Studies of the Amino Acid Sequence of Plastocyanin from Rumex obtusifolius (Broad-Leaved Dock)
Plastocyanins are low-molecular-weight cuproproteins, which occur in the chloroplasts of plants and algae. The exact biological function of the protein remains uncertain, but is probably associated with photosynthetic electron transport (Gregory, 1971). The small size and blue colour of the protein simplify the purification of plastocyanin, and studies with a number of species have been reporte...
متن کاملheterogeneity within the orientalist discourse: representation of the orient in womens travelogues and mens paintings
from 1950s onward, new theories and critical approaches burgeoned across humanities. these theories were context-oriented; as a result, the analysis of discursive practices gained significance. thus, social, political, historical and cultural discourses that have been hitherto marginalized and considered inferior to literary texts, were introduced as important texts to be analyzed by critics. o...
A New Anthraquinone Isolated from Rumex Obtusifolius
In this research we studied Rumex obtusifolius (Polygonaceae) along with other plants used in traditional medicine in relation to the chemical reaction FBIT (Ferriprotoporphyrine Biocrystallization Inhibition Test) which may provide information on a possible action mechanism for presumed antimalarial plants. According to folk medicine Rumex obtusifolius has a pronounced detoxifying effect on th...
متن کاملMineral Composition and Nutritive Value of Some Common Pasture Weeds
Organic dairy farmers often introduce alternative pasture species, such as chicory (Cichorium intybus) and narrow-leaved plantain (Plantago lanceolata), to their swards because of their higher mineral contents, yet they are concerned about the presence of weed species such as docks (Rumex spp.) and dandelion (Taraxacum officinale). The mineral content and nutritive value of both desired and les...
متن کاملAllelopathic effects of Rumex obtusifolius leaf extracts against native grassland species
In perennial grasslands R. obtusifolius (broad-leaved dock) is often surrounded by certain plant species. Thus, it is hypothesized for the current study that Rumex can affect their neighbouring plant species by allelopathic interactions. To test this hypothesis, in a series of laboratory and field experiments aqueous extracts of green R. obtusifolius leaves were sprayed on seeds of 14 herbaceou...
