Abstract：

Source：Chen J., Vallikkannu M., Karuppiah V. (2020) Systemically Induced Resistance Against Maize Diseases by Trichoderma spp.. In: Sharma A., Sharma P. (eds) Trichoderma. Rhizosphere Biology. Springer, Singapore.Maize (Zea mays) is a vital crop for human food, animal feed, and biofuel generation. But production is altogether diminished because of several pathogens. Trichoderma species incorporates numerous imperative in farming and is used as biological control agents (BCAs). A group of elicitors produced by the Trichoderma hyphae are able to induce distinctive sorts of defensive signals inside the plants through activation of salicylic acid (SA), jasmonic acid (JA), brassinolide (BR), reactive oxygen species (ROS), and defense enzymes. Hyd1 and cellulase are the elicitors obtained from Trichoderma harzianum that were found to recognize root target proteins. Activation of these genes induces the plant to produce compounds associated with the reduction of pathogens invasion and improve the biochemical activities for the plant growth and development. The basic target of this chapter is to display the efficacy of Trichoderma on the systemically induced resistance against maize diseases.
