Description
Fangqun OuYang and co-authors test how light rewrites spruce DNA tags in a 2026 study. DNA methylation, a chemical tag on genes, guides plant development, but its role in light response was murky. Seedlings of Norway spruce grew under two light levels, with or without far-red light added. Growth, genome-wide tags, and gene activity were all measured.
Light strength drove growth more than light color did. Both factors shifted the tag patterns, though in different chemical contexts across the genome. Gene activity changes followed strength more than tags did, and tag shifts mostly did not track activity shifts. One set of genes, for photosynthesis and daily rhythms, did move in step. The authors suggest tags may lock in a light memory for those genes.
