胃蛋白酶元Ⅰ-
We excised the pgn fragment, which contains a camv 35s promoter a gus gene and a nos terminator from the plant expression vector pbi121 with ecor i and hindlll and inserted it between the ecor i and hindlll sites of the plant expression vector pcambia3301, yielding pc3301 - pgn. the hf2 fragment was excised from pg - ho with xba i and sac i and then cloned between the xba i and sac i sites of the plant expression vector pc3301 - pgn to produce pc3301 - hf2
將pbi121植物表達載體上含有camv35spromoter 、 gusgene和nosterminator的pgn片段酶切下來，連接到植物表達載體pcambia3301上，構建成中間載體pc3301 - pgn ，然後用hf2dna片段替換pc3301 - pgn載體上的gus基因，構建成植物表達載體pc3301 - hf2 ， hf2dna正向插入在植物表達載體35s啟動子的下游。
