Figure 1From: Functional phosphoproteomic profiling of phosphorylation sites in membrane fractions of salt-stressed Arabidopsis thaliana MS/MS profile of phosphorylated peptides of PIP2;4. A, MS/MS spectra of PIP2;4 singly phosphorylation site (ALGSFGpSFGSFR); B, MS/MS spectra of PIP2;4 singly phosphorylation site (ALGSFSFGpSFR); C, MS/MS spectra of PIP2;4 doubly phosphorylation sites (ALGSFGpSFGpSFR).Back to article page
