“…Trichoderma species play an important role in suppression of plant disease by directly antagonizing with root and foliar pathogens as well as by inducing resistance in plants. The Trichoderma ‐induced resistance in plants leads to physiological and biochemical changes including enhanced defence enzymatic activity, upregulation of defence‐related genes, and changes in metabolic profiles (Mastouri et al ., 2010; Contreras‐Cornejo et al ., 2011; Carreras‐Villasenor et al ., 2012). A recent study showed that Trichoderma harzianum T22 can enhance the production of volatile organic compounds (VOCs) in tomato leading to an increased attractiveness towards aphid parasitoids (Coppola et al ., 2017).…”

SummaryPlants can re‐programme their transcriptome, proteome and metabolome to deal with environmental and biotic stress. It has been shown that the rhizosphere microbiome has influence on the plant metabolome and on herbivore behaviour. In the present study, Trichoderma gamsii was isolated from Arabidopsis thaliana rhizosphere soil. The inoculation of roots of Arabidopsis thaliana with T. gamsii significantly inhibited the feeding behaviour of Trichoplusia ni and affected the metabolome as well as the content of phytohormones in Arabidopsis leaves. T. gamsii‐treated plant leaves had higher levels of amino acids and lower concentrations of sugars. In addition, T. gamsii‐treated plant leaves had more abscisic acid (ABA) and lower levels of salicylic acid (SA) and indole‐3‐acetic acid (IAA) in comparison with the untreated plants. Furthermore, the inoculation with T. gamsii on different signalling mutants showed that the induction of defences were SA‐dependent. These findings indicate that T. gamsii has potential as a new type of biocontrol agent to promote plant repellence to insect attacks.

“…From spore germination to nutrient sensing to detection of pheromones for initiation of a mating response or activation of chemical warfare to fight competitors, fungi send signals and react to signals (13,606,607). These extracellular signals are received by uptake of low-molecular-weight substances and intracellular activation of a signaling pathway or by binding of a ligand to a membrane receptor which is responsible for signal transmission.…”

“…Besides being extensively used as biological control agents and biofactories (6), several members of the genus Trichoderma have emerged as fungal models for understanding (i) asexual reproduction (7,(12)(13)(14), (ii) light and oxidative stress signaling (12,15), (iii) mechanisms of vesicle transport and secretory pathways (16,17), and (iv) synthesis of lytic enzymes and antifungal secondary metabolites (16,(18)(19)(20). Furthermore, Trichoderma spp.…”

SUMMARYThe genusTrichodermacontains fungi with high relevance for humans, with applications in enzyme production for plant cell wall degradation and use in biocontrol. Here, we provide a broad, comprehensive overview of the genomic content of these species for “hot topic” research aspects, including CAZymes, transport, transcription factors, and development, along with a detailed analysis and annotation of less-studied topics, such as signal transduction, genome integrity, chromatin, photobiology, or lipid, sulfur, and nitrogen metabolism inT. reesei,T. atroviride, andT. virens, and we open up new perspectives to those topics discussed previously. In total, we covered more than 2,000 of the predicted 9,000 to 11,000 genes of eachTrichodermaspecies discussed, which is >20% of the respective gene content. Additionally, we considered available transcriptome data for the annotated genes. Highlights of our analyses include overall carbohydrate cleavage preferences due to the different genomic contents and regulation of the respective genes. We found light regulation of many sulfur metabolic genes. Additionally, a new Golgi 1,2-mannosidase likely involved inN-linked glycosylation was detected, as were indications for the ability ofTrichodermaspp. to generate hybrid galactose-containingN-linked glycans. The genomic inventory of effector proteins revealed numerous compounds unique toTrichoderma, and these warrant further investigation. We found interesting expansions in theTrichodermagenus in several signaling pathways, such as G-protein-coupled receptors, RAS GTPases, and casein kinases. A particularly interesting feature absolutely unique toT. atrovirideis the duplication of the alternative sulfur amino acid synthesis pathway.

“…The transcriptional regulators encoded by brlA, stuA, medA, abaA, and wetA program sequential development from conidiophore differentiation to spore maturation (38). Mining of the Trichoderma genomes in a search for orthologs of these genes showed that almost all genes are present (14). Interestingly, there is no ortholog of brlA, which determines the conidiophore vesicle, a structure apparently not formed in Trichoderma conidiophores (22).…”

“…These effects of light may also be reflected in the ecological behavior of Trichoderma given that carbon sources at the soil surface are different from those associated with roots and buried organic matter. Low pH seems to be a determinant for conidiation, with differences from species to species or even isolate to isolate (14,129). Choice of biocontrol strains for soils with different pH should take into account, among other factors, how pH modulates growth and conidiation.…”

Trichoderma species are widely used in agriculture and industry as biopesticides and sources of enzymes, respectively. These fungi reproduce asexually by production of conidia and chlamydospores and in wild habitats by ascospores. Trichoderma species are efficient mycoparasites and prolific producers of secondary metabolites, some of which have clinical importance. However, the ecological or biological significance of this metabolite diversity is sorely lagging behind the chemical significance. Many strains produce elicitors and induce resistance in plants through colonization of roots. Seven species have now been sequenced. Comparison of a primarily saprophytic species with two mycoparasitic species has provided striking contrasts and has established that mycoparasitism is an ancestral trait of this genus. Among the interesting outcomes of genome comparison is the discovery of a vast repertoire of secondary metabolism pathways and of numerous small cysteine-rich secreted proteins. Genomics has also facilitated investigation of sexual crossing in Trichoderma reesei, suggesting the possibility of strain improvement through hybridization.
