Differential regulation of gene products in newly synthesized Brassica napus allotetraploids is not related to protein function nor subcellular localization.

ABSTRACT:

Background

Allopolyploidy is a preeminent process in plant evolution that results from the merger of distinct genomes in a common nucleus via inter-specific hybridization. Allopolyploid formation is usually related to genome-wide structural and functional changes though the underlying mechanisms operating during this "genomic shock" still remain poorly known. The aim of the present study was to investigate the modifications occurring at the proteomic level following an allopolyploidization event and to determine whether these changes are related to functional properties of the proteins. In a previous report, we applied comparative proteomics to synthetic amphiploids of Brassica napus and to its diploid progenitors B. rapa and B. oleracea. Although several hundred polypeptides displ
