Abstract excerpt

Sugar transport across membranes is critical for plant development and yield. However, an analysis of the role of intracellular sugar transporters in senescence is lacking. Here, we characterized the role of Senescence-Associated Sugar Transporter1 (SAST1) during senescence in Arabidopsis (Arabidopsis thaliana). SAST1 expression was induced in leaves during senescence and after the application of abscisic acid...
