Exogenous low-dose hydrogen peroxide enhances drought tolerance of soybean (glycine max l.) through inducing antıoxidant system
(Akademiai Kiado Zrt, 2016)
Hydrogen peroxide (H2O2) functions as a signal molecule in plants under abiotic and biotic stress. in this study, the role of exogenous H2O2 in improving drought tolerance in two soybean cultivars (Glycine max L. Merrill) ...
Microwave-assisted and conventional synthesis of novel antimicrobial 1,2,4-triazole derivatives containing nalidixic acid skeleton
(Walter de Gruyter Gmbh, 2016)
Carbothioamides 4a,b, obtained from nalidixic acid, were converted to the corresponding 1,3-thiazolidine derivatives 5a,b by cyclocondensation with 2-bromo-1-(4-chlorophenyl) ethanone. Treatment of 4a,b with base afforded ...
