Glycine betaine biosynthesized from glycine provides an osmolyte for cell growth and spore germination during osmotic stress in Myxococcus xanthus.

چکیده
Glycine sarcosine methyltransferase (Gsm) and sarcosine dimethylglycine methyltransferase (Sdm) catalyze glycine betaine synthesis from glycine. Disruption of the M. xanthus gsmA (MXAN 7068) or sdmA (MXAN 3190) gene, encoding Gsm or Sdm homologue proteins, respectively, generated mutants that exhibited a longer lag period of growth and delayed spore germination under osmostress.

An adenylyl cyclase, CyaA, of Myxococcus xanthus functions in signal transduction during osmotic stress.
An adenylyl cyclase gene (cyaA) present upstream of an osmosensor protein gene (mokA) was isolated from Myxococcus xanthus. cyaA encoded a polypeptide of 843 amino acids with a predicted molecular mass of 91,187 Da. The predicted cyaA gene product had structural similarity to the receptor-type adenylyl cyclases that are composed of an amino-terminal sensor domain and a carboxy-terminal catalyti...

In many plants, glycine betaine acts as an osmotic protectant and osmolyte. But some plants, such as the tomato, are not able to synthesize and accumulate this osmolyte. This study was designed to investigate the effect of exogenous application of glycine betaine in reducing drought stress in tomato plants. Water stress in three levels (0, 3 days and 5 days without irrigation) and glycine betai...

Dianthus barbatus is an important ornamental bedding plant in temperate regions with traditional medicinal applications. Water shortage and drought stress are major limitations for landscape development and plant medicine production. Callogenesis is the key step for modern plant breeding techniques and in vitro drought stress study defines the mechanisms of plant response to stress. Therefore t...
متن کاملThree transporters mediate uptake of glycine betaine and carnitine by Listeria monocytogenes in response to hyperosmotic stress.
The uptake and accumulation of the potent osmolytes glycine betaine and carnitine enable the food-borne pathogen Listeria monocytogenes to proliferate in environments of elevated osmotic stress, often rendering salt-based food preservation inadequate. To date, three osmolyte transport systems are known to operate in L. monocytogenes: glycine betaine porter I (BetL), glycine betaine porter II (G...
متن کاملContribution of the cyclic nucleotide phosphodiesterases PdeA and PdeB to adaptation of Myxococcus xanthus cells to osmotic or high-temperature stress.
A tBLASTn search of the Myxococcus xanthus genome database at The Institute for Genomic Research (TIGR) identified three genes (pdeA, pdeB, and pdeC) that encode proteins homologous to 3',5'-cyclic nucleotide phosphodiesterase. pdeA, pdeB, and pdeC mutants, constructed by replacing a part of the gene with the kanamycin or tetracycline resistance gene, showed normal growth, development, and germ...
