Abstract excerpt

The genetic basis of long-term photoprotection under sustained high-light exposure in perennial trees remains poorly understood. Here, we report that a miniature inverted-repeat transposable element (MITE) located 1.2 kb upstream of PsiGCN2 reduces promoter activity by approximately 26% (P < 0.01) in transient heterologous reporter assays, consistent with a potential cis-regulatory contribution in Populus...
