TL;DR: The kinetics of glycine betaine transport suggest that the two transport systems are indistinguishable in terms of affinity for betaine and may be the same, and a cold-activated transport system is a novel observation and has intriguing implications concerning the physical state of the cell membrane at low temperature.

TL;DR: It was demonstrated that glycine betaine, a powerful osmotic stress protectant, participates in osmoregulation in this organism and growth rates of cultures in 0.7 M NaCl were increased more than threefold, and enhancement of growth could be observed with as little as 10 microM glycine Betaine or precursor added to the medium.

TL;DR: This work used natural-abundance 13C nuclear magnetic resonance to identify all organic solutes that accumulate to significant levels in Rhizobium meliloti and led to the discovery of a new dipeptide, N-acetylglutaminyl glutamine amide (NAGGN), which is accumulated during osmotic stress.

TL;DR: The full-length cDNA sequence (P93622_VITVI) of polyphenol oxidase (PPO) cDNA from grape Vitis vinifera L., cv Grenache, was found to encode a translated protein of 607 amino acids with an expected molecular weight of ca.

TL;DR: Kinetic and steady-state compatible solute accumulation data together with growth rate experiments demonstrated that under cold stress glycine betaine transport is primarily mediated by Gbu and that Gbu-mediated betaine uptake results in significant growth stimulation of chill-stressed cells.
