Characterization of the Liriodendron chinense Pentatricopeptide Repeat (PPR) Gene Family and Its Role in Osmotic Stress Response.

ABSTRACT: The Pentatricopeptide repeat (PPR) superfamily is a large gene family in plants that regulates organelle RNA metabolism, which is important for plant growth and development. However, a genome-wide analysis of the PPR gene family and its response to abiotic stress has not been reported for the relict woody plant Liriodendron chinense. In this paper, we identified 650 PPR genes from the L. chinense genome. A phylogenetic analysis showed that the LcPPR genes could roughly be divided into the P and PLS subfamilies. We found that 598 LcPPR genes were widely distributed across 19 chromosomes. An intraspecies synteny analysis indicated that duplicated genes from segmental duplication contributed to the expansion of the LcPPR gene fami
