SWEET1‐mediated glucose transport is crucial for energy availability in Arabidopsis

open access: yesNew Phytologist, Volume 249, Issue 4, Page 1816-1830, February 2026.
Summary The stress‐responsive hormone abscisic acid (ABA) is known for its inhibitory effects on various physiological processes, including seed germination, often resulting in energy deprivation. Interestingly, ABA‐induced germination inhibition can be alleviated by exogenous glucose (Glc), mimicking a functional interplay between ABA and sugar ...
