To study the function of bean rust haustoria either the host, Phaseolus vulgaris, or the parasite, Uromyces phaseoli, were labeled with 3H-lysine. 24h and 48 h after inoculation samples of the infected leaves were taken and processed for electronmicroscopic autoradiography. When the host was labeled, silver grain densities over the structures of host and parasite were compared. Very low grain d...

We have confirmed here that the seeds of the common bean (Phaseolus vulgaris, L.) do not support development of the bruchid Callosobruchus maculatus (F.), a pest of cowpea [Vigna unguiculata (L.) Walp] seeds. Analysis of the testa (seed coat) of the bean suggested that neither thickness nor the levels of compounds such as tannic acid, tannins, or HCN are important for the resistance. On the oth...

Human Tamm-Horsfall glycoprotein inhibits lymphocyte transformation induced by leucoagglutinin and haemagglutinin from Phaseolus vulgaris (red kidney bean). The glycoprotein interacts with the two lectins, giving insoluble precipitates. The interaction with leucoagglutinin is highly specific, and the shape of the precipitin curve is that of an antigen-antibody reaction; precipitation is specifi...

BACKGROUND Phaseolus vulgaris is one of the most extensively studied model legumes in the world. The P. vulgaris genome sequence is available; therefore, the need for an efficient and rapid transformation system is more imperative than ever. The functional characterization of P. vulgaris genes is impeded chiefly due to the non-amenable nature of Phaseolus sp. to stable genetic transformation. T...

Soil solution pH can affect the response of common bean (Phaseolus vulgaris L.) to mesotrione residues | Laura Pismarović, Ana Milanović-Litre, Kristina Kljak, Boris Lazarević, Maja Šćepanović Agricultural Journals

Consumption of Phaseolus vulgaris bean species such as pinto, black, navy or kidney may be beneficial in the prevention and treatment of chronic diseases. In particular, conditions that are promoted by increased glycaemic stress (hyperglycaemia and hyperinsulinaemia) including diabetes, CVD and cancer seem to be reduced in individuals who eat more of these beans. The present paper discusses the...
