DPB4 — Verticillium dahliae

Summary

VDAG_08781, designated VdDPB4 (also known as DPB4, VdCCAAT002, or CCAAT002), encodes an uncharacterized protein in Verticillium dahliae on chromosome DS572716. Related genes in other species belong to the DNA polymerase epsilon subunit family and contain a CBFA/NFYB domain and a histone-fold domain. VdDPB4 is associated with chromatin modeling, DNA repair, and response to AOS, all of which are biological process annotations observed in this species. The gene has been connected to vascular wilt disease in cotton (Gossypium hirsutum) and Arabidopsis thaliana. Studies of related genes in other Verticillium and Fusarium species further associate the family with fungal pathogenicity, though these findings are not established for VdDPB4 itself.
