%)低于未处理花(100%)和处理花(86.67%),表明授粉者有限。除去雄外,所有对照授粉处理均产生高坐果。而手工异花授粉的种子活力比手工异花授粉的种子活力高29%,表明异花授粉的种子远交性较差。ASP发生在花蕾内,通过花药帽和花丝的早枯介导,将花粉传递到柱头,这是一种新的ASP前期机制。本研究首次为热带山地兰花提供了先验ASP的经验证据,强调了其在高海拔环境中传粉者有限的适应策略中的作用。

Zingiber engganoense Ardiyani is a critically endangered species that occupies a restricted habitat on Enggano Island. A single location was reported in a previous study. Due to the lack of information about the current population status, surveys were used to find new populations and improve our understanding of its conservation status. Surveys were conducted centered on the known location reported from the previous study, then expanding into surrounding areas and also surveying locations informed by local people. The study area covered two villages: Malakoni and Banjarsari. These locations are surveyed based on historical records and local information. A purposive sampling method was applied to assess the population and habitat characteristic of Z. engganoense Ardiyani. The population was quantified and physical variables were measured inside the plots. The coordinate points and spatial environmental layers were used as input of a model for predicting habitat suitability of the species. An ensemble model was constructed by aggregating the results of three algorithms: Random Forest (RF), Multivariate Adaptive Regression Spline (MARS), and Generalized Linear Model (GLM) to generate a habitat suitability map. Six new occurrence locations in Malakoni village were identified with the surveys. The ensemble model predicted 18 km2 of moderately suitable habitat and 3 km2 of highly suitable habitat on the island. Our model predicted only 4 km2 of moderately suitable habitat was located inside a protected area of Taman Buru Gunung Nanu’ua. Three input variables were identified as important for habitat suitability: soil organic carbon, elevation and annual precipitation. The predictive model resulted from this study was categorised as an effective model with an AUC value of 0.90 and a TSS value of 0.88. We propose CR B1ab(iii)+B2ab(iii), D as the new conservation status of Z. engganoense Ardiyani. Cuttings from four individuals and two tubers that were secured from the wild, all successfully grew under controlled conditions in the greenhouse of the botanic gardens.
engganoense Ardiyani是一种极度濒危的物种,在Enggano岛上有一个有限的栖息地。在之前的一项研究中报告了一个单一的位置。由于缺乏有关种群现状的信息,通过调查来发现新的种群,提高我们对其保护状况的了解。调查以先前研究报告的已知地点为中心,然后扩展到周围地区,并调查当地人告知的地点。研究区域包括两个村庄:Malakoni和Banjarsari。这些地点是根据历史记录和当地信息进行调查的。采用目的抽样的方法,对滇地黄颡鱼种群和生境特征进行了调查。对种群进行了量化,并测量了小区内的物理变量。利用坐标点和空间环境层作为模型的输入,对该物种的生境适宜性进行了预测。将随机森林(Random Forest, RF)、多元自适应样条回归(Multivariate Adaptive Regression Spline, MARS)和广义线性模型(Generalized Linear model, GLM) 3种算法的结果综合起来,构建了一个集成模型,生成了栖息地适宜性图。通过调查确定了马拉科尼村6个新的发病地点。集合模式预测了岛上中度适宜生境18 km2,高度适宜生境3 km2。我们的模型预测,在Taman Buru Gunung Nanu 'ua保护区内只有4 km2的中等适宜栖息地。土壤有机碳、海拔高度和年降水量是影响生境适宜性的重要输入变量。本研究建立的预测模型AUC值为0.90,TSS值为0.88,属于有效模型。我们提出CR B1ab(iii)+B2ab(iii), D作为新保护状态。在植物园温室的控制条件下,从四个个体和两个从野外获得的块茎上成功地生长。
