【中文摘要】 利用 2 0個十堿基隨機引物 ,在基因組水平上對雙孢蘑菇 (Agaricusbisporus)的優(yōu)質低產型 (G型 )及低質高產型 (H型 )菌株進行了RAPD差異顯示 ,獲得一個與雙孢蘑菇子實體品質相關的大小約為 2 0 0 0bp的差異DNA片段 ,將其克隆 ,并應用點雜交及RFLP技術對其區(qū)分兩類菌株的有效性進行了檢驗。這為進一步建立特異性探針或PCR引物 ,從分子水平上提高雙孢蘑菇菌種性狀早期預測的準確性奠定了基礎

【英文摘要】 With 20 ten-mers random primers, the genomic differences between two types of Agaricus bisporus strain-good quality with low yield (G type) vs. poor quality with high yield (H type), were displayed by Random Amplified Polymorphic DNA (RAPD) technique. A 2000bp specific DNA fragment correlated to the quality of Agaricus bisporus fruitbody was obtained and cloned. Then dot hybridization and RFLP technique were used to determine the effectiveness of distinguishing two types of A. bisporus strains. And it was considered that our study had laid a foundation for further establishing a specific probe or PCR primer and for improving the accuracy of early predicting the characteristics of A. bisporus strains at molecular level.
