The physiological state of competence for natural transformation allows bacteria to take up free DNA from the environment and recombine it into their genome. As one of three modes of horizontal gene transfer, natural transformation has hence contributed su ...
Numerous diseases affecting living beings have as a cause a modification of gene expression resulting in anomalous expression of proteins in up- or down-regulated fashion, with altered functions or expression of proteins that are not present in the cell in ...
The human pathogen Vibrio cholerae is an autochthonous inhabitant of aquatic environments where it often interacts with zooplankton and their chitinous molts. Chitin induces natural competence for transformation in V. cholerae, a key mode of horizontal gen ...
My PhD thesis aims to obtain the structure of several bacteriophages, including so-called “jumbo” phages, using the electron cryo-microscopy (cryo-EM) and to study the structural transformation of these viruses as they attach and infect the host cell. We a ...
Natural competence enables bacteria to take up exogenous DNA. The evolutionary function of natural competence remains controversial, as imported DNA can act as a source of substrates or can be integrated into the genome. Exogenous homologous DNA can also b ...
Horizontal gene transfer (HGT) is widespread in bacteria and archaea and plays a significant role in prokaryotic evolution. One mode of HGT is natural competence for genetic transformation, which allows the organism to take up free DNA from its surrounding ...
Natural competence for transformation is a developmental program that allows certain bacteria to take up free extracellular DNA from the environment and integrate this DNA into their genome. Thereby, natural transformation acts as mode of horizontal gene t ...
Vibrio cholerae, the causative agent of cholera, is a model organism for studying virulence regulation, biofilm formation, horizontal gene transfer, and the cell-to-cell communication known as quorum sensing (QS). As in any research field, discrepancies be ...
The physiological state of natural competence for transformation allows certain bacteria to take up free DNA from the environment and to recombine such newly acquired DNA into their chromosomes. However, even though conserved components that are required t ...
The human pathogen Vibrio cholerae is an aquatic bacterium associated with zooplankton and their chitinous exoskeletons. On chitinous surfaces, V. cholerae initiates a developmental programme, known as natural competence, to mediate transformation, which i ...
