2. Classification of Elicitors
According to Radman et al. elicitors are classified
as physical or chemical. On the basis of nature
elicitors can be devided into two types Biotic and
Abiotic. The biotic elicitors have biological
origin, derived from the pathogen or from the
plant itself while abiotic elicitors have not a
biological origin and are grouped in physical
factor and chemical compounds. The first biotic
elicitors was discovered in 1968.
Further on the basis of plant elicitor interaction it
may be classified into race specific and general
elicitors[3,4].
Elicitation of plant cell culture system may be
promising as it showed favorable results in
fermentation of antibiotics and many other
fermented products. Though, elicitation enhances
secondary metabolism in plants or plant cells in
vitro. This provides an opportunity for intensive
research in the field of biosciences for
exploitation of plant cells for the production of
secondary metabolites. Tabel 1 represents the
classification of elicitors.
