NLP7-CRF-PIN, the nitrate-cytokinin-auxin crosstalk module, conveys root nitrate signals and regulates shoot growth adaptive responses (PNAS)
Plant Science Research WeeklyNitrate, the prominent form of nitrogen used by most land plants, is a signal regulating plant growth and development. Nitrate sensing by roots not only regulates root development to facilitate nutrient foraging, but also the growth of distant plant organs. Cytokinin is a mobile signal coordinating nitrate…
Cytokinin–CLAVATA cross-talk is an ancient mechanism regulating shoot meristem homeostasis in land plants (PNAS)
Plant Science Research WeeklyThe shoot apical meristem (SAM) maintains a small pool of pluripotent stem cells, which are the source of all above-ground plant tissues. In Arabidopsis thaliana, CLAVATA3 (CLV3), CLAVATA1(CLV1) and RECEPTOR-LIKE PROTEIN KINASE2 (RPK2) repress WUSCHEL (WUS) expression. WUS induces CLV3, forming a local…
