title: SCAR makers and multiplex PCR-based rapid molecular typing of Lentinula edodes strains.
abstract: Lentinula edodes is the second most important cultivated mushroom worldwide, the most commercial strains have been identified only through traditional phenotypic analysis. In this study, a simple rapid PCR-based molecular method was developed for distinguishing commercial strains of L. edodes by developing specific sequence characterized amplified region (SCAR) markers and establishing multiplex PCR assays with the SCAR primers. Derived from the randomly amplified polymorphic DNA (RAPD) and sequence-related amplified polymorphism (SRAP) techniques, 10 informative SCAR markers were generated from 10 polymorphic RAPD and SRAP bands. The differences in SCAR phenotypes among different strains made these SCAR markers potentially useful to characterize 6 strains and identify them from other studied strains. Moreover, different SCAR phenotypes also made the other 17 studied strains to be divided into four distinguishable groups. The multiplex PCR assays were further established for the joint use of some SCAR markers efficiently. Compared with some identification methods reported previously, the special feature of this new molecular method is technically rapid and convenient in the practical use and suitable for analyzing large numbers of samples. Thus, the simple rapid PCR-based molecular method can be used as a helpful assistant tool for the lentinula industry. To our knowledge, this study is the first to describe a development of a new SCAR maker-based multiplex PCR assay for rapid molecular typing of edible mushroom.
