Functional Characterization of Selected Universal Stress Protein from Salvia miltiorrhiza (SmUSP) in Escherichia coli.

ABSTRACT: The multigene universal stress protein (USP) family is evolutionarily conserved. Members play indispensable roles in plant tolerance to abiotic stresses. Although relatively well-characterized in model plants, such as Arabidopsis thaliana and Oryzasativa, this family has not been investigated in Salvia miltiorrhiza, an important herbal plant for which yields can be limited by various abiotic stresses. Here, we identified 32 USP family members in the S. miltiorrhiza genome, and used phylogenetic analysis to sort these SmUSPs into four groups. Groups A and B belong to the ATP-binding class whereas Groups C and D are in the non-ATP-binding class. Motif analysis and multiple sequence alignment hinted that members of group A and B were able to bind ATP. Our qRT-PCR data fro
