Cotton Transformation Based on Inverted Repeat Construct of stearoyl-ACP △9 desaturase GeneghSAD-1
摘要
Abstract
A partial inverted repeat based gene construct was produced and cloned into the pBI-Lectin binary vector, using the strong seed specific soybean Lectin promoter and cotton stearyol-ACP △9 desaturase gene ghSAD-1.The cotton cultivar G. hirsutum cv. Coker315was then transformed by the construct through Agrobacteriurn mediated infection. A relatively high transformation frequency was obtained.Further analysis by PCR, Southern blotting and fatty acid composition analysis demonstrated that the expression or silencing effectiveness of the transgene was not in the same level among various transgenic lines, where the stearic acid content was increased from 2 percent of the control to a range of 4 ~ 38. 2 percent. These materials are valuable for the further improvement of current cottonseed oil in the future.关键词
