Chitinases in plants
WebSep 1, 2024 · Chitinases are present in diverse form of organisms from bacteria, fungi, insects, plants. Plant chitinases are part of pathogenesis-related proteins. When plant (host) cells are under pathogen stress, plant chitinases are strongly expressed and hence plant chitinases play a critical part against fungal pathogens. WebChitinases can be exploited for their use in control of fungal and insect pathogens of plants [21,22]. Chitinase activity also acts as an indicator showing the activity of fungi in soil …

WebSep 18, 2014 · Chitinases from the GH19 family are found mainly in plants , but they have also been described in bacteria, viruses and nematodes –. All fungal chitinases described thus far belong to the GH18 family, and this family is derived from an ancient gene family widely expressed in Archaea, Bacteria and Eukarya [15] .
WebJul 28, 2015 · The plant chitinases are generally endochitinases and smaller in molecular weight as compared to the insect chitinases. Many plants continuously express chitinases in tuber, stem, and root. WebIndeed, the first plant chitinase for which a three-dimensional structure was solved had been isolated from barley seeds. Moreover, the finding that a chitinase could rescue a somatic embryo mutant was the first evidence of a non-defensive function.
WebApr 3, 2012 · In flowering plants, class I chitinases are important pathogenesis-related proteins, functioning in the determent of herbivory and pathogen attack by acting on insect exoskeletons and fungal cell walls. Within the carnivorous plants, two subclasses of class I chitinases have been identified to play a role in the digestion of prey.
