Abstract:Colorful woody plants are highly valued for their ornamental qualities, and are commonly used in garden landscape design. We previously cultivated several ornamental poplar varieties from bud mutants of Populus sp. Linn. ‘2025’ (ZL2025), each with different leaf colors. Based on transcriptome data from these varieties with varying anthocyanin pigmentation, we identified and named an R2R3‐MYB gene, PdMYB113. The mRNA of PdMYB113 accumulated in the leaves of the red‐leaf mutants ‘QHY’ and ‘LHY’, but barely expre… Show more
