PCR-based gene marker with a high efficiency genome scanning (HEGS) system: application for distinguishing among cultivars in Lentinula edodes.

To establish a high throughput and cost-efficiency procedure for distinguishing among cultivars in Lentinula edodes, the polymorphism in the genes reported previously in this fungus was examined using PCR or PCR-RFLP techniques with a high-efficiency genome scanning (HEGS) system. As a result, PCR-based markers derived from eight genes (tyr, cap, ppa, IGS-RFLP, pri B-RFLP, mfbC-RFLP, gla-RFLP, xy-RFLP) showed polymorphisms among cultivars in this fungus and consequently, enabled to distinguish seventy-nine cultivars used in this study.
