Screening Transgenic Arabidopsis Expressing GFP:: cDNA Fusions and Functional Analysis of Related Gene
摘要
Abstract
Transgenic Arabidopsis expressing random GFP: :cDNA fusions was used in this study. 58 Basta-resistant transgenic lines which expressing GFP: :cDNA fusions in nuclei or in both nuclei and cytoplasm were obtained. The cD-NA fragment inserted into the transgenic plants were cloned and analyzed, and only four lines which express an in-frame fusion were obtained. Phynotype of one transgenic line R2, which expressing an in-frame fusion to a Gly-rich carboxy-terminal domain of AtGRP8 protein, was analyzed. The hypocotyl of Rl seedlings were shorter than that of wild type col-4 grown in continuous white, blue or red light, especially under relative lower fluence rate white ( less than 100 μmol m-2 s-1) or blue (less than 75μmol m-2 s-1) light, but there was no difference in the hypocotyl length when grown in the dark. The results indicated that AtGRP8 may be involved in controlling the photomorphogenesis of Arabidopsis seedling through its Gly-rich carboxy-terminal domain.关键词
