“…The potential of Trichoderma to alleviate biotic stress has been shown in several studies (Khana et al, 2020;Ferreira and Musumeci, 2021). Their antifungal activity relies on several mechanisms: mycoparasitism (suppression, parasitization, or killing of other fungi) (Druzhinina et al, 2011), antibiosis (production of toxins that are detrimental to other fungi), and competition (Khana et al, 2020). Trichoderma can induce resistance in plants (Hoitink et al, 2006;Nawrocka and Małolepsza, 2013) and enhance tolerance against abiotic stresses such as drought and extreme temperatures, salinity, and heavy metal accumulation (Khana et al, 2020).…”

In addition, Trichoderma can act as plant growth promoters by, for example, improving nutrient availability and nitrogen use efficiency in plants (Carrero-Carroń et al, 2016;Khana et al, 2020;Meher et al, 2020).…”

The vascular disease Verticillium wilt of cacao (Theobroma cacao), caused by the soilborne fungus Verticillium dahliae, is often qualified as a “minor” disease. However, it can cause severe losses locally, for example, in western Uganda and northeast of the Democratic Republic of Congo. This disease is difficult to control, notably due to an extended host range and prolonged survival in the soil. Therefore, Verticillium wilt must be addressed through an integrated disease management strategy as employed for other tree crops such as olive. Few studies, nonetheless, have focused on how to confront this disease in cacao. This paper aims to provide an overview of our knowledge on Verticillium wilt on cacao and the integrated disease management strategies for preventing and controlling it. Promising avenues based on findings in other crops that could be adapted to cacao are also explored. Good agricultural practices, genetic resistance, biological control, induced resistance, and the use of organic amendments with or without biocontrol agents are discussed. Moreover, the potential benefits of some of these solutions toward the resistance to other cacao diseases, abiotic stress, and nutrition improvement are presented.

“…Besides the arbuscular mycorrhizal fungi, other fungal root endophytes, such as some strains in the genus Trichoderma , have parallel mutualistic roles compared to mycorrhizal fungi, enhancing plant growth and resistance to abiotic and biotic stresses ( Harman and Uphoff, 2019 ). One main difference compared to AMF is that Trichoderma is relatively easy to culture, which can explain the successful earlier application of Trichoderma in agriculture ( Field et al, 2021 ; Khan et al, 2021 ). Plant beneficial fungal strains of Trichoderma (hereafter Trichoderma ) have been considered a free-living opportunistic avirulent plant symbiont ( Harman et al, 2004 ).…”

The Role of Plant-Associated Bacteria, Fungi, and Viruses in Drought Stress Mitigation

et al. 2021

Drought stress is an alarming constraint to plant growth, development, and productivity worldwide. However, plant-associated bacteria, fungi, and viruses can enhance stress resistance and cope with the negative impacts of drought through the induction of various mechanisms, which involve plant biochemical and physiological changes. These mechanisms include osmotic adjustment, antioxidant enzyme enhancement, modification in phytohormonal levels, biofilm production, increased water and nutrient uptake as well as increased gas exchange and water use efficiency. Production of microbial volatile organic compounds (mVOCs) and induction of stress-responsive genes by microbes also play a crucial role in the acquisition of drought tolerance. This review offers a unique exploration of the role of plant-associated microorganisms—plant growth promoting rhizobacteria and mycorrhizae, viruses, and their interactions—in the plant microbiome (or phytobiome) as a whole and their modes of action that mitigate plant drought stress.
