“…Diaporthe sp. A is a main component of the core microbiome of FRP, and species of this genus have also been reported as dominant components of the microbiome of olive and other plants (Martins et al, 2016; Noriler et al, 2018). Regarding mutualism, Diaporthe strains originally isolated from wild plant species promoted the growth of rice and tritordeum (Yang et al, 2015; Zabalgogeazcoa et al, 2018).…”

A Survey of Culturable Fungal Endophytes From Festuca rubra subsp. pruinosa, a Grass From Marine Cliffs, Reveals a Core Microbiome

et al. 2019

Festuca rubra subsp. pruinosa is a perennial grass that inhabits sea cliffs of the Atlantic coasts of Europe. In this unhospitable environment plants grow in rock crevices and are exposed to abiotic stress factors such as low nutrient availability, wind, and salinity. Festuca rubra subsp. pruinosa is a host of the fungal endophyte Epichloë festucae, which colonizes aerial organs, but its root mycobiota is unknown. The culturable endophytic mycobiota of FRP roots was surveyed in a set of 105 plants sampled at five populations in marine cliffs from the northern coast of Spain. In total, 135 different fungal taxa were identified, 17 of them occurred in more than 10% of plants and in two or more populations. Seven taxa belonging to Fusarium, Diaporthe, Helotiales, Drechslera, Slopeiomyces, and Penicillium appeared to be constituents of the core microbiome of Festuca rubra subsp. pruinosa roots because they occurred in more than 20% of the plants analyzed, and at three or more populations. Most fungal strains analyzed (71.8%) were halotolerant. The presence of Epichloë festucae in aboveground tissue was detected in 65.7% of the plants, but its presence did not seem to significantly affect the structure of the core or other root microbiota, when compared to that of plants free of this endophyte. When plants of the grass Lolium perenne were inoculated with fungal strains obtained from Festuca rubra subsp. pruinosa roots, a Diaporthe strain significantly promoted leaf biomass production under normal and saline (200 mM NaCl) watering regimes. These results suggest that the core mycobiome of Festuca rubra subsp. pruinosa could have a role in host plant adaptation, and might be useful for the improvement of agricultural grasses.

“…Microbial diversity has been explored by different researchers in the search for new biocatalysts, including the discovery of strains and enzymes with unique properties. In this quest for innovation, different environments have been approached, including forests (Pajares and Bohannan, 2016), savannas (Noriler et al, 2018), the Arctic (Malard and Pearce, 2018) and the Antarctic poles (Duarte et al, 2018), deserts (Cui et al, 2018), and finally the sea (Miao et al, 2019).…”

Biodiversity has been explored in the search for novel enzymes, including forests, savannas, tundras, deserts, and finally the sea. Marine microorganisms and their enzymes are capable of being active in high-salt concentration, large range of temperature, and high incidence of light and pressure, constituting an important source of unique biocatalysts. This review presents studies employing whole-cell processes of marine bacteria and fungi, aiming for new catalysts for different reactions in organic synthesis, such as reduction, oxidation, hydroxylation, hydrolysis, elimination, and conjugation. Genomics and protein engineering studies were also approached, and reactions employing isolated enzymes from different classes (oxidoreductases, hydrolases, lyases, and ligases) were described and summarized. Future biotechnological studies and process development should focus on molecular biology for the obtention of enzymes with interesting, fascinating and enhanced properties, starting from the exploration of microorganisms from the marine environment. This review approaches the literature about the use of marine-derived bacteria, fungi, and their enzymes for biocatalytic reactions of organic compounds, promoting a discussion about the possibilities of these microorganisms in the synthesis of different substances.

“…In this sense, studies have been directed toward bioprospecting the endophytic communities associated with the plant species found in this biome. Noriler et al (2018) evaluated the biodiversity of endophytic fungal communities associated with the medicinal plants, Stryphnodendron adstringens (from Cerrado) and Vochysia divergens (from Pantanal). Of the 1,146 endophytic fungi, 339 were isolated from S. adstrigens.…”

Chemical, diversity and biotechnological potential of endophytic fungi isolated from Brazilian Cerrado plants

This is a systematic review of scientific articles reporting the biodiversity of endophytic fungi isolated from endemic Cerrado plants in Brazil and exposes the potential applications of these microorganisms in the production of known and new metabolites. The “Portal de Periódicos” (CAPES), Science Direct, PubMed, Scielo, and Biblioteca Virtual em Saúde (BVS) databases were used. A total of 418 articles were found using the following sets of keywords: Endophytic, fungi, and Cerrado; endophytic, fungi, rupestrian, and grass lands; endophytic, fungi, Brazilian, and savanna; among these, 14 articles were selected. The articles were grouped into studies on the biodiversity of Cerrado endophytic fungi, chemical studies, and other subjects. All the articles were found to be related to the diversity present in the Cerrado of the southeastern and midwestern regions, they show high fungal biodiversity with Diaporthe genus predominant in almost all plants studied. In all the studies on the chemical diversity of endophytic fungi, new compounds or new natural products were found associated with a range of bioactivity, especially antifungal. It shows the great potential of endophytes in the production of new and bioactive secondary metabolites, as well as the unexplored chemical diversity of endophytes isolated from endemic plant species. The review shows that rare studies performed in regions where the Cerrado biome are predominant, including the central, north, and northeast regions, representing an important niche that is still unexplored.
