Medicago sativa (Alfalfa) is an important agricultural plant for animal forage and nitrogen fixation, and has potential value in ligno-cellulosic energy production. In the quest to understand the plant, I generated a draft genome sequence of M. sativa via two reduced representation sequencing approaches: methylation-dependent filtration, and high CoT filtration. Libraries created from each approach were sequenced on an Illumina next-generation sequencing platform yielding approximately 2.5Gb of raw data. A combination of reference-based genome assembly approaches using the closely related species, Medicago truncatula as a reference, and de novo genome assembly approaches were performed to assemble the draft genome. The reference-based assembly generated 312,011 contigs with weighted median contig length (N50) of 247 bases, whereas de novo assembly produced 547,304 contigs with N50 of 275 bases. The creation of the M. sativa draft genome is vital for downstream functional analyses such as genome wide gene mining and gene expression profiling.
