1 PIF1 directly and indirectly regulates chlorophyll biosynthesis to optimize the greening process in Arabidopsis. Chlorophyll phytochrome interacting factor 3-like 5 Arabidopsis thaliana
2 PIF1 negatively regulates chlorophyll biosynthesis and seed germination in the dark, and light-induced degradation of PIF1 relieves this negative regulation to promote photomorphogenesis. Chlorophyll phytochrome interacting factor 3-like 5 Arabidopsis thaliana
3 Here, we report that PIF1 regulates expression of a discrete set of genes in the dark, including protochlorophyllide oxidoreductase (POR), ferrochelatase (FeChII), and heme oxygenase (HO3), which are involved in controlling the chlorophyll biosynthetic pathway. Chlorophyll phytochrome interacting factor 3-like 5 Arabidopsis thaliana
4 These data strongly suggest that PIF1 directly and indirectly regulates key genes involved in chlorophyll biosynthesis to optimize the greening process in Arabidopsis. Chlorophyll phytochrome interacting factor 3-like 5 Arabidopsis thaliana
