MTN3 — Brassica oleracea

Summary

BoMTN3, also known as BoSWEET11 and BoSWEET12, encodes a SWEET family protein with sucrose permease activity and sugar transmembrane transporter activity. Located in the membrane and plasmalemma, it is associated with carbohydrate and sucrose transport, protein homooligomerization, and processes including seed maturation, anther dehiscence, pollen and flower development, and embryo development. The gene has been associated with stem elongation, sugar transport and accumulation, carbon allocation, nitrogen remobilization and use efficiency, root growth under salt stress, vascular cell wall composition, plant growth, salicylic acid-mediated defense, disease resistance and susceptibility, root apical meristem activity, assimilate translocation, sucrose unloading from phloem, and seed development. Related genes in other species link the family to phloem loading, carbon export to roots, seed filling, and reduced embryo size with wrinkled seeds.
