Comments Information

    • Function

    • Plant non-specific lipid-transfer proteins transfer phospholipids as well as galactolipids across membranes. May play a role in wax or cutin deposition in the cell walls of expanding epidermal cells and certain secretory tissues.

    • Tissue specificity

    • Highly expressed in leaves and coleoptiles. No expression in roots.

    • Induction

    • By NaCl, abscisic acid and inoculation with the fungal pathogen E. graminis.

    • PTM

    • Contains four disulfide bonds 4-52; 14-29; 30-72; 50-86.
