From Microbiome to Traits: Designing Synthetic Microbial Communities for Improved Crop Resiliency

Frontiers in Plant Science, Journal Year: 2020, Volume and Issue: 11

Published: Aug. 27, 2020

Plants teem with microorganisms, whose tremendous diversity and role in plant-microbe interactions are being increasingly explored. Microbial communities create a functional bond their hosts express beneficial traits capable of enhancing plant performance. Therefore, significant task microbiome research has been identifying novel microbial that can contribute to crop productivity, particularly under adverse environmental conditions. However, although knowledge exponentially accumulated recent years, few methods regarding the process designing inoculants for agriculture have presented. A recently introduced approach is use synthetic (SynComs), which involves applying concepts from both ecology genetics design inoculants. Here, we discuss how translate this rationale delivering stable effective by tailoring SynComs microorganisms possessing robust colonization, prevalence throughout development specific functions plants. Computational methods, including machine learning artificial intelligence, will leverage approaches screening microbes while improving determining best combination desired phenotype. We focus on advances deepen our critically prospect using resiliency against stressful

Biological Control of Plant Diseases: An Evolutionary and Eco-Economic Consideration

Pathogens, Journal Year: 2021, Volume and Issue: 10(10), P. 1311 - 1311

Biological control is considered as a promising alternative to pesticide and plant resistance manage diseases, but better understanding of the interaction its natural societal functions necessary for endorsement. The introduction biological agents (BCAs) alters among plants, pathogens, environments, leading physical cascades that influence pathogen fitness, health, ecological function. These interrelationships generate landscape tradeoffs social control, comprehensive evaluation benefits costs across farmer perspectives required ensure sustainable development deployment approach. Consequently, there should be shift disease philosophy from single concept only concerns crop productivity multifaceted concerning productivity, function, acceptability, economical accessibility. To achieve these goals, attempts make develop "green" BCAs used dynamically synthetically with other approaches in an integrated management scheme, evolutionary biologists play increasing role formulating strategies. Governments public also implementation strategies supporting positive externality.

Phosphate bacterial solubilization: A key rhizosphere driving force enabling higher P use efficiency and crop productivity

Journal of Advanced Research, Journal Year: 2021, Volume and Issue: 38, P. 13 - 28

Published: Aug. 23, 2021

Increasing crop production to feed a growing population has driven the use of mineral fertilizers ensure nutrients availability and fertility agricultural soils. After nitrogen, phosphorus (P) is second most important nutrient for plant growth productivity. However, P in soils often limited because strongly binds soil particles divalent cations forming insoluble P-complexes. Therefore, there constant need sustainably improve availability. This may include, among other strategies, application microbial resources specialized cycling, such as phosphate solubilizing bacteria (PSB). P-mediating bacterial component can biological production, should be integrated well-established formulations enhance efficiency P. importance fertilization, including both organic rock (RP) aiming its agronomic within an nutrition system where profitability PSB synergistically occur. The purpose this review discuss critically contribution concert with fertilizers, specific focus on RP. We also highlight bioformulations being sustainable approach fertilizer production. first recognize sustain which requires rational screening evaluation enabling accurate assessment effects alone intertwined interaction roots. Furthermore, we propose new research ideas about development based particular strains exhibiting synergetic

Root Exudates: Mechanistic Insight of Plant Growth Promoting Rhizobacteria for Sustainable Crop Production

Frontiers in Microbiology, Journal Year: 2022, Volume and Issue: 13

Published: July 14, 2022

The breaking silence between the plant roots and microorganisms in rhizosphere affects growth physiology by impacting biochemical, molecular, nutritional, edaphic factors. components of root exudates are associated with microbial population, notably, growth-promoting rhizobacteria (PGPR). information accessible to date demonstrates that PGPR is specific plant's roots. However, inadequate for developing bio-inoculation/bio-fertilizers crop concern, satisfactory results at field level. There a need explore perfect candidate meet yield. functions their chemotaxis mobility toward triggered cluster genes induced exudates. Some reports have indicated benefit productivity, yet methodical examination rhizosecretion its consequences phytoremediation not been made. In light afore-mentioned facts, present review, mechanistic insight recent updates on recruitment improve production level methodically addressed.

Benefits to Plant Health and Productivity From Enhancing Plant Microbial Symbionts

Frontiers in Plant Science, Journal Year: 2021, Volume and Issue: 11

Published: April 12, 2021

Plants exist in close association with uncountable numbers of microorganisms around, on, and within them. Some these endophytically colonize plant roots. The colonization roots by certain symbiotic strains plant-associated bacteria fungi results plants performing better than whose are colonized only the wild populations microbes. We consider here crop inhabited introduced organisms, referring to them as Enhanced Plant Holobionts (EPHs). EPHs frequently exhibit resistance specific diseases pests (biotic stresses); abiotic stresses such drought, cold, salinity, flooding; enhanced nutrient acquisition use efficiency; increased photosynthetic capability; ability maintain efficient internal cellular functioning. microbes described generate effects part through their production Symbiont-Associated Molecular Patterns (SAMPs) that interact receptors cell membranes. Such interaction transduction systemic signals cause plant-wide changes plants’ gene expression physiology. EPH arise not from plant-microbe interactions, but also microbe-microbe interactions like competition, mycoparasitism, antibiotic production. When root shoot growth a consequence endophytes, this increases yield plants. An additional benefit growing larger systems having greater capability is sequestration atmospheric CO 2 . This transferred where sequestered C, exudation or decomposition, becomes total soil carbon, which reduces global warming potential atmosphere. Forming requires selection introduction appropriate microorganisms, performance affected delivery management practices.
