Complete sequencing of large and complex genomes of many crop plants such as wheat and other cereals provide a daunting challenge to the genomics community. We have devised a simple and elegant method of developing a high-resolution radiation hybrid physical map of the 4.2 Gb hexaploid wheat D-genome. This transformative technology allows the construction of a fine marker scaffold that bridges the resolution gap between meiotic and BAC-based physical mapping.This approach can easily be applied to most plant species that lack substantial genomics resources, similar to its wide use in majority of the animal genome projects.

ABOUT US

The main goal of the project is to construct and utilize high-resolution genome-wide RH-based physical maps of the wheat D-genome chromosomes that integrate the existing BAC-based contigs to facilitate the construction of sequence-ready physical maps. This research also will provide an unprecedented view into the evolution of cereal genomes. Importantly, the methodology developed in this project can easily be applied to other crop species even those with large and complex genomes. More...
