Vitamin E Function in Stress Sensing and Signaling in Plants

Abstract

Vitamin E is involved in heat stress acclimation. In this issue of Developmental Cell, Fang et al. (2018) uncover a new link between Vitamin E and plant retrograde signaling and show that vitamin E is required for the accumulation of 3'-phosphoadenosine 5'-phosphate, an inhibitor of exoribonucleases, to protect microRNAs from degradation.
