Natural Variation In Osgasr7 Regulates Grain Length In Rice

Identification of quantitative trait loci (QTLs) for grain length (GL) is important to rice breeding for increasing grain yield and appearance quality. Recent studies have identified a number of QTLs/genes as key grain length regulators by linkage mapping or genome-wide association study (GWAS). These regulators are involved in G protein signaling, phytohormone signaling or transcriptional regulation, etc (Li et al., 2018).
