Cellulase and Abscission in the Red Kidney Bean (Phaseolus vulgaris).
Cellulase (beta-1, 4-glucan-glucanohydrolase EC 3.2.1.4) activity in the abscission zone of red kidney bean (Phaseolus vulgaris) was previously shown to exist in at least two different molecular forms. The form of the enzyme which has an isoelectric point of 4.5 is present in both abscising and nonabscising tissue and requires grinding for extraction. Another form of the enzyme which has an iso...
متن کاملSynthesis of Cellulase during Abscission of Phaseolus vulgaris Leaf Explants.
When abscission in leaf explants from Phaseolus vulgaris, cultivar Red Kidney, was allowed to proceed while the explants were in (2)H(2)O, a 1.25% increase in the buoyant density of cellulase in a cesium chloride gradient was observed. These data indicate that the increase in cellulase activity during abscission is a result of the synthesis of new protein. Two differentially soluble forms of ce...
متن کاملAn antifungal peptide from Phaseolus vulgaris cv. brown kidney bean.
A 5.4-kDa antifungal peptide, with an N-terminal sequence highly homologous to defensins and inhibitory activity against Mycosphaerella arachidicola (IC(50)= 3 μM), Setospaeria turcica and Bipolaris maydis, was isolated from the seeds of Phaseolus vulgaris cv. brown kidney bean. The peptide was purified by employing a protocol that entailed adsorption on Affi-gel blue gel and Mono S and finally...
متن کاملFortification of white flat bread with sprouted red kidney bean (Phaseolus vulgaris).
BACKGROUND Protein quantity in diet including the digestibility and bioavailability of protein is of importance to eradicate undernutrition in developing countries. Bread protein is an incomplete source as it lacks an essential amino acid lysine. When they are combined with other plant foods like pulses and legumes, they become a complete source of protein. Since bread is most common staple foo...
متن کاملGenetic Diversity and Nutritional Components Evaluation of Bangladeshi Germplasms of Kidney Bean (Phaseolus vulgaris L.)
Considering the crucial focus on plant developments as high yielding, protein, and disease-resistant varieties, in this study, the genetic diversity and nutritional traits of available kidney bean germplasms found in Bangladesh have been evaluated based on seventeen quantitative and six nutritional traits. Analysis of genotypic, phenotypic variance and covariance showed that higher environmenta...
