Comprehensive GWAS and Transcriptome Analysis Discovered Candidate Gene Associated with Starch Pasting Properties of Temperate japonica rice (Oryza sativa L.).

ABSTRACT: The growing market demand for high eating quality (EQ) rice, driven by improved living standards, highlights the need to better understand its complex genetic architecture. Starch pasting properties are critical determinants of rice EQ, yet their genetic basis remains incompletely understood. This study aimed to unravel the genetic factors underlying starch pasting properties in temperate japonica rice panel of 284 accessions comprising landraces and improved varieties. Genome-wide association studies conducted for two years identified 59 significant lead SNPs. Among them, consistent lead SNPs on chromosomes 2 and 8, in addition to the well-characterized Wx gene on chromosome 6 were detected from multiple traits and years. LD block analysis and transcriptome analysis of accessions with ext
