  • density
  • Results have: (1) identified previously unreported lobate tissue morphologies on the outer wall of individual coral polyps and (2) created the first surface maps of the 3D distribution and tissue density of chromatophores and algae-like dinoflagellate zooxanthellae endosymbionts. (jove.com)
  • bacteria
  • Many plasmids are available that carry genes encoding proteins that fluoresce at different wavelengths ( i.e. green or red), and conjugation of plasmids from a donor Escherichia coli strain into a recipient bacterial symbiont is successful for a broad range of bacteria. (jove.com)
  • Discriminating the frequency and load of colonizing bacteria can be especially important when screening or characterizing bacterial mutants for colonization phenotypes 21 , 24 . (jove.com)
  • important
  • Results obtained using this laboratory assay are an important prelude to field experiments that rely on the feeding responses of a full complement of potential predators. (jove.com)
  • THE colors and patterns on animal body surfaces are often important for visual communication in the wild and are determined primarily by pigment cells (chromatophores) in vertebrates. (genetics.org)
  • environmental
  • Assays of extracellular enzyme activity in environmental samples typically involve exposing the samples to artificial colorimetric or fluorometric substrates and tracking the rate of substrate hydrolysis. (jove.com)
  • types
  • Spectral absorption peaks of 500 nm and 675 nm, respectively, suggest that M. annularis and M. faveolata contain similar types of chlorophyll and chromatophores. (jove.com)
  • The chromatophores are distributed in the skin, and their types, sizes, densities, and physiological activities affect these colors and patterns. (genetics.org)

  • In the same way the bacterial organisms attached to the surface of seaweed shows alteration of genes expression may be due to the response to the high competitive environment. (gilroypheromones.com)
  • The successful combination of the molecular model and the systemic parametrization presented here on the example of the simple machinery for bacterial photosynthesis shows that it is actually possible to combine molecular and systemic modeling. (jove.com)
