Sugarcane Genome Sequencing

Sugarcane cultivars derive from a recent interspecific hybrid obtained by crossing Saccharum officinarum and Saccharum spontaneum and represent relevant feedstock used worldwide for biofuel production.

The challenge in a sugarcane sequencing project is the size (10 Gb) and complexity of its genome structure that is highly polyploid and aneuploid with a complete set of homo(eo)logous genes predicted to range from 8 to 10 copies (alleles). Although sugarcane's monoploid genome is about 1 Gb, its highly polymorphic nature represent another significant challenge for obtaining a genuine assembled monoploid genome.
