水稻T-DNA插入启动子捕获系的初步筛选
Preliminary Screening of Rice Promoter Trap Lines with T-DNA Tagging
摘要
Abstract
Binary vector pCAMBIA1300GUSA-Hyg containing β-glucuronidase (GUS) without the promoter was introduced into Oryza sativa L. Minghui 86 by agrobacterium-mediated transformation. The χ2 tests on the hygromycin resistant ratio revealed that 28 of the 39 rice promoter trap lines contained a loci T-DNA tagging. GUS histochemical assay at different stages in different organs, such as root, stem, leave, anther, hull, embryo and emdospern, of 2 653 rice promoter trap lines was performed. The results showed that 83 rice promoter lines were GUS positive. Of all tested, 24 lines were expressed in endosperm (i. e. , 0. 91 %) and 19 lines expressed in anther (i. e. , 0. 72%). Information collected on the rice promoter trap lines could be useful in identifying new rice genes.关键词
