“…Plant growth-promoting rhizobacteria (PGPR) can adapt to plants stressed by pathogen attacks. Mycorrhizae and PGPR can control vary of pathogens directly through competition and antibiosis and indirectly through chemical and physiological responses by changing enzyme activity and increasing chemical compounds, which can inhibit the development of pathogens [7,10,31]. Mycorrhiza protects plant roots by infecting the plant root cortex and helping plants absorb nutrients needed by plants, thus increasing plant resistance to pathogen attack by releasing compounds that can prevent infection by pathogens such as phenols and phytoalexins [10,32,33].…”

“…The two types of PGPF commonly used are mycorrhiza and Trichoderma sp. Arbuscular mycorrhiza is an obligate fungus antagonistic to plant pathogens [10,11]. The symbiosis between plant roots and soil fungi has many benefits in agriculture, including increasing water absorption, nutrient status of plants, and plant resistance to diseases and other unfavourable conditions [12].…”

Fusarium oxysporum f.sp lycopersici is a fungus that causes wilt disease in tomatoes, attacking nurseries to mature plants. This study aims to examine several plant growth-promoting microorganisms (PGPM) to control Fusarium wilt and increase tomato production. The study was designed with a completely randomized design in a screen house with four treatments and three experimental units. The treatments tested were mycorrhiza 5 g per plant (M), a mixed solution containing Bacillus sp., Pseudomonas sp., and Trichoderma sp. 10 ml per plant (PGPM1), and combination treatment M and PGPM1 (PGPM2). The study showed a more extended incubation period of the pathogen-causing diseased plants with the treatment of PGPM2 compared to other treatments. The lower intensity of wilt disease was also found in the PGPM2 treatment. Consistently the same treatment also had a better effect on the number of leaves, plant height, and fresh tomato fruit production than other treatments. This study showed a significant effect of PGPM in controlling Fusarium wilt and increasing tomato production.

“…They are involved in several complicated networks, through which they moderate responses to different stimuli. The hormones which primarily regulate plant defence against pathogens are jasmonic acid (JA), ethylene (ET), salicylic acid (SA), and abscisic acid (ABA) (Prasad et al 2017). In case of biotrophic pathogen, effective defence against biotrophic pathogens is mainly due to PCD and activation of defence related to salicylic aciddependent defence pathways which trigger SAR.…”

Plants have improved robust mechanisms to recognize and respond to various environmental stimuli such as stress like biotic and abiotic stress. Biotic stress includes fungal, bacterial, and viral pathogens invasion, progression, and development of diseases. The plants have to encounter these microorganisms during 24-h a day. So as to protect themselves, plants have evolved numerous passive and active defence mechanisms to disrupt the progression of pathogens. The plant circadian clock stimulates daily rhythm in the activity of countless processes. These rhythms are harmonized to the diurnal day/night cycle by light as well as temperature. They control defence responses in plants against biotrophic and necrotrophic pathogens by modulating the expression of various genes of defence component pathways such as opening and closing of stomata (CIRCADIAN CLOCK ASSOCIATED 1 (CCA1) and LATE ELONGATED HYPOCOTYL (LHY)), ROS and RNS, Myb factor, E3 ubiquitin protein ligase and ubiquitin-like protein, arachidonic acid, Isochorismate Synthase1 (ICS1), EDS1, COI, JAZ genes, etc. Additionally, redox state of a cell regulates defence components and circadian rhythm. Altogether these studies have revealed that circadian clock helps in regulating the pathways of defence essential for the plant survival.

“…The interaction behaviour of fungi with host is largely determined by its genetic makeup, e.g. genome of pathogenic fungi contains virulence effector genes that are responsible for pathogenicity of the fungi (Prasad et al 2017). Interestingly some of these virulence genes are present across different classes of fungus (Schafer 1994).…”

Among the varieties of pathogens infecting plants, fungal pathogens are infamous for causing extensive damage to the plants. The establishment of fungal pathogen on plant tissues is largely determined by the cross-reactivity of the pathogen-secreted biomolecules with host immune response. Plants alleviate the stressful environment by employing different stress-adaptive responses. Particularly, to fend off pathogen and to keep them healthy, plants have evolved a highly complex defence response. The robustness of the plant immunity against invading fungus depends on how the components of the shared signalling network are manoeuvred by the plant for its own defence. However, due to the rapid rate of evolution of fungus pathogenesis genes coupled with global climate changes, the conditions are becoming more favourable for growth and progression of the fungal pathogens. Consequently, the incidences of fungus attack on otherwise resistant host species have now escalated. Thus, the important challenge facing global agriculture is to minimise the crop losses incurred due to plant diseases. In this context, a deeper insight into the mechanism of plant-fungi interaction is necessary to combat the invading pathogens. In this chapter, we have touched upon the mechanistic aspect of plant-fungi interaction and how this information can be utilised strategically for designing climate smart crops.
