摘要

•R1 type MYB TF, OsMYB-R1, is upregulated during Chromium(VI) and PEG stress.•OsMYB-R1 expressing lines are tolerant of chromium toxicity and drought stress.•Stress tolerance is due to improved lateral roots and strong antioxidant system.•Wound inducible OsMYB-R1 gene showed tolerance against fungal infection.•OsMYB–R1 mediated auxin-salicylic acid cross-talk enhances the defense response.
