High throughput isolation of microsatellites in hop (Humulus lupulus L.)

Procedures to generate usable microsatellite marker sequences should be optimized for cost-effectiveness in each species. For hop, we have used a cocktail of several restriction enzymes to digest the genomic DNA. This is followed by capture of microsatellite-containing sequences with long microsatellite probes attached to a membrane. The enrichment level for GA and GT libraries was 37% and 35%, respectively, and 100% of the clones contained microsatellite sequences. Libraries can be generated from genomic DNA in approximately 10 d.
