Lateral Gene Transfer of Dissimilatory (Bi)Sulfite Reductase Revisited
TLDR
It is demonstrated that the dissimilatory (bi)sulfite reductase genes (dsrAB) of Desulfobacula toluolica were vertically inherited. Expand
Origins and diversification of sulfate-respiring microorganisms
TLDR
These studies suggest at least two major lateral transfer events during the early diversification of sulfate respiring microorganisms and suggest that the habitat range and evolutionary diversity of this key functional group of organisms is greater than now appreciated. Expand
Functional marker genes for identification of sulfate-reducing prokaryotes.
TLDR
This chapter provides detailed protocols for the application of these functional marker molecules for SRP diversity surveys in the environment and describes a novel gel retardation-based technique, suitable for fingerprinting of the approximately 1.9-kb-large dsrAB polymerase chain reaction amplification products, which efficiently increases the chance of retrieving rare and novel dSRAB sequence types from environmental samples.

Endosymbiotic sulphate-reducing and sulphide-oxidizing bacteria in an oligochaete worm
TLDR
It is shown that in the gutless marine oligochaete Olavius algarvensis, endosymbiotic sulphate-reducing bacteria produce sulphide that can serve as an energy source for sulphide-oxidizing symbionts of the host. Expand
Genome structure of a virus infecting the marine brown alga Ectocarpus siliculosus.
TLDR
It is proposed that the native Ectocarpus virus genome is a circular DNA molecule whose double strand is interrupted by single-stranded regions that produces large linear as well as fragmented DNA. Expand
Salt tolerance of potato (Solanum tuberosum L. var. Desirée) plants depends on light intensity and air humidity
TLDR
Plant growth at high air humidity and at low light can be used as a tool to study NaCl-induced stress in glycophytes under laboratory conditions, without concomitant metabolic and genetic alterations induced by oxidative stress. Expand
Single-stranded regions in the genome of the Ectocarpus siliculosus virus.
TLDR
The double-stranded DNA genome of the Ectocarpus siliculosus virus, EsV, is interrupted by numerous single-stranding gaps and may contain a few extended single-Stranded regions at fixed sites in addition to numerous single thestranded regions probably occurring at random and varying sites. Expand
Leucine synthesis in chloroplasts: Leucine/isoleucine aminotransferase and valine aminotransferase are different enzymes in spinach chloroplasts
TLDR
It is demonstrated that the complete synthesis of leucine is localized in chloroplasts and the problem of pathways competing for the same introductory substrates, acetyl-CoA and 2-oxoisovalerate, is discussed. Expand
Localisation of Aluminium in Root Tips of Zea mays and Vicia faba
TLDR
Monocot species and dicot species differ widely in the composition of their cell walls, namely in the pectin content, and thus in potential Al-binding sites, and by far the highest Al concentrations were always measured in the cell wall. Expand
Formation and role of glycine betaine in the moderate halophile Vibrio costicola
TLDR
The moderate halophile Vibrio costicola, growing on a chemically-defined medium, transformed choline into glycine betaine (betaine) by the membrane-bound enzyme choline dehydrogenase and the cytoplasmic enzyme betainal (Betaine aldehyde) dehydrogen enzyme, which is important for some of the adaptations to high salt concentration by V. costicolas.
