Comprehensive Analysis of Evolutionary, Characterization and Expression for Sugar Transporter Family Genes in Nelumbo nucifera 

Abstract

BackgroundThe sugar transporter , an important class of transporter for sugars function, play regulators of many processes associated with growth, maturation and senescence processes in plant.ResultsIn this study, a total of 35NNUSTs were identified in the Nelumbo nucifera genome. Furthermore, all NNUSTs genes identified were grouped according to conserved domains and phylogenetic analysis. Additionally, we identified 316 ST genes in other10 representative plants, and performed a comparative analysis with Nelumbo nucifera, including evolutionary trajectory, gene duplication, and expression pattern. A large-scale analysis across plants and alga suggested that the ST family could have been originated from STP and Glct, expanding to form STP and SFP by dispersed duplication. Finally, quantitative real-time polymerase chain reaction and cis-elements analysis showed that the NNUSTs were response to abiotic stresses. ConclusionsThis provides useful resources when exploring the molecular evolution and mechanisms of NNUSTs in plants.
