| مستخلص: | Biochar is an effective and economical strategy for in situ soil cadmium (Cd) remediation. It is essential to comprehensively investigate how biochar mitigates Cd uptake of the main rice subspecies. A pot experiment was established via adding corn stalk biochar into Cd-contaminated soil growing indica Yangdao 6 (YD) and japonica Nangeng 9108 (9108). 9108 had lower shoot biomass (-17.9%) but higher root biomass (+14.4%) and shoot Cd concentration (+29.4%) than YD. Biochar decreased soil available Cd by 25.2% and shoot Cd concentration by 13.6% through the liming and passivation effects. Biochar also favored Cd mitigation by recruiting Fe reducer, Cd remover and plant growth-promoting rhizobacteria (e.g. Bacteroides, Deferrisomatota, Bacillus and Allorhizobium). Besides, biochar reduced Cd uptake by stimulating iron plaques formation for 9108. Moreover, biochar did not reduce Cd uptake by inhibiting Cd transporter genes' expressions and it increased OsHMA2 expression in YD. In conclusion, biochar had great capacity in mitigating Cd pollution and rice subspecies responded differently to biochar in iron plaque formation and Cd transporter genes. The research established a comprehensive understanding of the mechanisms underlying Cd mitigation by biochar and helped to breed low Cd-accumulated rice cultivars to safeguard rice production.
