CONCLUSIONS
Casbene is a precursor to phorbol esters and down-regulating casbene synthase effectively reduces phorbol ester biosynthesis. Seed-specific reduction of phorbol ester (PE) helps develop Jatropha seed cake for animal nutrition. Phorbol esters (PEs) are diterpenoids present in some

Casbene is a macrocyclic diterpene hydrocarbon that is produced in young castor bean (Ricinus communis L.) seedlings after they are exposed to Rhizopus stolonifer or other fungi. The activities of enzymes that participate in casbene biosynthesis were measured in cell-free extracts of 67-hour castor

A castor bean cDNA library has been constructed in the expression vector lambda gt11. Screening of 30,000 plaques with antibodies against casbene synthetase yielded six positive clones, from which three purified clones were obtained after sequential screening. The cDNA inserts in these clones ranged
