Genome-wide identification of the peanut PITP gene family and functional verification of AhSFH8 in resistance to Aspergillus flavus infection.

ABSTRACT: Phosphatidylinositol transfer proteins (PITPs) are essential in eukaryotes for transporting phosphatidylinositol and phosphatidylcholine monomers across intracellular membranes, and they play key roles in regulating plant growth, signal transduction, stress responses, and other vital biological processes. Arachis hypogaea L., the crop most susceptible to Aspergillus flavus, has not been reported its PITP genes in responses to A. flavus infection. In this study, we performed a genome-wide identification of the PITP gene family in the peanut cultivar Tifrunner using the latest reference genome, and analyzed their expression patterns in different peanut tissues and at various time points after A. flavus inoculation. Furthermore, we cloned a candidate gene, AhSFH8 (a member of the PITP family'
