【中文摘要】 以傳統(tǒng)的形態(tài) ,生理生化分析和最新的DCS -PDMA性親和性測(cè)定方法為基礎(chǔ) ,結(jié)合群體分離分析和RAPD技術(shù)對(duì)來源于同一雙孢蘑菇異核體菌株的 12個(gè)不育同核原生質(zhì)體個(gè)體進(jìn)行分析 ,篩選與性親和性相關(guān)的分子標(biāo)記。研究結(jié)果表明 ,供試的 12個(gè)不育同核原生質(zhì)體個(gè)體被分成兩大類性親和性類型 ,其中一類 (A+ )包括不育同核原生質(zhì)體個(gè)體B、C、D、E、F、G、H、I、J、L ,另一類 (A-)則僅僅包括不育同核原生質(zhì)體個(gè)體K和M ,同時(shí)篩選到一個(gè)與性親和性相關(guān)的分子標(biāo)記OPA16 150 0 。從而為間接地利用雙孢蘑菇本身特有的交配型作標(biāo)記來指導(dǎo)雜交育種工作和進(jìn)一步將其性親和性基因定位分離克隆奠定了堅(jiān)實(shí)的基礎(chǔ)。

【英文摘要】 sterile homokaryotic protoplast isolates from the same heterokaryotic strain of Agaricus bisporus were analyzed in this paper. A molecular marker OPA16 1500 related to sexual compatibility was found using bulk segregation analysis and RAPD technology combined with the newest DCS-PDMA method and the traditional analysis of the morphological, physiological and biochemical characteristics of Agaricus bisporus. The results indicated that 12 sterile homokarytic protoplast isolates tested could be divided into two groups:group A + included B, C, D, E, F, G, H, I, J, L; group A - was made of K and M. Therefore, a solid foundation was established for Agaricus bisporus breeding through indirectly using its mating-type as marker for further location, isolation and cloning of its sexual compatibility gene.
