Sugarcane Genome Project

Towards sequencing the polyploid genome of buy cheap generic levitra sugarcane

 

BIOEN researchers participate in the Sugarcane Genome Sequencing Initiative

Sugarcane cultivars derive from a recent interspecific hybrid obtained by crossing Saccharum officinarum and Saccharum spontaneum andrepresentrelevant 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 www.fotosamar.net about 1 Gb, its highly polymorphic nature represent another significant challenge for obtaining a genuine assembled monoploid genome.

The Saccharum complex is diverse in genome content and organization. Collectively, these species present tremendous allelic diversity which in addition to the closely related species, Sorghum, Miscanthus and Erianthus represents a significant reservoir of genetic variability that could be exploited.

The goal of the Sugarcane Genome Sequencing Initiative is to identify strategies for sugarcane genome sequencing in the light of new technologies, focusing on whole genome shotgun (WGS) and/or BAC insert sequencing (BAC) approaches. We recognized the needs of an integrated bioinformatic platform and issues regarding sugarcane gene and protein nomenclature are being considered.

Strategies

  • BAC end sequencing
  • R570 BAC selection and sequencing
  • Whole genome shot-gun sequencing (SP80-3280, Q165, LA Purple and no prescription SES 208)
  • ChIP-Seq
  • EST re-sequencing
  • High density genetic mapping
