| Summary: | The regulation of vital plant activities by hormones is governed by a family of macromolecular peptides referred to as GH3 genes. This work analyzed the expression patterns of GH3 family genes in pear tissues using transcriptome data and bioinformatics analysis. In the Bai Li pear genome, a total of 18 <i>PbGH3</i> genes were identified. Comparative evolutionary studies have shown a strong association between PbGH3 and AtGH3 class I and class II proteins. The role of <i>PbGH3</i> genes in growth activities and hormone regulation was revealed using gene ontology (GO) and promoter region analysis. In addition, although certain <i>PbGH3</i> genes exhibited tissue-specific expression in sepals, the majority had a ubiquitous expression across all tissues. Bioinformatics and expression studies suggest that the GH3 gene family in pears may have a role in controlling the abscission of the fruit’s sepals. This work sheds light on the pear fruit sepal shedding process and may inspire further research. |
