| 摘 要： | 在先前的工作中,曾经运用简并PCR和染色体步行的方法从香菇中获得了1个信息素受体编码基因和1个信息素前体编码基因。根据香菇135菌株的原生质体单核体的全基因组测序信息,设计了4对引物,用于扩增香菇苏香菌株的原生质体单核体SUP2中的信息素受体编码基因STE-3的同源物及其侧翼保守基因。实验结果共获得了33,655bp的DNA序列,运用BlastX搜索对所获得的序列进行同源性分析后,发现了7个推定基因,其中有3个为信息素受体编码基因。再根据信息素前体所具有的保守基序特征,在2个信息素受体编码基因附近发现了4个信息素前体编码基因。首次对香菇的B交配型位点的分子遗传学结构有了比较全面的了解。

| Abstract: | In our previous work, degenerate PCR and chromosome walking technologies were used to obtain one pheromone receptor gene and one pheromone precursor gene from Lentinula edodes. In this study, four pairs of specific primers were designed according to the whole genome sequencing of the protoplast monokaryon of Lentinula edodes strain 135, to amplify STE3-like pheromone receptor gene and its flanking conserved genes in the protoplast monokaryon strain SUP2 derived from Lentinula edodes strain Suxiang and 33,655bp DNA sequence was obtained. By BlastX search, seven putative genes were identified, and three of them are pheromone receptor encoded genes. Furthermore, near to two pheromone receptor genes, four genes encoding proteins with conserved motifs of pheromone precursors were found. This study firstly reveals the molecular organization of the B mating type locus of Lentinula edodes. |
