“…The auxiliary protein swollenin (Saloheimo et al, 2002;Brotman et al, 2008) was even likely obtained from green plants by LGT (Druzhinina et al, 2018), which is supported by the finding that Trichoderma spp. are frequently found as members of endophytic fungal communities (Gazis and Chaverri, 2010;Yadav et al, 2022) and generally plant symbionts living in their rhizosphere (Harman et al, 2004a). In contrast to numerous genes encoding enzymes, their major regulators XYR1, ACE2 and ACE3 (Benocci et al, 2017) evolved by vertical gene transfer, but not by LGT (Druzhinina et al, 2018).…”

The genus Trichoderma is among the best studied groups of filamentous fungi, largely because of its high relevance in applications from agriculture to enzyme biosynthesis to biofuel production. However, the physiological competences of these fungi, that led to these beneficial applications are intriguing also from a scientific and ecological point of view. This review therefore summarizes recent developments in studies of fungal genomes, updates on previously started genome annotation efforts and novel discoveries as well as efforts towards bioprospecting for enzymes and bioactive compounds such as cellulases, enzymes degrading xenobiotics and metabolites with potential pharmaceutical value. Thereby insights are provided into genomes, mitochondrial genomes and genomes of mycoviruses of Trichoderma strains relevant for enzyme production, biocontrol and mycoremediation. In several cases, production of bioactive compounds could be associated with responsible genes or clusters and bioremediation capabilities could be supported or predicted using genome information. Insights into evolution of the genus Trichoderma revealed large scale horizontal gene transfer, predominantly of CAZyme genes, but also secondary metabolite clusters. Investigation of sexual development showed that Trichoderma species are competent of repeat induced point mutation (RIP) and in some cases, segmental aneuploidy was observed. Some random mutants finally gave away their crucial mutations like T. reesei QM9978 and QM9136 and the fertility defect of QM6a was traced back to its gene defect. The Trichoderma core genome was narrowed down to 7000 genes and gene clustering was investigated in the genomes of multiple species. Finally, recent developments in application of CRISPR/Cas9 in Trichoderma, cloning and expression strategies for the workhorse T. reesei as well as the use genome mining tools for bioprospecting Trichoderma are highlighted. The intriguing new findings on evolution, genomics and physiology highlight emerging trends and illustrate worthwhile perspectives in diverse fields of research with Trichoderma.

“…Plants host microbes in their internal tissues which reside asymptomatically and do not cause any noticeable symptoms of diseases and are called as the endophytic microbes. These endophytic microbiomes provide protection to their host against the stressful environment [1]. Among the endophytic microbes, endophytic fungal communities have been studied the most.…”

“…(especially M. anisopliae) are the most two studied species in terms of commercial production (Zimmermann 2007a(Zimmermann , 2007b. In addition to the use of EPFs in the biological control of insect pests, they have additional roles in nature such as endophytism, plant disease antagonism, plant growth promotion, and rhizosphere colonization (Yadav et al 2022). Therefore, it should be interesting to study the antagonistic activity of these fungi against some plant pathogens to provide their possible potential use in integrated pest management (IPM) strategies for future perspectives.…”

Background Entomopathogenic fungi have long been used as a biopeptide in the biological control of insect pests in agriculture, forestry and veterinary. At the same time, it is known that these fungi have positive effects on plant growth, health, and the antagonist effect against various plant pathogens. Entomopathogenic fungal isolation was performed from soil samples collected from apple orchards and Tropinota (=Epicometis) hirta (Poda) (Coleoptera: Cetoniidae) adults which is an important pest of fruit trees. The isolated fungi were identified at the species level by phylogenetic analysis based on multi-locus sequence approach using various gene sequences (ITS, rpb1, bloc, EF1-α and β-tubulin). The fungi obtained were tested against T. hirta and the apple scab disease, Ventura inaequalis under laboratory conditions. Results Three (Bz isolates) and 15 (AK isolates) entomopathogenic fungi (EPF) were isolated from T. hirta adults and 48 soil samples, respectively. The isolated fungi were identified as Beauveria bassiana (Bz-1, Bz-2, AK-10, AK-14, AK-17, and AK-18), Metarhizium robertsii (Bz-3, AK-4, AK-5, AK-6, AK-7, AK-8, AK-9, AK-11, AK-13, AK-15, and AK-16) and Metarhizium sp. (AK-12). All isolated fungi were tested against T. hirta adults, causing the same mortality but different mycosis values. In addition, the antagonistic effects of fungal isolates against V. inaequalis, the important apple pathogen, were determined and the highest effect was obtained from B. bassiana AK-10 with 69.3%. Conclusion This is the first study to determine the effectiveness of EPF against T. hirta and V. inaequalis, and the results obtained are thought to be useful for the biological control of both pests.
