The enzyme hydrolysing N-benzoyl-D,L-arginine-p-nitroanilide (BAPA). is isolated from vetch seedlings and 1600-fold purified by means of chromatography on DEAE-cellulose, hdroxyapatite and gel filtration through Sephadex G-100. The preparation is chromatographically homogenous, but disc
Some guanidino compounds have been found to inhibit spontaneous mammary tumourigenesis in mice. In the present study, the effects of chronic treatment with Gold Banded Lily (Lilium auratum LindI) or Chinese Milk Vetch (Astragalus sinicus L), which contains L-arginine or L-canavanine, on spontaneous
In vitro binding experiments were carried out using (32)P-labeled cells of the virulent Agrobacterium tumefaciens strain B6 and Datura innoxia cells from suspension culture. Binding kinetics showed that adherence of bacteria to Datura cells increased gradually during the first 60 minutes and
The parasitic plant broomrape is entirely dependent on its host for reduced carbon and nitrogen and is also susceptible to inhibition by glyphosate that is translocated to the parasite through a host. Studies were conducted to examine the effect of broomrape parasitism on amino acid concentrations
Two-component signal transduction systems (TCS) are a main strategy used by bacteria to sense and adapt to changes in their environment. In the legume symbiont Rhizobium leguminosarum biovar viciae VF39, mutation of chvG, a histidine kinase, caused a number of pleiotropic phenotypes. ChvG mutants
ractText>Common vetch (Vicia sativa L.) is an important self-pollinating annual forage legume and is of interest for drought prone regions as a protein source to feed livestock and human consumption. However, the development and production of common vetch are negatively affected by drought
