Interpretive Summary:

Technical Abstract: An understanding of the structures and characteristics of the chloroplast, mitochondrial, and nuclear genomes have played significant roles in the genetic improvement of Allium crops. In this chapter I reflect upon the practical use of this genomic information for genetic improvement of the Alliums. The chloroplast DNA has been widely used for phylogenetic analyses among Alliums and related genera. Both the chloroplast and mitochondrial DNAs have been used as a source of polymorphic markers to classify male-sterile versus male-fertile cytoplasms. The nuclear genomes of the Alliums are among the largest in the plant kingdom. Such large genomes do not negatively affect the genetic improvement of the crops, but make sequencing and cloning more difficult.
