What is role of chitinase against fungus defence in plants?5 answersChitinases play a crucial role in plant defense against fungal pathogens by breaking down chitin, a major component of fungal cell walls. These enzymes are produced by various organisms, including plants, bacteria, and insects. In the context of plant-fungus interactions, some fungi have evolved effector proteins with chitinase activity to suppress chitin-triggered immunity in plants. For example, the cucurbit powdery mildew fungus expresses effector proteins that act as chitinases to prevent the activation of chitin-triggered immunity, aiding in fungal survival and development in plant environments. Additionally, the expression of chitinase genes in plants, like CaChiIII7 in pepper, is crucial for defense against fungal pathogens like Colletotrichum acutatum, as these enzymes help activate plant immunity responses and inhibit pathogen proliferation.
What is the overview of chitinases?5 answersChitinases are enzymes that break down chitin, a polymer found in insect cuticles, fungal cell walls, and crustacean shells. They play crucial roles in various fields like medicine, agriculture, and environmental management. Chitinases have diverse applications, including biocontrol against pathogenic fungi and insects, synthesis of chitooligosaccharides, waste management, and even as biocontrol agents against disease-causing larvae. In the medical field, chitinases like CHIT1 and YKL-40 are studied as potential biomarkers for inflammatory diseases, aiding in disease monitoring and predicting prognosis. Furthermore, chitin and chitinases are being investigated for their roles in allergic asthma, where chitin induces immune responses leading to airway inflammation, and chitinase inhibitors show promise in treating inflammatory lung diseases.
What is the effect of chitinase on the growth of cancer cells?4 answersChitinase has been found to inhibit the growth of cancer cells. In vitro studies have shown that chitinase from Trichosanthes dioica seeds inhibited the growth of Ehrlich ascites carcinoma, HCT-116, and MCF-7 cells in a dose-dependent manner. In vivo studies on mice bearing EAC cells also demonstrated significant inhibition of EAC cell growth after treatment with chitinase. The anticancer activity of chitinase is attributed to the induction of apoptosis in cancer cells. Chitinase from Talaromyces funiculosus strain CBS 129594 also exhibited anticancer activity, inhibiting the growth of MCF7, HCT116, and HepG2 cancer cell lines. Additionally, chitinase has been shown to inhibit cancer cell migration by activating Akt signaling. These findings suggest that chitinase has potential as an anticancer agent, with the ability to inhibit cancer cell growth and migration.
How can chitinase be used to control plant fungi?5 answersChitinase can be used to control plant fungi by improving plant resistance to fungal diseases and reducing the severity of symptoms. Chitinase PbChia1, identified in, is a secreted chitinase that can bind to chitin and decrease the resting spores of Plasmodiophora brassicae, the causal agent of clubroot disease. Overexpression of PbChia1 in Arabidopsis thaliana increased resistance to P. brassicae and other pathogens, such as Pst DC3000, Sclerotinia sclerotiorum, and Rhizoctonia solani. This indicates that PbChia1 is a candidate gene for broad-spectrum disease resistance in breeding. Additionally, chitinase from Drosera capensis, as described in, shows high activity against chitin and fungicidal properties against Parastagonospora nodorum, highlighting its potential as a biofungicide. Furthermore, the chitin-binding effector CHBE, identified in, is involved in manipulating chitin-triggered immunity in powdery mildew fungi. Chitinase-producing microorganisms, such as the cold-adapted strain Pseudomonas GWSMS-1 from Antarctica described in, can also be used for biological control of plant fungi, especially at low temperatures.
Have extracted chitinase been used as bioinsecticide in agriculture?3 answersChitinases have been evaluated as biopesticides in agriculture, both alone and in combination with other bioactive compounds. However, there is a lack of interest from agriculturalists in utilizing chitinases as a biopesticide.
Is chitinase used as bioinsectiside in industry?5 answersChitinase is used as a bioinsecticide in the industry. It has gained attention as a potential alternative to chemical fungicides due to the increasing occurrence of resistance to conventional insecticides. Chitinases are enzymes that break down chitin, a polymer found in the cell walls of fungi, shells of crustaceans, and cuticles of insects. The resistance of chitin to degradation has led to increased interest in chitin-hydrolyzing enzymes like chitinases. The use of chitinases in everyday practice is promoted to meet industry demands for green, energy-efficient, pollution-free, and economically profitable chitin use. Chitinases have also been studied for their potential in the control of fungal pathogens and insect pests. The inducible nature of chitinases and their low activity can be solved by biotechnology to enhance their efficiency for practical applications.
