• Factors
  • B. bronchiseptica does not express pertussis toxin, which is one of the characteristic virulence factors of B. pertussis, but it has the genes to do so, highlighting the close evolutionary relationship between the two species. (wikipedia.org)
  • gene
  • However, this occurred independently of the duplications in mice, meaning that both rodent species expanded their Mup gene families separately, but in parallel. (wikipedia.org)
  • The question of how far the NP gene can cross the species barrier by reassortment and become adapted by mutation to the new host has been discussed. (wikipedia.org)
  • genes
  • A reference genome (also known as a reference assembly) is a digital nucleic acid sequence database, assembled by scientists as a representative example of a species' set of genes. (wikipedia.org)
  • Mups are encoded by a cluster of genes, located adjacent to each other on a single stretch of DNA, that varies greatly in number between species: from at least 21 functional genes in mice to none in humans. (wikipedia.org)
  • In 2008 a more precise number of Mup genes in a range of species was determined by analyzing the DNA sequence of whole genomes. (wikipedia.org)
  • high
  • An NtcA peptide was found to target multiple cyanobacteria species, whereas a P-II peptide showed specificity to the high-light Prochlorococcus ecotype. (mblwhoilibrary.org)
  • Invasive species can quickly transform biological communities due to their high abundance and strong impacts on native species, in part because they can be released from the ecological forces that limit native populations. (mendeley.com)
  • As is common with parasitic species C. fasciculata requires a high nutrient content broth (including heme and folic acid) in which to grow under laboratory conditions. (wikipedia.org)
  • range
  • These patterns are consistent with the finding of slowing A. petiolata population growth and rebounding native species abundance across a separate chronosequence in Illinois, U.S. These results suggest that this invader is developing evolutionary limits in its introduced range and highlight the importance of understanding the long-term processes that shape species invasions and their impacts.

  • Type
  • The hepatitis B virus is classified as the type species of the Orthohepadnavirus, which contains three other species: the Ground squirrel hepatitis virus, Woodchuck hepatitis virus, and the Woolly monkey hepatitis B virus. (wikipedia.org)
  • The binding specificity of Type I interaction was well studied by structural and mutagenesis studies. (wikipedia.org)

  • example
  • In some species (for example, in hydroids like Campanularia or tunicate like Ciona), the swimming direction of the spermatozoa changes abruptly towards the chemoattractant source. (wikipedia.org)
  • In some species (for example, herring or the ascidian Ciona) activation of motility precedes chemotaxis. (wikipedia.org)
  • male
  • Females of both species showed no attraction to the odors of conspecific individuals, male or female, and C. glomerata females even appeared to be repelled by mated males. (mdpi.com)
  • The only species with which the male is easily confused is the Eurasian tree sparrow, which differs in its black cheek spot and brown back. (wikipedia.org)
  • cats
  • In some species, such as cats and pigs, Mups appear not to be expressed in urine at all and are mainly found in saliva. (wikipedia.org)
  • Although
  • Although the pistil is a great facilitator of pollen function, it can also be viewed as an elaborate barrier that shields ovules from access from inappropriate pollen, such as pollen from other species. (valpo.edu)
  • found
  • Moreover, the pheromones were found to be highly specific, as males were not attracted by females of the other species. (mdpi.com)
