Beyond degradation: COP1 fine-tunes plant growth through non-destructive protein tagging
Plant Science Research WeeklyIn the dark (e.g., under soil), hypocotyls elongate, but when exposed to light, they stop elongation. The biosynthesis of the plant hormone auxin is implicated in the elongation of hypocotyls in the dark. In the light, however, auxin action is inhibited, thereby limiting hypocotyl elongation. The E3…
