With the increase in world population, demography of humans is estimated to be exceeded and it has become a major challenge provide an adequate amount food, feed, agricultural products majorly developing countries. The use chemical fertilizers causes plant grow efficiently rapidly meet food demand. drawbacks using higher quantity or synthetic are environmental pollution, persistent changes soil ecology, physiochemical composition, decreasing productivity cause several health hazards. Climatic factors responsible for enhancing abiotic stress on crops, resulting reduced productivity. There various types biotic like salinity, drought, wind, improper temperature, heavy metals, waterlogging, different weeds phytopathogens bacteria, viruses, fungi, nematodes which attack plants, reducing crop quality. shift toward biofertilizers due all these facts, nutrition through natural processes zinc, potassium phosphorus solubilization, nitrogen fixation, production hormones, siderophore, hydrolytic enzymes protect from pathogens conditions. They that sufficient healthy development fulfill demand increasing population worldwide, eco-friendly economically convenient. This review will focus their mechanisms action, role biotic/abiotic tolerance.

The use of synthetic fungicides to control fungal diseases has growing limitations due eco-toxicological risks. Therefore, it is necessary replace or integrate high risk chemicals with safer tools for human health and environment. Consequently, research on the selection, evaluation, characterization, biocontrol agents (BCAs) consistently increased in last decades. BCA formulates, particularly some countries, are still scarce coping demand their sustainable agricultural management. To foster development utilization new effective bioformulates, there a need optimize activity, share knowledge formulation processes simplify registration procedures. Studies based molecular can significantly contribute achieve such objectives. present review provides state art plant special emphasis (i) features most studied BCAs; (ii) key strategies selection BCAs (iii); mechanisms action main (iv) metagenomic studies (v) issues constraints commercialization BCAs, (vi) perspectives diseases.

Plant Growth-Promoting Bacteria (PGPB) with Biofilm-Forming Ability: A Multifaceted Agent for Sustainable Agriculture

Diversity, Год журнала: 2023, Номер 15(1), С. 112 - 112

Опубликована: Янв. 13, 2023

Plant growth-promoting bacteria (PGPB) enhance plant growth, as well protect plants from several biotic and abiotic stresses through a variety of mechanisms. Therefore, the exploitation PGPB in agriculture is feasible it offers sustainable eco-friendly approaches to maintaining soil health while increasing crop productivity. The vital key application its effectiveness colonizing roots phyllosphere, developing protective umbrella formation microcolonies biofilms. Biofilms offer benefits PGPB, such enhancing resistance adverse environmental conditions, protecting against pathogens, improving acquisition nutrients released environment, facilitating beneficial bacteria–plant interactions. bacterial biofilms can successfully compete with other microorganisms found on surfaces. In addition, plant-associated are capable colonization sites, cycling nutrients, pathogen defenses, tolerance stresses, thereby agricultural productivity yields. This review highlights role surfaces strategies used by biofilm-forming PGPB. Moreover, factors influencing biofilm at root shoot interfaces critically discussed. will pave formulations addressing challenges related their efficacy competence for sustainability.
