LTP12 — Brassica oleracea var. botrytis

Summary

BoLTP12 (LTP12) on cauliflower chromosome 7 encodes a protein with a Plant_nsLTP domain and a bifunctional inhibitor/lipid-transfer/seed-storage domain. The gene is associated with lipid binding and IgE binding molecular functions, and is linked to proline transport, lipid transport, microsporogenesis, and pollen development. It localizes to the plant-type cell wall and extracellular region. Associations with proline content and pollen fertility have been noted. Studies of related genes in other species link the family to cytoplasmic male sterility and heterosis, though these are not established for this gene.
