Cytokinin drought
WebJul 2, 2024 · In plants, cytokinin signaling is mediated by a canonical two-component system (TCS), which comprises AHKs (histidine kinases), AHPs (histidine phosphotransfer proteins), and ARRs (Arabidopsis response regulators). Cytokinin signaling components have been shown to act as negative regulators of plant drought tolerance. WebNov 28, 2024 · Cytokinin is required for the defence against high light stress and to protect plants from a novel type of abiotic stress caused by an altered photoperiod. Additionally, cytokinin has a role in the response to temperature, drought, …
