PR1 — Verticillium dahliae

Summary

VDAG_07131, designated VdPR1 (also known as PRB1), on Verticillium dahliae chromosome DS572709, encodes a subtilisin-like serine-type endopeptidase belonging to the peptidase S8 family. The encoded protein exhibits serine-type peptidase and endopeptidase activity, with fibrinogen and IgE binding capabilities. VdPR1 is associated with induced systemic resistance, defense response, innate immunity, and immune response, as well as auxin transport, phenylpropanoid anabolism, cell wall organization, and rhythmic processes. It has been linked to chlorophyll content, drought tolerance, and salt tolerance traits. The protein localizes to the extracellular, fungal-type vacuole, Golgi complex, and late endosome lumen. Related genes in other species have been linked to apoplastic and cytoplasmic effector functions, though pathogenicity phenotypes in those relatives were reported as unaffected.
