Genetic population structure of the soil bacterium Myxococcus xanthus at the centimeter scale

Article Abstract:

The small-scale production structure of Myxococcus xanthus is investigated by isolating several clones from a small patch of soil (16 by 16 cm) in Tubingen, Germany. The analysis has indicated that M. xanthus is surrounded by a variety of conspecifics in its natural soil habitat at a spatial scale at which encounters among genotypes are likely.

Relative abundances of proteobacterial membrane-bound and periplasmic nitrate reductases in selected environments

Article Abstract:

The investigation of the relative abundances of two types of nitrate reductases in various environments using a real-time PCR assay is presented. Findings suggest the high correlation between narG and napA gene copy numbers in soils, which indicate the ecological roles of the corresponding enzymes.

Copper-adapted Suillus luteus, a symbiotic solution for pines colonizing Cu mine spoils

Article Abstract:

A population of the ectomycorrhizal fungus Suillus luteus that colonized a toxic Cu mine spoil in Norway is described. The population has developed adaptive Cu tolerance and is able to protect pine trees against Cu toxicity.
