Pentatricopeptide repeat (PPR) proteins, which are characterized by tandem 30–40 amino acid sequence motifs, constitute of a large gene family in plants. Some PPR proteins have been identified to play important roles in organellar RNA metabolism and organ development in  Arabidopsis  and rice. However, functions of  PPR  genes in woody species remain largely unknown. Here, we identified and characterized a total of 626  PPR  genes containing PPR motifs in the  Populus trichocarpa  genome. A comprehensive genome-wide analysis of the poplar  PPR  gene family was performed, including chromosomal location, phylogenetic relationships and gene duplication. Genome-wide transcriptomic analysis showed that 154 of the  PtrPPR  genes were induced by biotic and abiotic treatments, including  Marssonina brunnea , salicylic acid (SA), methyl jasmonate (MeJA), mechanical wounding, cold and salinity stress. Quantitative RT-PCR analysis further investigated the expression profiles of 11  PtrPPR  genes under different stresses. Our results contribute to a comprehensive understanding the roles of PPR proteins and provided an insight for improving the stress tolerance in poplar.
