Naturally occurring deletion mutants are parasitic genotypes in a wild-type nucleopolyhedrovirus population of Spodoptera exigua
Article Abstract:
The genetic composition of a wild-type nucleopolyhedrovirus isolate from Spodoptera exigua from Florida (Se-US2) was obtained by an in vivo cloning procedure because its variant SeMNPV does not replicate absolutely in tissue culture. Findings showed that the Se-US2 isolate is composed of at least seven genotype variants, which have been genetically characterized, and that two of the variants are deletion mutants. These two mutants cannot kill S. exigua larvae without a helper virus and interfere with the pest control activities of other variants.

"Candidatus Accumulibacter" population structure in enhanced biological phosphorus removal sludges as revealed by polyphosphate kinase genes
Article Abstract:
The fine-scale population structure of the "Candidatus Accumulibacter" lineage in enhanced biological phosphorus removal (EBPR) systems is examined by employing the polyphosphate kinase 1 gene as a genetic marker. Findings indicate that different clades within the lineage are ecologically distinct.
