ABSTRACT
The main goal of this chapter is to present and discuss the mechanisms of evolution that have contributed to development of the present state of overall architecture of Brassica genomes, with special emphasis on those belonging to oilseed Brassicas. Particular attention is paid to the processes that have formed genome size, chromosome number, cytogenetic landmarks, segmental structure, repetitive elements, gene/segment duplication, gene loss and sequence divergence in the course of evolution.
