In this study, we investigated the mutualistic interaction between an alpine ginger Roscoea purpurea and a long-tongued tabanid fly Philoliche longirostris across eight populations in central Nepal. We measured the flower and fly traits, assessed the visitation behaviour and frequencies of P. longirostris, and quantified the reproductive success of R. purpurea. Our results revealed that in three of the eight populations both nectar distance and corolla-tube length were longer than the fly proboscis length, indicating a clear mechanical mismatch between the interacting traits of plants and the fly. The visitation frequencies of the fly to R. purpurea flowers were substantially lower in the three populations compared to the other five populations, yet the fly did not visit any co-flowering species. In the three populations, the pollen limitation indices for both fruit set and seed set were over 0.95 indicating that plant reproduction was severely pollen limited. We suggest that if the mechanical mismatch is a persistent feature of the populations, it may eventually lead to a mutualism breakdown between R. purpurea and P. longirostris, which would have severe consequences for the existence of both organisms, particularly in the populations encountering mechanical mismatch between the interacting traits.</p>","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149181872","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}

Solanum (Solanaceae) presents typically pentamerous flowers, while some species can present meristic variations. S. hexandrum is a species with typical hexamerous flowers, which represents a fixed trait in some population, while its closely related species S. sublentum exhibit the typical pentamerous flower. Importantly, both species show meristic lability, indicating that floral organ number is flexible within the group. This study investigates the developmental basis for merism variation in these species by comparing the floral ontogeny across three populations of S. hexandrum and S. sublentum. We used scanning electron microscopy, Nano-CT analysis and floral anatomy to analyse the meristem size, floral development and floral vascularization to understand the pressures influencing this morphology and its impacts on floral architecture. We found that merism variations (in a range of tetramery to heptamery) is strongly correlated with floral meristem size. Populations with larger meristems exhibited supernumerary organs, while those with smaller meristems showed subnumerary organs or stable pentamery. The meristic changes were predominantly isomerous across the whorls. Flower ontogenesis also differed among populations and species, directly influencing the final flower form. Our result demonstrates that merism size and spatio-temporal developmental constraints are key factors shaping meristic lability in Solanum.

The basic helix-loop-helix (bHLH) transcription factor family plays pivotal regulatory roles in plant growth, development, and stress responses. This study identifies a novel member of the bHLH family, referred to as VabHLH015, isolated from Vitis amurensis 'Zuoshan-1'. The physicochemical properties, conserved domains, and evolutionary relationships of VabHLH015 were thoroughly analyzed. Additionally, Arabidopsis thaliana and Vitis vinifera 'Chardonnay' calli overexpressing VabHLH015 were generated to evaluate their cold stress tolerance. Amino acid sequence analysis indicated that the VabHLH015 protein comprises 491 amino acids, containing the bHLH-MYC_N and bHLH_AtAIB_like domains. Tissue-specific expression analysis demonstrated differential expression of VabHLH015 across various grapevine organs, with transcript levels markedly increasing in response to low temperature and multiple exogenous hormones. Subcellular localization confirmed that VabHLH015 is a nuclear protein. A transcriptional activation assay showed that it possesses autoactivation activity. Functional analyses revealed that transgenic A. thaliana and grape calli overexpressing VabHLH015 exhibited heightened sensitivity to cold stress. In comparison to wild-type controls, these transgenic lines displayed significantly elevated malondialdehyde (MDA) content and electrolyte leakage, alongside diminished activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT), as well as reduced proline (Pro) accumulation. Moreover, the expression levels of several cold-responsive genes were significantly downregulated in the transgenic lines. In summary, the overexpression of VabHLH015 attenuates plant tolerance to low temperatures by modulating the expression of cold tolerance-related genes and antioxidant enzyme activities. This study offers a novel candidate gene and provides a theoretical framework for elucidating the molecular mechanisms underlying cold tolerance, facilitating the breeding of cold-tolerant grapevine varieties.</p>","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149111115","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}

Therefore, elucidating the response and regulatory mechanisms of plants to Cd stress is essential for controlling the safety of agricultural and animal products at the source. In this study, we used a Cd-tolerant alfalfa cultivar, Medicago sativa 'Zhaodong' (ZD), and a Cd-sensitive cultivar, M. sativa 'Zhongmu No.1' (ZM), to investigate their differential responses to Cd stress in terms of morphology, photosynthetic function, and oxidative damage through combined physiological and RNA-Seq analyses. The results indicated that Cd stress inhibited leaf growth and photosynthetic function, and increased oxidative damage in alfalfa. The Cd-tolerant cultivar ZD exhibited greater tolerance compared to the Cd-sensitive cultivar ZM. RNA-Seq analysis revealed that the differentially expressed genes (DEGs) between the two cultivars under Cd stress were predominantly enriched in photosynthesis-related KEGG and GO pathways. Based on RNA-Seq and weighted gene co-expression network analysis (WGCNA), the MEgreen module exhibiting the highest correlation with physiological traits such as biomass and photosynthetic function was identified. The DEGs in this module were predominantly enriched in pathways related to photosynthesis and plant hormone signal transduction. Furthermore, a key gene, MsERF15, which regulates photosynthesis and ROS metabolic homeostasis in alfalfa under Cd stress, was identified. Although heterologous expression of MsERF15 significantly increased plant height in transgenic tobacco, it markedly reduced Cd stress tolerance, particularly by decreasing chlorophyll content and photochemical reaction center activity in the leaves under Cd stress, as well as elevating ROS accumulation. The potent growth-promoting effect of MsERF15 may represent a key factor contributing to its reduced Cd stress tolerance. In summary, our findings demonstrate that MsERF15 negatively regulates Cd stress tolerance in alfalfa. These results provide new insights into the adaptation mechanisms of alfalfa under Cd stress and offer a novel target for genetic improvement of Cd resistance in this important forage crop.</p>","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149111213","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}

Beyond altering gene networks, environmental stresses can activate transposable elements to generate genetic and epigenetic variation. For example, the heat-responsive retrotransposon AtCOPIA78 (ONSEN) mobilizes in RNA-directed DNA methylation (RdDM)-defective backgrounds. Although ONSEN mobilization generates heritable phenotypic variation, its role in flowering remains unclear. In this study, we examined the impact of stress-activated ONSEN mobilization on flowering-time regulation using nrpd1 mutant backgrounds. By screening ONSEN-mobilized nrpd1 populations, we identified an early-flowering mutant, designated YUNOHANA which flowered earlier than the parental nrpd1 mutant despite sharing the same RdDM defect. The early-flowering phenotype was associated with reduced expression of the floral repressor FLOWERING LOCUS C (FLC) and increased expression of the floral activator FLOWERING LOCUS T (FT). Genome-wide analysis identified multiple ONSEN insertion sites in yunohana (yuno), though none resided within known flowering-time regulatory genes. Segregation-based genotyping of early-flowering F2 plants prioritized a subset of candidate loci, including insertion sites near AT1G50130, AT1G07240, and AT3G22100, although no single tested insertion fully co-segregated with the phenotype. Transcriptome profiling revealed that yuno retained a global expression pattern largely like that of nrpd1, with differences restricted to few loci. Furthermore, ONSEN transcript and extrachromosomal DNA levels were reduced in yuno than nrpd1, indicating suppressed transposon activity following mobilization. Together, our findings suggest that stress-activated ONSEN mobilization can be associated with heritable developmental variation without widespread transcriptional disruption and identify candidate loci potentially linked to flowering-time regulation.</p>","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149111121","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}

We recorded seven floral traits of 1,945 flowers from 77 populations (12 native and 65 non-native) throughout the world distribution range to analyze their differentiation between the native and non-native ranges. Non-native populations of D. stramonium presented lower herkogamy than native populations, in agreement with the hypothesis of reproductive assurance under non-reliable pollinator environments. Corollas were unexpectedly larger in the non-native than in the native range, which could be attributed to high nutrient and water inputs in agroecosystems, the most common habitat of non-native populations. The phenotypic variation within populations was lower in the non-native range, which is congruent with the occurrence of founder events during the introduction or subsequent drift. Floral color showed a significant differentiation between native and non-native populations, probably due to founder events. The lack of association between floral color and herkogamy indicates that their differentiation between ranges is due to different and independent processes.

Seedlings were primed with mild heat or a 30-min T2H pulse, recovered for 2 days, and challenged with lethal heat. T2H pretreatment improved survival in both genotypes. Survival analysis and image-based quantification of projected green area showed that T2H-supported recovery was retained in hsfa2, whereas recovery after mild-heat priming was reduced. Total chlorophyll content showed the same genotype-dependent pattern: it was lower in hsfa2 than in Col-0 after mild-heat priming but did not differ between genotypes after T2H. Early reverse-transcription quantitative PCR (RT-qPCR) analysis showed that transcript levels of HSFA1A, HSFA1B, HSFA1D, HSFA1E, and HSP101 did not correlate with the observed survival response. In a separate recovery-period analysis, HSP101 transcript abundance in hsfa2 was significantly lower than in Col-0 after both priming treatments, with the larger reduction after T2H despite strong mutant protection. RNA sequencing (RNA-seq) revealed distinct transcriptional responses between heat and volatile priming: mild heat induced broad transcriptome remodeling, whereas T2H induced a more selective stress-associated response enriched in detoxification- and redox-associated, immune-associated, and hypoxia-like transcript categories.
