LTP12 — Brassica oleracea var. botrytis

Summary

BoLTP12, located on cauliflower chromosome 8, encodes a protein with the Plant_nsLTP, Bifunc_inhib/LTP/seed_store, and Bifun_inhib/LTP/seed_sf domains. The gene is associated with lipid binding, lipid transport, proline transport, microsporogenesis, pollen development, and defence response to fungi. It has been linked to proline content and pollen fertility traits. The encoded protein localises to the plant-type cell wall and extracellular space. Studies of related genes in other species connect the family to cytoplasmic male sterility and heterosis, though these associations are not yet established in cauliflower.
