Abstract excerpt
Strong UVB radiation critically restricts plant growth, yield, and distribution, while mechanisms enabling adaptation to intense UVB remain unclear. Here, we uncover that the F-box ubiquitin E3 ligase UVBT1 (also known as ETP2) is indispensable for UVB tolerance in A. thaliana. In the high-altitude Tibet accession, a distinctive 166-bp deletion in ETP2 promoter leads to the complete absence of the W-box element,...
