Abstract

Trichoderma reesei (Hypocrea jecorina) is a saprophyte fungus involved in the degradation of cell wall polysaccharides from plants. T. reesei has an astonishing ability to produce and secrete cellulases, and is the most important industrial fungus in the production of these enzymes that are used, among other purposes, in the biofuel industry, such as bioethanol. The degradation of the components of lignocellulosic wall is a complex process that requires a series of regulatory proteins to make it more efficient and save unnecessary energy expenditure. This project aims to contribute to the understanding of the molecular mechanisms involved in the process of deconstruction of biomass in T. reesei through the identification of new transcription factors associated with this process. For this, a number of transcription factors potentially involved in the degradation of biomass will be identified by in silico analysis of RNA-seq data and subsequently deleted in order to verify their respective functions. Additionally, DNA binding motifs related to these regulatory proteins will be validated through the analysis of synthetic promoters fused to GFP reporter gene. With the data obtained, will be built a model of gene expression related to the transcription factors identified, enabling a better understanding of the behavior of gene expression of cellulolytic enzymes produced by T. reesei and contributing to the implementation of this fungus in the bioethanol industry.
