Genome-wide investigation and expression analyses of the pentatricopeptide repeat protein gene family in foxtail millet.

ABSTRACT:

Background

Pentatricopeptide repeat (PPR) proteins are encoded by a large gene family of approximately 450 members in Arabidopsis and 477 in rice, which characterized by tandem repetitions of a degenerate 35 amino acid characteristic sequence motifs. A large majority of the PPR genes in the higher plants are localized in organelles. Their functions remain as yet largely unknown. The majority of characterized PPR proteins have been found to function in modulating the expression plastid and mitochondrial genes in plants.

Results

Here, a genome-wide identification and comparison of the PPR genes from 5 organisms was performed, including the moss Physcomitrella patens, the lycophyte Selaginella moellendorffii, the eudicot Arabidopsis, and the monocots rice and foxtail millet. It
