Abstract excerpt

Plants must coordinate chloroplast biogenesis with environmental conditions during seedling establishment, as failure to do so results in impaired phototrophic growth. Despite the biological importance of this early developmental stage, the influence of environmental factors on chloroplast biogenesis remains poorly understood. Here, we reveal a crucial role for GENOMES UNCOUPLED1 (GUN1)-mediated biogenic...
