چکیده انگلیسی
Soil salinity and alkalinity are common constraints to crop productivity in low rainfall regions of the world. However, the physiological difference of plant response to these two stresses was short of deep investigation. This study has identified a set of differentially expressed proteins of tomato root exploring to NaCl and NaHCO3 stress by iTRAQ (isobaric tags for relative and absolute quantitation) assay. A total of 313 proteins responsive to NaCl and NaHCO3 were observed. Among these proteins, 70 and 114 proteins were up-regulated by salt and alkali stress, respectively. While down-regulated proteins were 80 in salt treatment and 83 in alkali treatment. Only 39 up-regulated proteins and 30 down-regulated proteins were shared by salt and alkali stresses. The majority of the down-regulated proteins accounted for metabolism and energy conversion, and the up-regulated proteins were involved in signaling or transport. Compared with salt stress, alkali stress down-regulated proteins related with the respiratory metabolism, fatty acid oxidative metabolism and nitrogenous metabolism of tomato roots, and up-regulated protein with the reactive oxygen species (ROS) scavenging and ion transport. This study provides a novel insight into tomato roots response to salt and alkali stress at a large translation level.
