Screenhouse and field persistence of nonpathogenic endophytic Fusarium oxysporum in Musa tissue culture plants. 2017 Mar;37(2):202-212. doi: 10.3109/07388551.2015.1130683. Kumar S., Subbarao B.L., Kumari R., Hallan V., Trivedi P.K. There have been few studies on the diversity and abundance of fungal endophytes in different tissues of Panax species. Physiol. Endosphere represents an endo-compartment within the plant tissues harboring a diverse community of microorganisms living there without developing disease symptoms or negative influence on the host plant. doi: 10.1111/j.1469-8137.2009.03160.x, PubMed Abstract | CrossRef Full Text | Google Scholar. In addition, at the genus level, Colletotrichum fungi were less abundant in the spots (25.68% in the spots and 8.62% in the non-spot area), which indicated that symbiosis with Colletotrichum fungi in the spot areas may have been inhibited. Archaeal endophytes are much less studied but have been found by DNA-based detection, such as 16S rRNA sequencing, and mostly belong to the Cenarchaea and Euryarchaea [11]. (2014). The dashed curve represents the baseline . Basic Appl. Among eight endophytes from P. ginseng seeds, two Enterobacter isolates showed the ability to solubilize phosphate and fix nitrogen [39]. The first component was used to extract the reliability [P(corr)] value of all metabolites in the OPLSDA. Taxon discrimination of the root endosphere was also very clear at the order, genus, and species levels. This site needs JavaScript to work properly. Based on the binary Jaccard algorithm, UPGMA hierarchical clustering of different samples was carried out. In some cases, a second round of semi-nested PCR with an archaea-specific primer is needed to detect them, possibly indicating very low populations inside plants [12]. Background: RT @DrPalmquist: Plants | Free Full-Text | The Endosphere Microbiome of Ginseng. . For both isolation and direct sequence analysis, all these studies showed a fungal endophyte abundance of three-quarters to almost all belonging in the Ascomycota, with much fewer numbers in the Zygomycota and Basidiomycota. sharing sensitive information, make sure youre on a federal Figure 1. Evidence thus far for archaeal endophytes in ginseng comes from a metagenomics study of DNA extracted from healthy disinfected root tissue, where 5% of the reads matched archaeal sequences, but no further description was provided [30]. The author declares no conflict of interest. The benefits was proposed to be due to increased levels of several osmoprotectants and antioxidants in virus-infected plants, thus demonstrating that plant viral infection can improve the tolerance of plants to abiotic stresses. Proc. Licensee MDPI, Basel, Switzerland. Members of the Ascomycota were also predominant among 134 fungi isolated from P. quinquefolius, with all the isolates belonging to Ascomycota (Glomerella and Cladosporium being most common), except for the Basidiomycete Scizophyllum [45]. Antifungal activity was observed among volatile organic compounds produced by the endophyte Trichoderma gamsii from P. notoginseng roots, which included dimethyl disulfide, dibenzofuran, methanethiol and ketones, that may act as fungal growth inhibitors [50]. 67, 275286. (2010). Colletotrichum spaethianum leads to leaf spots in Polygonatum odoratum (Liu et al., 2020). Thus, bacterial endophytes can enhance ginseng growth by making iron, phosphate and nitrogen more available, and quite frequently all three traits can be found in the same isolate. It appears that many bacterial endophytes have the potential to promote ginseng growth through manipulation of plant hormones. [43] used culturing to find that roots had both the highest abundance and diversity, with isolates in nine genera, seeds had the second highest abundance but third highest diversity, stems had the third highest abundance but second highest diversity, and leaves had both the lowest abundance and diversity, with isolates in only four genera. However, it is unknown if cryptic/persistent virus infections would provide plants with the same benefits. Red indicates a positive correlation between these metabolites and the microbes, blue indicates a negative correlation, and white indicates a non-significant correlation (correlation = 0). 67, 15191533. The metabolites were significantly related to 40 genera of endophytic fungi belonging to 3 phyla and 11 classes. The homogenization and sonication cycle was repeated three times, followed by incubation at 20C for 1 h and centrifugation at 12,000 rpm and 4C for 15 min. PCA and orthogonal partial least squares discriminant analysis (OPLSDA) were used to study the differences in metabolite composition among 12 samples (2 leaf parts 6 biological replicates). doi: 10.1016/j.chom.2015.04.009. The Endospheres Compressive Microvibration method represents a new era in the treatment of aesthetic and rehabilitative pathologies. Because microorganisms can regulate plant immunity and affect plant metabolism (Lee and Mazmanian, 2010; Lebeis et al., 2015; Beckers et al., 2017), the relationship between microbes and metabolites was studied. Cho K.M., Hong S.Y., Lee S.M., Kim Y.H., Kahng G.G., Lim Y.P., Kim H., Yun H.D. Regarding the analysis of plant metabolites, the metabolites of the same cluster were also significantly different between spots and non-spots, and the change in these metabolites may be the cause of the change in leaf color. A QE mass spectrometer was used to acquire MS/MS spectra on an information-dependent basis (IDB) during the LC/MS experiment. In a study of 1886 bacterial endophytes isolated from P. ginseng seedlings, there were few differences before transplanting, but there were major changes correlated with transplantation, indicating an effect of the soil environment [24]. For example, a -glucosidase-producing endophytic bacterium was isolated from P. ginseng roots and identified a Flavobacterium sp. There was greater diversity in roots compared to stems, which had greater diversity than leaves. Understanding Flowers and Flowering: An Integrated Approach. (2016). Nature 528 364382. doi: 10.1007/s00122-019-03470-6, Huang, W. J., Long, C. L., and Lam, E. (2018). doi: 10.1094/PDIS-03-20-0540-PDN [Epub ahead of print]. Some other areas where more research is needed is field trials with endophyte-treated plants grown in various environments, genomic/metagenomic analysis of endophytes, and the effects of endophytes on induced disease resistance and abiotic stress tolerance. the display of certain parts of an article in other eReaders. Effect of drought on chlorophyll fluorescence and xanthophyll cycle components in winter wheat leaves with different ages. There were 59 genera, with Trichoderma being the most common at over 10%, and only the genera Fusarium, Umbelopsis, Penicillium, Phomopsis, Phoma, Alternaria and Geomyces occurring above 4% of the isolates, all of which belonged to the Ascomycota. Compant S., Cambon M., Vacher C., Mitter B., Samad A., Sessitsch A. J. Zeaxanthin and nonphotochemical quenching in sun and shade leaves of C3 and C4 plants. The Illumina library was constructed using polymerized DNA products according to the preparation process of the Illumina genomic DNA library. It can be preliminarily speculated that the uneven colonization of endophytic fungi may have an effect on the changes in plant metabolites and the relationships between metabolites and phenotype may be mediated by changes in the composition of the microbiome. Endophytic fungal diversity: Review of traditional and molecular techniques. Diversity of bacterial endophytes in, Wei G., Chen Z., Wang B., Wei F., Zhang G., Wang Y., Zhu G., Zhou Y., Zhao Q., He M., et al. The bacterial groups belonging to the Enterobacteriaceae family with different relative abundances were detected in all the samples. Li C., Chen G., Zhang J., Bai X., Zhu P., Hou Y., Zhang X. In: Bacon C.W., White J.F., editors. 2022 Aug 9;11(16):2074. doi: 10.3390/plants11162074. Res. Jin H., Yan Z., Liu Q., Yang X., Chen J., Qin B. Diversity and dynamics of fungal endophytes in leaves, stems, and roots of. results from a variety of mechanisms, such as epidermal cells, intercellular space, mesophyll cells, chloroplast variation and crystal interaction, which strengthen the white spots in the seedlings (Wang Z. X. et al., 2016; Chen et al., 2017). Plants (Basel). While the studies differed, most often the highest abundance and diversity were observed the belowground tissues, with several differences in the endophyte genera between tissues. 1. 2022 Oct 13;13:1009395. doi: 10.3389/fpls.2022.1009395. For most plants, bacterial endophytes are primarily in the -, -, -Proteobacteria, Firmicutes and Actinobacteria [5]. Hara (1957) studied the leaf spots of 55 species of plants in 24 families and divided the causes of leaf spots into two categories, each including two types: structural types (including the epidermal type and interstitial type) and pigment types (including the chlorophyll type and pigment type). [19], Dong et al. The rhizoplane microbiome of diseased samples presented a more intense microbial network than that of healthy samples, but the endosphere microbiome showed exactly the opposite variation. Abundance often increases with root age, although diversity can decrease, possibly related to increases in potential latent fungal pathogen infections. Kb were isolated on Enterobacteriaceae selective medium and further engineered by expressing 1-aminocyclopropane-1-carboxylate (ACC) deaminase on the bacterial cell walls (designated as E5P, S1P, and KbP, respectively). Tricyrtis macropoda; chlorophyll fluorescence; diversity; metabolomics; microbiome. The results showed that the bacterial diversity of green leaf parts and spots was not significantly different and that the diversity of endophytic fungi and metabolites was different in spotted and non-spotted areas. Biotransformation of ginsenoside Rb1 to ginsenoside C-K by endophytic fungus, Wu H., Yang H.Y., You X.L., Li Y.H. Plant microbiome structure and functions are shaped by several factors, including host genotype and developmental stage, the presence or absence of diseases, and environmental conditions. Foods. The culture filtrates showed inhibitory activity against five human bacterial and three human yeast pathogens. Fig. 17, 478486. 2022 Jun 10;11(12):1707. doi: 10.3390/foods11121707. Ethyl acetate extracts of cell free filtrates of 40 endophytes from different tissues of P. ginseng were tested against six different fungal pathogens of ginseng, and the extracts of Colletotrichum pisi, F. oxysporum, F. solani, Phoma terrestris and two unidentified fungi showed antimicrobial activity against one or more of six ginseng fungal pathogens, except for C. destructans [53]. Bookshelf (2016). 51, 19471954. Although archaea and viruses have been detected in symptomless ginseng plants, little is known about them. Park SU, Lim HS, Park KC, Park YH, Bae H. J Ginseng Res. See this image and copyright information in PMC. Beijing: Science Press. isolated from P. ginseng roots used -glucosidase to convert ginsenoside Rb1 to Rd then to F2 and finally the minor ginsenoside, compound K, which only has one sugar remaining [47]. In addition, we found that the spot areas of T. macropoda can be photosynthetically normal. An endophytic T. citrinoviride from mountain-cultivated P. ginseng exhibited mycoparasitism against six ginseng pathogens, penetrating or coiling around their hyphae [54]. Epub 2021 Dec 4. Bacterial endophytes are primarily members of the Proteobacteria, Actinobacteria, Firmicutes and Bacteroidetes, and fungal endophytes are primarily members of the Ascomycota, Zygomycota and Basidiomycota. (E) Microscopic image of a longitudinal section of a spot on the blade, with a magnification of 10 10. Their abundance and diversity are generally affected by environmental and plant developmental factors similar to that of bacterial endophytes. Epub 2016 Jan 26. Peach gummosis disease has been identified as a serious challenge in Korean agriculture and has developed to become a major cause of agricultural productivity losses. Sci. Keywords: Not all rhizosphere microbes can enter plant tissues and adapt to their environment, and thus endophytes are thought to be a subpopulation of the rhizosphere microbiome. Structural variability and niche differentiation in the rhizosphere and endosphere bacterial microbiome of field grown poplar trees. Transmission of bacterial endophytes. Recent work ( 8, 9) shows that plant roots assemble two distinct microbial compartments (i.e., microbiomes) from the pool of soil microbial diversity: the rhizosphere (microbes surrounding roots) and the endosphere (microbes within roots). An official website of the United States government. 109, 10651074. USA. Microb Ecol. and transmitted securely. Populations appeared to shift over time, such as Cladosporium that was dominant in 1- to 3-year-old roots but not 4-year-old roots. MeSH This site needs JavaScript to work properly. (A) Image of fluorescence on the blade of T. macropoda. Bauer found that the photosynthetic rate of seedling leaves of ivy was lower than that of mature leaves and that the adaptability of seedlings to strong light was weaker than that of mature leaves (Bauer and Bauer, 1980).
