Whole-genome duplication is a significant evolutionary mechanism in plants, with polyploid plants often displaying larger organs and enhanced adaptability to unfavorable conditions compared their diploid counterparts. The cell wall acts as primary defense for plant cells against external stresses, playing an essential role the plant’s resistance various stressors. In this study, we utilized both autotetraploid its donor rice (Oryza sativa L.) analyze phenotypic differences comparatively, composition of key components, expression related genes under normal conditions, well stress from Magnaporthe oryzae (M. oryzae) salt. Our findings indicated that exhibits significantly characteristics than rice. At seedling stage, lignin, cellulose, hemicellulose, pectin levels were markedly lower Additionally, 24 associated major components showed differential between tetraploid filling lignin content higher rice, while cellulose hemicellulose notably lower.

Grain-related traits are pivotal in rice cultivation, influencing yield and consumer preference. The complex inheritance of these traits, involving multiple alleles contributing to their expression, poses challenges breeding. To address challenges, a multi-locus genome-wide association study (ML-GWAS) utilizing 35,286 high-quality single-nucleotide polymorphisms (SNPs) was conducted. Our utilized an panel comprising 483 genotypes sourced from northeast core set landraces collected various regions India. Forty quantitative trait nucleotides (QTNs) were identified, associated with four grain-related traits: grain length (GL), width (GW), aroma (Aro), length–width ratio (LWR). Notably, 16 QTNs simultaneously identified using two ML-GWAS methods, distributed across chromosomes. Nearly 258 genes found near the significant QTNs. Gene annotation revealed that sixty exhibited elevated expression levels specific tissues implicated pathways quality. ontology (GO), (TO), enrichment analysis pinpointed 60 candidate (CGs) enriched relevant GO terms. Among them, LOC_Os05g06470, LOC_Os06g06080, LOC_Os08g43470, LOC_Os03g53110 confirmed as key contributors GL, GW, Aro, LWR. Insights CGs illuminate regulation genetic connections, offering potential targets for future studies.
