Foxtail millet (Setaria italica L. P. Beauv) has been considered as a tractable model crop in recent years due to its short growing cycle, lower amount of repetitive DNA, inbreeding nature, small diploid genome, and outstanding abiotic stress-tolerance characteristics. | Nội dung Text Comparative proteomic investigation of drought responses in foxtail millet .den color inherit .ttnd ol .ttnd ul .ttnd dl padding 0 0px 0 20px .ttnd hr margin 10px 0px .ttnd a href javascript void 0 .ttnd a href color inherit dtextscript p text-align left dtextscript img vertical-align middle Pan et al.

Beauv has been considered as a tractable model crop in recent years lt br gt due to its short growing cycle lower amount of repetitive DNA inbreeding nature small diploid genome and lt br gt outstanding abiotic stress-tolerance characteristics. With modern agriculture facing various adversities it s urgent to lt br gt dissect the mechanisms of how foxtail millet responds and adapts to drought and stress on the proteomic-level. lt br gt Results In this research a total of 2474 differentially expressed proteins were identified by quantitative proteomic lt br gt analysis after subjecting foxtail millet seedlings to drought conditions. 321 of these 2474 proteins exhibited significant lt br gt expression changes including 252 up-regulated proteins and 69 down-regulated proteins. The resulting proteins could lt br gt then be divided into different categories such as stress and defense responses photosynthesis carbon metabolism lt br gt ROS scavenging protein synthesis etc. according to Gene Ontology annotation. Proteins implicated in fatty acid and lt br gt amino acid metabolism polyamine biosynthesis hormone metabolism and cell wall modifications were also identified. lt br gt These obtained .
