The Yin-Yang of Cytokinin Homeostasis and Drought Acclimation/Adaptation

Trends Plant Sci. 2016 Jul;21(7):548-550. doi: 10.1016/j.tplants.2016.05.006. Epub 2016 Jun 3.


Increasing evidence has shown that cytokinins (CKs) regulate plant drought acclimation/adaptation through a multistep phosphorelay pathway. Recent progress has allowed us to suggest a yin-and-yang-type relationship between CK homeostasis and acclimation/adaptation responses that modulates plant fitness and yields stability under drought through a complex network involving crosstalk with abscisic acid (ABA).

Keywords: abscisic acid; cytokinin; growth adjustment; plant drought adaptation; transcription factor; two-component system.
