鉴别花脸香蘑原生质体单核体交配型的方法及其专用引物对SR-4×2
摘要：
本发明公开了鉴别花脸香蘑原生质体单核体交配型的方法及其专用引物对SR-4×2。该方法包括：分别以待鉴别的两株花脸香蘑原生质体单核体的基因组DNA为模板，用由SEQ ID No.1和SEQ ID No.2所示的两条单链DNA组成的PCR引物对进行PCR扩增，检测所得到的PCR产物的大小，如果所述待鉴别的两株花脸香蘑原生质体单核体的PCR产物均含有或均不含有500bp-800bp的DNA片段，所述待鉴别的两株花脸香蘑原生质体单核体的交配型相同；如果其中的一株含有500bp-800bp的DNA片段，另一株不含有500bp-800bp的DNA片段，所述待鉴别的两株花脸香蘑原生质体单核体的交配型不同。
摘要（英）：

The invention discloses a method for identifying the protoplast monokaryon mating types of lepista sordida and a special primer pair SR-4*2 thereof. The method comprises the following steps of: with genome DNAs (deoxyribonucleic acids) of the protoplast monokaryons of two plants of lepista sordida to be identified as templates, performing PCR (Polymerase Chain Reaction) amplification by using a PCR primer pair composed of two single chain DNAs as shown in SEQ ID No.1 and SEQ ID No.2, and detecting the sizes of the obtained PCR products; if the PCR products of the protoplast monokaryons of the two plants of lepista sordida to be identified both contain or do not obtain 500 bp-800 bp of DNA segments, indicating that the mating types of the protoplast monokaryons of the two plants of lepista sordida are the same; and if one plant contains 500 bp-800 bp of DNA segments, while the other plant contains no 500 bp-800 bp of DNA segments, indicating that the mating types of the protoplast monokaryons of the two plants of lepista sordida are different.
