The yield of rice is mostly affected by three factors, namely, panicle number, grain number and grain weight. Variation in panicle and grain numbers is mainly caused by tiller and panicle branches generated from axillary meristems (AMs).MOC1encodes a putative GRAS family nuclear protein that regulates AM formation. Although several alleles ofMOC1have been identified, its variation in germplasm resources remains unclear. In the present study we characterized a novelmoc1allele namedgnp6which has a thymine insertion in the coding sequence of the SAW motif in the GRAS domain. This mutation causes arrested branch formation. The SAW motif is necessary for nuclear localization of GNP6/MOC1 where it functions as a transcription factor or co-regulator. Haplotype analysis showed that the coding region ofGNP6/MOC1was conserved without any non-synonymous mutations in 240 rice accessions. However, variation in the promoter region might affect the expression of it and its downstream genes. Joint haplotype analysis ofGNP6/MOC1andMOC3showed that haplotype combinations H9, H10 and H11, namelyMOC1-Hap1 in combination withMOC3-Hap3,MOC3-Hap4 orMOC3-Hap5 could be bred to promote branch formation. These findings will enrich the genetic resources available for rice breeders.
