PDF1 — Brassica oleracea

Summary

BoPDF1, located on chromosome 4 of cabbage (Brassica oleracea), encodes a protein belonging to the protodermal factor 1 (PDF1) family, characterised by the Protodermal_1 and PDF1_C domains. This gene is associated with defence responses, including cell death, jasmonic acid and auxin signalling, and responses to egg deposition and oviposition. It is also linked to glucosinolate and indole glucosinolate anabolism, sulfation, and quorum sensing. The encoded protein localises to the extracellular region and nucleus. BoPDF1 is associated with photosynthetic rate and protodermal development, with L1 layer-specific expression observed. Studies of related genes in other species link the family to pathogen resistance, biotic and abiotic stress tolerance, zinc tolerance, seed dormancy, leaf shape, and transpiration rate.
