Research on the tricellular pollen of Arabidopsis thaliana revealed that chromatin is highly condensed and transcriptional activity is suppressed in sperm cells. However, comprehensive structural investigations involving generative cells of bicellular pollen have not been conducted. In this study, we provide relevant insights into other angiosperms that produce bicellular pollen. Lilium longiflorum, which has large and easily observable nuclei, was used for a detailed analysis of the chromatin structure and transcriptionally active regions in pollen and pollen tubes. Chromatin was condensed, resulting in a ribbon-like structure that was clearly visible in mature generative cell nuclei. Additionally, transcriptionally active regions were restricted to the intersections of chromatin as pollen desiccated. Although de novo transcription was revealed to be unnecessary for pollen tube growth, transcriptional activity temporarily resumed before generative cell division during pollen tube growth. Moreover, the inhibition of de novo transcription influenced changes in nuclear morphology. In this study, the distinctive chromatin structures and transcriptional activity states in generative cell nuclei of bicellular pollen were elucidated, with the generated data contributing to a deeper understanding of transcription and other regulatory mechanisms involved in pollen maturation and pollen tube growth.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"653-666"},"PeriodicalIF":2.7,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144031097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such an androecium is believed to have evolved through the loss of two stamens. However, there is still no consensus on the origin of eight-staminate androecium including the positions of the two lost stamens and the pathway of their reduction compared to other Sapindaceae. We examined the early stages of flower development in five maple species belonging to different sections - four species with eight stamens and one species with ten stamens - using scanning electron microscopy. Measurements were performed to analyze the relative positions of stamen primordia, their size, and the floral meristem surface area. In addition, the perianth and androecium vasculature was studied to reveal petal-stamen complexes. We found that in three of four 8-staminate species, three stamens are initiated from common petal-stamen primordia, and five arise from single primordia. In A. tegmentosum Maxim., four stamens appear from common primordia with petals, and four from single primordia. Despite developmental differences, stamen distribution within the flower and the angles between adjacent stamens indicate a similar androecium construction in all species. In most species with eight stamens, the differences between two andoecial whorls have vanished. In contrast, A. nikoense (Miq.) Maxim., with ten stamens, possesses two distinct stamen whorls, the antepetalous stamens are initiated from common primordia. In the 8-staminate androecia of the genus Acer, the same two stamens have been lost as in other Sapindaceae. Within genus Acer, there is a certain decrease in the relative size of the floral meristem, accompanied by an increase in the number of common petal-stamen primordia and increased heterogeneity of the androecium (in A. tegmentosum) or reduction of some floral organs.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"603-624"},"PeriodicalIF":2.7,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143999991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Xinjiang garlic exhibits visually normal development of both androecium and gynoecium, but most pollen grains are not viable, thus allowing for the identification of flower development-related genes through combined morphological, anatomical, and cytological methods with transcriptome analysis. The inflorescence meristem differentiation of Xinjiang garlic plants was initiated after the 6th-7th leaves emerged, implying the transition from vegetative growth to reproductive growth. With the development of flower organs after bolting, normal pollen mother cell meiosis but no viable pollen grains were detected through triphenyl tetrazolium chloride (TTC) staining. Delayed tapetal degeneration, the gap between the tapetum and the middle layer, and degenerating and aborting anther are visible during anther development. There were 25 differentially expressed MYB genes and 64 flowering pathway related genes at different stages of flower development. The R2R3-MYB genes enriched in Module 22 are involved in the development of the tapetum and pollen. The co-expression network analysis showed that most MYB genes are related to flowering regulatory genes. The expression pattern of MYB35, MYB26, MYB80 and MMD1 may cause delayed degradation of the tapetum, or abnormal development of the pollen wall leading to pollen abortion.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"637-651"},"PeriodicalIF":2.7,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143795749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While cuticular waxes play a pivotal role in plant adaptation to various environmental stresses, the specific roles of individual molecular species, particularly wax esters (WEs), remain poorly understood. In this study, we investigate the evolution and function of wax ester biosynthesis in land plants, focusing on the WSD (wax synthase/DGAT) enzyme family. We demonstrate that the ancestral origin of WSD enzymes traces back to streptophyte algae, specifically Klebsormidium nitens (KnWSD1). Our findings provide evidence that KnWSD1 functions as a monofunctional WSD catalyzing WE formation without producing triacylglycerols (TAGs). By generating Arabidopsis mutants with multiple WSD gene knockouts, we uncover a crucial role for WEs in supporting floral organ development under high humidity. Our results reveal that WEs are essential for floral organ development and provide new insights into their evolutionary significance in plant adaptation to terrestrial environments.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"497-509"},"PeriodicalIF":2.7,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12062176/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143763504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this term includes studies in which cold storage was possible until further processing in a laboratory. Previous studies proposing onsite RNA extraction methods are limited to descriptions of RNA purity, quantity, and quality, and lack a thorough evaluation of transcriptome quality, and transcriptomic evaluations of RNA storage solutions in plants are, to our knowledge, only available for periods of less than a day. This issue is critical for studying plants in geographically difficult-to-access regions, where keeping the cold chain is unrealistic. In this study, the transcriptome of the non-model plant Helonias orientalis (order: Liliales) was evaluated before and after storage of the leaf tissue for one and fourteen days at 25 °C in RNAlater and TRIzol, respectively. Additionally, field-friendly protocols were similarly evaluated for onsite plant RNA extraction at ambient temperature with lightweight equipment that can run on a portable generator, including a guanidine isothiocyanate-free protocol that is compatible with the polyphenol-rich wild strawberry Fragaria vesca. The quality of the transcriptome assembly after 1-day storage and our optimized onsite methods had similar results to that of the state-of-the-art. However, in terms of differential expression analysis, onsite extraction methods performed better overall than the stored tissue samples. We expect that our onsite RNA extraction methods will provide valuable insights into the transcriptional regulation of plants in areas where research equipment is difficult to access.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"511-524"},"PeriodicalIF":2.7,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12062031/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143573388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
