“…In addition, endophytic bacteria may play a role in soil fertility through phosphate solubilization and nitrogen fixation (Nimaichand et al 2016). The beneficial microbes associated with the medicinal plant that could positively affect plant growth is highly impressive due to their species diversity and probiotic biosynthesis (Wicaksono et al 2017). Endophytes colonizing inner plant tissues were reported to produced various biological metabolites, which could improve plant growth and enhance stress tolerance (Bordiec et al 2011).…”

The purpose of this study was to investigate the composition, diversity, distribution, and growth promotion activity of endophytic bacteria isolated from L. ruthenicum Murr. Consequently, a total of 109 endophytic bacteria affiliated to 3 phyla, 12 orders and 36 genera were isolated using nine different selective media, from which, Actinobacteria was the dominant taxon containing seven orders at the phylum level; Micrococcales showed the highest diversity containing 12 genera at the family level. Based on PAST and SPSS analysis, species diversity and abundance were mostly isolated from nutritious soil condition (22 genera) and root tissue (27 genera). Furthermore, growth phase showed significant effect on the endophytic bacteria community (28 genera at dormancy and 17 genera at fluorescence stage). With regard to ex situ plant growth-promoting activities, Streptomyces dominated and exhibited broad ability in terms of their potential to grow on nitrogen-free media, synthesize cellulase and lipase enzymes. Characterization of potential plant-beneficial traits indicate that endophytic bacteria exhibited a number of positive activities, including potential diazotrophy (n = 66), phosphate-solubilizing (n = 6), production of lipase (n = 21) and cellulose (n = 35). Two strains, representing Bacillus sp. EGI 63071 and EGI 63106, were found to be effective in promoting the growth of Triticum aestivum (wheat: Xindong No.18) seedling under salt stress conditions.

“…Differently, Santos et al (2016) reported that the volatiles compounds of B. subtilis of commercial products (Rizos and Rizolyptus) inhibited the mycelial growth of D. macrodidyma, ranging from 29.5% to 69.1%. Wicaksono et al (2017) also reported inhibition of mycelial growth by volatile compounds higher than 30% in Neofusicocumum ribis employing Pseudomonas sp. W1R33, W7R11, and W7R13.…”

“…Also, Ferreira et al (1991) reported a reduction of 88% in the mycelial growth of Eutypa lata using a B. subtilis strain isolated in pruning wounds of the vine. Inhibition of mycelial growth over 50% of Botryosphaeriaceous species causing grapevine trunk diseases were verified by Wicaksono et al (2017) by diffusible compounds of Pseudomonas sp. I2R21 and Burkholderia sp.…”

Decline and death of young vines is a worldwide problem for viticulture that may lead to economic loss. Fungal pathogens have been associated with trunk and root diseases, including the black foot disease that affects the performance of the vineyards. Fungicides have not worked efficiently to control the disease and alternative methods should be investigated. We evaluated the potential of Bacillus subtilis strain F62 for controlling the disease caused by different strains in grapevine rootstocks 1103P (Vitis berlandieri × V. rupestris) and SO4 (V. berlandieri × V. riparia). The in vitro antagonism of B. subtilis F62 was evaluated on mycelial growth, by diffusible and volatile compounds, and conidia germination, by bacterial suspension and cell-free filtrate. In the in vivo assay, cuttings and micropropagated rootstocks were submitted to four different treatments: control, Bac (B. subtilis inoculation), Pat (pathogen inoculation) and Bac + Pat. According to our results, the bioagent was able to inhibit the mycelial growth of all the three fungal isolates by diffusible compounds and conidial germination by bacterial suspension and cell-free filtrate. In the in vivo assay, cuttings of SO4 treated with B. subtilis F62 showed higher shoot nodes and length of primary shoot, while cuttings of 1103P had a longer primary shoot. In micropropagated plants, B. subtilis F62 promoted plant growth in both rootstocks and reduced the frequency of D. macrodidyma re-isolation to 24.6% in SO4 and 29.5% in 1103P. The results demonstrated the potential of B. subtilis F62 on plant growth promotion and in the biocontrol of black foot disease on micropropagated plants and cuttings of grapevine rootstocks 1103P and SO4.

The Role of the Endophytic Microbiome in the Grapevine Response to Environmental Triggers

et al. 2019

Endophytism within Vitis represents a topic of critical relevance due to the multiple standpoints from which it can be approached and considered. From the biological and botanical perspectives, the interaction between microorganisms and perennial woody plants falls within the category of stable relationships from which the plants can benefit in multiple ways. The life cycle of the host ensures persistence in all seasons, repeated chances of contact, and consequent microbiota accumulation over time, leading to potentially high diversity compared with that of herbaceous short-lived plants. Furthermore, grapevines are agriculturally exploited, highly selected germplasms where a profound man-driven footprint has indirectly and unconsciously shaped the inner microbiota through centuries of cultivation and breeding. Moreover, since endophyte metabolism can contribute to that of the plant host and its fruits’ biochemical composition, the nature of grapevine endophytic taxa identities, ecological attitudes, potential toxicity, and clinical relevance are aspects worthy of a thorough investigation. Can endophytic taxa efficiently defend grapevines by acting against pests or confer enough fitness to the plants to endure attacks? What are the underlying mechanisms that translate into this or other advantages in the hosting plant? Can endophytes partially redirect plant metabolism, and to what extent do they act by releasing active products? Is the inner microbial colonization necessary priming for a cascade of actions? Are there defined environmental conditions that can trigger the unleashing of key microbial phenotypes? What is the environmental role in providing the ground biodiversity by which the plant can recruit microsymbionts? How much and by what practices and strategies can these symbioses be managed, applied, and directed to achieve the goal of a better sustainable viticulture? By thoroughly reviewing the available literature in the field and critically examining the data and perspectives, the above issues are discussed.
