    • Problem: To provide a fungal bed culture enabling stable production of a hon-shimeji mushroom in large scale commercial cultivation as well as a method of fungal bed cultivation of a hon-shimeji mushroom using the fungal bed culture.Solution: There is provided a fungal bed culture of a hon-shimeji mushroom inoculated with a liquid seed culture characterized in that the surface of a culture medium for cultivation has a liquid seed culture inoculated portion and a liquid seed culture non-inoculated portion as well as a fungal bed cultivation method of a hon-shimeji mushroom characterized by generating a fruit body from the fungal bed culture. According to the present invention improves the formation rate of budlet in the fungal bed cultivation of a hon-shimeji mushroom, thereby enabling stable production of a hon-shimeji mushroom in large scale commercial cultivation.
    • 问题:提供一种真菌床文化,能够在大规模商业栽培中稳定生产一种香菇菇,以及使用真菌床培养方法真菌床栽培枸杞子蘑菇。 解决方案:提供了接种液体种子培养物的枸杞蘑菇的真菌床培养物,其特征在于用于培养的培养基的表面具有液体种子培养接种部分和液体种子培养未接种部分 作为真菌床栽培方法,以真菌床培养物产生果实为特征。 根据本发明,提高了枸杞蘑菇真菌床栽培中芽的形成速率,从而在大规模商业栽培中稳定地生产了一种枸杞子蘑菇。

    • A method for performing site-directed mutagenesis characterized in that the method includes the step of carrying out PCR by the use of a double-stranded DNA vector having one or more amber codons, the vector resulting from insertion of a target DNA fragment for site-directed mutagenesis, and at least two kinds of selection primers; and a kit for site-directed mutagenesis for use in the above method, characterized in that the kit includes amber codon reversion primers. According to the present invention, there can be provided a method for performing site-directed mutagenesis and a kit, which is useful for genetic engineering or protein engineering, more simply and rapidly. By using the method and the kit of the present invention, it is possible to efficiently obtain a mutation-introduced gene at the desired position by simply transforming a host with a PCR product obtained by PCR.
    • 一种用于进行定点诱变的方法,其特征在于该方法包括通过使用具有一个或多个琥珀密码子的双链DNA载体进行PCR的步骤,所述双链DNA载体由插入靶DNA片段所产生的载体, 定向诱变和至少两种选择引物; 以及用于上述方法的用于定点诱变的试剂盒,其特征在于所述试剂盒包括琥珀密码子反转引物。 根据本发明,可以提供用于进行定点诱变的方法和用于遗传工程或蛋白质工程的试剂盒,其更简单和快速。 通过使用本发明的方法和试剂盒,通过用PCR获得的PCR产物简单地转化宿主,可以有效地获得所需位置的突变导入基因。
