PTI5 — Solanum lycopersicum

Summary

SOLYC02G077370.1, designated PTI5 (SlPTI5, Pti5) on tomato chromosome 2, encodes a protein with an AP2/ERF domain and sequence-specific DNA binding and transcription cis-regulatory region binding activities. The protein localises to the nucleus. PTI5 is associated with resistance to bacterial disease, aphids, and Botrytis cinerea, and has been connected to pathogen defense responses, gray mold resistance, and disease tolerance. The gene is also linked to fruit ripening traits, carotenoid and chlorophyll content, and a broad range of biological processes including salicylic acid metabolism, phytoalexin biosynthesis, jasmonic acid anabolism, regulation of ethylene-mediated signaling, cell wall modification, and autophagy. Related AP2/ERF domain-containing proteins in other species further support the family's involvement in stress and developmental responses.
