The results revealed that there was the toxicity effect of 6 different carbamic ester pesticides on Anabaena flos-aquae. 结果发现,6种氨基甲酸酯类农药对水华鱼腥藻都有不同程度的毒性作用。
Anabaena sp. PCC 7120 cyanobacterial phytochrome gene AphA and its truncated mutant aphA (N-25/C-445) were PCR amplified and cloned. 通过PCR技术;从蓝藻PCC7120中扩增出细菌光敏色素AphA的基因aphA;进而构建aphA的缺失突变体aphA(N25/C445).
In northern latitudes in summer, extensive growth of Anabaena may form water blooms that remain suspended instead of forming a surface scum. 北纬夏季，鱼腥藻可形成水花，悬浮水中而非形成水表面的浮渣。
The LOECNOEC and MATC of 6 carbamic ester pesticides to Anabaena flos-aquae were researched so that the pesticides were reasonably and safely used in the environment. 同时研究了氨基甲酸酯类农药对水华鱼腥藻的LOEC、NOEC和MATC值,发现不同农药的LOEC、NOEC和MATC值也不相同。
Susceptibility of acetolactate synthase (ALS) was compared in vitro and in vivo in Anabaena flos-aquae todetermine the mechanism of ALS inhibition by metsulfuron. 以水华鱼腥藻的乙酰乳酸合成酶(ALS)比活力作为研究对象,通过在离体和活体条件下比较其对甲磺隆的敏感性,探讨了甲磺隆对水华鱼腥藻的作用机理。
