摘要：

Reducing cadmium (Cd) levels in rice grains through genetic improvement is an effective strategy for rice production in Cd-contaminated soils. In this study, we developed transgenic rice lines from Zhongzao39, featuring targeted expression of OsHMA3 driven by the OsYSL16 promoter. We conducted a comparative analysis to evaluate the phenotypic and physiological responses of transgenic rice lines versus wild-type (WT) plants under Cd treatment. Under 0.1, 1, and 10 μM Cd treatment conditions, transgenic rice plants exhibited a reduction of ove...
