OsPRDA1 Interacts With OsFSD2 To Promote Chloroplast Development by Regulating Chloroplast Gene Expression in Rice.

ABSTRACT: Chloroplasts are vital for photosynthesis, and their development necessitates proper expression of chloroplast genes. However, the regulatory mechanisms underlying rice chloroplast gene expression have not been fully elucidated. In this study, we obtained an albino mutant of rice, white seedling and lethal 1 (wsl1), which displays significantly decreased chlorophyll contents and impaired chloroplast ultrastructure. The causal gene Oryza sativa PEP-RELATED DEVELOPMENT ARRESTED 1 (OsPRDA1) was isolated using Mutmap + and verified by gene editing and complementary assays. The expression of OsPRDA1 is induced by light, and OsPRDA1 is localized in chloroplasts. Transcription sequencing revealed that genes related to photosynthesis were differentially expressed in wsl1. The expression levels of
