Cloning and Bioinformatics Analysis of SmTIR1 Gene of Salvia miltiorrhiza

Auxin receptor plays a pivotal role in plant growth as regulated by auxin in plants. The growth of Salvia miltiorrhiza directly correlates with its quality. Nevertheless, to date gene of auxin receptor in S. miltiorrhiza is still unclear. In the present study, a gene with 1887 bp cDNA sequences was cloned in S. miltiorrhiza , and also performed bioinformatic analysis. This gene deploys the typical structure of auxin receptor TIR1 , thus being named SmTIR1 here. By predicating its functions, SmTIR1 is a hydrophilic protein with the typical structure of TIR1. Those results lay a foundation for further study of auxin receptor in S. miltiorrhiza , and provides theories for plant growth and development of S. miltiorrhiza as well.
