“…DS8, 10, and 16 significantly improved the activities of SOD, PAL, CAT, and POD, and Pro contents; while reducing MDA contents under pot cultures. This was consistent with the results in Codonopsis pilosula after inoculation with Trichoderma strain RHTA01, ultimately alleviating the damage caused by abiotic stress ( Wang et al, 2021 ). In addition, endophytic fungi can induce systemic resistance (SR) in host plants by triggering the transmission of signaling molecules such as jasmonic acid (JA) and ethylene (ET) ( De Lamo & Takken, 2020 ).…”

“…They can enhance the biomass of cocoa trees by promoting the uptake and distribution of N ( Christian, Herre & Clay, 2019 ). Inoculating Codonopsis pilosula with Trichoderma led to an increased SS activity ( Wang et al, 2021 ) and Achnatherum inebrians with Epichloë gansuensis that of increased the GS and NiR ( Wang et al, 2018 ), ultimately benefiting biomass. In this study, DS10 and 13 enhanced intercellular CO 2 concentration; net photosynthetic rate; activities of SS, SPS, NR, and GS; and improved the efficiency of C and N assimilation, consequently promoting S. miltiorrhiza growth.…”

Background Endophytic fungi can enhance the growth and synthesis of secondary metabolites in medicinal plants. Salvia miltiorrhiza Bunge is frequently employed for treating cardiovascular and cerebrovascular ailments, with the primary bioactive components being salvianolic acid and tanshinone. However, their levels in cultivated S. miltiorrhiza are inferior to that of the wild herbs, so the production of high-quality medicinal herbs is sharply declining. Consequently, the utilization of beneficial endophytic fungi to improve the yield and quality of S. miltiorrhiza holds great significance for the cultivation of medicinal plants. Methods In this study, nine non-pathogenic, endophytic fungal strains were introduced into sterile S. miltiorrhiza seedlings and cultivated both in vitro and in situ (the greenhouse). The effects of these strains on the growth indices, C and N metabolism, antioxidant activity, photosynthesis, and content of bioactive ingredients in S. miltiorrhiza were then evaluated. Results The results showed that the different genera, species, or strains of endophytic fungi regulated the growth and metabolism of S. miltiorrhiza in unique ways. These endophytic fungi primarily exerted their growth-promoting effects by increasing the net photosynthetic rate, intercellular CO2 concentration, and the activities of sucrose synthase, sucrose phosphate synthase, nitrate reductase, and glutamine synthetase. They also enhanced the adaptability and resistance to environmental stresses by improving the synthesis of osmoregulatory compounds and the activity of antioxidant enzymes. However, their regulatory effects on the growth and development of S. miltiorrhiza were affected by environmental changes. Moreover, the strains that significantly promoted the synthesis and accumulation of phenolic acids inhibited the accumulation of tanshinones components, and vice versa. The endophytic fungal strains Penicillium meloforme DS8, Berkeleyomyces basicola DS10, and Acremonium sclerotigenum DS12 enhanced the bioaccumulation of tanshinones. Fusarium solani DS16 elevated the rosmarinic acid content and yields in S. miltiorrhiza. The strain Penicillium javanicum DS5 improved the contents of dihydrotanshinone, salvianolic acid B, and rosmarinic acid. The strains P. meloforme DS8 and B. basicola DS10 improved resistance. Conclusion Various endophytic fungi affected the quality and yield of S. miltiorrhiza by regulating different physiological and metabolic pathways. This study also provides a novel and effective method to maximize the effects of beneficial endophytic fungi by selecting specific strains to design microbial communities based on the different ecological functions of endophytic fungi under varying environments and for specific production goals.

“…This immune response involves the coordination of multiple signal molecules, forming complex regulatory networks responsible for mediating the synthesis of secondary metabolites [62][63][64]. Infection by endophytic fungi activates cell surface receptors, influencing the behaviour of signalling molecules such as SA, H 2 O 2 , and NO [9]. Through symbiotic relationships with microbes, plants can enhance their defence responses and manipulate the expression of defence genes, a process known as induced systemic resistance (ISR) [65].…”

Paraphoma chrysanthemicola, an endophytic fungus isolated from the roots of Codonopsis pilosula, influences salicylic acid (SA) levels. The interaction mechanism between SA and P. chrysanthemicola within C. pilosula remains elusive. To elucidate this, an experiment was conducted with four treatments: sterile water (CK), P. chrysanthemicola (FG), SA, and a combination of P. chrysanthemicola with salicylic acid (FG+SA). Results indicated that P. chrysanthemicola enhanced plant growth and counteracted the growth inhibition caused by exogenous SA. Physiological analysis showed that P. chrysanthemicola reduced carbohydrate content and enzymatic activity in C. pilosula without affecting total chlorophyll concentration and attenuated the increase in these parameters induced by exogenous SA. Secondary metabolite profiling showed a decrease in soluble proteins and lobetyolin levels in the FG group, whereas SA treatment led to an increase. Both P. chrysanthemicola and SA treatments decreased antioxidase-like activity. Notably, the FG group exhibited higher nitric oxide (NO) levels, and the SA group exhibited higher hydrogen peroxide (H2O2) levels in the stems. This study elucidated the intricate context of the symbiotic dynamics between the plant species P. chrysanthemicola and C. pilosula, where an antagonistic interaction involving salicylic acid was prominently observed. This antagonism was observed in the equilibrium between carbohydrate metabolism and secondary metabolism. This equilibrium had the potential to engage reactive oxygen species (ROS) and nitric oxide (NO).

“…The rhizocompetent nature of Trichoderma species allows it to colonize roots, triggering the plant immune system (induced systemic resistance; ISR), and preactivation (priming) of the molecular mechanisms of defense against several potent phytopathogens and the stress challenged conditions [64][65][66][67]. Furthermore, colonization of this beneficial fungi promotes plant growth and also upgrades the host plants against various abiotic and biotic stresses [7,68]. It balances different phytohormone-dependent pathways among which salicylic acid (SA), jasmonates (JA), ethylene (ET), abscisic acid (ABA), auxin (indole-3-acetic acid: IAA), and gibberellins (GA) are the most relevant-and modulating the levels of growth and defense regulatory proteins [2,11,54,[69][70][71].…”

Trichoderma - Technology and Uses

Trichoderma has been studied widely. It has been found to play a major role in agricultural production. Around the world scientists and farmers have taken advantage of this knowledge. It is reported to improve plant growth of many crops such as tomato, lettuce, maize, beans, cabbage sugarcane and many more crops. There are two broad categories where Trichoderma plays a major role which is its use as a biofertilizer as well as a biofungicide. Its use as a biofertilizer has been aggravated by its ability to produce volatile compounds, ability to solubilize phosphates making them available to the plant. Moreover, farmers use it as a biofertilizer because it improves the uptake of macro and micro nutrients by the plant. As a biofungicide, Trichoderma is not to control many pathogens from various crops. This includes the control of pathogens such as Rhizoctonia, Phytophthora, Rhizoctonia, Sclerotinia, Phythium, Fusarium, Sclerotinia species and Galumannomyces. The mechanisms used by Trichoderma as a biofungicide includes, antibiosis, mycoparasitism, competitive advantage in the rhizosphere as well as priming of the crop self-defense mechanisms. The purpose of this book chapter is to highlight the importance of Trichoderma in agriculture as a biofertilizer and biofungicide.
