To identify and bioinformatically characterize the pentatricopeptide repeat (PPR) gene family within the tomato (Solanum lycopersicum) genome.
Screened annotated tomato protein sequences using Pfam PPR profile models to detect candidate PPR genes.
Analyzed motif architecture, phylogenetic relationships, chromosomal distribution, gene structure, subcellular localization signals, and Gene Ontology (GO) functional annotations.
Identified 471 putative PPR-encoding genes distributed across all 12 chromosomes, the majority of which lack introns.
Divided the family equally into P and PLS subfamilies, with the PLS subfamily further resolving into four phylogenetic clades: PLS, E, E+, and DYW.
Determined that most encoded PPR proteins contain targeting signals for mitochondria or chloroplasts and participate predominantly in RNA-related biological processes.
