以双元载体pPZP100为骨架,通过酶切、连接将标记基因(潮霉素-绿色荧光蛋白,HygR-GFP)及碳色长蠕孢(Helminthosporium carbonum)非核糖体肽合成酶基因(HcNPS6)侧翼序列插入目标载体pPZP100,构建HcNPS6基因敲除载体,并采用冻融法将pPZP100HygR-GFPHcNPS6转入农杆菌菌株AGL-1。挑取经氨苄/氯霉素筛选的重组子进行菌落PCR鉴定。结果表明,敲除载体已成功转入农杆菌AGL-1。
以雙元載體pPZP100為骨架,通過酶切、連接將標記基因(潮黴素-綠色熒光蛋白,HygR-GFP)及碳色長蠕孢(Helminthosporium carbonum)非覈糖體肽閤成酶基因(HcNPS6)側翼序列插入目標載體pPZP100,構建HcNPS6基因敲除載體,併採用凍融法將pPZP100HygR-GFPHcNPS6轉入農桿菌菌株AGL-1。挑取經氨芐/氯黴素篩選的重組子進行菌落PCR鑒定。結果錶明,敲除載體已成功轉入農桿菌AGL-1。

Vector construction was based on the skeleton of pPZP100, HygR-GFP and flanking sequences of HcNPS6 of Helminthosporium carbonum were linked into pPZP100 by restriction enzymes digested and ligase connection. Deletion vector of nonribosomal peptide synthetases 6(NPS6) of Helminthosporium carbonum had been constructed pPZP100HygR-GFPHcNPS6 and transformed into AGL-1 by method of freeze-thaw.
