Navigating the genetic basis of cadmium accumulation: a comprehensive analysis of low-cadmium accumulation rice.

ABSTRACT: The presence of cadmium (Cd) in rice poses a significant health risk to consumers, highlighting the urgency of breeding rice varieties with low Cd accumulation. To identify genetic resources and potential genes for developing such rice varieties, a comprehensive genome-wide association study (GWAS) was conducted on 158 rice varieties, which tested between 2021 and 2023 in low cadmium accumulation testing framework, to identify candidate genes associated with cadmium content in brown rice. Based on their parental origin and genetic population structure analysis, we categorized these 158 varieties into four subgroups: Luohong, lcd1, intermediate and early indica series. Specifically, the four subgroups of low cadmium varieties were breeded based on OsNramp5 mutants Luohong 3A/4
