Recent reports have demonstrated that cytokinins (CKs) and strigolactones (SLs) act as negative and positive regulators, respectively, in plant drought responses. These reports have also suggested potential crosstalk between CK and SL signaling pathways in several mechanisms underlying plant drought acclimation. We discuss these reports with a view to potentially exploiting this crosstalk in the design of drought-tolerant crops.
Keywords: crosstalk; cytokinin; drought; strigolactone.
