Chickpea membrane proteome map. 2-DE was carried out using 100 μg membrane proteins and electrofocused using linear 13 cm IPG strips, pH 3–10 (A) and pH 4–7 (B). The second dimension was performed using 12.5% SDS-PAGE and protein spots were visualised using MS-compatible silver stain. The identified protein spots were marked by arrows and the numbers corresponding to the spot Id are listed in Table 1. The experiments were performed with at least two biological and three experimental replicates.
