Neighbour-induced changes in root exudation patterns of buckwheat results in altered root architecture of redroot pigweed

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: April 15, 2024

Abstract Roots are crucial in plant adaptation through the exudation of various compounds which influenced and modified by environmental factors. Buckwheat root exudate system response to neighbouring plants (buckwheat or redroot pigweed) how these exudates affect pigweed was investigated. Characterising plant–plant interactions presents challenges, therefore a split-root enabled application differential treatments parts single non-destructive sampling developed. Non-targeted metabolome profiling revealed that neighbour presence identity induces systemic changes. upregulated 64 46 metabolites, respectively, with an overlap only 7 metabolites. Root morphology analysis showed that, while decreased number tips buckwheat, buckwheat total length volume, surface area, tips, forks pigweed.

Nitrogen-Fixing Plants Enhance Soil Phosphorus Availability by Promoting Transformations Among Phosphorus Fractions in a Subtropical Karst Forest

Forests, Journal Year: 2025, Volume and Issue: 16(2), P. 360 - 360

Published: Feb. 17, 2025

Nitrogen (N)-fixing plants are commonly employed in the restoration of degraded terrestrial ecosystems due to their ability increase soil N capital and boost ecosystem productivity. Given close coupling between phosphorus (P) soil, effects N-fixing on P fractions availability karst forests remain largely unexplored. Herein, we compared pools, fractions, rhizosphere non-rhizosphere soils non-N-fixing plants, explored associated drivers, such as microbial, plant properties, a subtropical forest. The results showed that increased total P, inorganic available both soils. nitrogen-fixing labile (LP) non-labile (NLP), but decreased moderately (MLP), particularly soils, transformations among different fractions. Soil were primarily influenced by root leaf N, microbial biomass treatment, whereas dissolved organic carbon (DOC), (DON) key factors treatment. Consequently, attributes, nutrients, collectively exerted direct indirect In contrast, directly properties indirectly Our revealed unique role driving forests. These findings essential for developing effective strategies nutrient management guiding selection appropriate species vegetation regions.

Eco‐Evolutionary Dynamics of Plant–Soil Feedbacks Explain the Spread Potential of a Plant Invader Under Climate Warming and Biocontrol Herbivory

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(3)

Published: March 1, 2025

Plant-soil feedbacks (PSFs) can contribute to the success of invasive plants. Despite strong evidence that plant genetic traits influence soil microbial communities and vice versa, empirical exploring these over evolutionary timescales, especially under climate change, remains limited. We conducted a 5-year field study annual plant, Ambrosia artemisiifolia L., examine how selection warming biocontrol insect herbivory shapes population genetics, properties, communities. After four generations herbivory, we collected seeds F4 populations together with their conditioned for common garden PSF experiment explore resulting PSFs patterns are influencing performance spread potential changing environmental conditions.

Root Endophyte-Manipulated Alteration in Rhizodeposits Stimulates Claroideoglomus in the Rhizosphere to Enhance Drought Resistance in Peanut

Journal of Agricultural and Food Chemistry, Journal Year: 2024, Volume and Issue: 72(36), P. 20211 - 20223

Published: Aug. 28, 2024

Drought dramatically affects plant growth and yield. A previous study indicated that endophytic fungus Phomopsis liquidambaris can improve the drought resistance of peanuts, which is related with root arbuscular mycorrhizal fungi (AMF) community; however, how endophytes mediate AMF assembly to affect remains unclear. Here, we explored mechanism by recruits symbiotic partners via rhizodeposits host resistance. The results showed Ph. enhanced peanut enriching genus Claroideoglomus rhizosphere. Furthermore, metabolomic analysis significantly promoted isoformononetin salicylic acid (SA) synthesis in rhizodeposits, were correlated increase abundance following inoculation. Coinoculation experiments confirmed SA could enrich etunicatum rhizosphere, thereby improving This highlights crucial role fungal consortia stress

Summary Microbiota have co‐evolved with plants over millions of years and are intimately linked to plants, ranging from symbiosis pathogenesis. However, our understanding the existence a shared core microbiota across phylogenetically diverse remains limited. A common garden field experiment was conducted investigate rhizosphere microbial communities contrasting herbaceous families. Through combination metagenomic sequencing, analysis plant economic traits, soil biochemical properties, we aimed elucidate eco‐evolutionary role in light strategies. We identified conserved consisting 278 taxa that closely associated phylogeny studied. This actively participated multiple nitrogen metabolic processes showed strong correlation functional potential cycling, thereby serving as an extended trait acquisition. Furthermore, examination simulated species loss revealed crucial maintaining community's network stability. Our study highlighted microbiota, which exhibited association potentially represented extension phenotype played important These findings held implications for utilization microbiota‐mediated functions.
