  • Here we exploit the transparent young Striga asiatica seedling to (i) localize the site of H2O2 accumulation to the surface cells of the primary root meristem, (ii) demonstrate the accumulation of H2O2 within cytoplasmic and apoplastic compartments, and (iii) document precise regulation of H2O2 accumulation during development of the host attachment organ, the haustorium.

  • For example, in Striga asiatica, an obligate hemi-parasite of grasses, the hydroquinone sorghum xenognosin for Striga germination (SXSg) is necessary and sufficient for inducing Striga seed germination (Chang et al. (dadospdf.com)
  • Among social parasites, the ant nest beetles ( Paussus ) are obligate myrmecophiles able to move throughout the colony at will and prey on the ants, surprisingly never eliciting aggression from the colonies. (plos.org)
  • Nishith Gupta's research focuses on metabolic interactions between intracellular parasites and host cells. (wikipedia.org)
  • Nevertheless, in today's review, we will discuss mobile and humoral immunities with a particular concentrate on the reputation and signaling pathways of web host cells and triggering parasite elements in a thorough survey approach to previous reports. (thetechnoant.info)
  • Large-scale coordination of cells may well be mediated by hydrodynamic interactions that do not depend on the exchange of chemical signals. (uni-wuerzburg.de)
  • In the human bloodstream, the deadly parasites are precisely biomechanically adapted to the presence of blood cells and exhibit very rapid forward movement, which is essential for clearing host antibodies from the cell surface. (uni-wuerzburg.de)
  • Dissecting the dynamics of this L1-host 'arms race' will help to better decipher our genome dynamics in relation to cancer, brain development, reproduction, and potentially to other human diseases. (genengnews.com)
  • For the parasites (and pathogens) that cause these diseases in animals, social interactions are a golden opportunity to transmit. (springernature.com)
  • The computations underlying social interactions are highly distributed across many brain areas. (stanford.edu)
  • However, many such parasites produce their effects by releasing compounds that act on the neural circuitry of the host. (frontiersin.org)
  • To name just a few examples, some worms induce crickets and other terrestrial insects to commit suicide in water, enabling the exit of the parasite into an aquatic environment favorable to its reproduction. (frontiersin.org)
