Understanding the Role of PIN Auxin Carrier Genes under Biotic and Abiotic Stresses in Olea europaea L.

ABSTRACT: The PIN-FORMED (PIN) proteins represent the most important polar auxin transporters in plants. Here, we characterized the PIN gene family in two olive genotypes, the Olea europaea subsp. europaea var. sylvestris and the var. europaea (cv. 'Farga'). Twelve and 17 PIN genes were identified for vars. sylvestris and europaea, respectively, being distributed across 6 subfamilies. Genes encoding canonical OePINs consist of six exons, while genes encoding non-canonical OePINs are composed of five exons, with implications at protein specificities and functionality. A copia-LTR retrotransposon located in intron 4 of OePIN2b of var. europaea and the exaptation of partial sequences of that element as exons of the OePIN2b of
