MTN3 — Brassica oleracea

Summary

BoMTN3, also known as BoSWEET11 and BoSWEET12, is a cabbage gene on chromosome 3 that encodes a SWEET family protein with sucrose permease activity and sugar transmembrane transporter activity. It is associated with carbohydrate and sucrose transport, protein homooligomerization, and membrane localization at the plasmalemma and extracellular region. The gene has been connected to seed maturation, embryo development ending in seed dormancy, anther dehiscence, pollen and flower development, and stem elongation. Associations also include sugar transport, carbon allocation, nitrogen remobilization and use efficiency, root growth under salt stress, vascular cell wall composition, salicylic acid-mediated defense, disease resistance and susceptibility, assimilate translocation, 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.
