Genome-wide association study and BSR-seq identify nitrate reductase-related genes in rice landraces (Oryza sativa L.).

ABSTRACT: Nitrogen (N) is an essential nutrient for rice (Oryza sativa L.) growth and development. However, the lower nitrogen use efficiency (NUE) results in an N fertilizer surplus, which causes many environmental problems. In this study, genome-wide association studies were used to detect nitrate reductase (NR)-related loci in 419 rice landraces. Using the general linear model (GLM), mixed linear model (MLM), linear model (LM), and linear mixed model (LMM), we found six, nine, seven, and six significant single-nucleotide polymorphisms (SNPs) associated (p < 1 × 10^-5) for three traits. Moreover, 98 significant SNPs were associated (logarithm of odds ≥ 3) with three traits through 3 V multi-locus random-SNP-effect mixed linear model. Interestingly, we found that Chr1_15896481 was signifi
