Identification and Evolution of Salt-Tolerant Genes in Weedy Rice Through High-Throughput Resequencing.

ABSTRACT: Weedy rice, a wild relative of cultivated rice, is highly stress-resistant and proliferates in paddy fields. In this study, 353 weedy rice accessions were analyzed to identify salt-tolerance genes using population evolution analysis, phenotypic screening, genome-wide association studies (GWAS), transcriptome analysis, haplotype characterization, gene knockout experiments, and Na⁺ and K⁺ ion flux assays. Population structure analysis classified the accessions into six distinct groups. Three salt-tolerant accessions-HW131, HW136, and HW119-were identified based on leaf rolling degree (LRD), leaf withering degree (LWD), chlorophyll content (ChlC), and nitrogen content (NC) traits. GWAS and transcriptome data pinpointed LOC_Os06g39270 and LOC_Os06g11860 as c
