This study investigated two common bean (Phaseolus vulgaris) genotypes, Guaymí (high Fe-accumulating, HI) and Matambú (low Fe-accumulating, LI) to understand physiological and genetic mechanisms underlying Fe uptake, shoot accumulation, and adaptation under low and adequate Fe conditions. Plants were grown under controlled Fe-deficient and Fe-sufficient conditions. Root-induced acidification, ferric reductase activity, leaf chlorosis, and Fe and Mn accumulation were measured. Gene expression of Fe-related transporters and mobilisation pathways was assessed at early and prolonged stages of deficiency. Under Fe deficiency, HI showed stronger root acidification, higher ferric reductase activity, and greater Fe uptake compared with LI. HI maintained growth, leaf Fe, and Mn content, whereas LI relied on polyphenol-based Fe mobilisation. Early-stage Fe-related gene expression differed between the two genotypes but converged under prolonged deficiency. The HI genotype demonstrates superior Fe absorption efficiency and adaptive responses under Fe-limited conditions, sustaining growth and Fe accumulation in roots and shoots. These findings highlight the potential of selecting or engineering Fe-efficient cultivars to improve crop productivity and nutritional quality, offering a promising strategy to address Fe deficiency in agriculture and human diets.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148147635","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}

However, few studies have examined whether such parental effects differ between genotypes and whether they enhance both growth and defence. We conducted a two-generation herbivory experiment using six genotypes of the invasive clonal plant Hydrocotyle verticillata and the native generalist herbivore Spodoptera litura in China. We tested how parental herbivory (PH) effects influence offspring survival, growth, and herbivory defence, and whether these parental effects vary among genotypes. Herbivory significantly reduced leaf mass and leaf number of parental plants, while increasing its specific leaf area. PH enhanced offspring survival by 21% and tended to increase offspring leaf mass. However, clonal offspring from herbivory-treated parental plants suffered equally severe defoliation (>95%) as control offspring. While most parental effects were consistent across genotypes, root mass and specific leaf area showed genotype-dependent responses. Notably, genotype G4 exhibited markedly elevated SLA following PH despite having the lowest offspring survival. Our results reveal an asymmetric transgenerational strategy in invasive H. verticillata, that is, PH enhances offspring growth and survival without conferring herbivory defence. This decoupling of growth enhancement from defence induction represents an evolutionary trade-off that may facilitate rapid colonization but leaves invasive populations vulnerable to herbivore pressure. Consequently, while this transgenerational plasticity facilitates range expansion and population establishment in herbivore-free habitats, it may render invasive populations susceptible to regulation by specialist or generalist herbivores during secondary contact.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":"1109-1118"},"PeriodicalIF":3.6,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146163236","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}

Here, we evaluated the fitness of the parental tree species, Dimorphandra exaltata and D. mollis, and their hybrids, identified as D. wilsonii, in a hybrid zone from an ecotonal area between the Cerrado (savanna) and Atlantic Forest. We aimed to answer two principal questions: Do the hybrids express heterosis or hybrid breakdown? Do patterns of seed germination of hybrids suggest local adaptation or intrinsic hybrid incompatibilities? We analysed biometry of fruit and seed traits and germination response to a wide temperature range (12-40 °C) to assess the fitness of F1 and backcross compared to parental species. We identified heterosis in F1 hybrids, since their fruits were almost a third larger, and their seeds heavier than both parental species. The backcross hybrid showed a loss of vigour in fruit traits compared to F1. A much lower number of filled seeds per fruit, with a high ratio of malformed seeds/total seeds per fruit and a lower germination in almost all temperatures was found in the backcross compared to parental species and F1. These results suggest a hybrid breakdown. The heterosis found in the F1 hybrids coupled with the hybrid breakdown in backcross suggests that the maintenance of hybrid zone is dependent on the recurrent crossing between D. exaltata and D. mollis. The rarity of advanced generations of hybrids can be explained at least partially by intrinsic incompatibility, independent of the environment, consistent with intrinsic post-zygotic reproductive isolation.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":"1119-1128"},"PeriodicalIF":3.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146199716","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 employed comparative physiological assays, virus-induced gene silencing (VIGS) of SlTAT, and integrated multi-omics analysis (RNA-seq and LC-MS/MS) to characterize drought response mechanisms in SH versus AC under controlled drought conditions. SlTAT was identified as a critical regulator enriched in amino acid and alkaloid biosynthesis pathways. Silencing SlTAT in AC significantly impaired drought tolerance (P < 0.01), concurrently altering expression of antioxidant and secondary metabolism genes and reducing accumulation of protective metabolites. SlTAT enhances drought tolerance by synchronizing antioxidant defences with metabolic reprogramming in amino acid and alkaloid pathways. These findings provide novel targets for improving crop resilience through secondary metabolite engineering.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":"1052-1061"},"PeriodicalIF":3.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146206082","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 microbial interventions and Se fertilization are recognized as effective strategies, their integrated effects on Se translocation dynamics from early growth stages to mature grains remain understudied. This study investigates the synergistic potential of Funneliformis mosseae and selenite application during the seedling stage to enhance Se accumulation efficiency and grain biofortification. A pot experiment using typical paddy soil evaluated four treatments: control (CKSe0), F. mosseae alone (FSe0), selenite alone (CKSe0.5), and combined F. mosseae and selenite (FSe0.5). Plant biomass, Se concentrations in tissues/grains, rhizosphere microbial communities (16S/ITS sequencing) and soil Se fractions were analysed. FSe0.5 increased shoot/root dry weights by 104.5%/79.4% (P < 0.05) compared to CKSe0, with 2.5-fold (shoots) and 6.4-fold (roots) Se enrichment. Meanwhile, the content of available selenium in soil (SOL-Se + EX-Se) increased by 78.9% (P < 0.05). Microbiomic analysis showed FSe0.5 reshaped soil microbial communities, enriching Se-redox functional taxa (e.g. Massilia, Fusicolla). This accelerated the transformation process of bioavailable selenium fractions in the soil, thereby promoting efficient selenium accumulation in mature grains. Additionally, inoculation with F. mosseae played a dominant role in driving changes in the rhizosphere microbial community, with the fungal community shifting from a stochastic to a deterministic process. This study identifies seedling-stage F. mosseae-Selenite synergy as a critical strategy for optimizing Se biofortification. By coordinating microbial community restructuring with plant Se uptake dynamics, our findings provide a sustainable framework for enhancing agricultural Se utilization efficiency.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":"1129-1144"},"PeriodicalIF":3.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146163215","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 aimed to elucidate how L. chinensis orchestrates its defence response at the molecular level. We conducted integrated transcriptomic and metabolomic profiling to identify key changes in gene expression and metabolite levels. Our focus was on the modulation of flavonoid biosynthesis and phytohormone signalling pathways, which are crucial for stress adaptation. Our analyses revealed significant modulation in flavonoid biosynthesis, which is known for its role in plant defence mechanisms. Additionally, we observed changes in phytohormone signalling pathways that are essential for growth regulation and stress response. Characterization of the Aux/IAA gene family identified LcIAA3 as a key player in the mowing stress response, with its expression consistently upregulated. The modulation of flavonoid biosynthesis and phytohormone signalling pathways under moderate mowing intensity is central to L. chinensis's enhanced regrowth. LcIAA3, which is upregulated post-mowing, is likely involved in these processes and may be a significant factor in the plant's stress response. Further functional validation is necessary to confirm its role. Our study provides valuable insights into the molecular mechanisms of mowing tolerance and potential breeding targets for improving the resilience of forage crops under moderate mowing conditions.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":"1178-1189"},"PeriodicalIF":3.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146163173","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}
