Food selection by bacterivorous protists: insight from the analysis of the food vacuole content by means of fluorescence in situ hybridization.

abstract：:We re-evaluated PCR primers targeting nirS, nirK and nosZ genes for denaturing gradient gel electrophoresis as a tool to survey denitrifying community composition in environmental samples. New primers for both nirS and nosZ were combined with existing primers, while for nirK the previously published F1aCu:R3Cu set was...

Helping close relatives that are likely to share the same genes (kin selection) is one important explanation that is likely to apply across taxa.
