The invention discloses a paddy rice leaf color regulation and control gene YL1 and a use thereof. The paddy rice leaf color regulation and control gene YL1 has a gene nucleotide sequence shown in the formula of SEQ ID NO. 1. A coded protein sequence is shown in the formula of SEQ ID NO. 2. Through a map-based cloning technology, the novel paddy rice leaf color regulation and control gene YL1 is obtained. Through a transgenosis function complementation experiment, functions of the gene are verified. The YL1 and a chloroplast ATPase protein complex subunit AtpB produce synergism and YL1 gene mutation causes chloroplast ATPase activity reduction so that a photosynthesis-associated protein expression level is reduced, chloroplast development is influenced, chlorophyll content is reduced and a yellow leaf phenotype is produced. The protein and coding gene can further elucidate a paddy rice leaf color regulation and control molecule mechanism, can be used for crop genetic improvement and has an important meaning f
