Опубликована: Май 25, 2020

Plant-parasitic-nematodes represent a major threat to the agricultural production of different crops worldwide. Due high toxicity chemical nematicides, it is necessary develop new control strategies against nematodes. In this respect, filamentous fungi can be an interesting biocontrol alternative. The genus Trichoderma, mycorrhizal and endophytic are main groups studied used as biological agents (BCAs) nematodes resistance inducers. They able reduce damage caused by plant-parasitic directly parasitism, antibiosis, paralysis lytic enzymes. But they also minimise harm space resource-competition, providing higher nutrient water uptake plant, or modifying root morphology, and/or rhizosphere interactions, that constitutes advantage for plant-growth. Besides, induce activating hormone-mediated (salicylic jasmonic acid, strigolactones among others) plant-defence mechanisms. Additionally, alteration transport defence components through plant synthesis secondary metabolites enzymes contribute enhancing defences. Therefore, use mentioned BCAs promising durable strategy in agriculture

Endophytic fungi are found in most, if not all, plant species on the planet. They colonise inner tissues without causing symptoms of disease, thus providing benefits to host while also benefiting from this interaction. The global concern for development more sustainable agriculture has increased recent years, and research been performed decipher ecology explore potential endophytic interactions growth. To date, many studies point positive aspects colonisation, review, such is summarised based direct (acquisition nutrients phytohormone production) indirect (induced resistance, production antibiotics secondary metabolites, siderophores protection abiotic biotic stresses) colonisation.

The Potential Application of Endophytes in Management of Stress from Drought and Salinity in Crop Plants

Microorganisms, Год журнала: 2021, Номер 9(8), С. 1729 - 1729

Endophytic microorganisms present inside the host plant play an essential role in fitness, nutrient supply and stress tolerance. Endophytes are often used sustainable agriculture as biofertilizers, biopesticides inoculants to mitigate abiotic stresses including salinity, drought, cold pH variation soil. In changing climatic conditions, create global challenges achieve optimum crop yields agricultural production. Plants experience conditions that involve endogenous boosting of their immune system or overexpression defensive redox regulatory systems with increased reactive oxygen species (ROS). However, rising factors overwhelm natural protection plants, which leads massive internal oxidative damage death. integral partner hosts have been shown via modulating local systemic mechanisms producing antioxidants counteract ROS plants. Advancements omics other technologies made, but potential application endophytes remains largely unrealized. this review article, we will discuss diversity, population interaction plants well applications management.

Abstract Globally, substantial research into endophytic microbes is being conducted to increase agricultural and environmental sustainability. Endophytic such as bacteria, actinomycetes, fungi inhabit ubiquitously within the tissues of all plant species without causing any harm or disease. Endophytes form symbiotic relationships with diverse can regulate numerous host functions, including resistance abiotic biotic stresses, growth development, stimulating immune systems. Moreover, endophytes play a dominant role in nutrient cycling, biodegradation, bioremediation, are widely used many industries. have stronger predisposition for enhancing mineral metal solubility by cells through secretion organic acids low molecular weight metal-specific ligands (such siderophores) that alter soil pH boost binding activity. Finally, synthesize various bioactive compounds high competence promising candidates new drugs, antibiotics, medicines. Bioprospecting novel secondary metabolites has given momentum sustainable agriculture combating stresses. Biotechnological interventions aid played pivotal crop improvement mitigate stress conditions like drought, salinity, xenobiotic compounds, heavy metals. Identification putative genes from conferring tolerance diseases, apart those involved accumulation degradation contaminants, could open avenues development.

Fungal Endophytes to Combat Biotic and Abiotic Stresses for Climate-Smart and Sustainable Agriculture

Frontiers in Plant Science, Год журнала: 2022, Номер 13

Опубликована: Июль 5, 2022

The agricultural sustainability concept considers higher food production combating biotic and abiotic stresses, socio-economic well-being, environmental conservation. On the contrary, global warming-led climatic changes have appalling consequences on agriculture, generating shifting rainfall patterns, high temperature, CO2, drought, etc., prompting stress conditions for plants. Such stresses abandon plants to thrive, demoting productivity ultimately hampering security. Though issues are natural cannot be regulated, can still enabled endure these abnormal conditions, reinforcing resilience in an eco-friendly fashion by incorporating fungal endophytes. Endophytic fungi a group of subtle, non-pathogenic microorganisms establishing mutualistic association with diverse plant species. Their varied host under dynamic environments boosts endogenic tolerance mechanism against various via overall modulations local systemic mechanisms accompanied antioxidants secretion, ample enough scavenge Reactive Oxygen Species (ROS) hence, coping over-expression defensive redox regulatory system as aversion stressed condition. They also reported ameliorate toward mitigation elevate phytohormone levels forging them worthy used biocontrol agents biofertilizers pathogens, promoting crop improvement soil improvement, respectively. This review summarizes present-day conception endophytic fungi, their diversity crops, molecular behind resistance climate-resilient aided sustainable agriculture.

Endophytic bacteria are mainly present in the plant’s root systems. improve plant health and sometimes necessary to fight against adverse conditions. There is an increasing trend for use of bacterial endophytes as bio-fertilizers. However, new challenges also arising regarding management these newly discovered endophytes. Plant growth-promoting exist a wide host range part their microbiome, proven exhibit positive effects on growth. communities within hosts dynamic affected by abiotic/biotic factors such soil conditions, geographical distribution, climate, species, plant-microbe interaction at large scale. Therefore, there need evaluate mechanism endophytes’ with plants under field conditions before application. Bacterial have both beneficial harmful impacts but exact poorly understood. A basic approach exploit potential genetic elements involved endophytic lifestyle compare genomes rhizospheric bacteria. In this mini-review, we will be focused characterize diversity dynamics endophyte different plants.
