Özet
TEOSINTE-BRANCHED1/CYCLOIDEA/PCF (TCP) proteins are important regulators of growth and developmental processes including branching, floral organ morphogenesis and leaf growth as well as stress response. This study identified 27 TCP genes of Phaseolus vulgaris (common bean), which were divided into three clusters based on phylogenetic relationship. In addition, this study showed that some of TCP genes such as Pvul-TCP-4 and Pvul-TCP-15 located on chromosomes 3 and 7, Pvul-TCP-7 and Pvul-TCP-20 located on chromosome 7 and 9, were segmentally duplicated. On the other hand, a total of 20 Pvul-TCP genes have predicted to be targeted by microRNAs (miRNA). Most of the miRNA-target genes were Pvul-TCP-1,-11,-13 and -27, which were targeted by 13, 17, 22 and 13 plant miRNAs, respectively. miR319 was one of the highly represented regulatory miRNAs to target TCP transcripts. Promoter region analysis of TCP genes resulted that the GT-1 motif, which was related to salt stress, was found in 14 different Pvul-TCP genes. Expression profiling of 10 Pvul-TCP genes based on RNA-sequencing data further confirmed with quantitative real-time RT-PCR measurements identified that Pvul-TCP genes under salt stress are expressed in a cultivar- and tissue-specific manner.
