A BAC library of the SP80-3280 sugarcane variety (saccharum sp.) and its inferred microsynteny with the sorghum genome.

ABSTRACT:

Background

Sugarcane breeding has significantly progressed in the last 30 years, but achieving additional yield gains has been difficult because of the constraints imposed by the complex ploidy of this crop. Sugarcane cultivars are interspecific hybrids between Saccharum officinarum and Saccharum spontaneum. S. officinarum is an octoploid with 2n = 80 chromosomes while S. spontaneum has 2n = 40 to 128 chromosomes and ploidy varying from 5 to 16. The hybrid genome is composed of 70-80% S. officinaram and 5-20% S. spontaneum chromosomes and a small proportion of recombinants. Sequencing the genome of this complex crop may help identify useful genes, either per se or through comparative genomics using closely related grasses. The construction and sequencing of a bacterial artificial c
