Capturing diversity in the cereals: many options but little promiscuity.
It is generally recognized by geneticists and plant breeders alike that there is a need to further improve the ability to capture and manipulate genetic diversity. The effective harnessing of diversity in traditional breeding programmes is limited and, therefore, it is vital that meiotic recombination can be manipulated given that it plays a pivotal role in generating diversity. With the advent of a wider range of genomics technologies, our understanding of meiotic processes should increase rapidly. Although comparative genetics has been useful, particularly in the broader grass family, the development of physical maps, long-range sequencing and transcript profiles promises to unravel the complexities of genomes as large or larger than wheat. Highlighting the most significant findings to date, this review pools the knowledge on these tools and reproductive processes.
