Halobacillus trueperi accumulates glycine betaine under condition of high osmolarity. A fragment of the glycine betaine transporter betH gene was obtained from the genome of H. trueperi with degenerate primers. Through Southern blot hybridization and inverse PCR, a 5.1 kb EcoRI fragment containing
Assessing metabolomic alterations in age-related macular degeneration (AMD) can provide insight on its pathogenesis. We compared the metabolomic profiles of the aqueous humor between wet AMD patients (n=26) and age- and sex-matched patients undergoing cataract surgery without AMD as controls (n=20).
The P2 promoter of proP, encoding a transporter for proline and glycine betaine in Escherichia coli, is a unique paradigm, where master regulators of different growth stages, Fis and sigma(S) (RpoS), collaborate to achieve promoter activation. It is also the only case described where Fis functions
The aim of this manuscript was to investigate the role of calcium compounds, viz., Ca(OH)2, Ca(NO3)2, and CaCl2 (each used at 0.3 mM and 0.5 mM concentration) as seed priming agents to ameliorate fluoride toxicity in rice. The stressed seedlings exhibited
