Production of Alkaloids by Ergot (Claviceps fusiformis Lov.) on Pennisetum typhoides (Burm.) Stapf and Hubb. in Vitro
Ergot disease of pearl millet [Pennisetum typhoides (Burm.) Stapf and Hubb.] caused by Claviceps fusiformis Lov. results in the formation of sclerotia in place of normal grains. Most Claviceps sp. and strains, whether living as parasites or grown in axenic culture show growth phase, transition period, and finally alkaloid producing phase (idio-phase). Sclerotia are reported to contain clavine group of alkaloids. Like other indole alkaloids, ergot alkaloids are derived in part from tryptophan and methyl group of methionine. The ergot poisoning which may result from consumption of ergotted grains, is characterized by symptoms such as nausea, vomiting, diarrhoea, giddiness, and even death of human beings and livestock. Several investigations have been undertaken on the estimation and identification of alkaloids produced by Claviceps fusiformis in vivo and in axenic cultures [1–5].
