Enigmatic, ultrasmall, uncultivated Archaea.
Metagenomics has provided access to genomes of as yet uncultivated microorganisms in natural environments, yet there are gaps in our knowledge-particularly for Archaea-that occur at relatively low abundance and in extreme environments. Ultrasmall cells (<500 nm in diameter) from lineages without cultivated representatives that branch near the crenarchaeal/euryarchaeal divide have been detected ...
متن کامل“Altiarchaeales”: Uncultivated Archaea from the Subsurface
Due to the limited cultivability of the vast majority of microorganisms, researchers have applied environmental genomics and other state-of-the-art technologies to gain insights into the biology of uncultivated Archaea and bacteria in their natural biotope. In this review, we summarize the scientific findings on a recently proposed order-level lineage of uncultivated Archaea called Altiarchaeal...
متن کاملGrappling archaea: ultrastructural analyses of an uncultivated, cold-loving archaeon, and its biofilm
Similarly to Bacteria, Archaea are microorganisms that interact with their surrounding environment in a versatile manner. To date, interactions based on cellular structure and surface appendages have mainly been documented using model systems of cultivable archaea under laboratory conditions. Here, we report on the microbial interactions and ultrastructural features of the uncultivated SM1 Eury...
متن کاملA novel three-unit tRNA splicing endonuclease found in ultrasmall Archaea possesses broad substrate specificity
tRNA splicing endonucleases, essential enzymes found in Archaea and Eukaryotes, are involved in the processing of pre-tRNA molecules. In Archaea, three types of splicing endonuclease [homotetrameric: α(4), homodimeric: α(2), and heterotetrameric: (αβ)(2)] have been identified, each representing different substrate specificity during the tRNA intron cleavage. Here, we discovered a fourth type of...
متن کامل[An enigmatic eye in an enigmatic bust].
have read with interest the article published in the iconoraphic section of this Journal by Drs. Diez-Lage and González nd titled The enigmatic eye of Nefertiti.1 After publishing a eview on the topic in the February issue of the British Journal f Ophthalmology,2 I would like to make a few comments. Queen Nefertiti (c. 1370–1330 AC) was the Great Royal Wife f Akhenaton (Amenhotep or Amenophis I...
