description | As the key transcription factors regulating auxin responsive genes expression, auxin response factors (ARFs) play critical roles in diverse aspects of plant growth and development. <i>Betula pendula</i> is a valuable ornamental tree, and the information on <i>ARF</i> gene family of <i>B. pendula</i> is needed for better understanding. The publication of the genome sequence of <i>B. pendula</i> enable to analyze the bioinformatics information and expression pattern of <i>BpeARF</i> gene family on the genome-wide basis. In this study, physical and chemical properties, chromosome location, phylogenetic relationship, gene structure, conserved domain, motif composition, and <i>cis</i>-acting element of <i>BpeARF</i> gene family were analyzed, and expression patterns of <i>BpeARF</i> genes were investigated using completely random design in different tissues and under exogenous NAA and drought treatments. A total of 17 <i>BpeARF</i> genes was identified from <i>B. pendula</i> genome, which were unevenly distributed on 13 chromosomes and encoded adequate proteins ranging from 613 to 1135 amino acids in length. Three <i>BpeARF</i> gene pairs were formed by segmental duplication, and the Ka/Ks values of these <i>BpeARF</i> gene pairs were less than 1. According to the phylogenetic relationship among <i>B. pendula</i>, <i>Betula platyphylla</i>, <i>Populus trichocarpa</i>, and <i>Arabidopsis thaliana</i>, the <i>BpeARF</i> genes were divided into four classes, and the intron/exon structure, conserved domain, and motif composition showed high similarity among the <i>BpeARF</i> genes within the same class. The <i>cis</i>-acting elements in the promoter regions of <i>BpeARF</i> genes were related to tissue development, hormone response, and stress resistance. Quantitative real-time PCR exhibited diverse expression patterns of <i>BpeARF</i> genes in different tissues and in response to exogenous auxin treatment and drought stress. The expressions of one, ten, seven, and three <i>BpeARF</i> genes were the high levels in buds, young leaves, stems, and roots, respectively. Under exogenous NAA treatment, six <i>BpeARF</i> genes in stems and roots were upregulated expression at all timepoints. Under drought stress, <i>BpeARF7</i> and <i>BpeARF15</i> were upregulated in stems and roots, and <i>BpeARF5</i> and <i>BpeARF6</i> were downregulated in leaves, stems, and roots. Our results provided valuable information for the classification and putative functions of <i>BpeARF</i> gene family, which may be helpful for selecting candidate genes and verifying gene function in the genetic engineering of birch trees in further research. |
