Genome-Wide Analysis of Auxin Receptor Family Genes in var. .

Transport inhibitor response 1/auxin signaling f-box proteins TIR1/AFBs) play important roles in the process of plant growth and development as auxin receptors. To date, no information has been available about the characteristics of the gene family in var. . In this study, 18 genes were identified and could be clustered into six groups. The genes are located in 11 of 18 chromosomes in the genome of var. , and similar gene structures are found for each of those genes. Several -elements related to plant response to phytohormones, biotic stresses, and abiotic stresses are found in the promoter of genes. The results of qPCR analysis show that most genes have differential patterns of expression among six tissues, with the expression levels of some of the genes repressed by salt stress treatment. Some of the genes are also responsive to pathogen b treatment. This study provides valuable information for further studies as to the role of genes in the regulation of plant growth, development, and response to abiotic stress.
