Abstract
Salt stress is a major abiotic stress limiting the productivity and the geographical distribution of many plant species. Arabidopsis thaliana is an excellent model with rich genetic resources for modern plant biology research. To comprehensively and representatively understand salt-response mechanisms in A. thaliana, we applied the first attempt to use the most data (252 of 10,469 reviewed A. thaliana protein) from public protein database for displaying the enriched protein domains, Kyoto Encyclopedia of Genes and Genomes pathways, molecular functions, and cell localizations involved in salt-response. The data were analyzed by Database for Annotation Visualization and Integrated Discovery. Our results indicated salt-response proteins cross-talked not only with drought and temperature stress as previously reported but also with further stresses such as bacterium, light, metal ion, radiation, and wounding stress. Multiple cellular localizations under salt stress indicated proteins were versatile. In addition, 27 proteins have the characteristics with response to multiple stresses and localization in multiple places. We called it the ‘space-stress’ double cross-talk effects, which indicated that A. thaliana proteins dealt with salt stress and other stresses in a reciprocal economical way. An enriched bioinformatics analysis of the large data could provide clues and basis for the development of salt-response potential biomarkers for plant growth and crop productivity.
