    Abstract:
    Soybean-based intercropping is important for sustainable agricultural practice on a regional and global scale. However, most soybean varieties use shade avoidance strategy to acquire more light absorption when suffered in canopy shade in intercropping systems, thus reduced the yield of the whole population on a farmland. The mechanisms underlying early response of soybean in shade avoidance is still largely unknown. Here we report our identification of differentially accumulated proteins in shade-sensitive soybean seedlings by global quantitative proteome analysis under white light (WL) and shade conditions. By using Tandem Mass Tag (TMT) labelling and HPLC fractionation followed by high-resolution LC-MS/MS analysis, 29 proteins were found up-regulated and 412 proteins were found down-regulated in soybean seedlings by 2-h shade stress than that by 2-h WL treatment. Multiple differentially expressed proteins are enriched in carbohydrate metabolic process especially in the biosynthetic pathways of cell wall polysaccharides in soybean seedlings by shade stress comparing to those in WL growth conditions. Physiological assays showed that saccharides were rapidly declined in shoot apex of soybean seedlings under a short-term shading. Our results would provide new insights into the mechanisms of shade avoidance responses in soybean seedlings.
