“…A Diaporthe fungal endophyte from a wild grass, Festuca rubra, improves the growth and salinity tolerance of domesticated grasses [ 48 ]. In addition, endophytes can be considered a source of bioactive compounds, such as alkaloids, benzopyranones, chinones, flavonoids, phenolic acids, quinones, steroids, terpenoids, tetralones, and xanthones [ 49 ]. Thus, endophytic microbes from wild plants have great potential for application in agriculture and represent an important source of various compounds with valuable biological activities.…”

Many grape endophytic microorganisms exhibit high potential for suppressing the development of grape diseases and stimulating grapevine growth and fitness, as well as beneficial properties of the crop. The microbiome of wild grapevines is a promising source of biocontrol agents, which can be beneficial for domesticated grapevines. Using next-generation sequencing (NGS) and classical microbiology techniques, we performed an analysis of bacterial and fungal endophytic communities of wild grapevines Vitis amurensis Rupr. and Vitis coignetiae Pulliat growing in the Russian Far East. According to the NGS analysis, 24 and 18 bacterial taxa from the class level were present in V. amurensis and V. coignetiae grapevines, respectively. Gammaproteobacteria (35%) was the predominant class of endophytic bacteria in V. amurensis and Alphaproteobacteria (46%) in V. coignetiae. Three taxa, namely Sphingomonas, Methylobacterium, and Hymenobacter, were the most common bacterial genera for V. amurensis and V. coignetiae. Metagenomic analysis showed the presence of 23 and 22 fungi and fungus-like taxa of class level in V. amurensis and V. coignetiae, respectively. The predominant fungal classes were Dothideomycetes (61–65%) and Tremellomycetes (10–11%), while Cladosporium and Aureobasidium were the most common fungal genera in V. amurensis and V. coignetiae, respectively. A comparative analysis of the endophytic communities of V. amurensis and V. coignetiae with the previously reported endophytic communities of V. vinifera revealed that the bacterial biodiversity of V. amurensis and V. coignetiae was similar in alpha diversity to V. vinifera’s bacterial biodiversity. The fungal alpha diversity of V. amurensis and V. coignetiae was statistically different from that of V. vinifera. The beta diversity analysis of bacterial and fungal endophytes showed that samples of V. vinifera formed separate clusters, while V. amurensis samples formed a separate cluster including V. coignetiae samples. The data revealed that the endophytic community of bacteria and fungi from wild V. amurensis was richer than that from V. coignetiae grapes and cultivated V. vinifera grapes. Therefore, the data obtained in this work could be of high value in the search for potentially useful microorganisms for viticulture.

“…They have shown unique intrinsic lifestyles and mechanisms to evade host defence reactions and bypass the host immune system to enable asymptomatic proliferation within the host [13]. Reports by Singh et al [14] and Tidke et al [15] show that endophytes can synthesize secondary metabolites such as peptides, quinolons, polyketones,alkaloids, phenolic compounds, steroids, avonoids, terpenoids, azadirachtin and siderophores that have antimicrobial and insecticidal properties. Similarly, endophytes have unique enzyme systems that are responsible for synthesizing enzymes such as amylases, pectinases, laccases, cellulases, proteinases and lipases that arrest the proliferation and attack by microbial and insect pathogens [16,17].…”

Plants have diverse and vast niches colonized by endophytic microorganisms that promote the well being of host plant. These microbes inhabit internal plant tissues with no signs of ill health. Bacterial endophytes from many plants have been isolated and characterized due to their beneficial roles however their diversity in leguminous plants still remain unexploited. Diversity of bacterial endophytes isolated from L. diversifolia, S. sesban and C. Salothyrsus were assessed using morphological and molecular characteristics. A total of 27 pure isolates were recovered from C. Calothyrsus, L. diversifolia and S. sesban constituting 44.4%, 31.8% and 23.8% from the leaves, stems and roots respectively. The isolates differentiated into Gram positive and negative with rods and spherical shapes. Analysis of 16S rRNA gene sequence revealed 10 closely related bacterial genera that consisted of Bacilli (33.3%), Staphylococcus (22.2%), Alcaligens (11.2%), Xanthomonas and Sphingomonas (47.4 %). Others included Enterobacteria, Pantoea, Acinetobacter, Pseudomonas and Bacterium. These results indicate the presence of high diversity of endophytic bacteria associated with the different parts of L. diversifolia, S. sesban and C. salothyrsus growing in western Kenya.
