Despite their differences, these organs share common gene regulatory mechanisms with lateral root development. By comparing their mechanisms of hormonal regulation, we illuminate the shared genetic underpinnings and how plants repurpose vegetative development pathways in response to biotic stimuli. This adaptive retooling positions plants along the symbiotic spectrum from exploited hosts to mutualistic partners and strategic predators. Comparative analysis of the hormonal mechanisms that drive symbiotic organogenesis highlights the plasticity of developmental processes and the interplay between internal signalling and external environmental cues.</p>","PeriodicalId":23264,"journal":{"name":"Trends in Plant Science","volume":" ","pages":""},"PeriodicalIF":17.3,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144337038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since 2020, the betalain-based RUBY reporter has been used to visually track various cellular processes.

While root-derived carbon stabilization in aggregates and minerals is known, the role of slowly decomposing root fragments has been largely overlooked. We propose a new paradigm, 'iterative effects', integrating multigenerational root production and turnover with multistage root decomposition to address the build-up of moderately stable soil carbon forms. To inspire future studies, we develop several heuristic scenarios that differentiate root iterative effects on carbon cycling within branching root systems, across steady-state and non-steady-state ecosystems, under natural and anthropogenic disturbances, and shaped by intra- and intergenerational interactions among root processes. This theoretical framework provides novel insights into soil carbon cycling and ecosystem responses to global changes.</p>","PeriodicalId":23264,"journal":{"name":"Trends in Plant Science","volume":" ","pages":""},"PeriodicalIF":17.3,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144337040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
