由于假松口蘑与松口蘑外观与口感相似,常被混入松口蘑中销售,严重影响松口蘑品质。本研究基于SRAP分子标记从300对引物组合中筛选出1对假松口蘑具有特异性的引物,并将这对引物的扩增产物进行克隆、测序以及重新设计引物,成功构建了假松口蘑的SCAR特异性分子标记(502 bp)。通过进一步验证,该SCAR标记只在假松口蘑个体中出现,表明所建立的SCAR标记可在分子水平上快速、准确地鉴定出假松口蘑。
由于假鬆口蘑與鬆口蘑外觀與口感相似,常被混入鬆口蘑中銷售,嚴重影響鬆口蘑品質。本研究基于SRAP分子標記從300對引物組閤中篩選齣1對假鬆口蘑具有特異性的引物,併將這對引物的擴增產物進行剋隆、測序以及重新設計引物,成功構建瞭假鬆口蘑的SCAR特異性分子標記(502 bp)。通過進一步驗證,該SCAR標記隻在假鬆口蘑箇體中齣現,錶明所建立的SCAR標記可在分子水平上快速、準確地鑒定齣假鬆口蘑。

Quality of Tricholoma matsutake has been seriously influenced because it is often mixed with T. baka-matsutake due to their similar appearance and taste. In this study, a pair of primers specific for T. bakamatsutake was screened from 300 pairs based on sequence-related amplified polymorphism ( SRAP) molecular markers. Then a SCAR marker (502 bp) for T. bakamatsutake was successfully developed by cloning, sequencing and primers redesigning. The SCAR marker was only presented in the individuals of T. bakamatsutake. In conclusion, the SCAR marker could quickly and accurately identify T. bakamatsutake at molecular level.
