“…There are various kinds of bioactive metabolites produced by endophytes, and the method of using them as biological control agents to replace chemical pesticides in disease control is getting more and more attention 172 . However, there are still some problems that remain to be solved.…”

“…Endophytes are an important resource to develop and to solve the problems of disease control, quality, and safety of fruit and vegetables. The effect of endophytes on plants to enhance resistance and promote plant growth has been clearly studied; and compared with other isolates, endophytes are capable of stimulating and activating the stress response of the host plant firmly and promptly 172 . Therefore, as a biological control agent, endophytes should be an important part of the control system of postharvest fruit and vegetables.…”

Food loss of fruit and vegetables caused by postharvest diseases is a major issue worldwide. The method used to prevent and control postharvest diseases is usually to use chemical fungicides, but long‐term and large‐scale use will make the pathogens resistant and potentially have a negative impact on human health and the ecological environment. Therefore, finding a safe and effective biological control method instead of chemical control is a hot research topic in recent years. Endophytes, colonizing plants asymptomatically, can promote the growth of the hosts and enhance their resistance. The use of endophytes as biological control agents for postharvest diseases of fruit and vegetables has attracted increasing attention in the last 20 years. Compared with chemical control, endophytes have the advantages of being more environmentally friendly, sustainable, and safer. However, there are relatively few relevant studies, so herein we summarize the available literature. This review focuses mainly on the recent progress of using endophytes to enhance the resistance of postharvest fruit and vegetables to diseases, with the emphasis on the possible mechanisms and the potential applications. Furthermore, this article suggests future areas for study using antagonistic endophytes to prevent and control fruit and vegetable postharvest diseases: (i) screening more potential broad‐spectrum anti‐pathogen endophytes and their metabolic active substances by the method of macrogenomics; (ii) elucidating the underlining molecular mechanism among endophytes, harvested vegetables and fruit, pathogens, and microbial communities; (iii) needing more application research to overcome the difficulties of commercialization practice. © 2020 Society of Chemical Industry

“…In terms of their ecological functions, lichens fix atmospheric nitrogen into nitrates that plants use as nutrients [ 10 ]. Mycorrhizal fungi improve plant primary production by facilitating their nutrient and water uptake [ 11 ], and endophytic fungi act as biocontrols protecting plants from pathogen infections [ 12 ]. Wood-decaying fungi are primary agents of deadwood decomposition, and thus they play a pivotal role in the biogeochemical cycle of carbon and nitrogen [ 13 ].…”

Fungal communities decline with urbanization—more in air than in soil

et al. 2020

Increasing evidence suggests that degradation of biodiversity in human populated areas is a threat for the ecosystem processes that are relevant for human well-being. Fungi are a megadiverse kingdom that plays a key role in ecosystem processes and affects human well-being. How urbanization influences fungi has remained poorly understood, partially due to the methodological difficulties in comprehensively surveying fungi. Here we show that both aerial and soil fungal communities are greatly poorer in urban than in natural areas. Strikingly, a fivefold reduction in fungal DNA abundance took place in both air and soil samples already at 1 km scale when crossing the edge from natural to urban habitats. Furthermore, in the air, fungal diversity decreased with urbanization even more than in the soil. This result is counterintuitive as fungal spores are known to disperse over large distances. A large proportion of the fungi detectable in the air are specialized to natural habitats, whereas soil fungal communities comprise a large proportion of habitat generalists. The sensitivity of the aerial fungal community to anthropogenic disturbance makes this method a reliable and efficient bioindicator of ecosystem health in urban areas.

“…Biotechnologically, endophytic microbiota function as an abundant source for production of various secondary metabolites, including alkaloids, terpenes, steroids, polyketides, quinones, iso-coumarins, esters, flavonoids, and lactones, et al [15,16]. Possessing antibacterial, antifungal, insecticidal, antioxidant, cytotoxic and anticancer properties [17], these microbiota-derived compounds enrich the chemical diversity of biologically active molecules and provide new ways for drug development [18]. More interestingly, some plant endophytic fungi were reported to produce secondary metabolites with high medicinal value, such as paclitaxel, camptothecin, et al [8,18], which provide solutions to the shortage of medical resources and ecological damage caused by the slow growth and shortage of certain medical plants, and can be used as a bioengineering tool for drug production [19].…”

Implications of endophytic microbiota in Camellia sinensis : a review on current understanding and future insights

et al. 2020

Endophytic fungi and bacteria are the most ubiquitous and representative commensal members that have been studied so far in various higher plants. Within colonization and interaction with their host plants, endophytic microbiota are reportedly to modulate not only the host's growth but also holobiont resilience to abiotic and biotic stresses, providing a natural reservoir and a promising solution for sustainable agricultural development challenged by global climate change. Moreover, possessing the talent to produce a wide array of high-value natural products, plant endophytic microbiota also serve as an alternative way for novel drug discovery. In this review, tea, one of the world's three largest nonalcoholic beverages and a worldwide economic woody crop, was highlighted in the context of endophytic microbiota. We explore the recent studies regarding isolation approaches, distribution characteristics and diversity, and also biological functions of endophytic microbiota in Camellia sinensis (L.) O. Kuntze. Profoundly, the future insight into interaction mechanism between endophytic microbiota and tea plants will shed light on in-depth exploration of tea microbial resources.
