A QTL for rice grain yield in aerobic environments with large effects in three genetic backgrounds por Venuprasad, R., Bool, M.E., Quiatchon, L., Atlin, G.N.

“…Apo and Vandana are drought-tolerant aerobic-adapted varieties, while Swarna and IR72 are important lowland rice varieties grown on millions of hectares in Asia but perform poorly in aerobic conditions. Two closely linked rice microsatellite (RM) markers, RM510 and RM19367, located on chromosome 6, were found to be associated with yield under aerobic soil conditions in all three backgrounds. …”

Human arsenic exposure risk via crop consumption and global trade from groundwater-irrigated areas por Alam, Mohammad Faiz, Villholth, Karen G., Podgorski, J.

“…Results show that RWM harvested area could increase by 54.1 million hectares (179% increase over current risk area), predominantly in South and Southeast Asia. This calls for the need to better understand the relative risk of arsenic exposure through food intake, considering the influence of growing trade and increased groundwater reliance for crop production.…”
