In this exper iment, we took the advantage of RNAi technique, microinjected tinman and wingless dsRNA into the early embryos in Drosophila respectively and got these two genes' RNAi phenotypes, which were very similar to that of their mutant, showing heart tube defects or no heart precursors formation.

实验运用RNAi技术，分别将tinman和wingless的dsRNA注入果蝇的早期胚胎，得到了这两个基因的dsRNA干扰表型，与两个基因的突变体表型非常相似，都表现为果蝇心脏前体细胞不能形成或心脏管缺失。

The purpose of the experiment is to realize the prokaryotic expression of β-glucosidase gene from Acetobacter xylinum ATCC 23769, which will be used to produce enzyme preparation so as to develop the efficiency of extracting resveratrol from plants. Aspergillus niger β-glucosidase gene is cloned both at DNA lever and cDNA lever, which will lay a foundation for further research about its expression in Saccharomyces cerevisiae in a secretory form with the aim of increasing resveratrol contents in wines.

In the T1 generation, ten from 30 plants showed kanamycin-resistance. And, PCR amplification confirmed that 8 plants of them had specific fragment of chitinase, but no specific fragment ofβ-1, 3-glucanase. In this study an amaranth agglutinin gene was also cloned from Amaranthus retroflexus for obtaining aphids resistant transgenic cotton.
