Relative volume of protein spots corresponding to differentially expressed proteins.

<p>(A) Quantification of protein expression and (B) Image of protein spots on gels. The left panel shows protein expression on water-treated control plants and right panel shows protein expression on salt-treated plants at day 48. Proteins were identified by mass spectrometry as being (1) fructose 1,6-bisphosphatealdolase; (2) glyceraldehyde-3-phostate dehydrogenase; (3) germin-like protein (4) HSP70. Bars show the mean values of replicate spots.
