Purification and Biochemical Characterisation of Ricin from Castor Seeds
Ricin is a highly toxic plant toxin of Ricinus comtnunis seeds, commonly known as castor seeds. The toxin was extracted and purified using affinity and size exclusion chromatography. The purity of ricin was evaluated by the sodium dodecylsulphate-polyacrylamide gel electrophoresis. Purified ricin gives a single band under non-reduced condition and two bands under reduced condition. The molecula...

15 صفحه اولSynthesis of the crystalloid protein complex in vivo in the endosperm of developing castor bean seeds.
The synthesis of subunit polypeptides of the crystalloid protein complex has been examined in endosperm from developing castor bean (Ricinus communis L. cv Hale) seeds. Pulse-label and -chase studies in vivo have shown that synthesis initially involves the formation of high molecular weight precursors (50 to 60 kilodaltons) comprising peptide-linked acidic and basic polypeptides. Precursor proc...

متن کاملDifferential Expression Patterns of Lipid Genes in Developing Seeds of Castor Bean (ricinus Communis L.)
Castor bean (Ricinus communis L.) is one of the most important non-edible oilseed crops. Characterization of seed development and lipid accumulation from female flowers pollinated to mature seeds has been carried out. The temporal expression patterns of 65 lipid genes involved in fatty acid and triacylglycerol biosynthesis using the semi-quantitative RT-PCR technique were also investigated. The...
