AhGLK1 affects chlorophyll biosynthesis and photosynthesis in peanut leaves during recovery from drought.

ABSTRACT: Peanut is an important edible oil crop plant whose quality and yield are greatly affected by drought. The process and molecular mechanisms of recovery from drought are also critical to its productivity, but are currently poorly characterized. Here, we investigate the involvement of peanut AhGLK1 in recovery from drought, and in particular its relationship with AhPORA, which encodes a key enzyme in chlorophyll biosynthesis. We found that chlorophyll content, chlorophyll fluorescence, AhPORA protein level and genes related to chlorophyll biosynthesis and photosynthesis declined markedly under drought conditions, but all increased during recovery. Consistent with this, AhGLK1 expression decreased during water stress and increased when the stress was removed. When AhGLK1 was transformed into A
