RPM1 — Magnaporthe oryzae 70-15

Summary

MGG_13800 (MoRPM1, also known as MoCYT-4) on chromosome 1 of Magnaporthe oryzae 70-15 encodes a mitochondrial protein with RNase II activity and 3'-5' exoribonuclease activity, belonging to the RNase_II/R and NA-bd_OB-fold families. This gene is associated with mitochondrial mRNA 3'-end processing, mRNA breakdown, programmed cell death, defense and immune responses, signal transduction, and homeostasis. It localizes to mitochondria, the mitochondrial lumen, and P bodies. MoRPM1 has also been linked to heterosis and drought tolerance. Studies of related genes in other species connect the family to similar exoribonuclease functions.
