“…As a result, T. asperellum also promoted benefits in photosynthesis rate (A), stomatal conductance (gs), water use efficiency (WUE), and carboxylation efficiency (Figure 3). Our results are in agreement with the findings of Bae et al (2009) and De Sousa et al (2020) who reported that plants inoculated with Trichoderma spp. reduced the drop on A and gs values, in addition to increasing the photosynthetic area of sugarcane leaves (Figure 6C).…”

“…are widely recognized as phytohormones synthesizers (e.g., auxin) and hormone-like compounds called harzianolide and swollenin, substances that help along with auxin, in the expansion of the cell wall (Rajesh et al, 2016;De Sousa et al, 2020). These compounds enhance not only the shoot dry weight but also the root and rootlet development (De Sousa et al, 2020) involved in water and nutrient absorption, as reported in our study (Supplementary Figure 2). Therefore, sugarcane inoculated with T. asperellum performed better in terms of water and nutrient absorption by the roots compared to the non-inoculated plants, resulting in higher plant height and stalk production (Figure 6).…”

“…These findings are consistent with previous studies that reported that Trichoderma spp. can enhance yield and quality of tomato (Khoshmanzar et al, 2020), wheat (Zhang et al, 2016), rice (Doni et al, 2019;De Sousa et al, 2020), and maize (Fu et al, 2017;Estévez-Geffriaud et al, 2020) under abiotic stresses.…”

“…is a rhizospheric fungus of great agricultural and environmental importance, which can confer numerous beneficial effects in promoting plant growth and development (Harman et al, 2004), in inducing systemic resistance in plants (Kashyap et al, 2017;De Sousa et al, 2020) and as a biocontrol agent for fungal diseases (Harman et al, 2004;Mastouri et al, 2010). There are countless species within the genus Trichoderma, and a highlight has been given to T. asperellum (Harman, 2005;De Sousa et al, 2020;Zhao et al, 2020). Several authors have reported the ability of this group of microorganisms to relieve biotic and abiotic stresses of germinating plants and seeds, reducing the damage caused by ROS (Poveda, 2020).…”

Trichoderma asperellum Inoculation as a Tool for Attenuating Drought Stress in Sugarcane

Drought stress is an important concern worldwide which reduces crop yield and quality. To alleviate this problem, Trichoderma asperellum has been used as a plant growth-promoting fungus capable of inducing plant tolerance to biotic and abiotic stresses. Here, we examined the effect of T. asperellum inoculation on sugarcane plant above and belowground development under drought stress and investigated the role of this fungus on inducing tolerance to drought at physiological and biochemical levels. The experiment was performed in pots under greenhouse conditions, with four treatments and four replicates. The treatments consisted of sugarcane plants inoculated or not with T. asperellum and grown under drought stress and adequate water availability. Drought-stressed sugarcane plants inoculated with T. asperellum changed the crop nutrition and chlorophyll and carotenoid concentrations, resulting in increased photosynthesis rate, stomatal conductance, and water use efficiency compared to the non-inoculated plants. In addition, the antioxidant metabolism also changed, increasing the superoxide dismutase and peroxidase enzyme activities, as well as the proline concentration and sugar portioning. These cascade effects enhanced the root and stalk development, demonstrating that T. asperellum inoculation is an important tool in alleviating the negative effects of drought stress in sugarcane. Future studies should be performed to elucidate if T. asperellum should be reapplied to the sugarcane ratoons.

Members of the fungal genus Trichoderma (Ascomycota, Hypocreales, Hypocreaceae) are ubiquitous and commonly encountered as soil inhabitants, plant symbionts, saprotrophs, and mycoparasites. Certain species have been used to control diverse plant diseases and mitigate negative growth conditions. The versatility of Trichoderma’s interactions mainly relies on their ability to engage in inter- and cross-kingdom interactions. Although Trichoderma is by far the most extensively studied fungal biocontrol agent (BCA), with a few species already having been commercialized as bio-pesticides or bio-fertilizers, their wide application has been hampered by an unpredictable efficacy under field conditions. Deciphering the dialogues within and across Trichoderma ecological interactions by identification of involved effectors and their underlying effect is of great value in order to be able to eventually harness Trichoderma’s full potential for plant growth promotion and protection. In this review, we focus on the nature of Trichoderma interactions with plants and pathogens. Better understanding how Trichoderma interacts with plants, other microorganisms, and the environment is essential for developing and deploying Trichoderma-based strategies that increase crop production and protection.

Co‐inoculation of soybean with plant growth‐promoting microorganisms has the potential to increase yield, and the Amazon is a biome rich in these beneficial microorganisms. Soybean is the most important grain crop in Brazil and is highly benefited by inoculation with Bradyrhizobium spp. strains, both of which represent exotic symbiotic partners. The objective of this study was to evaluate the effects of soybean co‐inoculation with Amazonian strains of Trichoderma asperellum and Bacillus amyloliquefaciens. Greenhouse and field experiments were conducted during the 2020 and 2021 crop seasons in Brazil, respectively. The experimental design was completely randomized in the greenhouse, and randomized blocks were used in the field, both with 3 × 2 factorial schemes. Standard inoculation with Bradyrhizobium and co‐inoculation with T. asperellum and B. amyloliquefaciens was considered the first factor, and the second factor was represented by phosphate fertilization (0 and 100 kg ha−1 of P2O5). The root system volumes were 25% and 17% higher than those of the standard inoculation with T. asperellum and B. amyloliquefaciens, respectively. In 2020, co‐inoculation with T. asperellum increased yield by 15%, plant height by 27%, and net profit by up to 121 USD compared with standard inoculation. In 2021, co‐inoculation with T. asperellum and B. amyloliquefaciens resulted in increases in several growth parameters compared to those with standard inoculation, including 7% and 13% greater yields, and 159 USD and 309 USD increases in net profit, respectively. Our results indicate the possibility of expanding soybean co‐inoculation with local strains of Bacillus and Trichoderma, with benefits for productivity and profitability.
