“…Genes identified in this study were related to many aspects of plant cell metabolism, such as signal transduction, metabolism of amino acids, secondary metabolites, saccharides, and fatty acids. Mutation in these genes affects seed development and the embryogenesis process (Baud et al 2003;Lara et al 2003;Suda and Giorgini 2003;Schaller 2004;Saha et al 2007). The low number of repeated annotated genes represented by single ESTs identified in this work indicates an efficient normalization of the libraries, as only the PPR and SPA genes were represented by more than four ESTs.…”

“…PPR proteins have been implicated in many crucial functions including chloroplast biogenesis, embryogenesis fertility restoration in CMS plants, and plant development (Saha et al, 2007). An emerging theme of PPR protein function is regulation of various aspects of gene expression in plastids, including transcription, splicing, RNA cleavage, RNA editing, translation, and RNA stabilization (SchmitzLinneweber and Small, 2008).…”

“…Although mitochondrial functions are conserved among eukaryotes, genome structure and the regulatory mechanisms for gene expression in mitochondria are, surprisingly, quite divergent 3 . Plants are unique in that they possess extremely large mitochondrial genomes 4 and exhibit complex mechanisms for editing mitochondrial mRNA 5,6 involving a large family of pentatricopeptide repeat proteins 7,8 . Presumably due to their sessile lifestyle and/or the presence of plastids, regulation of mitochondrial gene expression appears to be quite important for plants.…”
