3.
To characterize the precise function ofβ-mannosidase in cotton fiber, in this study,the sense and antisense coding sequence of theβ-mannosidase gene were fused withfiber-specific E6 promoter to build the constructs of sense gene and antisense RNA gene,and with which to transform into cotton via Agrobacterium-mediated transfor.
为了研究β-甘露糖苷酶(GhManA2)在棉纤维发育中的确切功能，本研究将其基因序列以正向，反向构建到由纤维特异启动子E6驱动的植物表达载体pBI121中，通过农杆菌介导法将其转入棉花，试图通过该基因在纤维发育中的过量表达和抑制表达对棉纤维发育的影响来研究其在纤维发育中的确切功能。
补充资料：莨菪亭-β-樱草糖苷(seopoletin-β-pimeoeroside)
分子式：
CAS号：
性质：又称莨菪亭-β-樱草糖苷(seopoletin-β-pimeoeroside)。黄色针状结晶，熔点236～238℃。于130℃时失去结晶水。旋光度-140°(水中)。易溶于热水，难溶于有机溶剂。水溶液中加入氨或碱，即呈现黄色。由酸水解，则产生莨菪亭。莨菪亭与六乙酰-α-樱草糖基溴缩合成六醋酸酯。为一种香豆素衍生物。存在于茄科植物皮葜茄(fabina imbricate Ruiz et pavon)的枝中。由萃取而得。用作调香剂。
