We present a case study report into nutritional competition between Trichoderma spp. isolated from wild raspberries and fungal phytopathogenic isolates (Colletotrichum sp., Botrytis sp., Verticillium sp. and Phytophthora sp.), which infect soft fruit ecological plantations. The competition was evaluated on the basis of nutritional potentiates. Namely, these were consumption and growth, calculated on the basis of substrate utilization located on Biolog® Filamentous Fungi (FF) plates. The niche size, total niche overlap and Trichoderma spp. competitiveness indices along with the occurrence of a stressful metabolic situation towards substrates highlighted the unfolding step-by-step approach. Therefore, the Trichoderma spp. and pathogen niche characteristics were provided. As a result, the substrates in the presence of which Trichoderma spp. nutritionally outcompete pathogens were denoted. These were adonitol, D-arabitol, i-erythritol, glycerol, D-mannitol and D-sorbitol. These substrates may serve as additives in biopreparations of Trichoderma spp. dedicated to plantations contaminated by phytopathogens of the genera Colletotrichum sp., Botrytis sp., Verticillium sp. and Phytophthora sp.

“…A diverse group of metabolites produced by the endophytes can impart the host plant to overcome the stress (Khan et al 2017 ). Immunized through ISR plays a vital role in the protection from pathogenic invasions, exhibition of varied resistance methods, efficient utilization of energy, and exploitation of genetic ability to induce resistance in the plants which are vulnerable for diseases (Latha et al 2019 ). Plants are also protected from the parasitic nematodes due to ISR.…”

“…Plants are also protected from the parasitic nematodes due to ISR. Bacterial endophytes like B. amyloliquefaciens , Bacillus pumilus , Bacillus subtilis , P. fluorescens , P. syringae, and S. marcescens can induce ISR (Latha et al 2019 ). The following section gives an elaborate account of the endophyte-associated ISR in plants.…”

“…Endophytic bacterial strains of B. cepacia and Ralstonia solanacearum were reported to suppress the activity of fusaric acid, a toxin secreted by Fusarium species, a major wilt-causing pathogen (Toyoda and Utsumi 1991 ). The autoinducer-mediated quorum-sensing of endophytes can impair the virulence of pathogens to inflict diseases, which is of paramount importance (Latha et al 2019 ).…”

Endophytes reside within internal tissues of living plants without causing any harm to the host. The influence of these microbial communities on plant growth, yield, stress, and disease resistance, has been identified as potential research priorities in agriculture. In this chapter, we aim to explore the diverse host–endophyte interactions for plant growth promotion and health. Initially, the colonization of endophytes in specific plant tissues is discussed along with their mechanism of entry, habitat selection, response to stimuli, and evasion of the plant immunity. Endophytic microbes promote plant growth through different types of direct and indirect mechanisms. Plant growth-promoting endophytes (PGPE) play a vital role in phytohormone production, nutrient acquisition, nitrogen fixation, and solubilization of minerals. Further, indirect mechanisms (like suppression of plant pathogens by producing volatile organic compounds, antagonizing agents, and quorum quenchers) are also discussed in detail. Siderophores production and the secretion of different hydrolytic enzymes like chitinases, glucanases, and proteases also help in the induction of systemic resistance and protection of the host plants. Bioactive metabolites derived from endophytes serve as excellent therapeutic agents and have potential applications in agriculture, cosmetics, pharmaceutical, and food industries. Hereby, this chapter highlights the scientific rationale behind using endophytic microbiomes as potential biofertilizers, biopesticides, and biocontrol agents.

“…Endophytic bacteria are considered a subclass of rhizospheric bacteria that have acquired the ability to invade and colonize different parts of plant tissues [2]. They play an imperative role to maintain the health of their host, as they can confer tolerance/resistance to the host plants from abiotic and biotic stresses and help in enhancing growth and yields [6][7][8][9][10]. Plant-Endophyte associations were the subject of study for many years.…”

Bacterial endophytes interact closely with plant tissues and constitute an essential part of the plant microbiome. These interactions can promote plant growth and elicit specific defense responses against abiotic stresses and pathogen attacks. In this paper, we review the role of endophytic bacteria in modulating defenses of the host rendering the entire plant more resistant to pathogens and pests. The endophyte-induced resistance will probably introduce a new factor when consid-ering plant-pathogen interactions. The impact of the bacterial endosymbionts on the host leading to the priming state is also discussed since it confers a specific adaptation of the plant to the biotic threat.
