In 2009 a National Security Science and Technology grant was awarded to the Human Protection and Performance Division for the investigation of several forensic aspects of the castor bean plant Ricinus communis. A major focus of this grant was to understand the chemical composition of the seeds, and to ascertain if these differences could be used for provenance classification. This technical rep...

castor (ricinus communis l.) is one of the most ancient medicinal oil crops in the world. it has been vastly distributed in different parts of iran. in the present study, the inter simple sequence repeat (issr) markers were used to evaluate the molecular genetic diversity among and within 12 castor accessions collected from 7 regions of iran. totally, 16 issr primers amplified 166 loci, of whic...

Ricinus communis L. (Euphorbiaceae, Acalyphoideae) is a highly variable species known as the castor oil plant. This study aimed to describe R. using several methodologies, such vegetative morphometry, leaf surface ultrastructure, soil analysis, and gas chromatography-mass spectrometry (GC-MS) understand diversity of this species. The morphological analysis revealed that some samples had purple ...
