摘要
Cuticular wax is synthesized from intracellular lipids that are exported by epidermal cells, and plant lipid transfer proteins (LTPs) play an important role in this process. The glycosylphosphatidylinositol (GPI)-anchored LTPs (LTPGs) are a large subgroup within the LTP family and function in lipid transport and wax formation. Although LTPG family members have been identified in several plant species, the LTPG gene family of apple (Malus domestica) remains uncharacterized. In this paper, we identified 26 potential LTPG genes by searching apple whole-genome annotation files using “GPI-anchored” and “lipid transferase” as keywords. Twenty of the 26 putative LTPG genes were confirmed as MdLTPG family members based on their subcellular localization predictions. The MdLTPGs were divided into four classes based on phylogenetic analysis and functional domain prediction. One member of each class was analyzed for subcellular localization, and all identified members were located on the plasma membrane. Most MdLTPG genes were induced by abiotic stress treatments such as low temperature, NaCl, and ABA. Finally, the MdLTPG17 protein was shown to interact with the lysine-rich arabinogalactan protein MdAGP18 to perform its function in wax transport during plant growth and development.
