In a search for biomarkers of health in whale sharks and as exploration of metabolomics as a modern tool for understanding animal physiology, the metabolite composition of serum in six whale sharks (Rhincodon typus) from an aquarium collection was explored using (1)H nuclear magnetic resonance (NMR) spectroscopy and direct analysis in real time (DART) mass spectrometry (MS). Principal component...
Drought stress causes considerable yield losses in agriculture and receives high attention in current sunflower breeding programs. For this study, an in vitro system based on MS media (Murashige and Skoog, 1962) supplemented with polyethylene glycol 6000 (Korell, 1997) was established to examine sunflower (Helianthus annuus L.) seedlings under artificial drought stress conditions. The objective...
Synthesis of the osmolyte glucosylglycerol (GG) in the marine cyanobacterium Synechococcus sp. strain PCC 7002 was characterized. The ggpS gene, which encodes the key enzyme (GG-phosphate synthase [GgpS]) in GG biosynthesis, was cloned by using PCR. A 2,030-bp DNA sequence which contained one open reading frame (ORF) was obtained. The protein deduced from this ORF exhibited 85% similarity to th...
ATP-binding cassette transporters from several rhizobia and Salmonella enterica serovar Typhimurium, but not secondarily coupled systems, were inhibited by high concentrations (100 to 500 mM) of various osmolytes, an effect reversed by the removal of the osmolyte. ABC systems were also inactivated in isolated pea bacteroids, probably due to the obligatory use of high-osmolarity isolation media....
