“…and Hypoxylon spp.) and Helotiales (e.g., Helotiaceae and Hyaloscyphaceae) are the main ONF associated with tropical and temperate orchids, respectively; Chaetothyriales, Hypocreales, Helotiales, and Capnodiales are also frequent in tropical epiphytic orchids (Bayman et al, 1997;Dearnaley et al, 2012;Oliveira et al, 2014;Govinda Rajulu et al, 2016;Jacquemyn et al, 2016a;Beltrán-Nambo et al, 2018;Novotná et al, 2018). In addition, Colletotrichum, Fusarium, and Trichoderma fungi are generally found in the roots of various orchids from tropical and temperate zones (Martos et al, 2012;Tao et al, 2013;Sufaati et al, 2016;Salazar-Cerezo et al, 2018;Sisti et al, 2019;Sarsaiya et al, 2020).…”

Orchids form mycorrhizal symbioses with fungi in natural habitats that affect their seed germination, protocorm growth, and adult nutrition. An increasing number of studies indicates how orchids gain mineral nutrients and sometime even organic compounds from interactions with orchid mycorrhizal fungi (OMF). Thus, OMF exhibit a high diversity and play a key role in the life cycle of orchids. In recent years, the high-throughput molecular identification of fungi has broadly extended our understanding of OMF diversity, revealing it to be a dynamic outcome co-regulated by environmental filtering, dispersal restrictions, spatiotemporal scales, biogeographic history, as well as the distribution, selection, and phylogenetic spectrum width of host orchids. Most of the results show congruent emerging patterns. Although it is still difficult to extend them to all orchid species or geographical areas, to a certain extent they follow the “everything is everywhere, but the environment selects” rule. This review provides an extensive understanding of the diversity and ecological dynamics of orchid-fungal association. Moreover, it promotes the conservation of resources and the regeneration of rare or endangered orchids. We provide a comprehensive overview, systematically describing six fields of research on orchid-fungal diversity: the research methods of orchid-fungal interactions, the primer selection in high-throughput sequencing, the fungal diversity and specificity in orchids, the difference and adaptability of OMF in different habitats, the comparison of OMF in orchid roots and soil, and the spatiotemporal variation patterns of OMF. Further, we highlight certain shortcomings of current research methodologies and propose perspectives for future studies. This review emphasizes the need for more information on the four main ecological processes: dispersal, selection, ecological drift, and diversification, as well as their interactions, in the study of orchid-fungal interactions and OMF community structure.

“…The fungal endophytes have a profound influence on the growth, ecology, healthiness, assembly, and multiplicity of Orchidaceae communities. Hence, information about the diverse endophytic fungi related with orchid can deliver a better perception on the connections that arise in orchids' ordinary habitats and in what way these fungi can support to orchid existence and variation [86]. One of the Orchidaceae-dominant challenges in fronting ecology and preservation is the recognition of issues influencing the spatial delivery and richness of sporadic or endangered species.…”

In the development of medicinally important Orchidaceae, the extent of fungal endophytes specificity is not presently very clear. Limited study has been available on natural products formed and its role on plant growth, defence mechanism by endophytes, and to characterize the chief treasure of bioactive molecules. Therefore, this review article presents an evaluation of the endophytes associated with Orchidaceae for physiology, metabolism, and genomics which have prominently contributed to the resurgence of novel metabolite research increasing our considerate of multifaceted mechanisms regulatory appearance of biosynthetic gene groups encoding diverse metabolites. Additionally, we presented the comprehensive recent development of biostrategies for the cultivation of endophytes from Orchidaceae and integration of bioengineered 'Genomics with metabolism' approaches with emphases collective omics as powerful approach to discover novel metabolite compounds. The Orchidaceae-fungal endophytes' biodynamics for sustainable development of bioproducts and its applications are supported in large-scale biosynthesis of industrially and pharmaceutical important biomolecules.

“…The development, ecology, longevity, alliance, as well as diversity of Orchid species, are all influenced by fungal endophytes. As a result, knowledge of the various endophytic fungi associated with orchids will provide a better understanding of the interactions that occur in orchids' natural habitats, as well as how these fungi can contribute to orchid survival or heterogeneity (Beltrán-Nambo et al 2018). Recognizing problems affecting the ecological distribution as well as an abundance of intermittent or endangered species is one of the Orchid-dominant barriers in facing biodiversity as well as sustainability.…”

“…Recognizing problems affecting the ecological distribution as well as an abundance of intermittent or endangered species is one of the Orchid-dominant barriers in facing biodiversity as well as sustainability. Furthermore, little was known about the physiological characteristics, level of interaction, or fungal sensitivity of orchid roots that are connected to those of terrestrial groups (Beltrán-Nambo et al 2018). Orchid is also the first biotic markers of network deterioration due to their multipart environmental interactions with pollinators, fungal endophytes, as well as other species.…”

Orchids, being one of nature's most magnificent as well as abundant plant species, are often a bit of an enigma because their seeds lack endosperm and rely on endophytes for seedlings, development, as well as evolution. Orchids are valued by ecologists as well as the community at large for their decorative, therapeutic, as well as nutritional content. Many orchid species have become affected and extinct as a result of growers' eagerness to obtain them. The current orchid study has concentrated on isolating and identifying mycorrhizal and non-mycorrhizal endophytes that lead to orchid growth and development and also the synthesis of useful bioactive compounds. In the large-scale biosynthetic pathway of industrially as well as pharmaceutically essential biomolecule derivatives, the biodynamics of orchid-fungal endophytes is assisted for renewable production of bio-applications and technologies. The associations between orchids as well as endophytes are the focus of the study.
