Proteomic analysis of soybean leaf under waterlogging stress at early vegetative stage

Waterlogging (WL), a major environmental stress, is a severe constraint on crop growth and productivity in many regions and situations. Waterlogging can reduce the photosynthesis rate, induce oxidative stress, accelerate leaf senescence, inhibit plant growth and finally lead to crop yield loss. Though traditional breeding programs and biotechnological methods have been used to improve plant tolerance to waterlogging, few practical results have been obtained so far. Soybean is sensitive to various abiotic stresses, particularly waterlogging stress during the germination, early vegetative, and early reproductive stages. Proteomic analysis has been widely used to understand the function of differentially regulated proteins under abiotic stress, which is crucial for investigating the mechanisms of plant in response to stress. Several proteomic studies have examined the changes in the root system of soybean under waterlogging stress, revealing multiple pathways involved in stress perception and signal transduction.
