RPM1 — Verticillium dahliae

Summary

VDAG_03095, also known as VdRPM1 or VdCYT-4, encodes a mitochondrial protein with RNase II and 3'-5' exoribonuclease activity, containing OB_CYT4_C, SH3_CYT4, and RNase_II/R domains. The gene is associated with mitochondrial mRNA 3'-end processing, mRNA breakdown, and RNA binding, as well as defense response, systemic acquired resistance, and signal transduction. It is linked to cell wall polysaccharide metabolic processes, including xyloglucan and polysaccharide metabolism, and phenylpropanoid and lignin anabolism. The protein localizes to mitochondria, the mitochondrial lumen, and P bodies. Related genes in other species are linked to drought tolerance and heterosis, though these associations are not established for V. dahliae.
