Construction of male sterility expression vector by integration of artificial sense and antisense cdnas of hsp70 into puc18 and puc19 respectively, we can obtain psc and pac. tapertal specific expression promoter ta29 and terminator nos are connected directionally with sense and antisense cdnas of hsp70 extrected and purified from psc and pac., then integrated into puc18 and puc19, by which we can build sense and antisense cdna nos ( respectively named plasmid 650 and plasmid 651 ) of ta29 - hsp70. for the sake of better screening and examination of transformed gene, we cut plasmid 650, plasmid 651 and 3301 ( containing gusgene bar screening marker gene ) with hindiii and ecor i enzymes, then connect purified fragments of 650and 651 with plasmid 3301 to construct the vector 3301 + 650 and 3301 + 651. corroboration of whether sense and antisense cdna - nos is integrated into plasmid3301 can be made by plate screening and enzye - cutting analysis
分別將從psc 、 pac回收純化的hsp70正、反義cdna與絨氈層特異表達啟動子ta29及nos終止子定向連接，然後插入到puc18 、 puc19中，構建成花藥特異表達的ta29 - hsp70sensecdna - nos和ta29 - hsp70antisensecdna - nos ，分別稱作650和651質粒。為了更好地對轉化子進行篩選和檢測，用hind和ecor分別對650 、 651及3301質粒（含gus報告基因和bar篩選標記基因）進行酶切，將從650和651回收純化的目的片段與3301質粒進行連接，再對重組子進行平板篩選和酶切分析確定ta29 - hsp70sensecdna - nos和ta29 - hsp70antisensecdna - nos插入到3301質粒中，構建成3301 + 650和3301 + 651表達載體。 -
