The mycobiota of tomato and cucumber plants cultivated under covered conditions was studied according to species composition, specific gravity of phytopathogens and endophytes, as well as ecophysiological characteristics of recorded fungi. It became clear that a total of 43 species of fungi participate in the formation of the mycobiota of the mentioned plants, of which 33 are phytopathogens, 6 are endophytes, and the status of 4 species is unknown. Although 15 species of phytopathogens are involved in the formation of the mycobiota of tomato and 8 species of cucumber, 10 species are involved in the formation of the phytopathogenic mycobiota of both plants. It became clear that the spread rate of the disease caused by these phytopathogens is 5.4-7.7% in tomato and 7.6-8.9% in cucumber. Although the noted fungi are characterized by similar indicators according to their ecophysiological characteristics, they are included in species with different characteristics (alcotolerant, microaerophilic, etc.). Endophytes include species that have a positive effect on the growth and productivity of both plants, among which the fungus Trichoderma harzianum AEF-2024 is considered more active. Thus, the treatment of plant seeds with the culture solution obtained from the mushroom in Çapek medium for 5 days and diluted 50 times has a positive effect on both the morphometric dimensions of the plants and the productivity.

My paper is one of Forest Pathology’s most-read!

Wiley Publishing just acknowledged me for having one of the top downloaded papers in Forest Pathology. Thanks to all you forest pathologists out there reading about fungal endophytes in Sitka spruce trees! Read the paper here.

Endophytic Microbiome Population from Moringa oleifera Leaves Collected in Three Localities at Pernambuco State, Northeast Brazil | Chapter 07 | Theory and Applications of Microbiology and Biotechnology Vol. 1

Aims: This work investigated the population density of endophytic microorganisms from Moringa oleifera leaves collected in three localities at the State of Pernambuco (northeastern Brazil): Urban (campus from the Federal University of Pernambuco, UFPE) and forest (botanical garden) areas at Recife city and an urban area (industrial district) at Caruaru city.

Place and Duration of Study: Department of Antibiotics and Department of Biochemistry from Federal University of Pernambuco, during four years.

Methodology: Sodium hypochlorite was used to disinfect the leaves, which were macerated in PBS buffer and separately sowed on seven culture media supplemented with antibacterial or antifungal agents.

Results: The majority of endophytes isolated were bacteria and the highest density was found in leaves from the forest area. Regarding to fungi isolation, there was no statistical difference between the density in leaves from UFPE campus and the botanical garden while no fungal isolates was obtained from leaves collected in Caruaru. The highest diversity of endophytes was found in the leaves from the botanical garden, with 111 different isolates. A total of 71, 94 and 50 bacterial isolates were obtained from leaves of UFPE campus, botanical garden and Caruaru, respectively. The number of fungal isolates were 17 (UFPE campus) and 12 (botanical garden).

Conclusion: In conclusion, the methodology employed in this work was effective for the isolation of endophytes; it is still worth to mention that climatic and geographical conditions may interfere in density and diversity of endophytes from M. oleifera leaves.

...Perry calls Indigo Ag’s solution to that problem “probably the key to our early technical success, that allowed us to leapfrog everybody else.” One of the company’s most important scientific insights, he explains, “was that plants have already done this experiment for us. The ancestors of these plants have been growing in this soil for 200 million years. Every single one of them has sampled those microbes and evolved ways of incorporating the ones that are helpful and rejecting the ones that are potentially harmful. And so, we can leverage those 200 million years of experiments by just looking inside the plant….It is a super simple insight, but nobody else was thinking about it that way.” ...new technologies focused on the health and productivity of plants will lead to an agricultural system that is better for the environment, better for humans, and better for farmers. “That is what I got into this for,” he says. “If we can solve those things, the positive impact on the world would be enormous.” Agriculture already uses 70 percent of the world’s fresh water. Fertilizers have led to chemical pollution of aquatic environments and soil degradation. “Roughly a third of greenhouse-gas emissions come from agriculture or the products that are ultimately consumed by agriculture,” Perry says. Most of the people who live in poverty today are among the billion and half people who work in agriculture. “Those three goals—of improving human health, of improving environmental sustainability, and making farming a living wage—are three of the most important things I think we can do.”

...it seems reasonable to propose that even the maximal estimates of endophyte diversity (i.e. four endophytes per plant species) have been conservative. However, even if there were only 1 million endophytic fungi in plants, that would still account for 1 in 14 or even 1 in 10 species of life.

Natural bacteria, fungi found in plants boost crop yields without pesticides

Preface by Cathy Geibel TLB writer/reporter

This is yet another company that gives me hope for the future. Imagine using naturally occurring organisms rather than pesticides and herbicides! The claim is this can put Monsanto and other biotech companies out of business, I truly hope so. Because Monsanto’s decimation of this planet must end, and end NOW!
