Chloroplast proteins involved in drought stress response in selected cultivars of common bean (Phaseolus vulgaris L.).

ABSTRACT: One of the major cell organelles, whose functions are affected during drought stress are chloroplasts. In this study, chloroplast proteome under drought was studied in two cultivars of common bean (Phaseolus vulgaris L), Tiber and more sensitive to drought, Starozagorski čern, which were subjected to drought for 6 and 13 days. A comparative proteomic analysis with 2D-DIGE was performed on the isolated chloroplast proteins from leaves. Together, 44 proteins with changed abundance between control and stressed plants were identified with LC-MS/MS from both cultivars. The majority of the identified proteins were involved in photosynthetic processes. The results showed a decrease in abundance in different structure components of photosystem I and II, and ATP synthase, which may indicate
