“…1A-D). The difference in the exposure of epiphytic vs. endophytic microbiota to the external environment may contribute to our results, as the former are exposed to environmental uctuations while the endophytic microbiota is somewhat protected from these uctuations, especially changes in moisture, UV exposure, nutrient availability, and colonization by newly arriving microbial taxa [30]. Notably, the ability to maintain a high level of microbial diversity is considered a pivotal factor in preserving the stability between the microbiota and its host [31].…”

Background: Fungal decays are one of the primary causes of postharvest losses in fruit, whose onset and development are partially determined by the interactions that occur between the fruit and its resident microbiota. Harvested plums are susceptible to decay pathogens but limited research has been conducted on the microbiota of plums in storage. Therefore, in the present study the composition, diversity, and potential function of the epiphytic and endophytic microbiota of plums during storage at 25 °C and 0 °C was investigated using metagenomic sequencing. Results: Our study indicated that the diversity of the endophytic microbial community remains relatively stable in storage, while the epiphytic community undergoes a notable decline in diversity. Additionally, known pathogens, such as Lasiodiplodia, Diaporthe, Botryosphaeria, Macrophomina, Fusarium, Pseudomonas, and Pantoea, were enriched in decaying fruit, while the reported biocontrol microorganisms Pseudoalteromonas and Aureobasidium were enriched in healthy fruit stored at 25 °C. A negative association was observed between potential biocontrol species and known pathogens within the microbial community network. Notably, decay promoting Filobasidium was specifically found in decayed plums stored at 0 °C, while the beneficial microbes Novosphingobium and Bradyrhizobium were specifically found in healthy fruit. The metagenomic analysis also revealed the presence of antibiotic resistance genes (ARGs) in both endophytic and epiphytic microbial communities in plum, and were primarily associated with members of the phylum Pseudomonadota as determined by host tracking analysis. Conclusions: Findings of the study provide insight on the community dynamics that occur in the endophytic and epiphytic microbiome in plums during storage at different temperatures (25 °C and 0 °C) which can be used to develop a comprehensive strategy for the management of postharvest diseases in plum and potentially other stone fruit crops (peaches, apricots, and cherries).

“…Nonetheless, they can be latent pathogens, mutualists, commensals, temporary residents, or latent saprotrophs [38]. The majority of plant endophytes are found to be bacteria and fungi, while archaebacteria, algae, protozoa, viruses, and nematodes are rare endophytes [39]. According to modern molecular-based techniques and fossil records, the co-evaluation of endophytes has been reported to be from about 460 million years along with the plants [40,41].…”

Endophytic microbes are a ubiquitous group of plant-associated communities that colonize the intercellular or intracellular host tissues while providing numerous beneficial effects to the plants. All the plant species are thought to be associated with endophytes, majorly constituted with bacteria and fungi. During the last two decades, there has been a considerable movement toward the study of endophytes associated with coffee plants. In this review, the main consideration is given to address the coffee-associated endophytic bacteria and fungi, particularly their action on plant growth promotion and the biocontrol of pests. In addition, we sought to identify and analyze the gaps in the available research. Additionally, the potential of endophytes to improve the quality of coffee seeds is briefly discussed. Even though there are limited studies on the subject, the potentiality of coffee endophytes in plant growth promotion through enhancing nitrogen fixation, availability of minerals, nutrient absorption, secretion of phytohormones, and other bioactive metabolites has been well recognized. Further, the antagonistic effect against various coffee pathogenic bacteria, fungi, nematodes, and also insect pests leads to the protection of the crop. Furthermore, it is recognized that endophytes enhance the sensory characteristics of coffee as a new field of study.

“…These endophytes can be found in both natural and managed ecosystems [10]. Endophytes have the ability to produce beneficial metabolites like phosphorous, iron, and nitrogen from the environment, as well as growth-regulating phytohormones that help plants withstand abiotic stresses [11]. Additionally, endophytic microorganisms occupy a similar ecological niche as many plant pathogens, making them suitable candidates for biocontrol agents.…”

In this study, the biodiversity of endophytic bacteria of cultivated grape varieties from the vineyards of Primorsky Krai, Russia, was analyzed for the first time. Far Eastern grape varieties with a high level of stress resistance are a unique object of research as they are cultivated in cold and humid climates with a short summer season. Grapevine endophytic microorganisms are known as promising agents for the biological control of grapevine diseases and agricultural pests. Using genomic approaches, we analyzed the biodiversity of the endophytic bacteria and fungi in the most common grape varieties of Primorsky Krai, Russia: Vitis vinifera × Vitis amurensis cv. Adele (hybrid No. 82-41 F3), Vitis riparia × V. vinifera cv. Mukuzani (pedigree unknown), two cultivars Vitis labrusca × V. riparia cv. Alfa, and Vitis Elmer Swenson 2-7-13 cv. Prairie Star for the first time. The main representatives of the endophytic microorganisms included 16 classes of bacteria and 21 classes of fungi. The endophytic bacterial community was dominated by Gammaproteobacteria (31–59%), followed by Alphaproteobacteria (9–34%) and, to a lesser extent, by the classes Bacteroidia (9–22%) and Actinobacteria (6–19%). The dominant fungal class was Dothideomycetes (43–77%) in all samples analyzed, with the exception of the grapevine cv. Mukuzani from Makarevich, where Malasseziomycetes was the dominant fungal class. In the samples cv. Alfa and cv. Praire Star, the dominant classes were Tremellomycetes and Microbotriomycetes. A comparative analysis of the endophytic communities of the cultivated grape varieties and the wild grape V. amurensis Rupr. was also carried out. We found that 18–20% of the variance between the endophytic communities accounted for the differences between the cultivated and wild grapevines, while the factors “plant location” and “individual plants” accounted for 50–56% and 3–10% of the variance, respectively. The results of this study can be used to develop new means of biocontrol in vineyards to protect plants from abiotic stresses and pathogens.
