The Roles of Plant Growth Promoting Microbes in Enhancing Plant Tolerance to Acidity and Alkalinity Stresses

Frontiers in Sustainable Food Systems, Год журнала: 2020, Номер 4

Опубликована: Июль 10, 2020

Plant growth often occurs under a range of stressful conditions, including soil acidity and alkalinity. Hydrogen ion concentration, which determines pH the soil, regulates entire chemistry plant nutrient colloidal solutions. Beyond certain levels multiple stresses such as hydrogen toxicity, imbalance, toxicities deficiencies are induced in plants. Breeding for stress coupled with suitable agronomic practices has been way to deal this situation agriculture. However, promoting microbes (PGPM) have shown potential sustainable enhancers help environmental stresses. Considering long-term evolutionary relationships between plants microbes, it is probable that much remains unknown about benefits could be harnessed from PGPM. This article reviews current understanding alkalinity effects on various approaches or address these review further provides detailed account regarding role PGPM management, when breeding combined. Approaches already evaluated limitations because soils gradual progressive conditions. Greater exploitation regard, would interesting explore they more fashion. Future crop production will require tolerance, but also implementation microbial technologies provide enhanced tolerance stress.

PGPR in Agriculture: A Sustainable Approach to Increasing Climate Change Resilience

Frontiers in Sustainable Food Systems, Год журнала: 2021, Номер 5

Growing environmental concerns are potentially narrowing global yield capacity of agricultural systems. Climate change is the most significant problem world currently facing. To meet food demand, production must be doubled by 2050; over exploitation arable lands using unsustainable techniques might resolve demand issues, but they have negative effects. Current crop systems a major reason for changing climate through diminishing biodiversity, physical and chemical soil degradation, water pollution. The application fertilizers pesticides contribute to greenhouse gas emissions (GHG) toxic depositions. At this crucial time, there pressing need transition more sustainable practices, ones that concentrate on promoting mechanisms, which enable crops grow well in resource limited environmentally challenging environments, also develop with greater use efficiency optimum yields across wider array conditions. phytomicrobiome considered as one best strategies; better alternative agriculture, viable solution twin challenges security stability. Use phytomicrobiome, due its friendly mechanisms plant growth promotion, becoming widespread industry. Therefore, review, we emphasize contribution beneficial members, particularly rhizobacteria (PGPR), strategy improvement face change. Also, roles dwelling microbes stress amelioration, nutrient supply (nitrogen fixation, phosphorus solubilization), phytohormone along factors could affect their been discussed extensively. Lastly, limitations expansion biobased techniques, instance, perspective producers, indigenous microbial competition regulatory approval discussed. This review largely focusses importance approaches such biobased/PGPR-based our systems, especially context current conditions, almost certain worsen near future.

Insight Into the Role of PGPR in Sustainable Agriculture and Environment

Frontiers in Sustainable Food Systems, Год журнала: 2021, Номер 5

Опубликована: Июнь 30, 2021

A multitude of roles is played by microbes in food and agriculture that include nutrient cycling management, organic matter decomposition fermentation. Plant growth promoting rhizobacteria (PGPR), representing microbial groups with ability colonizing plant roots, influence through various indirect direct modes order to promote its and/or protect it from diseases or damage due insect attack. Thus, PGPR research has received renewed interest worldwide. Increasing number crop-specific are being commercialized these days. Approaches like seed-inoculation soil application either alone combination bacterial culture/product for increased availability phosphate solubilisation, potassium sulfur oxidation, nitrogen fixation, iron, copper chelation gaining popularity. Arbuscular mycorrhizal fungi (AMF) root fungal symbiont improve management abiotic stress such as phosphorus deficiency. involves production indole acetic acid (IAA), ammonia (NH 3 ), hydrogen cyanide (HCN), catalase, etc. also uptake altering the level hormone enhances surface area increasing girth shape, thereby helping absorbing more nutrients. facilitate seed germination, seedling crop yield. An array including Pseudomonas, Azospirillum, Azotobacter, Klebsiella, Enterobacter, Alcaligenes, Arthrobacter, Burkholderia, Bacillus , Serratia enhance growth. Various Pseudomonas sp. have demonstrated significant increase yield different agricultural crops, wheat. Hence, developing a successful formulation, candidate should possess characteristics high rhizosphere competence, extensive competitive saprophytic ability, enhancing ease mass production, broad-spectrum action, safety toward environment compatibility other partnering organisms.

Root ethylene mediates rhizosphere microbial community reconstruction when chemically detecting cyanide produced by neighbouring plants

Microbiome, Год журнала: 2020, Номер 8(1)

Опубликована: Янв. 18, 2020

Abstract Background Stress-induced hormones are essential for plants to modulate their microbiota and dynamically adjust the environment. Despite emphasis of role phytohormone ethylene in plant physiological response heterospecific neighbour detection, less is known about how this activated signal mediates focal rhizosphere enhance fitness. Here, using 3 years peanut ( Arachis hypogaea L.), a legume, cyanide-containing cassava Manihot esculenta Crantz) intercropping monocropping field, pot hydroponic experiments addition exogenous application soil incubation experiments, we found that ethylene, cyanide-derived signal, associated with chemical identification neighbouring microbial re-assemblage rhizosphere. Results Ethylene production roots can be triggered by cyanide plants. This gaseous alters composition re-assembles co-occurrence network shifting abundance an actinobacterial species, Catenulispora sp., which becomes keystone intercropped The re-assembled provide more available nutrients support seed production. Conclusions Our findings suggest root acts as dual role. It plays perceiving biochemical cues from interspecific neighbours, also has regulatory function mediating assembly, thereby enhancing fitness improving discovery provides promising direction develop novel strategies targeted manipulations microbiome through signals.

A Critical Review on Communication Mechanism within Plant-Endophytic Fungi Interactions to Cope with Biotic and Abiotic Stresses

Journal of Fungi, Год журнала: 2021, Номер 7(9), С. 719 - 719

Опубликована: Сен. 1, 2021

Endophytic fungi infect plant tissues by evading the immune response, potentially stimulating stress-tolerant growth. The selectively allows microbial colonization to carve endophyte structures through phenotypic genes and metabolic signals. Correspondingly, develop various adaptations symbiotic signal transduction thrive in mycorrhiza. Over past decade, regulatory mechanism of plant-endophyte interaction has been uncovered. Currently, great progress made on endosphere, especially endophytic fungi. Here, we systematically summarize current understanding colonization, molecular recognition pathways, evasion mechanisms clarify transboundary communication that homeostatic phytobiome. In this work, focus signaling mechanisms, summarizing research converge improve our
