Abstract:
A proteomic approach was applied in the study on the changes in proteins that occur during seed development in soybean [Glycine max(L.)Merr.] cv N2899.Protein expression at different developmental stages(15，20，30，40，50 DAF and mature seed)were compared using PDQuest software(Bio-Rad)after two-dimensional gel electrophoresis.About 337 low-salt extractable protein spots were resolved in gels.It was found that some proteins were present throughout the whole developmental stages，while others were associated with early seed filling or seed maturation.Among total spots 18 of 30 highly differentially expressed proteins were identified by MALDI-TOF-MS，querying peptide mass fingerprinting data in NCBInr database by Profound(http://www.prowl.rockefeller.edu).It was found that these identified proteins are mainly involved in seed maturation(e.g.conglycinin)，stress tolerance(e.g.ascorbate peroxidase)，cell division(e.g.Skp1)，and proteins transportation(e.g.calreticulin).These results indicate that the seed development process is complex，and the identified genes would provide a basis for molecular elucidation of the temporal effects on protein accumulation in soybean seed.
