      abstract = {Based on isobaric tags for relative and absolute  quantification (iTRAQ) technology, the proteome of grains  of a maize cultivar Huangzao 4 under drought stress at  grain filling stage was analyzed. The results show that  under drought stress, 438 proteins were differentially  expressed in the maize grains during grain filling. Among  them, 200 were up-regulated and 238 were down-regulated.  The gene ontology (GO) analysis shows that the biological  processes in which differential proteins are more involved  are cellular processes, metabolic processes and single  biological processes; proteins in the cell component  category are mainly distributed in cells, cell parts and  organelles; and the proteins the molecular function  category mainly possess catalytic activity and binding  function. Differentially expressed proteins classified by  COG are mainly involved in protein post-translational  modification and transport, molecular chaperones, general  functional genes, translation, ribosomal structure,  biosynthesis, energy production and transformation,  carbohydrate transport and metabolism, amino acid transport  and metabolism, etc. The subcellular structure of the  differentially expressed proteins is mainly located in the  cell chloroplast and cytosol. The proportions are 35.01%  and 30.21% respectively. KEGG metabolic pathway enrichment  analysis shows that the differentially expressed proteins  are mostly involved in antibiotic biosynthesis, microbial  metabolism in different environments, and endoplasmic  reticulum protein processing; the metabolic pathways with  higher enrichment are the carbon fixation pathway and  estrogen signaling pathway of prokaryotes; and the higher  enrichment and greater significance are in the  tricarboxylic acid cycle, carbon fixation of photosynthetic  organisms and proteasome. The results of this study  preliminarily reveal the adaptive mechanism of maize grains  in response to drought stress during grain filling,  providing a theoretical reference for maize  drought-resistant molecular breeding.},
