چکیده

The major storage protein fraction, globulin-1 protein, of French bean (Phaseolus vulgaris L.) was analyzed by two-dimensional electrophoresis. The protein pattern suggested a more complex system for globulin-1 protein than the model of three polypeptides, alpha, beta, and gamma, differing in molecular weight. Isoelectrofocusing analyses of the individual proteins showed that each exhibited charge microheterogeneity over a similar pH range. Isoelectrofocusing banding patterns may help to understand the relationships between the globulin-1 polypeptide subunits.

The effect of priming on physiological and biochemical traits of French bean (Phaseolus vulgaris) under cobalt chloride stress

Extended Abstract Introduction: The germination stage ensures the durability, establishment, and final yield of plants.  The final density of plants per unit area is resulted when the planted seeds germinate fully and with adequate rate. Plants mainly undergo abiotic stresses that are a considerable constraint for agricultural production worldwide. Seed priming is one of the simplest and cheap...

Protein Synthesis and Accumulation in Bean Cotyledons during Growth.

Analysis of total protein, of specific proteins by gel electrophoresis and immunoelectrophoresis, and of protein synthetic activity in vitro confirmed that intense protein synthesis and accumulation occurred as the French bean (Phaseolus vulgaris L). seed grew from 12 to 20 millimeters. These techniques showed that there was no globulin-1 (G1) fraction (requiring high salt for solubility) prese...

This study investigated the subcellular location of mung bean (Vigna radiata) 8S globulin in transient expression systems as well as in tobacco (Nicotiana tabacum) BY-2 cells and different tissues from a transgenic Arabidopsis (Arabidopsis thaliana) line stably expressing this storage globulin. When transiently expressed in protoplasts from both BY-2 cells and Arabidopsis suspension cultured ce...

Grouping of bread wheat cultivars by seed storage proteins. Sonia Kahrizi1, Mohammad Sedghi2* and Omid Sofalian2

To determine seed storage protein banding patterns in some bread wheat cultivars and the similarity of banding patterns among different cultivars, an experiment based on seed storage protein electrophoresis (albumin and globulin) was performed. Water and salt soluble proteins were extracted in sixteen wheat cultivars using polyacrylamide gel electrophoresis and banding pattern was obtained. Stu...
