preparation example Construction

[0032] The preparation method of the solid regeneration plate (RM): add sorbitol and agar to the liquid MCM medium so that the concentrations are 1M and 20g / L, respectively.

[0033] 1.2 Protoplast preparation

[0034] 1) Take the hyphae of A. japonica and culture them in liquid MCM medium at 160rpm and 25°C for 4 days (3-5 days are acceptable), filter and collect the mycelium with 3 layers of sterile lens paper, and then use 0.6M manna Alcohol aqueous solution washed 2-3 times.

[0035] 2) Suspend the hyphae (about 1 g) of A. japonica in step 1) in 1.5% lysozyme solution (dissolve 1.5 g lysozyme with 0.6M mannitol aqueous solution and set the volume to 100 mL; lysozyme was purchased from Guangdong Bide Biotechnology Co., Ltd., catalog number: Bd_8110001023), in a water-bath shaker (32°C, 60rpm) for 2 hours, filtered with 3 layers of sterile lens tissue and collected the filtrate.

[0036] 3) Centrifuge the filtrate of step 2) at 3000 rpm for 10 min and collect the precipita...

[0050] Example 1. Using the PCR primer pair IS-857c to identify the mating type of the protoplast monokaryon of the mushroom

[0051] 1. PCR reagents for identifying or assisting in identifying the mating type of monokaryon protoplasts

[0052] The reagents for identifying or assisting in identifying the mating type of the protoplast monokaryon of Amanita chinensis in this embodiment consist of PCR primer pair IS-857c, 10×Taq buffer, dNTP mix, Taq DNA polymerase and ddH 2 O composition.

[0053] Among them, the PCR primer pair IS-857c is composed of two single-stranded DNAs, IS-857c-F and IS-857c-R, and its sequence is as follows:

[0054] IS-857c-F:5'-TGAGATATAATCACGAGTGCAAAT-3' (SEQ ID No.1)

[0055] IS-857c-R: 5'-TAGGACAAAATGGTAGGGGA-3' (SEQ ID No. 2).

[0056] 10×Taq buffer, dNTP mix and Taq DNA polymerase were purchased from Beijing Shengxu Baichuan Company (CNS).

Abstract

The invention discloses a method for identifying the mating types of Lepista sordida protoplast monokaryons and a special primer pair IS-857c therefor. The method comprises the following steps: respectively taking genome DNAs (deoxyribonucleic acid) of two Lepista sordida protoplast monokaryons 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 both or neither of the PCR products of the two Lepista sordida protoplast monokaryons to be identified contains a DNA segment of 500-800bp, indicating that the mating types of the two Lepista sordida protoplast monokaryons to be identified are the same; and if one of the two contains a DNA segment of 500-800bp and the other does not contain a DNA segment of 500-800bp, indicating that the mating types of the two Lepista sordida protoplast monokaryons to be identified are different.

Description

technical field [0001] The invention relates to a method for identifying the monokaryon mating type of the protoplast and the special primer pair IS-857c thereof. Background technique [0002] The nutrient incompatibility system is a genetic system for identifying aliens. In most fungi, this system can cause genetically distinct individuals to produce characteristic somatic incompatibility in the junction zone (Qi Yuancheng et al., Chinese cultivated pellagra Comparison of somatic cell incompatibility test and RAPD analysis results of Pleurotus species. Acta Mycophyta Sinica, 2010, 29 (3)) reaction, the intensity of somatic cell incompatibility reaction varies from individual to individual. In fungi, nutritional incompatibility is also known as somatic incompatibility or heterokaryotic incompatibility. fusion to maintain individual genetic stability. The mating type is the type of combination determined according to whether the individuals of the mating factors can complet...
