Modern intensive agricultural practices face numerous challenges that pose major threats to global food security. In order address the nutritional requirements of ever-increasing world population, chemical fertilizers and pesticides are applied on large scale increase crop production. However, injudicious use agrochemicals has resulted in environmental pollution leading public health hazards. Moreover, agriculture soils continuously losing their quality physical properties as well (imbalance nutrients) biological health. Plant-associated microbes with plant growth- promoting traits have enormous potential solve these play a crucial role enhancing biomass yield. The beneficial mechanisms growth improvement include enhanced nutrient availability, phytohormone modulation, biocontrol phytopathogens amelioration biotic abiotic stresses. Solid-based or liquid bioinoculant formulation comprises inoculum preparation, addition cell protectants such glycerol, lactose, starch, good carrier material, proper packaging best delivery methods. Recent developments entrapment/microencapsulation, nano-immobilization microbial bioinoculants biofilm-based biofertilizers.

How plants recruit their microbiome? New insights into beneficial interactions

Journal of Advanced Research, Journal Year: 2021, Volume and Issue: 40, P. 45 - 58

Published: Dec. 4, 2021

Research on beneficial mechanisms by plant-associated microbiomes, such as plant growth stimulation and protection from pathogens, has gained considerable attention over the past decades; however, used plants to recruit their microbiome is largely unknown.Here, we review latest studies that have begun reveal strategies in selectively recruiting how they manage exclude potential pathogens. Key Scientific concepts of Review: We examine attract microbiota main areas interaction, rhizosphere, endosphere, phyllosphere, demonstrate process occurs producing root exudates, recognizing molecules produced or distinguishing pathogens using specific receptors, triggering signals support plant-microbiome homeostasis. Second, analyzed environmental biotic factors modulate structure successional dynamics microbial communities. Finally, associated capable engaging with other synergistic microbes, hence providing an additional element selection. Collectively, this study reveals importance understanding complex network interactions, which will improve bioinoculant application agriculture, based a interacts efficiently organs under different conditions.

To date, an understanding of how plant growth-promoting bacteria facilitate growth has been primarily based on studies individual interacting with plants under different conditions. More recently, it become clear that specific soil microorganisms interact one another in consortia the collective being responsible for positive effects growth. Different attract cross-sections and fungi soil, initially composition unique root exudates from each plant. Thus, mostly those are beneficial to exclude potentially pathogenic. Beneficial bacterial not only help promote growth, these also protect a wide range direct indirect environmental stresses. Moreover, is currently possible engineer seeds contain desired strains thereby benefit next generation plants. In this way, may no longer be necessary deliver microbiota growing As we develop better microbiomes, synthetic microbiomes where compatible work together natural

Recent Advances in Bacterial Amelioration of Plant Drought and Salt Stress

Biology, Journal Year: 2022, Volume and Issue: 11(3), P. 437 - 437

Published: March 12, 2022

The recent literature indicates that plant growth-promoting bacteria (PGPB) employ a range of mechanisms to augment plant's ability ameliorate salt and drought stress. These include synthesis auxins, especially indoleacetic acid, which directly promotes growth; antioxidant enzymes such as catalase, superoxide dismutase peroxidase, prevents the deleterious effects reactive oxygen species; small molecule osmolytes, e.g., trehalose proline, structures water content within bacterial cells reduces turgor pressure; nitrogen fixation, improves exopolysaccharides, protects from loss stabilizes soil aggregates; antibiotics, stress-debilitated plants pathogens; enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase, lowers level ACC ethylene in plants, thereby decreasing stress-induced senescence. Many reports overcoming these stresses indicate most successful PGPB possess several mechanisms; however, involvement any particular mechanism protection is nearly always inferred not proven.

Crop plants are more often exposed to abiotic stresses in the current age of fast-evolving climate change. This includes exposure extreme and unpredictable changes climatic conditions, phytosanitary hazards, cultivation which results drastic losses worldwide agricultural productions. Plants coexist with microbial symbionts, some play key roles ecosystem plant processes. The application biostimulants, take advantage symbiotic relationships, is a long-term strategy for improving productivity performance, even face change-associated stresses. Beneficial filamentous fungi, yeasts, bacteria examples can boost growth, yield, nutrition stress tolerance plants. paper highlights recent information about role biostimulants their potential mitigating occurring on crop due A critical evaluation efficient use under diverse conditions also made. Currently, accessible products generally improve cultural but action mechanisms mostly unknown, benefits frequently inconsistent. Thus, further studies that could lead precisely targeted discussed.
