Arsenic (As) contamination in paddy soil can cause phytotoxicity and elevated As accumulation in rice grain. Rice varieties vary in As uptake and tolerance, but the underlying mechanisms remain unclear. In this study, the aus variety Kasalath was found to be more tolerant to arsenate [As(V)] than th...
