To cope with environmental stresses, plants have developed specialized cell wall structures called cuticles at the interface between the plant and the environment. In Arabidopsis thaliana seedlings, cuticles cover and protect aerial organs and young roots. However, the precise assembly of the molecular machinery required for cuticle formation on the surface of distinct organs that exhibit entirely different functions and developmental contexts remains unknown. Here, we demonstrate that a paralogous gene pair, ARABIDOPSIS THALIANA MERISTEM LAYER1 (ATML1) and PROTODERMAL FACTOR2 (PDF2), regulates precise cuticle formation in Arabidopsis thaliana seedlings. We found that the expression of ATML1 and PDF2 spatially overlapped with cuticle deposition in Arabidopsis thaliana seedlings. Furthermore, the loss of ATML1 and PDF2 activity resulted in a significant downregulation of the expression of genes required for cuticle formation and compromised cuticle formation in different organs. Seedlings with impaired activities of ATML1 and PDF2 exhibited higher susceptibility to environmental stress. In particular, PDF2 plays a predominant role in tolerance to environmental stress rather than ATML1 in the roots. Collectively, our study provides new insights into the regulatory mechanisms of cuticle formation and the developmental strategies plants use to protect their bodies from environmental stresses.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"303-313"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142807190","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}

Thus, its flowers are usually large, showy, red or yellowish, offering nectar as the principal resource. There are two main interaction systems with birds in Erythrina: in one, the inflorescences are erect and the flowers are horizontal, offering no landing platform; in the other, the inflorescences are horizontal and the flower parts are more exposed. Erythrina speciosa is pollinated by hummingbirds and E. poeppigiana is pollinated by passerines. Despite their structural variation, little is known about how species of the same genus diverge ontogenetically to form flowers adapted to pollinators with different beak morphology and feeding behaviors. Therefore, this study aimed to investigate floral development in two species according to their pollination system. Flowers and buds were collected and fixed for analysis using scanning electron microscopy and light microscopy. Some characteristics are common to both species: the formation of a pseudoracemose inflorescence, the unidirectional emergence of floral organs, and the formation of a short staminal sheath involving nine of the ten stamens (diadelphous androecium). Other characteristics, notably those related to the late stages of floral development, gradually diverged. Among them are inflorescence formation pattern; the formation of reduced and free keel petals in E. speciosa, while in E. poeppigiana they are longer and postgenitally united by their lower margins; and the participation of the standard in the floral display. The studied species share several traits common to other Papilionoideae, but some similarities between the species studied may not be phylogenetically related and reveal the potential ontogenetic pathways of functional convergence that flowers have experienced throughout evolution in the genus.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"253-272"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142895395","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}

Waterlogging stress is one of the prominent abiotic stresses that has a significant impact on the yield and quality of barley. Seed germination plays a critical role in the establishment of seedlings and is significantly impacted by the presence of waterlogging stress. However, there is a limited understanding of the regulatory mechanisms of gene expression and metabolic processes in barley during the germination stage under waterlogging stress. This study aimed to investigate the metabolome and transcriptome responses in germinating barley seeds under waterlogging stress. The findings of the study revealed that waterlogging stress sharply decreased seed germination rate and seedling growth. The tolerant genotype (LLZDM) exhibited higher levels of antioxidase activities and lower malondialdehyde (MDA) content in comparison to the sensitive genotype (NN). In addition, waterlogging induced 86 and 85 differentially expressed metabolites (DEMs) in LLZDM and NN, respectively. Concurrently, transcriptome analysis identified 1776 and 839 differentially expressed genes (DEGs) in LLZDM and NN, respectively. Notably, the expression of genes associated with redox reactions, hormone regulation, and other biological processes were altered in response to waterlogging stress. Furthermore, the integrated transcriptomic and metabolomic analyses revealed that the DEGs and DEMs implicated in mitigating waterlogging stress primarily pertained to the regulation of pyruvate metabolism and flavonoid biosynthesis. Moreover, waterlogging might promote flavonoid biosynthesis by regulating 15 flavonoid-related genes and 10 metabolites. The present research provides deeper insights into the overall understanding of waterlogging-tolerant mechanisms in barley during the germination process.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"289-302"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143039124","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 turnover rates of Rubisco carboxylation (kcatc) under saturated-CO2 conditions in conifers and lycopods were comparable to those in the control C3 crops. Rubisco carboxylase activity under CO2-unsaturated conditions (vcu) was also measured using reaction mixtures saturated with a N2 gas containing CO2 and O2 at present atmospheric levels to predict the Rubisco CO2 affinity from the percentage of vcu in kcatc. The predicted CO2 affinity in conifers and lycopods tended to be lower than that in the control C3 crops. When the control C3 crops and two previously examined C4 crops were analyzed together, the kcatc of Rubisco with a low CO2 affinity tended to be high.

In conifers and lycopods, the kcatc was lower than that expected on the basis of predicted Rubisco CO2 affinity, unlike in the control crops. N allocation to Rubisco also tended to be lower than that expected on the basis of kcatc. These results indicate that Rubisco in the examined conifers and lycopods is not superior in terms of both kcatc and CO2 affinity and that the abundance of Rubisco is not necessarily closely related to its kinetic properties.

Aiton is a medicinal plant belonging to the family Apocynaceae as a core source of natural cardenolides. Cardiac glycosides (CGs) are steroid derivatives reported to have the ability to regulate cancer cell survival and death through multiple signaling pathways. Earlier stage-specific and wound-responsive accumulation of CGs and their genin units have already been reported. Recent cumulative evidences have implicated stress and defense response signaling in the production of secondary metabolite in plants. In this report, seasonal accumulation of CGs and its genin units have been explored along with their profiling under control vs stress conditions with a significant accumulation using LC-MS/MS. The study showed that Calotropis procera plants efficiently accumulate CGs and genin units in both winter and summer beside rainy season, as well as under thermal and salinity stress. Among the three cardenolides, the calotropagenin was accumulated more than coroglaucigenin and uzarigenin whereas CGs like calotropin, frugoside, uscharidin, uscharin, and asclepin were significantly accumulated in response to heat, cold and NaCl. Comparatively for hormonal treatments like methyl jasmonate and salicylic acid, targeted metabsolites showed upto twofold accumulation. Gene expression analysis of CG biosynthetic genes also validated the accumulation pattern of the targeted metabolite. This targeted metabolites accumulation enhances plant tolerance to adverse conditions. Gene expression analysis supports this strategy, emphasizing the plant's effective stress management. These findings significantly contribute to our understanding of how plants adapt to stress through the accumulation of metabolites, thereby enhancing their tolerance to challenging environmental conditions.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"347-364"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142950373","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}

TCW of MCs and BSCs almost did not differ among the C4 decarboxylation types (NADP-ME, NAD-ME, and PCK). In plants grown outdoors (51 species), similar trends of TCW were also found among photosynthetic groups, but their TCW was generally higher than that of growth-chamber plants.

To do so, photochemical reflectance index (PRI) is a potential measure to detect conversion of the xanthophyll cycle in photosystem II. Raphanus sativus var. raphanistroides is a wild radish species closely related to domesticated radish, and is distributed throughout the coastal regions of Japan, where it is thought to be salt tolerant. In this study, we raised wild and domesticated radishes under various salt conditions and assessed growth, photosynthetic status, and PRI. When grown at mild salt stress (50 mM NaCl), wild radish leaves showed photosynthetic activity levels comparable to control plants, whereas the photosynthetic activity of domesticated radish was suppressed. This result suggests that wild radishes are more salt-tolerant than domesticated radishes. Although photosynthetic rate and the photochemical quantum yield were significantly correlated with PRI in both species, the PRI resolution was insufficient to distinguish differences in salt tolerance between wild and domesticated radish. Wild radish had a lower maximum quantum yield (Fv/Fm) when grown under moderate salt stress (200 mM NaCl), suggesting chronic photoinhibition. The relationship between non-photochemical quenching (NPQ) and PRI was significant when leaves with chronic photoinhibition were eliminated but this relationship was not significant when they were included. In contrast, the relationship between photosynthesis and PRI was significant regardless of whether leaves displayed chronic photoinhibition or not. We conclude that PRI is useful to detect relatively large reductions in photosynthetic rate under salinity stress, and that care should be taken to evaluate NPQ from PRI.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"231-241"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11910433/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143033357","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, various populations respond differently to elevated nitrogen levels. This study explores the responses of central and edge populations of the annual invasive plant Galinsoga quadriradiata to different levels of nitrogen addition. The results indicate that the central population has a stronger need for nitrogen, with nitrogen addition promoting the growth of its aboveground parts, reducing intraspecific competition, and increasing reproductive allocation and total biomass. Specifically, nitrogen addition provides more nutritional resources, easing resource competition among plants, reducing intraspecific competitive pressure, and allowing plants to allocate more energy to growth and reproduction, thereby enhancing their expansion potential. In contrast, the edge populations respond differently to nitrogen. Although nitrogen addition promotes the growth of their underground parts and enhances root development, the impact on aboveground parts is smaller. The enhancement of underground parts helps edge populations better adapt to barren environments, improving their survival and competitive ability in new environments, thus increasing their expansion potential. Overall, the growth impact on edge populations due to nitrogen addition is smaller, possibly indicating they have exceeded their nitrogen limit. The study demonstrates that the degree of population differentiation in invasive plants at different invasion stages is a critical factor in studying their spread potential, aiding in predicting plant invasion trends under climate change and providing theoretical support for formulating targeted management strategies.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"243-251"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143189080","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}
