Abstract Leaf-color mutants play an important role in the study of chlorophyll metabolism, chloroplast development, and
photosynthesis system. In this study, the yellow leaf 1 (yl1) rice mutant was identified from the ethyl methane
sulfonate-treated mutant progeny of Lailong, a glutinous japonica rice landrace cultivated in Guizhou Province,
China. Results showed that yl1 exhibited yellow leaves with decreased chlorophyll content throughout the growth
period. Chloroplast development in the yl1 mutant was disrupted, and the grana lamellae was loosely packed and
disordered. RNA sequencing and real-time quantitative polymerase chain reaction (qRT-PCR) analysis revealed
that the chlorophyll synthesis-related genes OsCHLH, OsCHLM, OsCHLG, PORB,… More >
