Regulation of Cellular Differentiation in Filamentous Cyanobacteria in Free-Living and Plant-Associated Symbiotic Growth States
  • J. Meeks, J. Elhai
  • Biology
    Microbiology and Molecular Biology Reviews
  • 1 March 2002
TLDR
The physiology of symbiotically associated cyanobacteria raises the prospect that heterocyst differentiation proceeds independently of the nitrogen status of a cell and depends instead on signals produced by the plant partner.
Growth and photosynthesis in an extreme thermophile, Synechococcus lividus (Cyanophyta)
TLDR
The data suggest that the photosynthetic system could be involved in determining both the upper and lower limits of growth in this organism.
An overview of the genome of Nostoc punctiforme, a multicellular, symbiotic cyanobacterium
TLDR
Comparative analysis of the shotgun-sequencing phase of the N. punctiforme strain ATCC 29133 genome indicates a genome that is highly plastic and in a state of flux, with numerous insertion sequences and multilocus repeats, as well as genes encoding transposases and DNA modification enzymes.
Cellular differentiation in the cyanobacterium Nostoc punctiforme
TLDR
The regulatory circuits of three cellular differentiation events and symbiotic interactions of N. punctiforme can be experimentally analyzed by functional genomics and hypothesized to depart from the vegetative cell cycle following separate and distinct events.
Polymorphism at the C-reactive protein locus influences gene expression and predisposes to systemic lupus erythematosus.
TLDR
The hypothesis that defective disposal of potentially immunogenic material is a contributory factor in lupus pathogenesis is supported and the identification of polymorphisms that determine basal CRP levels has implications in ischaemic heart disease, where CRP level is an important predictor of risk.
Genetic evidence of a major role for glucose-6-phosphate dehydrogenase in nitrogen fixation and dark growth of the cyanobacterium Nostoc sp. strain ATCC 29133
TLDR
Results unequivocally establish that G6PD, and most likely the oxidative pentose phosphate pathway, represents the essential catabolic route for providing reductant for nitrogen fixation and respiration in differentiated heterocysts and for dark growth of vegetative cells.
The Azolla-Anabaena Symbiosis: Basic Biology
TLDR
Article de synthese sur la symbiose entre Azolla et Anabaena, sa perpetuation sur l'interaction plante-microorganisme et son interet en tant que biofertiliseur dans the culture du riz.
Molecular Genetics and Genomic Analysis of Scytonemin Biosynthesis in Nostoc punctiforme ATCC 29133
TLDR
This study obtained a scytonemin-deficient mutant of the cyanobacterium Nostoc punctiforme ATCC 29133 by random transposon insertion into open reading frame NpR1273, and revealed an 18-gene cluster, which is likely to be biosynthetic precursors of the sunscreen.
Global Gene Expression Patterns of Nostoc punctiforme in Steady-State Dinitrogen-Grown Heterocyst-Containing Cultures and at Single Time Points during the Differentiation of Akinetes and Hormogonia
TLDR
The differentiation of heterocysts (steady state, N(2) grown), akinetes, and hormogonia appears to involve the up-regulation of genes distinct for each state, consistent with entry into a nongrowth state.
SYMBIOSIS BETWEEN NITROGEN-FIXING CYANOBACTERIA AND PLANTS
  • J. Meeks
  • Environmental Science, Biology
  • 1 April 1998
TLDR
As a group, oxygenic photoautotrophic cyanobacteria, especially those species that fix nitrogen, are the most nutritionally independent organisms in the biosphere because of this nutritional independence, as well as their tolerance to physicochemical extremes.
