I analyse illegitimate recombination events mediated by the bacteriophage h int gene by comparing the DNA sequences of a bacteriophage /\ hybrid containing the Saccharomyces cerewisiae (yeast) hid gene and five independently derived deletion mutants. Behaviours of these Ahis deletion mutants with respect to i&mediated recombination and to his3 gene expression are examined. Observations made are...
A sediment core spanning approximately 1,600 years was collected from a lake on Ardley Island, Antarctica. The sediment core had been greatly influenced by penguin guano. Using molecular methods, the chitinolytic bacterial community along the sediment core was studied over its entire length. Primers targeting conserved sequences of the catalytic domains of family 18 subgroup A chitinases detect...
UNLABELLED The prokaryotic pangenome partitions genes into core and dispensable genes. The order of core genes, albeit assumed to be stable under selection in general, is frequently interrupted by horizontal gene transfer and rearrangement, but how a core-gene-defined genome maintains its stability or flexibility remains to be investigated. Based on data from 30 species, including 425 genomes f...
