- Preformed
antimicrobial compounds are called phytoanticipins
- Phytoanticipins are
unique as they are preformed, rather than being synthesized from
remote precursors after pathogen infection (phytoalexins)
- Phytoanticipins has 2
classes constitutive: saponins (glycosylated antimicrobials)
inactive precursors processed after tissue damage or pathogen attack
(cyanogenic glycosides and glucosinolates)
- Fruits contain
secondary metabolites with antifungal properties, called
phytoanticipins..
- Phytoalexins and
phytoanticipins
serve both structural and metabolic functions in disease resistance
- Phytoalexins and
phytoanticipins can be as low molecular weight antimicrobial
compounds that are synthesized by plants. The major function of PAL
is to catalyze phytoalexins and phytoanticipins production and
thereby reduce disease severity
- Phytoanticipins are
high energy and carbon consuming and exhibit fitness cost under
natural conditions, but recognized as the first line of chemical
defense that potential pathogens have to overcome.
- Phytoanticipins seem
adequate for therapeutic use.
- Phytoanticipins are
secondary metabolites produced by fungi and plants
- Phytoanticipins are
preformed
antifungal secondary metabolites present in the healthy plants. For
example, glucosinolates are stored in vacuoles
- The ultimate objective
of investigations studying the relevance of phytoanticipins and
phytoalexins in the plant defence response is to develop
biotechnological applications in crop protection. Some of the above
described phytoalexins provide a potentially interesting weapon to
be used in agricultural techniques.
