摘要： So far, over 50 spontaneous male sterile mutants of tomato have been described and most of them are categorized as genetic male sterility. To date, the mechanism of tomato genetic male sterility remained unclear. In this study, differential proteomic analysis is performed between genetic male sterile line (2-517), which carries the male sterility (ms10(35)) gene, and its wild-type (VF-11) using isobaric tags for relative and absolute quantification-based strategy. A total of 8272 proteins are quantified in the 2-517 and VF-11 lines at the floral bud and florescence stages. These proteins are involved in different cellular and metabolic processes, which express obvious functional tendencies toward the hydroxylation of the omega-carbon in fatty acids, the tricarboxylic acid cycle, the glycolytic, and pentose phosphate pathways. Based on the results, a protein network explaining the mechanisms of tomato genetic male sterility is proposed, finding the compromising fat acid metabolism may cause the male sterility. These results are confirmed by parallel reaction monitoring, quantitative Real-time PCR (qRT-PCR), and physiological assays. Taken together, these results provide new insights into the metabolic pathway of anther abortion induced by ms10(35) and offer useful clues to identify the crucial proteins involved in genetic male sterility in tomato.
