Antirrhinum majus, Flavonoid Biosynthesis, Flavanone Oxidase, Apigenin, Luteolin Enzyme preparations from flowers of Antirrhinum majus catalysed the oxidation of naringenin to apigenin and of eriodictyol to luteolin. Enzyme activity was found to be localized in the microsomal fraction. The reaction required NADPH as cofactor and had a pH optimum of about 7.0. The NADPH-dependent microsomal enzy...

Plants grow under climatic changing conditions that cause modifications in vegetative and reproductive development. The degree of changes in organ development i.e. its phenotypic plasticity seems to be determined by the organ identity and the type of environmental cue. We used intraspecific competition and found that Antirrhinum majus behaves as a decoupled species for lateral organ size and nu...

Chelidonium majus is a well-known source of biologically active compounds. Most them are alkaloids, which used in researches and for tradition medicine. In this study, we explored the influence C. crude total extract onto blood coagulation system vitro, primary secondary hemostasis. Aim. To study process. Methods. Turbidimetry plasma, APTT test with chromogenic substrates, platelet aggregation ...

Drought, salinization and heavy metal pollution of soils are main stress factors with an increasing impact on the deterioration soil quality, yield crop quality. Seed priming shows good results in improving seed germination, seedling growth plant development. Proline (Pro) metyl jasmonate (MeJA) show stimulating activity help plants overcome stress. The study investigated effect Pro, MeJA hydro...

monthly nurse within six months. I had some difficulty in persuading her not to begin work earlier, but I was naturally anxious that her leg should be thoroughly well first, and she has had no trouble with it since. I mention this preliminary illness as it has some bearing, as we shall see, on subsequent developments. In 1921, the patient had a fall on her coccyx which shook her considerably, a...
