摘要:

本研究旨在筛选生长速度变快的珍珠菇新品种,实验以内蒙古阿尔山野生珍珠菇为试材,采用酶解法制备珍珠菇原生质体,并利用高压电晕电场对原生质体诱变处理,在PDA培养基上用涂布法培养原生质体,以期得到优质突变菌株。实验结果表明,当电压为6 kV,处理时间10 s~10 min条件下珍珠菇原生质体诱变致死率为30.51%~100%;当电压为7 kV,处理时间10 s~5 min条件下诱变致死率为39.55%~100%,且诱变原生质体再生菌株日均生长速度均高于对照组。以电压为6 kV为例,经10 s诱变的原生质体再生菌株生长速度较对照提高119%。定量分析漆酶活性,发现在6 kV、3 min诱变条件下的原生质体再生菌株第6天漆酶活性较对照组提高了8.79倍。表明高压电晕电场放电诱变野生珍珠菇原生质体,可以提高菌株的生长速度和质量,提高漆酶活力,得到正突变菌株,为野生珍珠菇的进一步驯化提供了新的方向。

Abstract:

The purpose of this study is to screen new varieties of Pholiota nameko with rapid growth rate. Pholiota nameko protoplasts were prepared by enzymatic hydrolysis using wild Pholiota nameko from Alshan of Inner Mongolia as materials, and the protoplasts were mutated by high-voltage corona electric field. The protoplasts were cultured by coating method on PDA medium in order to obtain high quality mutant strains. The experimental results show that under the conditions of voltage of 6kv and processing time of 10 s-10 min, the Pholiota nameko protoplasts mutagenesis mortality rate is 30.51%-100%; When the voltage is 7 kV and the treatment time is 10 s-5 min, the mutagenesis mortality rate is 39.55%-100%, and the daily growth rate of regenerated strains from mutagenic protoplasts is higher than that of the control group. Taking a voltage of 6 kV as an example, the growth rate of protoplast regenerated strains mutagenized by 10 s are 119% higher than the control group. Quantitative analysis of laccase activity revealed that the laccase activity of protoplast regenerated strains under 6 kV and 3 min mutation conditions increased by 8.79 times compared to the control group on the 6th day, which indicates that high-voltage corona discharge mutagenesis of wild Pholiota nameko protoplasts can improve the growth rate and quality of the strain, enhance laccase activity, and obtain positive mutant strains, providing a new direction for further domestication of wild Pholiota nameko.

Key words: Pholiota nameko, protoplast, high-voltage corona electric field, growth rate, laccase
