This is especially true for organic farming, which relies on locally adapted species and varieties. Recently, participatory research approaches have emerged as effective means to support this endeavour. In this study, we collaborated with several stakeholders in the Lyon region, France, to evaluate three minor species related to common wheat (Triticum aestivum subsp. aestivum): einkorn (Triticum monococcum subsp. monococcum), emmer (Triticum turgidum subsp. dicoccum) and spelt (Triticum aestivum subsp. spelta (L.) Thell). First, we assessed the agronomic characteristics of each species, highlighting a distinction of einkorn that was associated with high tillering, high protein content, a long phenological cycle, small kernels and low relative yields. Second, we compared intra-species variabilities, revealing greater variation in emmer and spelt. Lastly, outcomes of the participatory approach, including testing adaptive methods and fostering collective learning, may interest other participatory research groups.","PeriodicalId":101358,"journal":{"name":"Quantitative plant biology","volume":"6 ","pages":"e21"},"PeriodicalIF":0.0,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12277212/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144683981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biophysical models have captured the general trend of fruit growth but often overlook the regulatory role of phytohormones. This study integrates a biophysical framework with the quantitative response of endogenous abscisic acid (ABA) in fruit. ABA dynamics are incorporated as a ripening signal, influencing sugar uptake, respiration, hydraulic conductance and transpiration processes. The model has been primarily tested on blueberries, a fruit with well-characterised ABA responses. Simulations show predictive accuracy and explanatory capability for fruit mass under variable climatic conditions. Notably, the model effectively simulates the impacts of environmental stresses such as heat, cold and drought, capturing the resulting physiological delays in fruit growth. Our research underscores the potential of integrating phytohormonal responses into biophysical models, providing key insights into fruit growth dynamics and practical guidance for optimising crop management under increasing climate uncertainties.","PeriodicalId":101358,"journal":{"name":"Quantitative plant biology","volume":"6 ","pages":"e19"},"PeriodicalIF":0.0,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12277213/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144683979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Primary shoots bend in response to gravity and then adjust the orientation through an organ-straightening process to achieve a mechanically favorable shape. However, how plants integrate branch structure with the shoot architecture remains uncertain. Here, we examined the lateral branch morphology of Arabidopsis thaliana mutants for myosin XI motor proteins through a combination of three-dimensional reconstruction and temporal imaging. The wild type and myosin xif mutant formed S-shaped branches and gradually adjusted the branch angle upwards. The myosin xik mutant exhibited straighter and drooping branches and maintained branch angles. The myosin xif xik double mutant formed branches with irregular directional changes with fluctuating angles. These results suggest that MYOSIN XIk and XIf are required for the establishment of branch morphology through upward bending, stabilizing growth direction, and maintaining curvature.","PeriodicalId":101358,"journal":{"name":"Quantitative plant biology","volume":"6 ","pages":"e15"},"PeriodicalIF":0.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12186554/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144487615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
