Abstract
Trichoderma hamatum (Bonord.) Bainier (T. hamatum) belongs to Hypocreaceae family, Trichoderma genus. Trichoderma spp. are prominently known for their biocontrol activities and plant growth promotion. Hence, T. hamatum also possess several beneficial activities, such as antimicrobial activity, antioxidant activity, insecticidal activity, herbicidal activity, and plant growth promotion; in addition, it holds several other beneficial properties, such as resistance to dichlorodiphenyltrichloroethane (DDT) and degradation of DDT by certain enzymes and production of certain polysaccharide-degrading enzymes. Hence, the current review discusses the beneficial properties of T. hamatum and describes the gaps that need to be further considered in future studies, such as T. hamatum's potentiality against human pathogens and, in contrast, its role as an opportunistic human pathogen. Moreover, there is a need for substantial study on its antiviral and antioxidant activities.

[PMID: 37623632 PMCID: PMC10455997 DOI: 10.3390/jof9080861] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 08/08/2023] [Accepted: 08/14/2023] [Indexed: 08/26/2023] Open
Abstract
Clonostachys rosea is an excellent biocontrol fungus against numerous fungal plant pathogens. The cAMP signaling pathway is a crucial signal transduction pathway in fungi. To date, the role of the cAMP signaling pathway in C. rosea mycoparasitism remains unknown. An adenylate cyclase-encoding gene, crac (an important component of the cAMP signaling pathway), was previously screened from C. rosea 67-1, and its expression level was dramatically upregulated during the C. rosea mycoparasitization of the sclerotia of Sclerotinia sclerotiorum. In this study, the function of crac in C. rosea mycoparasitism was explored through gene knockout and complementation. The obtained results show that the deletion of crac influenced the growth rate and colony morphology of C. rosea, as well as the tolerance to NaCl and H2O2 stress. The mycoparasitic effects on the sclerotia of S. sclerotiorum and the biocontrol capacity on soybean Sclerotinia stem rot in ∆crac-6 and ∆crac-13 were both attenuated compared with that of the wild-type strain and complementation transformants. To understand the regulatory mechanism of crac during C. rosea mycoparasitism, transcriptomic analysis was conducted between the wild-type strain and knockout mutant. A number of biocontrol-related genes, including genes encoding cell wall-degrading enzymes and transporters, were significantly differentially expressed during C. rosea mycoparasitism, suggesting that crac may be involved in C. rosea mycoparasitism by regulating the expression of these DEGs. These findings provide insight for further exploring the molecular mechanism of C. rosea mycoparasitism.

Abstract
The fungal P450s catalyze vital monooxygenation reactions in primary and secondary metabolism, which may lead to the production of diverse secondary metabolites. Many of these, such as from the family of trichothecenes, involve in biocontrol activities. The diversified nature of fungal P450 monooxygenases makes their host organisms adoptable to various ecological niches. The available genome data analysis provided an insight into the activity and mechanisms of the fungal P450s. However, still more structural and functional studies are needed to elucidate the details of its catalytic mechanism, and the advance studies are also required to decipher further about their dynamic role in various aspects of trichothecene oxygenations. This mini review will provide updated information on different fungal P450 monooxygenases, their genetic diversity, and their role in catalyzing various biochemical reactions leading to the production of plant growth promoting secondary metabolites.

Abstract
Plants are capable of perceiving microorganisms by coordinating processes to establish different forms of plant–microbe relationships. Plant colonization is governed in fungal and bacterial systems by secreted effector molecules, suppressing plant defense responses and modulating plant physiology to promote either virulence or compatibility. Proteins, secondary metabolites, and small RNAs have been described as effector molecules that use different mechanisms to establish the interaction. Effector molecules have been studied in more detail due to their involvement in harmful interactions, leading to a negative impact on agriculture. Recently, research groups have started to study the effectors in symbiotic interactions. Interestingly, most symbiotic effectors are members of the same families present in phytopathogens. Nevertheless, the quantity and ratio of secreted effectors depends on the microorganism and the host, suggesting a complex mechanism of recognition between the plant and their associated microorganisms. Fungi belonging to Trichoderma genus interact with plants by inducing their defense system and promoting plant growth. Research suggests that some of these effects are associated with effector molecules that Trichoderma delivers during the association with the plant. In this review, we will focus on the main findings concerning the effector molecules reported in Trichoderma spp. and their role during the interaction with plants, mainly in the molecular dialogue that takes place between them.

Abstract
Secondary metabolites are crucial for the establishment of interactions between plants and microbes, as in the case of Trichoderma-plant interactions. In the biosynthetic pathway of secondary metabolites, specific enzymes participate in the formation of hydroxyl and epoxy groups, belonging to the p450 monooxygenases family. Here, we show that the product of the gene TvCyt2 from Trichoderma virens encodes a new protein homologous to the cytochrome p450, which is down-regulated at the beginning of Trichoderma-Arabidopsis interaction. To investigate its role in the interactions established by Trichoderma spp., we analyzed the metabolic profile obtained from the overexpressing (OETvCyt2) and null mutant (Δtvcyt2) strains, observing that the OETvCyt2 strains produce a higher concentration of some metabolites than the wild-type (WT) strain. Δtvcyt2 strains showed a decreased antagonistic activity against Rhizoctonia solani in antibiosis assays. Arabidopsis plants cocultivated with the OETvCyt2 strains showed stronger induction of systemic acquired resistance than plants cocultivated with the WT strain, as well as increases in biomass and fitness. Our data suggest that the product of the TvCyt2 gene is involved in secondary metabolite biosynthesis, which can increase antagonistic activity with phytopathogenic fungi and the capacity to promote plant growth.

Abstract
The plant health- and growth-promoting biological inoculant (bio-inoculant) Trichoderma hamatum LU592 was transformed with the constitutively expressed green fluorescent protein (gfp) and hygromycin B resistance (hph) genes to specifically monitor the isolate in the root system of Pinus radiata within a strong indigenous Trichoderma population. A modified dilution plating technique was developed to allow the determination of the mycelia proportion of total propagule levels. LU592 was shown to colonize the rhizosphere most effectively when 10(5) spores per pot were applied compared with inoculum concentrations of 10(3) and 10(7) spores per pot. LU592 extended its zone of activity beyond the rhizosphere to at least 1 cm away from the root surface. A positive relationship was shown between P. radiata root maturation and the spatial and temporal proliferation of LU592 in the root system. A steep increase in mycelia levels and proportion of penetrated root segments was observed after 12 weeks. This study reinforces the value of genetic markers for use in ecological studies of filamentous fungi. However, despite isolate-specific recovery of the introduced isolate, it was shown that total propagule counts do not always correlate with the amount of viable mycelium present in the root system. Therefore, it is proposed that the differentiation of mycelia from spores and root penetration is used as more accurate measures of fungal activity.
