In crop science, FOT is critical for stress avoidance and efficient breeding practices. This study developed a system for the automatic detection of rice flower openings and FOT estimation by integrating a low-cost time-lapse camera with machine learning technology. This approach enabled high-resolution monitoring of flowering dynamics in two cultivars: the japonica cultivar Taichung 65 (T65) and the indica cultivar IR24. The system accurately identified regions containing open flowers, and the estimated FOTs varied within a 3-h range, with a root mean square error of approximately 30 min compared to manual detection. A significant difference in estimated FOTs between IR24 and T65 demonstrated the system's potential for genetic screening applications. FOT of both cultivars exhibited a significant negative correlation with daily mean temperature. Notably, a temperature-sensitive period was identified in the morning, suggesting that temperature influences not only flower opening but also preceding physiological processes such as panicle and spikelet development. This study presents a novel approach to investigating FOT dynamics in rice and provides insights into the interaction between environmental factors and internal regulatory mechanisms governing this critical reproductive trait.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144285049","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}

In this study, we have identified and cloned CrJAR1, a member of the Gretchen Hagen3 (GH3) gene family, from C. roseus and confirmed its enzymatic activity in JA-Ile formation via heterologous expression in E. coli. Functional analyses using transient overexpression and virus-induced gene silencing (VIGS) in C. roseus leaves revealed that CrJAR1 positively regulates the accumulation of catharanthine and vindoline. Moreover, we demonstrated that CrCOI1, the jasmonate receptor, functions synergistically with CrJAR1 in modulating TIA biosynthesis. Co-silencing of CrCOI1 and CrJAR1 resulted in a lower sensitivity to exogenous JA treatment compared to silencing of CrJAR1 alone, indicating distinct yet complementary roles in jasmonate-mediated metabolic regulation. These results advance our understanding the function of CrJAR1 and offer new strategies for engineering specialized metabolite biosynthesis in plants.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144234404","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}

The glands in the receptacle of Pseudobombax longiflorum (Malvaceae) are widely accepted as nectaries. Using light, scanning, and transmission electron microscopy, we studied the anatomy, histochemistry, ultrastructure, and secretory dynamics of the receptacle glands in this species. The glands were active in secretion from young flower buds to immature fruits. Trigona spinipes was the most abundant and frequent visitor. The glands were composed of a uniseriate epidermis covered with a thick cuticle and a multilayered parenchyma, exhibiting two subregions with abundant phloem in the innermost region. These glands produced sugars, resins, oils, and phenolic compounds. Glandular cells exhibited large nuclei with nucleoli, polymorphic plastids with lipophilic inclusions, numerous mitochondria, endoplasmic reticulum profiles, cytoplasmic oil bodies, and vacuoles containing phenolic compounds. Plasmodesmata indicate that secretory components are transported from cell to cell via the symplast. There is also evidence for granulocrine and eccrine secretion mechanisms. The accumulated secretions form a bulge in the central region of the gland. The bulged epidermis detached from the parenchyma cells, and the rupture of the epidermal cells released the accumulated hydrophilic components. Residual lipophilic secretions were embedded in the epidermal cell wall and cuticle. The receptacle glands of P. longiflorum are not typical nectaries but mixed glands that produce both hydrophilic and lipophilic secretions during floral development until young fruits.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144173929","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}

The foraging behaviour of insects, such as the invasive hornet Vespa velutina nigrithorax, introduced into northwestern Spain over a decade ago, may be influenced by floral volatiles. This hornet detects plant secondary metabolites, including semiochemicals, which aid in locating nectar, carbohydrates, prey, mating sites, and other resources. Understanding the volatile organic compounds (VOCs) emitted by plants visited by V. velutina may help to develop targeted control strategies. The aim of this study was to identify and analyse the volatile compounds emitted by 18 plant species frequented by V. velutina nigrithorax in the province of Ourense, northwest Spain. Solid-phase microextraction (SPME) coupled with gas chromatography-mass spectrometry (GC-MS) was used in this study. A total of 110 VOCs were identified, of which 21 compounds were abundant in the samples, with terpenes being the most abundant. Furthermore, a PLS-DA analysis selected 33 volatile compounds with variable importance scores (VIPs) greater than 1, in particular methylanthranilate with a value of 1.81. Eleven of these compounds were found to be abundant in the analysed samples, including (Z)-β-ocimene; 1-octen-3-ol; 3-hexen-1-ol, acetate, (Z)-; 3-octanone; eugenol; linalool; methyl salicylate; o-cymene; α-farnesene; α-terpineol and β-farnesene.

The study was conducted in CSS (19°57'29″ S and 44°25'29″ W) and an SSF fragment (19°53'84″ S and 44°25'56″ W) in Minas Gerais, Brazil. The research focused on four species: Miconia albicans and Xylopia aromatica, which occur in both environments, as well as Bauhinia cfr. ungulata (CSS) and B. cfr. rufa (SSF). Shoots from the main axis were manually dissected, and budbreak times were recorded. Crown architecture was evaluated based on diagrams of the vegetative above-ground structure, excluding leaves. Light intensities was measured with a luxmeter at the crown's apex, interior, and base. Shoots were larger and had more preformed organs in CSS than in SSF trees. Trichomes were observed on shoots of all CSS and SSF trees. The number of cataphylls varied: B. cfr. ungulata had one, B. cfr. rufa had 1-3, while compound buds of X. aromatica averaged 5.4 in CSS and 3.7 in SSF. Simple buds of X. aromatica and all M. albicans buds lacked cataphylls. Budbreak occurred in September for M. albicans (CSS and SSF), October for B. cfr. ungulata, Juy-October for X. aromatica and August-October for B. cfr. rufa. A positive correlation between budbreak and rainfall was recorded only for B. cfr. ungulata. Despite differences in bud size and composition between environment, these didn't result in distinct crown architectures. The findings highlight that tropical woody species with cataphyll-protected buds are as common as in temperate regions.

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}
