Mitochondrial Function and Maize Kernel Development Requires Dek2, a Pentatricopeptide Repeat Protein Involved in nad1 mRNA Splicing.

Genetics - 1 Jan 2017

Abstract excerpt

In flowering plants, many respiration-related proteins are encoded by the mitochondrial genome and the splicing of mitochondrion-encoded messenger RNA (mRNA) involves a complex collaboration with nuclear-encoded proteins. Pentatricopeptide repeat (PPR) proteins have been implicated in these RNA-protein interactions. Maize defective kernel 2 (dek2) is a classic mutant with small kernels and delayed development....
