Proteome profiling of enriched membrane-associated proteins unraveled a novel sophorose and cello-oligosaccharide transporter in Trichoderma reesei.

Background: Trichoderma reesei is an organism extensively used in the bioethanol industry, owing to its capability to produce enzymes capable of breaking down holocellulose into simple sugars. The uptake of carbohydrates generated from cellulose breakdown is crucial to induce the signaling cascade that triggers cellulase production. However, the sugar transporters involved in this process in T.

The Cerato-Platanin EPL2 from Is Not Directly Involved in Cellulase Formation but in Cell Wall Remodeling.

is a saprophytic fungus that produces large amounts of cellulases and is widely used for biotechnological applications. Cerato-platanins (CPs) are a family of proteins universally distributed among Dikarya fungi and have been implicated in various functions related to fungal physiology and interaction with the environment. In , three CPs are encoded in the genome: , and .

Use of carbohydrate-directed enzymes for the potential exploitation of sugarcane bagasse to obtain value-added biotechnological products.

Microorganisms, such as fungi and bacteria, are crucial players in the production of enzymatic cocktails for biomass hydrolysis or the bioconversion of plant biomass into products with industrial relevance. The biotechnology industry can exploit lignocellulosic biomass for the production of high-value chemicals. The generation of biotechnological products from lignocellulosic feedstock presents several bottlenecks, including low efficiency of enzymatic hydrolysis, high cost of enzymes, and limitations on microbe metabolic performance.

Small heat shock protein genes are developmentally regulated during stress and non-stress conditions in Blastocladiella emersonii.

Small heat shock proteins (sHsps) are molecular chaperones of low molecular weight involved in an early association with misfolded proteins. In response to heat shock, B. emersonii induces the synthesis of a number of proteins.

Blastocladiella emersonii spliceosome is regulated in response to the splicing inhibition caused by the metals cadmium, cobalt and manganese.

Blastocladiella emersonii is an aquatic fungus of the phylum Blastocladiomycota, localized near the base of the fungal tree. Previous studies have shown that B. emersonii responds to heat shock and cadmium exposure inducing the transcription of a high number of genes.

Trichoderma harzianum transcriptome in response to cadmium exposure.

Cadmium (Cd) is a heavy metal present in the environment mainly as a result of industrial contamination that can cause toxic effects to life. Some microorganisms, as Trichoderma harzianum, a fungus used in biocontrol, are able to survive in polluted environments and act as bioremediators. Aspects about the tolerance to the metal have been widely studied in other fungi although there are a few reports about the response of T.

Hsp genes are differentially expressed during Trichoderma asperellum self-recognition, mycoparasitism and thermal stress.

Heat shock proteins (Hsp) are important factors in the response of organisms to oscillations in environmental conditions. Although Hsp have been studied for a long time, little is known about this protein class in Trichoderma species. Here we studied the expression of Hsp genes during T.

Plant-associated bacteria mitigate drought stress in soybean.

Agriculture accounts for ~ 70% of all water use and the world population is increasing annually; soon more people will need to be fed, while also using less water. The use of plant-associated bacteria (PAB) is an eco-friendly alternative that can increase crop water use efficiency. This work aimed to study the effect of some PAB on increasing soybean tolerance to drought stress, the mechanisms of the drought tolerance process, and the effect of the PAB on promoting plant growth and on the biocontrol of Sclerotinia sclerotiorum.
