The studies on intraspecific variation of Batrachospermum gelatinosum and B.intortum have been made. The results show that the intraspecific variation is widespread. Most of numerical characters are in great variable range. Compared with the reproductive organs, the vegetative organs are more variable to vary.
对胶串珠藻和绞扭串珠藻的种内形态变异进行了初步研究,结果表明,种内形态变异现象普遍存在,变异范围较大的,多属数量性状,且营养结构较生殖结构特征具有更大的变异性。

The ultrastructure characters of pollen grain in Brassica napus are:1There are vacuoles in cytoplasm but no starch grain in uniceelluar pollengrain.2The veget- ative nucleus of bicellular pollen grain is generally spheroidal;while the generative cell is spinde-shaped,with a big nucleus,thin layer of cytoplasmand few cell orgens,no cell wall.3In three-celled pollen grain the sperm cell is separated from the cytoplasm of vegetative cell by two layers of plasmic membrances.
Brassica napus的花粉粒,在不同发育时期超微结构的特征如下:1单胞花粉粒有一个球形的细胞核和明显的核仁,细胞质内出现液泡,缺少典型的淀粉粒。2双胞花粉粒的营养核多为球形。生殖细胞纺锤形,无细胞壁,细胞核比例大,细胞质呈薄层,细胞器少。3三胞花粉粒有一个裂片状的营养核和两个纺锤形的精细胞,精细胞无壁,以两层质膜与营养细胞的细胞质相隔。

The GPA1 gene was obtained via PCR amplification and was cloned in the two-hybrid DNA binding domain vector pGBKT7 The combinant plasmid was designated as pGBKT7-Ga.β-galactosidase assay indicatedthat Got did not have the property of self-activation. After pGBKT7-Ga was transformed to yeast pJ69-4A, we transformed Arabidopsis vegetative tissue two-hybrid cDNA library plasmids to yeast pJ69-4A containing pGBKT7-Ga.
通过PCR扩增得到GPA1基因并将其克隆到双杂交DNA结合域载体pGBKT7中,得到的重组质粒命名为pGBKT7-Gα,β—半乳糖苷酶活性鉴定表明Gα不具有自激活特性,将其转化到酵母菌pJ69-4A中,再以此为受体菌转化拟南芥绿色营养组织cDNA文库质粒。
