Endophytes are microbes (mostly bacteria and fungi) present asymptomatically in plants. Endophytic often functional that they may carry nutrients from the soil into plants, modulate plant development, increase stress tolerance of suppress virulence pathogens, disease resistance development competitor species. have been shown to: (i) obtain soils transfer to plants rhizophagy cycle other nutrient-transfer symbioses; (ii) growth development; (iii) reduce oxidative hosts; (iv) protect disease; (v) deter feeding by herbivores; (vi) Because effective functions endophytic microbes, we suggest significantly use agrochemicals (fertilizers, fungicides, insecticides, herbicides) cultivation crop The loss during domestication long-term could be remedied endophytes wild relatives crops Increasing atmospheric carbon dioxide levels efficiency due repression reactive oxygen used extract roots. © 2019 Authors.

The use of fungal entomopathogens as endophytes in biological control: a review

Mycologia, Год журнала: 2018, Номер 110(1), С. 4 - 30

Опубликована: Янв. 2, 2018

Fungal entomopathogens have been proposed as environmentally friendly alternatives to chemical control. Unfortunately, their effectiveness continues be limited by susceptibility ultraviolet (UV) light and low moisture. A relatively recent development, the use of fungal endophytes, might overcome traditional obstacles impeding widespread adoption also provide a novel alternative for management insect pests plant pathogens. In addition, some could function biofertilizers. Eighty-five papers covering 109 individual entomopathogen studies involving 12 species in six genera are reviewed. Thirty-eight 19 families were studied, with maize, common bean, tomato being most investigated. Of 85 papers, 39 (46%) examined effects endophytism on 33 17 eight orders. Thirty-four (40%) response endophytism, corresponding 20 species. Various inoculation techniques (e.g., foliar sprays, soil drenching, seed soaking, injections, etc.) effective introducing but colonization appears localized ephemeral. The field pathology will not substantially profit from dozens additional attempting introduce into wider array plants, without understand mechanisms underlying responses such consequent This review presents several areas that should receive focused attention increase probability success making this technology an

A New Approach to Modify Plant Microbiomes and Traits by Introducing Beneficial Bacteria at Flowering into Progeny Seeds

Frontiers in Microbiology, Год журнала: 2017, Номер 8

Опубликована: Янв. 22, 2017

The microbial component of healthy seeds - the seed microbiome appears to be inherited between plant generations and can dynamically influence germination, performance, survival. As such, methods optimize microbiomes major crops could have far-reaching implications for breeding crop improvement enhance agricultural food, feed, fiber production. Here, we describe a new approach modulate elite embryos concomitantly design traits mediated by microbiomes. Specifically, discovered that introducing endophyte Paraburkholderia phytofirmans PsJN flowers parent plants drive its inclusion in progeny microbiomes, thereby inducing vertical inheritance offspring generation. We demonstrated introduction monocot dicot species consequential modifications composition growth wheat, illustrating potential role novel seed-based determining traits.

Fungal endophytes for sustainable crop production

FEMS Microbiology Ecology, Год журнала: 2016, Номер 92(12), С. fiw194 - fiw194

Опубликована: Сен. 12, 2016

This minireview highlights the importance of endophytic fungi for sustainable agriculture and horticulture production. Fungal endophytes play a key role in habitat adaptation plants resulting improved plant performance protection against biotic abiotic stresses. They encode vast variety novel secondary metabolites including volatile organic compounds. In addition to protecting pathogens pests, selected fungal have been used remove animal toxicities associated with temperate grasses, create corn rice that are tolerant range stresses, management post-harvest control. We argue practices breeding, seed treatments agriculture, often caused by poor knowledge endophytes, among reasons loss endophyte diversity domesticated also accounts reduced effectiveness some strains confer benefits. provide recommendations on how mitigate these negative impacts modern agriculture.
