A key player in glutamate export from Arabidopsis chloroplasts

The et al. identified a chloroplast glutamate exporter in Arabidopsis thaliana. The Plant Cell (2023). By Samantha The and Mechthild Tegeder, School of Biological Sciences, Washington State University, Pullman, WA, 99164, USA https://doi.org/10.1093/plcell/koad310 Background: Plants produce amino acids in chloroplasts, and membrane transporters are needed to move these amino acids to the cytosol. In the […]
