SWEET1 — Phaseolus vulgaris

Summary

PHAVU_001G064300, designated PvSWEET1 on chromosome 1 of French bean (Phaseolus vulgaris), encodes a SWEET family protein with sugar transmembrane transporter activity. It also exhibits identical protein binding, protein homodimerization activity, and general protein binding. The gene is associated with carbohydrate transport, protein homooligomerization, S phase, and lateral root formation. Its product localizes to the ER membrane, ER, extracellular space, membrane, and plasmalemma. PvSWEET1 is linked to root length and sugar transport. Related genes in other species connect the family to nematode resistance and sucrose content.
