  • obligate
  • This overall structural stability resembles that observed in three other obligate endosymbiont clades for which multiple genomes are available, namely, Buchnera aphidicola , " Candidatus Blochmannia" sp. (asm.org)
  • Ca. Sulcia muelleri," the obligate nutritional endosymbiont of cicadas, spittlebugs, and leafhoppers, is their closest relative (Fig. 2 ). (asm.org)
  • Obligate nutritional endosymbionts encounter dramatic reductions in effective population sizes and selective regimens, which contribute to both gene loss and the elevated accumulation of nonsynonymous substitutions ( 2 , 3 , 9 , 13 , 18 ). (asm.org)
  • In this study, we provide the first molecular identification of the bacteriome-associated, obligate endosymbiont in a Gondwanan relict insect taxon, the moss bugs (Hemiptera: Coleorrhyncha: Peloridiidae), which represents one of the oldest lineages within the Hemiptera. (wiley.com)
  • genome
  • While highly reduced (656,901 bp) compared with C. burnetii (1,995,281 bp), the CLEAA genome encodes most major vitamin and cofactor biosynthesis pathways, implicating CLEAA as a vitamin provisioning endosymbiont. (nih.gov)
  • Here, we present the complete genome sequence of the uncultured Bacteroidales endosymbiont of the cellulolytic protist Pseudotrichonympha grassii, which accounts for 70% of the bacterial cells in the gut of the termite Coptotermes formosanus . (sciencemag.org)
  • Results revealed that Xiphinematobacter had a small 0.916-Mb genome with only 817 predicted proteins, resembling genomes of other mutualist endosymbionts. (oregonstate.edu)
  • Buchnera
  • But another example of such transfer to an endosymbionts has recently been uncoveredby Nakabachi and collaborators in the relatively well-studied pea aphid and its symbiotic bacterium, Buchnera aphidicola . (asmblog.org)
  • americanum
  • Our results are important for strategies geared toward controlling A. americanum and the pathogens it vectors, and also contribute novel information regarding the metabolic interdependencies of ticks and their nutrient-provisioning endosymbionts. (nih.gov)
  • muelleri
  • Elevated dN is also observed in " Ca. Sulcia muelleri" and the sequenced gammaproteobacterial endosymbionts (Table 1 ). (asm.org)
  • Consistent with previous phylogenies, Blattabacterium (in bold) is sister to " Ca . Sulcia muelleri," endosymbiont of cicadas, leafhoppers, and spittlebugs, and falls just inside the Flavobacteriales . (asm.org)
  • genes
  • With all this to-and-from on the organellar front, why shouldn't some proteins encoded by nuclear genes be transferred to present day endosymbionts as well? (asmblog.org)
  • The molecular phylogeny was inferred based on two mitochondrial genes for the termites and nuclear small-subunit rRNA genes for the protists and their endosymbionts, and these were compared. (unboundmedicine.com)
  • aphid
  • Lv N, Wang L, Sang W, Liu C-Z, Qiu B-L. Effects of Endosymbiont Disruption on the Nutritional Dynamics of the Pea Aphid Acyrthosiphon pisum . (mdpi.com)
  • bacteriocytes
  • We report that the weevil coleoptericin-A (ColA) antimicrobial peptide selectively targets endosymbionts within the bacteriocytes and regulates their growth through the inhibition of cell division. (sciencemag.org)
  • Silencing the colA gene with RNA interference resulted in a decrease in size of the giant filamentous endosymbionts, which escaped from the bacteriocytes and spread into insect tissues. (sciencemag.org)
  • hosts
  • Nevertheless, insect hosts also need to sustain control mechanisms to prevent endosymbionts from unregulated proliferation. (mdpi.com)
  • The endosymbiont theory has in fact been considered extensively in the context of intragenomic conflict, that is, in terms of the evolutionary dynamics of mitochondria and their hosts in a more or less modern form (e. (thefreedictionary.com)
  • present
  • The present work examined the densities of each endosymbiont in adult D. citri sampled from different populations using quantitative PCR. (springer.com)
