MeJA-responsive MYB41-MYC2 cascade integrates glucomannan biosynthesis and DoTIP1–1 activation during salinity tolerance in Dendrobium officinale
A MeJA-responsive DoMYB41-DoMYC2 cascade that iteratively activates DoTIP1–1 expression and promotes the biosynthesis of GMs, thereby enhancing salinity tolerance in D. officinale is uncovered and provides genetic targets for salinity tolerance in breeding programs for this horticultural orchid.
