OsHAK1 is a major transporter mediating the uptake of monovalent thallium ions in rice under potassium-deficient conditions.

Abstract excerpt

Thallium (Tl) is one of the most toxic elements to ecosystems, even at very low concentrations. Monovalent Tl ions (Tl+) can be readily taken up by plants, thereby entering the food chain and posing risks to humans. However, the molecular mechanisms governing the uptake of Tl+ by plants remain unclear. In the present study, we investigated the role of OsHAK1, a high-affinity potassium ion (K+) transporter, in Tl+...
