VIRESCENT-ALBINO LEAF 1 regulates leaf colour development and cell division in rice

VIRESCENT-ALBINO LEAF 1 regulates leaf colour development and cell division in rice

The de novo synthesis of purine nucleotides is crucial to all living organisms, but limited information is available for plants. In this study, we isolated a virescent-albino leaf 1 (val1) mutant of rice (Oryza sativa) that produces dynamic green-revertible albino and narrow-leaf phenotypes. In albi...

520 |a The de novo synthesis of purine nucleotides is crucial to all living organisms, but limited information is available for plants. In this study, we isolated a virescent-albino leaf 1 (val1) mutant of rice (Oryza sativa) that produces dynamic green-revertible albino and narrow-leaf phenotypes. In albino leaves, chloroplast development was defective, pigment contents were reduced, and cell division was impaired compared with the wild-type. Map-based cloning revealed that VAL1 encodes a phosphoribosylamine-glycine ligase (PurD), the second enzyme in the de novo purine biosynthesis pathway. Subcellular localization analysis demonstrated that VAL1 was localized in the chloroplast. Our results demonstrate that VAL1 is a crucial enzyme in the de novo purine biosynthesis pathway and is involved in regulating chloroplast development, chlorophyll metabolism, and cell division during leaf development in rice
