The assembly of the rhizosphere community, even diazotroph is mainly shaped by soil environmental factors (including climate and physiochemical characteristics) plant selection. To better understand driving forces on active overall nitrogen-fixing bacterial community compositions, we characterized communities tobacco collected from three sampling sites with a large geographic scale (> 600 km). results indicate that diversity composition are obviously differed according to sites. Still, no significant difference found between in rootzone samples. Climate variables including mean annual precipitation (MAP) temperature (MAT), characteristics available nitrogen (AN), potassium (AK) pH main affect structures Furthermore, MAP MAT, AN phosphorus (AP), total (TN) organic carbon (OC), AK electrical conductivity (EC) showed similar effects, but independent effect bacteria communities. However, alpha indices higher than samples, differences observed among different Proteobacteria predominant phylum all samples for bacteria.

These contribute more assemblage, contributes community. Our study provides novel knowledge assemble across geographical scale.

Identification of Peanut Cultivars with Low Cadmium Contents and Their Rhizosphere Microbial Characteristics in Alkaline and Acidic Cadmium-Contaminated Fields

Sustainability, Год журнала: 2025, Номер 17(2), С. 626 - 626

Опубликована: Янв. 15, 2025

Employing crop cultivars with low cadmium (Cd) accumulation and high yield is an effective strategy for the sustainable safe utilization of Cd-contaminated farmland. However, current understanding peanut cultivars, particularly under field conditions, limited. This study identified low-Cd their rhizosphere microbial characteristics in acidic alkaline fields moderate Cd contamination. The results indicated that LH11, FH1, LH14, YH9414 exhibited yield, kernel content reduced by 27.27% to 47.28% increased 9.27% 14.17% compared cultivar SLH. Among them, FH1 was validated achieve production two fields. A unique community formed recruitment diverse microbes, such as Alphaproteobacteria, Acidobacteria, Gemmatimonadetes, Chloroflexi, soil which might be associated immobilization promotion plant growth. Functional predictions further these findings, revealing enhanced functional pathways related proliferation, stabilization, detoxification. provides valuable germplasm resources agriculture Cd-polluted soils elucidates different conditions. These findings are important targeted management contaminated farmland ensuring food production.

Transgenic Maize of ZmMYB3R Shapes Microbiome on Adaxial and Abaxial Surface of Leaves to Promote Disease Resistance

Microorganisms, Год журнала: 2025, Номер 13(2), С. 362 - 362

Опубликована: Фев. 7, 2025

The phyllosphere is one of the largest habitats for microorganisms, and host genetic factors play an important role during interaction between microorganisms phyllosphere. Therefore, transgene may also lead to changes in maize ZmMYB3R was identified as a drought-tolerant gene Arabisopsis. Here, we employed metagenomic sequencing analyze microbiome adaxial abaxial leaf surfaces on ZmMYB3R-overexpressing (OE) wild-type (WT)·maize, aiming dissect possible associations functioning. Our results revealed that overexpressing altered alpha beta diversity microbiome. In OE plants, more beneficial microbes accumulated phyllosphere, while pathogenic ones diminished, especially surface leaves. Further analysis disease resistance-related metabolic pathways abundances resistance genes significant differences WT. inoculation experiment WT proved increased maize. conclusion, reveal transgenes affect microbiome, might alter by reshaping structure. These findings help us understand how regulates facilitate development control harnessing microbial communities.

ABSTRACT Wild plants growing in alpine regions are associated with endophytic microbial communities that may support plant growth and survival under cold conditions. The structure function of bacterial were characterized flowers, leaves, roots three Rosaceae Alpine areas using a combined amplicon sequencing culture-dependent approaches to determine the role core taxa on freezing stress tolerance. Amplicon analysis revealed tissue, collection site, host main factors affecting richness, diversity, taxonomic plants. Core identified as 31 sequence variants highly prevalent across all tissues. Psychrotolerant endophytes belonging Duganella , Erwinia Pseudomonas Rhizobium genera mitigated strawberry plants, demonstrating beneficial their potential use for mitigation agriculture. IMPORTANCE Freezing is one major abiotic stresses fruit production crops. Current strategies reduce damage include physical chemical methods, which have several limitations terms costs, efficacy, feasibility, environmental impacts. or manipulation plant-associated was proposed promising sustainable approach alleviate crops, but no information available possible A combination sequencing, culture-dependent, bioassay In particular, we showed culturable psychrotolerant can mitigate seedlings. Overall, this study demonstrates development biostimulants
