SWEET1 — Phaseolus vulgaris

Summary

PHAVU_009G134300, designated PvSWEET1 on chromosome 9 of French bean (Phaseolus vulgaris), encodes a SWEET family protein with sugar transmembrane transporter activity, also capable of identical protein binding and homodimerization. The product localizes to the endoplasmic reticulum membrane, the plasma membrane, and the extracellular space. PvSWEET1 is associated with carbohydrate transport, protein homooligomerization, S phase, and lateral root formation. It has been linked to root length and sugar transport. Related genes in other species connect the family to nematode resistance and sucrose content.
