Ionizing-Radiation Resistance in the Desiccation-Tolerant CyanobacteriumChroococcidiopsis
TLDR
The radiation resistance ofroococcidiopsis strains may reflect the ability of these cyanobacteria to survive prolonged desiccation through efficient repair of the DNA damage that accumulates during dehydration.
Life and death of dried prokaryotes.
The subaerophytic cyanobacterium Oculatella subterranea (Oscillatoriales, Cyanophyceae) gen. et sp. nov.: a cytomorphological and molecular description
TLDR
A new genus and species of subaerophytic cyanobacteria with very thin purple-red trichomes with a photosensitive orange spot at the tip of the trichome containing a rhodopsin-like pigment is proposed, Oculatella subterranea.
Effects of a simulated martian UV flux on the cyanobacterium, Chroococcidiopsis sp. 029.
TLDR
Under the intense martian UV flux the morphological signatures of life can persist even after viability, enzymatic activity, and pigmentation have been destroyed, showing implications for the survival of diverse microbial contaminants dispersed during the course of human exploratory class missions on the surface of Mars.
Sustainable life support on Mars – the potential roles of cyanobacteria
TLDR
Insights are given into how and why cyanobacteria could play a role in the development of self-sustainable manned outposts on Mars, and a wide range of life-support biological processes based on Martian resources.
Subcellular integrities in Chroococcidiopsis sp. CCMEE 029 survivors after prolonged desiccation revealed by molecular probes and genome stability assays
TLDR
The co-occurrence of live and dead cells within dried aggregates of Chroococcidiopsis confirms that desiccation resistance is not a simple process and that subtle modifications to the cellular milieu are required to dry without dying.
Gene Transfer to the Desiccation-Tolerant CyanobacteriumChroococcidiopsis
TLDR
This report provides the first evidence that pDU1 replicons can be maintained in cyanobacteria other than Nostoc and Anabaena, and suggests that desert strains 057, 123, 171, and 029 are distinct from the type species strain Chroococcidiopsis thermalis PCC 7203.
A Method for DNA Extraction from the Desert Cyanobacterium Chroococcidiopsis and Its Application to Identification of ftsZ
TLDR
This method permitted the first molecular approach to the study of Chroococcidiopsis, and a 570-bp fragment of the geneftsZ was cloned and sequenced.
