Chemotaxis, the ability of motile bacteria to direct their movement in gradients attractants and repellents, plays an important role during rhizosphere colonization by rhizobacteria. The is a unique niche for plant–microbe interactions. Root exudates are highly complex mixtures chemoeffectors composed hundreds different compounds. Chemotaxis towards root initiates rhizobacteria recruitment establishment bacteria–root Over last years, progress has been made identification exudate components that play key roles process, as well cognate chemoreceptors. In first part this review, we summarized representative induce chemotaxis typical discussed structure function rhizobacterial second reviewed findings on how other root–microbe interactions promote beneficial rhizobacteria-plant leading plant growth promotion protection health. identified existing gaps knowledge future research efforts necessary close them.

Microbial Biostimulants as Response to Modern Agriculture Needs: Composition, Role and Application of These Innovative Products

Plants, Год журнала: 2021, Номер 10(8), С. 1533 - 1533

Опубликована: Июль 27, 2021

An increasing need for a more sustainable agriculturally-productive system is required in order to preserve soil fertility and reduce biodiversity loss. Microbial biostimulants are innovative technologies able ensure agricultural yield with high nutritional values, overcoming the negative effects derived from environmental changes. The aim of this review was provide an overview on research related plant growth promoting microorganisms (PGPMs) used alone, consortium, or combination organic matrices such as (PBs). Moreover, effectiveness role microbial biological tool improve fruit quality limit degradation discussed. Finally, increased use these products requires achievement accurate selection beneficial consortia, ability prepare future agriculture challenges. Hence, implementation microorganism positive list provided by EU (2019/1009), desirable.

The Role of Plant-Associated Bacteria, Fungi, and Viruses in Drought Stress Mitigation

Frontiers in Microbiology, Год журнала: 2021, Номер 12

Опубликована: Окт. 25, 2021

Drought stress is an alarming constraint to plant growth, development, and productivity worldwide. However, plant-associated bacteria, fungi, viruses can enhance resistance cope with the negative impacts of drought through induction various mechanisms, which involve biochemical physiological changes. These mechanisms include osmotic adjustment, antioxidant enzyme enhancement, modification in phytohormonal levels, biofilm production, increased water nutrient uptake as well gas exchange use efficiency. Production microbial volatile organic compounds (mVOCs) stress-responsive genes by microbes also play a crucial role acquisition tolerance. This review offers unique exploration microorganisms—plant growth promoting rhizobacteria mycorrhizae, viruses, their interactions—in microbiome (or phytobiome) whole modes action that mitigate stress.
