Sugarcane genomics: depicting the complex genome of an important tropical crop.

In the past few years, approaches such as molecular cytogenetics and the use of molecular markers have permitted significant advances in the establishment of the evolutionary origin and genome structure of sugarcane, an important polyploid crop. The availability of new resources, such as a bacterial artificial chromosome library and a huge collection of expressed sequence tags, has opened the gateway to promising functional analyses on a genomic scale.
