Abstract excerpt
Reduction of the level of arsenic (As) in rice grains is an important challenge for agriculture. A recent study reported that the OsABCC1 transporter prevents the accumulation of As in grains by sequestering As-phytochelatin complexes into vacuoles in the upper nodes. However, how phytochelatins are provided in response to As remains unclear. Here, we show that the phytochelatin synthase OsPCS1 plays a crucial...
