Abstract

AtSWEET11 and AtSWEET12 are central players in phloem loading and long-distance sucrose translocation. During drought stress, these transporters enhance sucrose transport from shoot to root, increasing root proliferation. Chen et al. have now unravelled novel aspects of sucrose transport regulation, occurring via AtSWEET11 and AtSWEET12 phosphorylation and oligomerisation.

摘要

AtSWEET11 和 AtSWEET12 是韧皮部装载和长距离蔗糖转运的核心参与者。在干旱胁迫下，这些转运蛋白增强了从地上部到根部的蔗糖运输，增加了根的增殖。Chen 等人现在揭示了通过 AtSWEET11 和 AtSWEET12 的磷酸化和寡聚化调节蔗糖转运的新方面。
