trichosanthes truncata/ニコチン

Trichosanthin (TCS) is an antiviral plant defense protein, classified as a type-I ribosome-inactivating protein, found in the root tuber and leaves of the medicinal plant Trichosanthes kirilowii. It is processed from a larger precursor protein, containing a 23 amino acid amino (N)-terminal sequence

In August of 2002, cucumber (Cucumis sativus L. cv. Himangi) plants grown in commercial fields in Pune, western Maharashtra, India, exhibited chlorotic spots, veinal chlorosis, mosaic, blister formation and shoestring symptoms on leaves, stunted growth, and distortion of fruits. Incidence of virus

alpha-Trichosanthin, a eukaryotic ribosome-inactivating protein from Trichosanthes kirilowii, inhibits the replication of the human immunodeficiency virus (HIV) in vitro. The alpha-trichosanthin gene was placed under the transcriptional control of a tobamovirus subgenomic promoter in a plant RNA

Root extract of Boerhaavia diffusa L. induced systemic resistance in tobacco against Tobacco mosaic virus. A 30 kDa protein was isolated as the active component, called BDP-30 on the basis of the molecular weight and source plant. BDP-30, a glycoprotein, was found to be temperature and protease

Citrus mosaic disease, a potential threat to citrus production throughout India, is currently an important disease in the southern and northeastern states (2). The reported incidence of the disease ranges from 10 to 77% (K. Gopal, G. S. Aparna, M. Sreenivasuluk, K. V. Subbaiah, and A. R. K. Rao,

Programmed cell death (apoptosis), a form of cell death, described by Kerr and Wyllie some 20 years ago, has generated considerable interest in recent years. The mechanisms by which this mode of cell death (seen both in animal and plant cells), takes place have been examined in detail. Extracellular
