Pinus pinaster Aiton (maritime pine) stands are suffering a generalized deterioration due to different decline episodes throughout all its distribution area. It is well known that external disturbances can alter the plant associated microbiota and metabolome, which ultimately entail disruption of normal growth hosts. Notwithstanding, very little about shifts in metabolome pine trees affected by decline. The aim our work was unravel whether bacterial fungal communities inhabiting rhizosphere root endosphere P. with symptoms Matsucoccus feytaudi National Park Sierra Nevada (Granada, Spain) showed alterations structure, taxonomical profiles associative patterns. We also aimed at deciphering potential changes metabolome.

Bio-inspired core-shell microcapsules enhance storage stability and soil survival of non-spore bacteria for improving plant salinity tolerance

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: March 27, 2025

Non-spore-forming bacteria exhibit remarkable species diversity and sophisticated salt-resistance mechanisms, making them predominant candidates for commercial microbial inoculants worldwide. However, their low viability during storage field application has severely constrained utilization. Inspired by the robust structure of spore dormancy, we propose a novel core-shell microcapsule (APC). Using Pantoea alhagi NX-11 as model, APC encapsulation improved from 2.95 to 8.43 log CFU/g after 12-week at room temperature. The survival mechanism is attributed APC-induced metabolic dormancy via suppression TCA cycle oxidative phosphorylation pathways. Notably, compared non-encapsulated NX-11, inoculation APC-encapsulated increased rice root dry weight 24.61% under salt stress in greenhouse experiments altered rhizosphere bacterial community structure. showed higher relative abundance rhizospheres treated with NX-11. Universality was validated two additional non-spore strains. These results demonstrate APC’s efficacy preserving enhancing plant tolerance, highlighting approach formulation development.

Meta-omics integration approach reveals the effect of soil native microbiome diversity in the performance of inoculant Azospirillum brasilense

Frontiers in Plant Science, Journal Year: 2023, Volume and Issue: 14

Published: June 29, 2023

Plant growth promoting bacteria (PGPB) have been used as integrative inputs to minimize the use of chemical fertilizers. However, a holistic comprehension about PGPB-plant-microbiome interactions is still incipient. Furthermore, interaction among PGPB and holobiont (host-microbiome association) represent new frontier plant breeding programs. We aimed characterize maize bulk soil rhizosphere microbiomes in irradiated (IS) native (NS) microbial community gradient (dilution-to-extinction) with Azospirillum brasilense Ab-V5, commercial inoculant. Our hypothesis was that promotion efficiency result niche occupation persistence according conditions. The effects Ab-V5 NS communities were evaluated microcosms by combined approach microbiomics (species-specific qPCR, 16S rRNA metataxonomics metagenomics) phenomics (conventional high-throughput methods). results revealed weak effect inoculation undiluted NS, contrasting positive dilutions 10-3, 10-6, 10-9 IS Ab-V5. Alpha diversity + samples higher than all other treatments time course 25 days after sowing (DAS). At 15 DAS, alpha indexes different between IS, but similar rhizospheric samples. These differences not persistent at demonstrating stabilization process rhizobiomes.

Aconitum carmichaeli Debx . is a traditional Chinese medicine that cultivated in China and Japan. However, the monoculturing of this herb substantially decreases soil quality. Therefore, scientific planting management crucial for resolving current problems cultivation A. In study, we conducted comparative study on environmental characteristics, growth quality intercropping with five local crops two different areas. Herb quality, including biomass secondary metabolites, rhizosphere characteristics were measured. The results showed improved polysaccharide content, decreased disease index, altered three monoester diterpenoid alkaloids diester accumulations. intercrops also increased pH, nitrogen-cycling-gene abundances, potentially beneficial microorganism it changed nutrient levels.
