摘要:

【目的】利用原生质体单核化技术获得具有优良性状的阿魏菇(Pleurotus ferulae)新菌种,为新疆野生阿魏菇新品种的保育及产业化应用提供技术支撑。【方法】采用原生质体制备技术获得阿魏菇单核菌株并进行交配型测定。【结果】酶解3.5 h时,PL01、PL163与 PL176等3株野生阿魏菇亲本菌株的原生质体释放量最大,浓度最高达20.6×105个/ mL,通过优化的原生质体单核化技术最终获得50个单核菌株,亲本菌株PL163、PL01、PL176原生质体单核化率分别为 25.68%、12.8%、10.8%,获得率较低。对其进行了交配型测定,每株亲本菌株得到2种交配型的单核菌株。其中,菌株PL01与PL163、 2种交配型获得比例均为1∶3,而PL1762种交配型获得比例为1∶4。每个亲本菌株与获得的单核菌株在菌丝长速、菌落形态方面均具有差异。以不同交配型的单核菌株PL01-P16、PL01-P49、PL163-7、PL163-24 、PL176-23、PL176-39作为杂交育种材料进行配对,获得12株性状优良的杂交菌株。拮抗反应表明,12株杂交菌株与亲本之间形成明显隆起的拮抗带,与亲本菌株显著不同。【结论】3株阿魏菇野生菌株在原生质体再生单核获得率、长速、形态等方面具有丰富的多样性,获得的杂交菌株为新疆阿魏菇新品种的保护奠定了基础,并为选育优良阿魏菇杂交品种提供了良好的种质材料。

Abstract:

【Objective】 To obtain a new strain of Pleurotus ferulae with excellent traits by the protoplast monokaryotation technology in the hope of laying the theoretical and technical foundation for the selection and industrial production of new varieties of wild P. ferulae in Xinjiang. 【Method】 The protoplasmic preparation technique was used to obtain the mononuclear strain of P. ferulae and determine its mating type. 【Result】 At 3.5 h after enzymolysis, the protoplast release of the 3 wild P. ferulaeparent strains PL01, PL163 and PL176 was the maximum, with the concentration as high as 20.6 × 105 /mL. Through optimized protoplast monokaryonization, 50 mononuclear strains were finally obtained from the 3 parent strains. The protoplast monokaryonization rates of parent strains PL163, PL01 and PL176 were 25.68%, 12.8% and 10.8%, respectively, with a low acquisition rate. Then, the mating type was determined, and mononuclear strains with 2 mating types were obtained from each parent strain. Among them, the acquisition ratio of the 2 mating types from PL01 and PL163 strains was 1∶3, while that of PL176 was 1∶4. Differences were found in mycelial growth rate and colony morphology among each parent strain and the obtained mononuclear strains. Subsequently, pairing was performed using mononuclear strains PL01-P16, PL001-P49, PL163-7, PL163-24, PL176-23 and PL176-39 with different mating types as hybrid breeding materials, and 12 hybrid strains with excellent traits were obtained. The antagonistic reaction showed that the 12 hybrid strains formed an obvious uplifted antagonistic band between their parents, and were significantly different from their parents. 【Conclusion】 The 3 wild P. ferulae strains present rich diversity in protoplast regeneration, mononuclear acquisition rate, growth rate and morphology. The obtained hybrid strains lay a foundation for the conservation of new varieties of P.
