Study on the Phenomenon and Genetic Basis of Segregation Distortion of Mating-type Factors in Lentinula Edodes;

首次系统地证实,在香菇中无论是菌丝原生质体单核体还是孢子单核体,也无论是野生菌株还是栽培菌株,交配型因子分离与理论预期相偏离都是一种在统计学具有普遍意义的现象。

Both α mating factor(with EAEA space) and its pre peptide are much better than α mating factor without EAEA spacer as secretive signal for the expression of ONC in P.

结果:糖基化ONC表观相对分子质量为(14～16)×103,且其糖基化不均匀,非糖基化蛋白肽链的相对分子质量约为12×103;采用不含EAEA结构的α交配因子作为分泌信号时ONC没有表达,利用含EAEA结构的α交配因子和α交配因子的pre肽作为分泌信号时均能够显著提高其表达量。
