Question

Desert plants are covered with chitin why ??

Answer 1

Chitin is a good inducer of plant defense mechanisms for controlling diseases. It has also been assessed as a fertilizer that can improve overall crop yields.Although plants lack chitin, they do secrete chitin-degrading enzymes. During fungal infection, plant cells secrete chitinases that release chitin fragments (chitooligosaccharides or chitin oligomers) from fungal cell walls that can act as an elicitor to induce plant innate immunity against the invading pathogen.Chitin is a promising soil amendment for improving soil quality, plant growth, and plant resilience.Chitin. Chitin is a major constituent of the exoskeleton, or external skeleton, of many arthropods such as insects, spiders, and crustaceans. Exoskeletons made of this durable and firm compound support and protect the delicate soft tissues of these animals, which lack an internal skeleton.
