Male, female, and mixed‐sex poplar plantations support divergent soil microbial communities

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(2)

Published: Feb. 1, 2024

Males and females of dioecious plants have sex-specific adaptations to diverse habitats. The effects inter- intrasexual interactions in poplar plantations on composition, structure, function soil microbiota not been explored degraded areas. We conducted a series greenhouse field experiments investigate how belowground competition, microbial communities, seasonal variation nitrogen content differ among female, male, mixed-sex Populus cathayana plantations. In the experiment, female neighbors suppressed growth males under optimal conditions. However, male enhanced stable isotope ratio (δ

The assembly process and co-occurrence network of soil microbial community driven by cadmium in volcanic ecosystem

Resources Environment and Sustainability, Journal Year: 2024, Volume and Issue: 17, P. 100164 - 100164

Heavy metal (HM) contamination affects the composition and structure of soil microbial communities, but there are few studies on assembly process co-occurrence network community succession driven by Cd in volcanic ecosystem. To address this gap knowledge, we collected analyzed samples from Nvshan Volcanic area to understand characteristics primary (PS) secondary (SS). We found that was contaminated with different levels (PS > SS), resulting obvious heterogeneity microorganisms. The absolute abundance bacteria (16S rRNA gene copies) varied significantly between two successions (P < 0.0001). networks analysis showed number nodes bacterial communities lower PS compared SS (1002 vs. 1004), indicating heavy would reduce communities. Compared PS, exhibited stronger competitiveness (positive: negative, P/N: 25.69 64.22), whereas fungal were closer symbiotic relationships (positive/negative, 15.85 14.29). neutral model (NCM) revealed stochastic processes predominantly governed (bacterial R2: 0.657, 0.686).

Microbial Biotic Associations Dominated Adaptability Differences of Dioecious Poplar Under Salt Stress

Plant Cell & Environment, Journal Year: 2025, Volume and Issue: unknown

How different stress responses by male and female plants are influenced interactions with rhizosphere microbes remains unclear. In this study, we employed poplar as a dioecious model plant quantified biotic associations between microorganisms to explore the relationship microbial adaptation. We propose health index (HI) comprehensively characterize physiological characteristics adaptive capacity of under stress. It was found that poplars demonstrated higher salt tolerance than females, root-secreted citric acid significantly in rhizospheres poplars. Positive association among bacteria increased HI stress, while fungal cross-domain (bacteria-fungi) did not. further identified keystone bacterial taxon regulating association, ASV_22706, which itself regulated positively correlated host HI.

Expression of Secondary Sexual Dimorphism in the Diurnal Course of Leaf Gas Exchanges Is Modified by the Rhythmic Growth of Ilex paraguariensis Under Monoculture and Agroforestry

Forests, Journal Year: 2025, Volume and Issue: 16(1), P. 161 - 161

Published: Jan. 16, 2025

Dioecious species show a division of labor expressed through the differentiated manifestation resource acquisition. We hypothesized that expression secondary sexual dimorphism (SSD) in leaf gas exchange yerba mate would be more intensive females than males to permit carbon investments necessary finish reproductive cycle. This can present two growth units annually (GU1-fall and GU2-spring) intercalated with rest periods (R1-summer R2-winter). The area index (LAI) diurnal courses photosynthesis (Anet), stomatal conductance (gs), transpiration (E), intercellular CO2 concentration (Ci), water use efficiency (WUE), instantaneous carboxylation (Anet/Ci) were estimated female male plants during four annual rhythmic monoculture (MO) agroforestry (AFS). Leaf exchanges varied over under MO AFS. Anet, Anet/Ci ratios, WUE higher summer (R1) spring (GU2). Also, gs E summer. Oppositely, was observed fall (GU1) winter (R2), also showing ratio Despite strong effect cultivation system on LAI traits course, SSD rarely modified by system, being only for (GU2) (R2). High benefit cold dry periods, improving balance between acquisition loss transpiration. On other hand, high Anet could considered as general fitness strategy improve photoassimilate supply support their additional reproduction costs.

China is a largely agricultural country, while the drought climate in northern of more and severe, which influences on agriculture production seriously. The over-exploitation groundwater critical issue low plains Hebei Province. To address this challenge, government has implemented winter fallow rain-fed crop planting policies. In alignment with these policies ensure sustainable utilization protection cultivated land, study conducted long-term field experiments using three green manure foxtail millet rotation models at Shenzhou District experimental base, Hengshui City, Thefoxtail yield, soil bacterial community characteristicsc, physicochemical properties were analyzed to identify an optimal model for promoting development. results revealed that manure-foxtail significantly increased yield compared millet-rallow rotation. millet–Triticum secale achieved highest increase, 12.47% average improvement thousand-seed weight 2021 2022 millet-fallow This also led largest increase available phosphorus content, rose by 46.16 37.56% 2022, respectively.
