Chitinases in biological control
Abstract
The public concern over the harmful effects of chemical pesticides on the environment and human health has enhanced the search for safer, environmentally friendly control alternatives. Control of plant pests by the application of biological agents holds great promise as an alternative to the use of chemicals. It is generally recognized that biological control agents are safer and more environmentally sound than is reliance on the use of high volumes of pesticides. Due to the importance of chitinolytic enzymes in insect, nematode, and fungal growth and development, they are receiving attention in regard to their development as biopesticides or chemical defense proteins in transgenic plants and microbial biocontrol agents. In this sense, biological control of some soil-borne fungal diseases has been correlated with chitinase production. Fungi- and bacteria-producing chitinases exhibit antagonism against fungi, and inhibition of fungal growth by plant chitinases has been demonstrated. Insect pathogenic fungi have considerable potential for the biological control of insect pests. Entomopathogenic fungi apparently overcome physical barriers of the host by producing multiple extracellular enzymes including chitinolytic enzymes, which help to penetrate the cuticle and facilitate infection. In this chapter, the role of chitinases in biological control and their potential use in the improvement of biocontrol agents and crop plants by genetic engineering is analyzed in view of recent f…

Chitinases from other sources than yeasts have demonstrated biocontrol activity against plant pathogenic fungi and are widely studied as potential biopesticides, targets for resistance breeding, or as transgenes in genetically modified plants.
“However, chitinases from other sources than yeasts (i.e., filamentous fungi and bacteria) have demonstrated biocontrol activity against plant pathogenic fungi and chitinases are widely studied as potential biopesticides, targets for resistance breeding, or as transgenes in genetically modified plants (Dahiya et al. 2006; Herrera-Estrella and Chet 1999; Nagpure et al. 2014).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
