Enhanced Cd phytoextraction by rapeseed under future climate as a consequence of higher sensitivity of HMA genes and better photosynthetic performance

Abstract: This study aimed to investigate the underlying physiological, biochemical, and molecular mechanisms responsible for Brassica napu's potential to remediate Cd-contaminated soil under current (CC) vs. future (FC) climate (400 vs. 800 ppm of CO2, 21/14 degrees C vs. 25/18 degrees C). B. napus exhibited good tolerance to low Cd treatments (Cd-1, Cd-10, i.e., 1, 10 mg kg(-1)) under both climates without visible phytotoxicity symptoms. TI sharply decreased by 47 % and 68 % (p 0.05) and 61 (p < 0.05) years, respectively, compared to CC
