Abstract
The cells from natural isolates of A. Brasilense were found to harbour 1 to 4 plasmids with the molecular masses within the 27-300 Md range. 100 Md plasmids are specific for this bacterial species. Strains isolated from the roots of cereals (wheat, maize, barley) have more heterogeneous plasmid composition as compared to the strains isolated from soil.
摘要
研究发现，来自巴西固氮螺菌自然分离株的细胞含有1至4个质粒，其分子量在27 - 300 Md范围内。100 Md的质粒是该细菌物种特有的。与从土壤中分离的菌株相比，从谷物（小麦、玉米、大麦）根部分离的菌株具有更异质的质粒组成。
