I. Phenotype for sesame samples under salt stress

Sample instruction: Sesame salty sensitive (SS) and tolerance (ST) samples, 5 time points (0, 2, 6, 12, 24 hours), three biological replicates.

II.  Expression analysis among different samples in sesame by iTRAQ

In this project, we employed iTRAQ [1] to calculate the expression quantification of sesame proteins among 10 samples, including 5 time points in sesame salty sensitive (SS) and tolerance (ST) samples respectively. After curation, 4,956 genes, representing 18.255% of all sesame proteins, were detected to express among 10 samples in sesame.

III. Protein-protein interaction analysis by STRING database

The STRING database aims to collect and integrate this information, by consolidating known and predicted protein–protein association data for a large number of organisms. The associations in STRING include direct (physical) interactions, as well as indirect (functional) interactions, as long as both are specific and biologically meaningful [2].

In this project, we used the information of protein-protein interaction from STRING database to detect the relationships of protein-protein interaction of different expression protein between different samples in sesame. And further to load resulting interactive data into Cytoscape software to achieve interactive network [3].
