... This association yields benefits to both the plant and the fungi. The VAM associations exist in coconut roots with varying diversity in different coconut cropping systems (Ramesh, 1982;, coconut cultivars (Thomas and Ghai, 1987), and coconut growing soils (Jayasundara, 1988). Number of fungal species of ten genera has been tabulated in Table 1 that have been identified from coconut grown soils in India and Sri Lanka (Ramesh, 1982;Jayasundara, 1988;Rajeshkumar et al., 2015). ...

... Despite the fact that PEs and essential oils (EOs) contain a wide range of BAMs with positive effects on human health, their application in the FBs production is still insufficent. Recently, many researches have been conducted on a numerous plant species and their potential use in almost all categories of FBs production (energy drinks, sport drinks, enriched fruit juice and dairy products, nutraceutical drinks etc.) (Dini, 2019;Ghoshal, 2019), as well as the development of many plant-based formulas for medicinal purposes (Alalwan et al., 2017;Bultosa et al., 2020). The production of PEs using improved conventional and advanced extraction techniques, as well as determining their functionality (bioavailability, in vivo and in vitro studies, genotoxicity, cytotoxicity, safety in general), contributed to the improvement in the development and fortification of the FBs (Eksi et al., 2019;Garcia-Llatas et al., 2015). ...

... The host range of Fo varies from vegetables (bottle gourd and tomato), flowers (tulips and carnations), field crops (cotton and chickpea) to plantation crops (banana, dates, and palms) (Pietro et al., 2003;Rana et al., 2017;Edel-Hermann and Lecomte, 2019). Despite showing a broad host range, strains of Fo are highly host specific and are genetically and morphologically distinct (Mandeel et al., 2005;Leslie and Summerell, 2008;Palmero et al., 2009;Edel-Hermann and Lecomte, 2019). Together, these hostspecific forms constitute a consortium referred to as F. oxysporum species complex (FOSC) (Edel-Hermann and Lecomte, 2019). ...
... is a cosmopolitan soil inhabitant that has been recovered from many parts of the world ( Leslie & Summerell 2006). F. equiseti is especially common in drier areas such as Bahrain ( Mandeel 1996), although it also can be recovered from soil near the Arctic Circle ( Kommedahl et al. 1988). F. equiseti has been associated with a few diseases such as cankers of sour cherry trees ( Olszak 1994), rots of cucurbit fruits in contact with soil ( Adams et al. 1987), and diseases of date palm ( Abbas et al. 1991). ...
