Analysis of pummelo proteome using iTRAQ


ABSTRACT: For protein identification, the following parameters were used. Peptide mass tolerance = 20 ppm, Missed cleavage = 2, MS/MS tolerance = 0.1 Da, Enzyme = Trypsin, Fixed modification: Carbamidomethyl (C), iTRAQ8plex(K), iTRAQ8plex(N-term), Variable modification:Oxidation(M),Decoy database pattern=Reverse. The MASCOT search results for each SCX elution were further processed using the ProteomicsTools (version 3.1.6) which includes the programs BuildSummary, Isobaric Labeling Multiple File Distiller and Identified Protein iTRAQ Statistic Builder (Information can be accessed from Research Center for Proteome Analysis (http://www.proteomics.ac.cn/).

Comprehensive and quantitative proteomic information on citrus floral bud is significant for understanding male sterility of the cybrid pummelo (G1+HBP) with nuclear genome of HBP and foreign mitochondrial genome of G1. Scanning electron microscopy and transmission electron microscopy analyses of the anthers showed that the development of pollen wall in G1+HBP was severely defective with a lack of exine and sporopollenin formation. Proteomic analysis was used to identify the differentially expre  ...[more]
