摘要
将Fibrillin操纵子驱动的荧光素酶报告基因表达载体导入拟南芥原生质体中,研究基因表达调控,证明脱落酸(ABA)诱导报告基因的表达.同时将相同的质粒转化到甘蓝型油菜蜀杂9号原生质体中,获得与拟南芥中类似的表达结果.实验结果说明Fibrillin操纵子在拟南芥和油菜原生质体中均对ABA的诱导敏感.
Arabidopsis fibrillin promoter was constructed in pBI221, and the plasmid was transferred into protoplasts of Arabidopsisor Brassicavia PEG-mediated method, showing a transient expression. After adding 30μmol/L ABA, it was found that the expression was upregulated, indicating fibrillin is sensitive to ABA in both Arabidopsis thaliana and Brassica napus.
