Plant programmed cell death

The situation with the domain families of the ubiquitin-mediated pathway contrasts with the domain families that function in animal and plant programmed cell death, or apoptosis. As reviewed elsewhere (Ara-vind et al., 1999b), a few domains in eukaryotic apoptotic proteins have prokaryotic homologs, including the cysteine protease family of caspases...

Knowles and Milner, 2000). Furthermore, these compounds are thought to be involved in the inhibition of certain cytochrome P-450 enzyme-dependent bioactivations of procarcinogens and protoxicants (Brady et al., 1991), as well as to increase levels of glutathione-S-transferase (GST), an enzyme of particular importance in the detoxification of xenobiotics in the body (Wilce and Parker, 1994). Most recently, the ability of various plants and plant extracts to influence apoptosis, or programmed cell death, in cancerous cells in an attempt to arrest their proliferation, has been the topic of much research. Allicin has been shown to induce apoptosis in a variety of cell lines, including human hepatocellular carcinoma cells (KIM-1) and human lymphoid leukemia (MOLT-4B) cells (Thatte et al., 2000).

The processes connected with the hypersensitive response give rise to a localized necrosis which may be regarded as a special kind of programmed cell death. In this way the spreading of the pathogen to other parts of the host plant is prevented. The hypersensitive response is initiated by a number of compounds which are collectively designated as elicitors. Compounds of different chemical classes such as proteins, carbohydrates, lipids and certain polyenoic fatty acids have been identified as elicitors.
