| Sumario: | When a negative plant-pathogen interaction is established, the plant activates responses of the innate immune system, thanks to the recognition of virulence factors of the pathogen. Several phytohormones such as auxins, phytoalexins, jasmonic acid and salicylic acid are involved in this response, among others. Recent studies on pathogenic processes in plants, report the involvement of pathogen molecules known as "effectors", capable of altering the structure and cellular function of the host, facilitating their entry and permanence in plants, these effectors are recognized by the plant, activating The plant defense response. A group of effectors known to have the RXLR translocation domain is known, which is highly conserved among various pathogens, mediating entry into host cells. Plants also interact with non-pathogenic microorganisms and little is known about the mechanisms controlling the establishment of these beneficial interactions. The fungi of the genus Trichoderma establish beneficial interactions with plants and are able to promote their growth and development, as well as to activate the plant defense system. It is probable that this interaction is mediated by effector molecules, so the objective of this work was to determine the participation of this type of molecules of Trichoderma virens and Trichoderma atroviride in the promotion of the growth and development of plants of Arabidopsis thaliana and in the Activation of the plant defense system. In this work the expression of 16 Trichoderma spp. In interaction with plants, and the participation of a hydrophobine of T. virens in the activation of plant defense pathways, colonization of tomato roots and in myoparasitic interaction with Rhizoctonia solani was determined. |
