Salt-induced root protein profile changes in seedlings of maize inbred lines with differing salt tolerances

Salt stress is one of the severest growth limited-factors to agriculture production. To gain in-depth knowledge of salt-stress response mechanisms, the proteomics analysis from two maize (Zea mays L.) inbred lines was carried out using two-dimensional gel electrophoresis (2-DGE) and matrix-assisted...
