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

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 15

Published: Sept. 23, 2024

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.

Unravelling Changes in the Pinus radiata Root and Soil Microbiomes as a Function of Aridity

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(4)

Published: April 1, 2025

ABSTRACT Increased aridity is emerging as a key impact of climate change in terrestrial ecosystems globally. Forest biomes are particularly vulnerable to the impacts changing environmental conditions due their long‐lived and sessile nature. Microbiomes have coevolved with plants under shared fitness outcomes. However, both movement via domestication rapid pace may ability recruit microbial symbionts that support stress tolerance. This study investigates effects on tree‐root microbiome symbiosis, focusing widely planted Pinus radiata . By sampling broad geographic range diverse gradients, we reveal how aridity, soil climatic variables shape communities P. roots soils. Our findings highlight while significantly predicts community assembly, other such pH organic carbon, strongly influence bacterial diversity. Groups fungal taxa were identified conditionally present underscoring importance resilience increasingly stress. Based transition current mesic arid change, found these associated vary frequency bulk soils projected become arid. These results risk will need be recruited by means. Ecological filtering host fosters “friends benefits” relationship, wherein certain provide benefits, extension phenotypic tolerance water limitation, host. Both shaped more stochastic than deterministic assembly processes, suggesting complex interplay factors structure formation.

The Role of Phytohormones in Mediating Drought Stress Responses in Populus Species

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(8), P. 3884 - 3884

Published: April 19, 2025

Drought stress substantially impacts the development and viability of Populus spp., which are essential for forestry bioenergy production. This review summarizes describes functions phytohormones, such as abscisic acid, auxins, ethylene, in modulating physiological molecular responses to water scarcity. Drought-induced ABA-mediated stomatal closure root extension adaptation processes. Furthermore, auxin–ABA (abscisic acid) interactions augment flexibility, whereas ethylene regulates antioxidant defenses alleviate oxidative stress. The advantageous function endophytic bacteria, specifically plant growth-promoting rhizobacteria (PGPR), can drought resistance spruce trees by enhancing nutrient absorption stimulating development. Structural adaptations encompass modifications architecture, including enhanced length density, uptake efficiency. Similarly, Arbuscular Mycorrhizal Fungi (AMF) significantly enhance resilience forest trees. AMF establishes symbiotic relationships with roots, improving uptake, particularly phosphorus, during conditions. morphological alterations at root–soil interface interaction soil moisture reserves. examines complex mechanisms these hormones influence shortage, aiming offer insights into prospective techniques tolerance common tree species highlights importance hormone control influencing adaptive prominent stress, providing significant implications research practical applications sustainable agriculture.

ABSTRACT Legume species are essential components of plant diversity and affect soil biodiversity across various ecosystems. Their effect on the traits bacteria, particularly in degraded grasslands, remains unknown. This study analysed relationships among diversity, legume‐associated rhizobacterial communities Xiahe (XH) Maqu (MQ) Gansu Province, Haibei (HB) Qinghai Province Hongyuan (HY) Sichuan eastern Qinghai‐Tibetan Plateau (QTP). The index values (coverage, richness, Shannon evenness) legume were positively correlated with diversity. Several nutrients (ammonia‐nitrogen, nitrate‐nitrogen, total nitrogen, available potassium, phosphorus organic matter) enzymes (urease, sucrase, peroxidase dehydrogenase) lower HB HY than XH MQ. for was higher In contrast, geographical locations sympatric species. Additionally, showed 50% fewer positive negative associations rhizobacteria Functional Annotation Prokaryotic Taxa analysis indicated a relative abundance nitrate reduction occurred MQ, whereas nitrogen fixation at level Simpson value bacterial multifunctionality. However, negatively these parameters. Changes composition different strongly influenced by nutrients, reflecting distribution characteristics legumes alpine grasslands.
