Özet

ATP sulfurylase (ATPS, EC: 2.7.7.4) is a crucial enzyme for sulfate assimilation pathway in both plastids and cytosol in plants. In this study, genome-wide and comparative analyses of ATPSs in 11 higher plant species, including sequence and structural analyses have been performed. Expression of ATPS genes in sorghum under cadmium (Cd) and salinity (NaCl) stresses were also investigated to provide a model experimental data for the regulation of ATPS genes under stress conditions. Thirty-one ATPS genes from 11 plant species were found. It showed that ATPSs from different species have high sequence divergences, which cause structural differences among them. Phylogenetic analysis has shown that there are two major types of ATPSs evolved in dicots while monocots were evolved to have one type of ATPs. Finally, expression analysis of ATPS genes revealed tissue and stress dependent expression pattern, which indicates expressions of ATPS genes are tightly regulated.
