Lack of expression of competence related genes is expected as THB medium used for propagating S. pneumoniae does not support competence.
There might be a priming mechanism in which longer exposure to activated Smad2 increases gene expression when competence is reached.
The timely expression of competence genes allows the larva to disperse widely before settlement, navigate towards a suitable habitat, detect appropriate inductive cues, and adhere to its chosen substrate.
Phosphorylated ComE drives the expression of early competence genes (Claverys and Havarstein 2007).
However, the regulatory processes controlling expression of these competence genes are very different in the different organisms [ 2].
L. fuelleborni shows the greatest region of dental competence (expression of pitx2), consistent with the later elaboration of teeth and tooth rows.
We previously defined populations of TCR-ζdim T cells in peripheral blood with characteristics of prior antigen experience, based on cell surface phenotype, cytokine expression and migratory competence [ 16].
Finally, HutP is directly involved in the use of alternative carbon and nitrogen sources [ 67], but was clustered in the Cell differentiation module because it is regulated by the master regulator AbrB and the CodY TF, which regulate gene expression during the competence state.
The observed lack of DNA uptake by gut bacteria might also be related to the lack of expression of bacterial competence inside the gut, insufficient free DNA concentrations, suboptimal biochemical conditions for transformation that the use of assay methods were not sensitive enough for detecting low levels of transformation.
Some attempts were made to relate the gene expressions to developmental competence of oocytes.
Using the same reporter fusion, this research group performed single-cell analyses on the expression patterns of both competence development and sporulation of a B. subtilis culture of a 1 : 1 mix spore induction: competence induction in chemically defined liquid media and also in biofilms.
