[Degradation of nicosulfuron by combination effects of microorganisms and chemical hydrolysis].

A strain which was capable of degrading nicosulfuron in the presence of glucose was isolated from nicosulfuron contaminated wetland soil, and it was identified as Klebsiella sp. based on 16S rDNA gene sequencing analysis. The strain could grow using nicosulfuron as the sole nitrogen source.

Genetic diversity in the mycoparasite Sphaerellopsis filum inferred from AFLP analysis and ITS-5.8S sequences.

Genetic diversity among 51 isolates of the mycoparasite Sphaerellopsis filum from Melampsora rusts on willow and poplar was examined using AFLP. Genetic variation was relatively low among the isolates (Nei & Li's similarities > or =90). Genetic diversity calculated using Shannon index was 0.
