  • Key message
    • Downregulation of TL by RNA interference (RNAi) and overexpression of OsMYB60 resulted in twisted leaf blades in transgenic rice
    • This suggests that TL may play a cis-regulatory role on OsMYB60 in leaf morphological development
    • We further discovered that a C2H2 transcription factor, OsZFP7, is an OsMYB60 binding partner and involved in leaf development
    • Quantitative reverse-transcription PCR showed that the loss-of-function of OsMYB60 led to downregulation of wax biosynthetic genes, leading to reduced amounts of total wax components on leaf surfaces under normal conditions
    • Taken together, these results demonstrate that OsMYB60 contributes to enhancing rice resilience to drought stress by promoting cuticular wax biosynthesis on leaf surfaces
    • Here, we show that the MYB transcription factor OsMYB60 positively regulates cuticular wax biosynthesis and this helps rice (Oryza sativa) plants tolerate drought stress
    • Mutation of OsMYB60 reduces rice resilience to drought stress by attenuating cuticular wax biosynthesis.
    • Compared with the wild type (japonica cultivar 'Dongjin'), osmyb60 null mutants (osmyb60-1 and osmyb60-2) exhibited increased drought sensitivity, with higher chlorophyll leaching and faster rates of water loss
