Phytoalexins are secreted by plants in response to fungal reaction. These
compounds are generally
А.Proteins
B.Glycoproteins
C.Phenolic compounds
D.Lipids
Solution
Phytoalexins are antifungal or antibacterial mixes orchestrated in plants under burdens, parasitic assault, or elicitor treatment. Glyceollins are a sort of isoflavonoid phytoalexins interesting to soybeans and integrated by soy plants under focused conditions, for example, parasitic contamination.
Complete answer:
-Phytoalexins are low atomic weight, phenolic, antimicrobial mixes integrated and collected in plants in light of outward pressure, for example, microbial contamination. Phytoalexins have antifungal properties and are regularly microorganisms explicit in their toxicity. e.g., medicarpin, rishitin, camalexin. Phytoalexins are phenolic compounds produced in the host cell for defense in response to fungal infection . These chemicals inhibit growth of the parasite In this manner.
Additional Information:
- The proteins in plant cells are frequently just found at one specific end, nonetheless; they have a direction.
- Glycoproteins are proteins which contain oligosaccharide chains (glycans) covalently joined to amino corrosive side-chains. The starch is appended to the protein in a cotranslational or posttranslational modification.
- Lipids are usually found in plant seeds, according to Cyber Lipid. The majority of this fat is found in the embryo and endosperm, which makes sense, since the endosperm is the food source of the plant embryo as it grows.So these are incorrect options.
Hence, The right answer is option C.
Note: Phytoalexins produced in plants act as toxins to the attacking organism.They may penetrate the cell wall, postpone development, disturb digestion or forestall proliferation of the microorganism . Their significance in plant protection is demonstrated by an expansion in weakness of plant tissue to contamination when phytoalexin biosynthesis is restrained.
