Comparative genomic and structural phylogenetics indicate a stepwise assembly of the phosphorelay, where receptor domains diversified alongside lineage-specific shifts in cytokinin usage, from cis-zeatin-enriched systems in early-diverging lineages toward trans-zeatin-dominant signaling in vascular plants, while downstream executors remained evolutionarily constrained. Cross-lineage transcriptomic comparisons under heat stress suggest a rewiring of physiological outputs. Although growth repression is deeply conserved, broader metabolic responses differ across clades: trehalose-associated osmoprotection in early land plants, whereas angiosperms transitioned to redox- and transport-based strategies.

We challenge this dichotomy by proposing a codriven framework where N cycling emerges from tight plant-microbe coregulation. While microorganisms execute biochemical machinery for transformations, plants actively steer the rate, location, and pathways of these processes through strategic carbon allocation, chemical signaling, and root trait deployment. We argue that plants dynamically balance 'Outsourcing' strategies that stimulate microbial N mobilization with 'Do-It-Yourself' foraging to synchronize N supply with plant demand. Reframing the N cycle as a coregulated system shifts theory from reaction-based to control-based, providing a mechanistic foundation to integrate plant traits into next-generation biogeochemical models, improving N use efficiency and reducing environmental risks.</p>","PeriodicalId":23264,"journal":{"name":"Trends in Plant Science","volume":" ","pages":""},"PeriodicalIF":20.8,"publicationDate":"2026-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148228415","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}

Philosophy, as a way of life, can promote plant awareness by re-examining how humans perceive and value plant life. I propose four complementary modes of perception, based on hierarchy, similarity, relation, and otherness, each revealing how cultural assumptions shape human attention and ethical attitudes toward plants. Drawing on phenomenology, Indigenous worldviews, Eastern thought, ecofeminism, everyday aesthetics, and vegetal ontology traditions, I integrate philosophical thought with the emerging construct of plant awareness. Practicing seeing plants differently through philosophy can retrain human perception toward them and nurture humility, gratitude, and responsibility. Such reflection on the plant-human bond reinforces the dialogue between science, education, and the humanities, and strengthens the ethical foundations of sustainability.</p>","PeriodicalId":23264,"journal":{"name":"Trends in Plant Science","volume":" ","pages":""},"PeriodicalIF":20.8,"publicationDate":"2026-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148219891","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}

We argue that it should always be stated explicitly on which organ the chemotype specification is based on, because chemical profiles can differ among organs.
