摘要：

Context The presence of cadmium (Cd) in rice fields poses a significant threat to both rice production and human health. The low-Cd hybrid rice variety Zhenliangyou 8612 (L-Cd ZLY8612), developed through the mutation of the OsNRAMP5 gene, exhibits significantly lower Cd uptake. However, the impacts of this mutation on nitrogen (N) uptake, photosynthetic efficiency, and grain yield remain unclear. The presence of cadmium (Cd) in rice fields poses a significant threat to both rice production and human health. The low-Cd hybrid rice variety Zhenli...
