Abstract Background The utilization of beneficial (Rhizo) bacteria, as an alternative to traditional fertilizers, has emerged eco-friendly strategy for ameliorating sustainable agricultural production. This approach aims reduce the use agrochemicals and minimize environmental pollution. Scope review provides updated insight into ecological impact plant growth-promoting rhizobacteria (PGPR), focusing on resident microbiome its potential transferability next generation plants. Conclusion In this context, PGPR are assumed alter rhizosphere by outcompeting existing taxa through nutrient deprivation, acidification environment, metabolites production, consequently, increasing copiotrophic taxa. Such modifications can maximize interactions plant-PGPR bioavailability nutrients handling diverse signaling pathways. effects within PGPR-root system adjust composition root exudates influence release bioactive molecules root, especially under stress conditions, which act signals reactivate recruit microbes in endosphere favor changes structure occur gradually over time, even if survival rate soil their re-colonization efficiency inside tissue limited. aforementioned have increase chances progeny plants growing same conditions. Establishing a comprehensive robust knowledge framework that addresses all these issues is critical significantly advancing field microbe-plant developing reliable applications PGPR.

A “love match” score to compare root exudate attraction and feeding of the plant growth-promoting rhizobacteria Bacillus subtilis, Pseudomonas fluorescens, and Azospirillum brasilense

Introduction The rhizosphere is the zone of soil surrounding plant roots that directly influenced by root exudates released plant, which select microorganisms. resulting microbiota plays a key role in health and development enhancing its nutrition or immune response protecting it from biotic abiotic stresses. In particular, growth-promoting rhizobacteria (PGPR) are beneficial members this represent great hope for agroecology, since they could be used as bioinoculants sustainable crop production. Therefore, necessary to decipher molecular dialog between PGPR order promote establishment rhizosphere, required their functions. Methods Here, ability rapeseed ( Brassica napus ), pea Pisum sativum ryegrass Lolium perenne ) attract feed three Bacillus subtilis , Pseudomonas fluorescens Azospirillum brasilense was measured compared, these responses involved microbiota. Results Our results showed differentially attracted fed PGPR. For all bacteria, were most attractive induced fastest growth, while allowed highest biomass performance generally lower, variable observed bacteria. addition, P. A. appeared respond more efficiently than B. . Finally, we proposed evaluate compatibility each plant–PGPR couple assigning them “love match” score, reflects enhance bacterial rhizocompetence. Discussion Taken together, our provide new insights into specific selection through may help effective bioinoculant rhizosphere.

Effects of salt stress on plant and rhizosphere bacterial communities, interaction patterns, and functions

Frontiers in Plant Science, Год журнала: 2025, Номер 15

Опубликована: Янв. 9, 2025

Salt stress significantly affects plant growth, and Na+ has gained attention for its potential to enhance adaptability saline conditions. However, the interactions between Na+, plants, rhizosphere bacterial communities remain unclear, hindering a deeper understanding of how contributes resilience under salt stress. This study aimed investigate mechanisms through which promotes alfalfa's adaptation by modifying communities. We examined metabolic activity community composition both bacteria treatment. Our results revealed significant changes in metabolism following addition. not only promoted growth but also induced shifts plant-associated community, increasing abundance species linked resistance Furthermore, chemical characteristics alfalfa were strongly correlated with network complexity These suggest that plays crucial role enhancing fostering beneficial rhizosphere. finding highlights leveraging plant-microbe systems improve crop productivity agricultural environments.

Salt stress alters the selectivity of mature pecan for the rhizosphere community and its associated functional traits

Frontiers in Plant Science, Год журнала: 2025, Номер 16

Introduction Salt stress is a major global environmental factor limiting plant growth. Rhizosphere bacteria, recruited from bulk soil, play pivotal role in enhancing salt resistance herbaceous and crop species. However, whether the rhizosphere bacterial community of mature tree can respond to stress, particularly saline-alkalitolerant trees, remains unexplored. Pecan ( Carya illinoinensis ), an important commercially cultivated nut tree, considered saline-alkali tolerant. Methods trees (12 years) were subjected different NaCl concentrations for 12 weeks. Collected samples included roots, leaves, fruit. Amplicon sequencing data shotgun metagenomic obtained investigated: 1) microbial communities various ecological niches pecan trees; 2) characteristic bacteria associated functional traits when suffered stress. Results discussion We characterized pecan-associated microbiome (i.e., fruit, leaf, root, soil) first time. These findings suggest that niche-based processes, such as habitat selection, drive fungal assembly tissues. reduced diversity, altered composition, shifted pecan’s selective pressure on Proteobacteria Actinobacteria . Shotgun further revealed response This study enhances our understanding tree-associated microbiomes supports theory shaping may be strategy saline-alkali-tolerant resist provide insights into tolerance potential applications, development bio-inoculants, managing saline environments agricultural contexts.
