Antiarthritic activity of Cynodon dactylon (L.) Pers.
Cynodon dactylon (L.) (Poaceae) is traditionally used herb to treat fevers, skin diseases and rheumatic affections. The ethanolic extract of C. dactylon was found to be safe at all the dose levels (100, 200 and 400 mg/kg, orally) and there was no mortality up to the dose of 5000 mg/kg of extract when administered orally. C. dactylon showed significant antiarthritic activity against Freund's com...
متن کاملAnalysis of Natural Variation in Bermudagrass (Cynodon dactylon) Reveals Physiological Responses Underlying Drought Tolerance
Bermudagrass (Cynodon dactylon) is a widely used warm-season turfgrass and one of the most drought tolerant species. Dissecting the natural variation in drought tolerance and physiological responses will bring us powerful basis and novel insight for plant breeding. In the present study, we evaluated the natural variation of drought tolerance among nine bermudagrass varieties by measuring physio...
متن کاملRegulation of acetohydroxy acid synthase in streptomycin-dependent Escherichia coli.
Growth of streptomycin-dependent mutants of Escherichia coli K-12 was insensitive to valine when dihydrostreptomycin was present in a nonlimiting concentration in glucose-salts medium. Acetohydroxy acid synthase was derepressed under these conditions, owing to relaxation of catabolite repression. Valine sensitivity and catabolite repression were restored when streptomycin-dependent E. coli K-12...
متن کاملSubunit association in acetohydroxy acid synthase isozyme III.
Acetohydroxy acid synthase isozyme III (AHAS III) from Escherichia coli is composed of large and small subunits (encoded by the genes ilvI and ilvH) in an alpha 2 beta 2 structure. The large (61-kDa) subunit apparently contains the catalytic machinery of the enzyme, while the small (17-kDa) subunit is required for specific stabilization of the active conformation of the large subunit as well as...
متن کاملContrasting Changes Caused by Drought and Submergence Stresses in Bermudagrass (Cynodon dactylon)
In this study, we investigated the mechanisms by which bermudagrass withstands the drought and submergence stresses through physiological, proteomic and metabolomic approaches. The results showed that significant physiological changes were observed after drought treatment, while only slight changes after submergence treatment, including compatible solute contents, ROS levels and antioxidant enz...
