Abstract excerpt

Arsenic contamination in paddy soils compromises rice yield, grain safety, and human health. Flooded conditions mobilize arsenic, which enters roots via silicon and phosphate transporters, causing spikelet sterility and straighthead disease. In this study, the emphasis is placed on differentiating tolerant and sensitive genotypes, where inclusion type genotypes are expected to display arsenic toxicity symptoms....
