摘要: RNA editing plays a key role in organelle gene expression. Little is known about how RNA editing factors influence soybean plant development. Here, we report the isolation and characterization of a soybeanyl(yellow leaf) mutant. Theylplants showed decreased chlorophyll accumulation, lower PS II activity, an impaired net photosynthesis rate, and an altered chloroplast ultrastructure. Fine mapping ofYLuncovered a point mutation inGlyma.20G187000, which encodes a chloroplast-localized protein homologous toArabidopsis thaliana(Arabidopsis) ORRM1.YLis mainly expressed in trifoliate leaves, and its deficiency affects the editing of multiple chloroplast RNA sites, leading to inferior photosynthesis in soybean. Taken together, these results demonstrate the importance of the soybean YL protein in chloroplast RNA editing and photosynthesis.
