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.

Elucidating Mechanisms of Endophytes Used in Plant Protection and Other Bioactivities With Multifunctional Prospects

Frontiers in Bioengineering and Biotechnology, Journal Year: 2020, Volume and Issue: 8

Published: May 15, 2020

Endophytes are abundant in plants and studies continuously emanating on their ability to protect from pathogens that cause diseases especially the field of agriculture. The advantage endophytes have over other biocontrol agents is colonize plant's internal tissues. Despite this attributes, a deep understanding mechanism employed by protecting plant still required for both effectiveness commercialization. Also, there increasing cases antibiotics resistance among most causative human beings, which calls an alternative drug discovery using natural sources. present themselves as storehouse many bioactive metabolites such phenolic acids, alkaloids, quinones, steroids, saponins, tannins, terpenoids makes them promising candidate anticancer, antimalarial, antituberculosis, antiviral, antidiabetic, anti-inflammatory, antiarthritis, immunosuppressive properties others, even though primary function compounds make host resistant abiotic biotic stresses. peculiar source possible drugs. This study elucidates mechanisms different bioactivities importance humans with focus endophytic bacteria fungi.

The plant endosphere world – bacterial life within plants

Environmental Microbiology, Journal Year: 2020, Volume and Issue: 23(4), P. 1812 - 1829

Published: Sept. 21, 2020

Summary The plant endosphere is colonized by complex microbial communities and microorganisms, which colonize the interior at least part of their lifetime are termed endophytes. Their functions range from mutualism to pathogenicity. All organs tissues generally bacterial endophytes diversity composition depend on plant, organ its physiological conditions, growth stage as well environment. Plant‐associated in particular endophytes, have lately received high attention, because increasing awareness importance host‐associated microbiota for functioning performance host. Some endophyte known mostly lab assays, genome prediction few metagenome analyses; however, we limited understanding planta activities, particularly considering micro‐environments dynamics conditions. In our review, present recent findings environments, conditions colonization. Furthermore, discuss functions, interaction between plants methodological limitations research. We also provide an outlook needs future research improve role colonizing traits ecosystem functioning.

Plant Growth-Promoting Rhizobacteria for Sustainable Agricultural Production

Microorganisms, Journal Year: 2023, Volume and Issue: 11(4), P. 1088 - 1088

Published: April 21, 2023

Rhizosheric bacteria with several abilities related to plant growth and health have been denominated Plant Growth-Promoting Rhizobacteria (PGPR). PGPR promote through modes of action, be it directly or indirectly. The benefits provided by these can include increased nutrient availability, phytohormone production, shoot root development, protection against phytopathogens, reduced diseases. Additionally, help plants withstand abiotic stresses such as salinity drought produce enzymes that detoxify from heavy metals. become an important strategy in sustainable agriculture due the possibility reducing synthetic fertilizers pesticides, promoting health, enhancing soil quality. There are many studies literature. However, this review highlights used for production a practical way, making possible reduce use phosphorus nitrogen fungicides, improve uptake. This addresses topics unconventional fertilizers, seed microbiome rhizospheric colonization, microorganisms, fixation chemical solubilizing mineralizing, siderophore fungicides pesticides agriculture.

Endophytes: Colonization, Behaviour, and Their Role in Defense Mechanism

International Journal of Microbiology, Journal Year: 2020, Volume and Issue: 2020, P. 1 - 8

Published: July 30, 2020

Biotic and abiotic factors cause an enormous amount of yield economical loss. However, endophytes can play a significant role in enhancing the tolerance plants. Endophytes systematically colonize different parts host, but plants use variety defense mechanisms towards microbial infection. they have to survive oxidative environments, like Enterobacter sp. encode superoxide dismutases, catalases, hydroperoxide reductases cope up stress during colonization. On contrary, others produce subtilomycin which binds with flagella affect flg22-induced plant defense. The behavior be affected by genes hydrolase activity when come into contact host plant. lifestyle is influenced environmental factors, genotypes, as well imbalance nutrient exchange between microbe host. For instance, induction PiAMT1 root endophyte Piriformospora indica indicates depletion nitrogen plays triggering factor for activation saprotrophic program. Microbes enhance disease resistance through induced systemic (ISR), Bacillus cereus triggers ISR against Botrytis cinerea accumulation PR1 protein activates MAPK signaling WRKY53 gene expression JA/ET pathway. Similarly, Trichoderma arundinaceum produces trichodiene that affects defense-related encoding salicylic acid (SA) jasmonate (JA). Overall, vital management.

In extreme environments, the relationships between species are often exclusive and based on complex mechanisms. This review aims to give an overview of microbial ecology saline soils, but in particular what is known about interaction plants their soil microbiome, mechanisms linked higher resistance some harsh conditions. Agricultural soils affected by salinity a matter concern many countries. Soil salinisation caused readily soluble salts containing anions like chloride, sulphate nitrate, as well sodium potassium cations. Salinity harms because it affects photosynthesis, respiration, distribution assimilates causes wilting, drying death entire organs. Despite these life-unfavourable conditions, unique ecological niches inhabited extremophilic microorganisms that have specific adaptation strategies. Important traits related also associated with rhizosphere-microbiota endophytic compartments plants. For years now, there been studies dedicated isolation characterisation plants' endophytes living environments. The metabolic biotechnological potential promising.
