MTN3 — Brassica oleracea

Summary

BoMTN3 (BOLC102_C09P007620.1) on cabbage chromosome 9 encodes a SWEET family protein with sucrose permease activity and sugar transmembrane transporter activity. This gene is associated with carbohydrate and sucrose transport, protein homooligomerization, and membrane localization at the plasmalemma and extracellular regions. It has been linked to seed maturation, embryo development ending in seed dormancy, anther dehiscence, pollen development, and flower development. Associations also include stem elongation, sugar transport and accumulation, carbon allocation, nitrogen remobilization and use efficiency, root growth under salt stress, root apical meristem activity, salicylic acid-mediated defense response, disease resistance and susceptibility, assimilate translocation, sucrose unloading from phloem, seed development, and vascular cell wall composition. Related genes in other species are linked to phloem loading, carbon export to roots, seed filling, and reduced embryo size.
