Genome-wide analysis of the AP2/ERF family genes in Salix suchowensis

Abstract:

In order to study the members and classification of the AP2/ERF transcription factor family of Salix suchowensis, and to further explore its function in the growth and development, the AP2/ERF family genes were identified, classified, chromosomed, and their physical and chemical properties, gene structure, conserved domains, and expression patterns were also analyzed using bioinformatics techniques and methods. The results showed that Salix suchowensis contains 178 AP2/ERF genes, which were classified into four subfamilies: AP2, ERF, RAV, and Soloist according to the evolutionary relationship between the AP2/ERF conserved domain and the AP2/ERF genes of Arabidopsis thaliana. In addition, the results of tissue expression pattern analysis showed that the AP2/ERF family genes had obvious tissue specificity, it was strongly expressed in leaf, root, shoot, and flower, and weakly expressed in other tissues.
