  • Strains
  • The most studied associations are those with plants, where strains of Nostoc are the common cyanobacterial partner. (diva-portal.org)
  • From the studies, many different Nostoc strains are involved in the two symbiotic associations, although no variation was observed within a single bryophyte cavity or cycad coralloid root. (diva-portal.org)
  • In these symbioses, both the hosts and the cyanobacterial partners are rather promiscuous, when the plant partners accept a wide range of Nostoc and a Nostoc strains isolated from one plant species is capable of infection phylogenetically distant hosts ( Johansson and Bergman, 1994 ). (frontiersin.org)
  • Unexpectedly, integrated transcriptional and metabolomics studies uncovered a major reprogramming of the secondary metabolome of two Nostoc strains at high culture density and a governing effect of extracellular signals in this process. (asm.org)
  • The present study not only demonstrates the suitability of a recently developed two-tier vessel cultivation approach for the rapid generation of biomass of Nostoc strains but also demonstrates a pronounced upregulation of high value natural products at ultrahigh culture densities. (asm.org)
  • strain
  • The presence of the mysABCD gene cluster in N. commune strain KU002 (genotype A) supported its porphyra-334 producing capability via the Nostoc -type mechanism, although the genotype A of N. commune mainly produces the arabinose-bound porphyra-334. (go.jp)
  • Here, interactions between the filamentous heterotrophic bacteria Fibrella aestuarina (strain BUZ 2) and Fibrisoma limi (BUZ 3) with an axenic strain of the autotrophic filamentous cyanobacterium Nostoc muscorum (SAG 25.82) were studied in mixed cultures under nutrient rich (carbon source present in medium) and poor (carbon source absent in medium) conditions.

  • bacteria
  • Similar to other forms of bacteria, the single-celled Nostoc does not have a nucleus or other internal membrane systems and the cytoplasm is comprised of between seventy and eighty-five percent water. (microscopyu.com)
  • Nostoc'', first discovered in the 19th century, is one of the most widespread phototrophic bacteria in the world. (kenyon.edu)
  • taxa
  • 50 nonoxygenic bacterial genera (taxa other than Nostoc ) that indicate diverse ecological functions. (wiley.com)
  • NaCl
  • Nostoc ellipsosporum was more NaCl tolerant and attained more biomass under salinity than N. piscinale.Accumulation of proline was detected in N. ellipsosporum under salinity stress. (deepdyve.com)
  • isolates
  • STRR fingerprinting and 16S rDNA phylogeny reconstruction showed a remarkable local diversity among isolates assigned to several Nostoc clades. (frontiersin.org)
  • nitrogen
  • Also, a better understanding of soil-dwelling nitrogen fixers such as ''Nostoc'' may help advance fertilizer production and benefit agriculturalists. (kenyon.edu)
  • gene
  • CONCLUSION: This study demonstrated that five ORFs upstream of the hyp-gene cluster are co-transcribed with the hyp-genes, and identified three TSPs in the extended hyp-gene cluster in Nostoc sp. (biomedsearch.com)
  • The complete gene sequence was isolated from a genomic Nostoc sp. (diva-portal.org)
