Popis: OVATE family proteins (OFPs) are the plant-specific transcription factors, and have significant functions in regulating plant growth, development and resistance. The OFP genes have been investigated in several plants, but they still lack a systematic analysis of OFP genes in Chinese pear and some other five Rosaceae genomes. Here, 28 PbrOFPs were identified within Chinese pear and compared them with those of other five Rosaceae genomes. Evolutionary tree revealed that all OFP genes from six Rosaceae genomes were divided into eight groups. Seventeen conserved microsynteny regions were detected in Chinese pear genome, suggested that these PbrOFP genes might be considered to have originated from the large-scale duplication events., indicating these PbrOFP genes might contain specialized regulatory mechanisms in these tissues, such as flower, ovary and fruit. Remarkably, two PbrOFP genes (Pbr010426.1 and Pbr010427.1) were up-regulated under Venturia nashicola treatment, and five PbrOFP genes were up-regulated under PEG treatment, suggesting that these genes might play crucial roles in defence to environmental stresses. Our data presented a systematic analysis and might aid in the selection of appropriate PbrOFPs for further functional studies in Chinese pear, especially in response to the mechanism of biotic and abiotic stresses.
