Metabolic niches in the rhizosphere microbiome: dependence on soil horizons, root traits and climate variables in forest ecosystems

Frontiers in Plant Science, Год журнала: 2024, Номер 15

Understanding belowground plant-microbial interactions is important for biodiversity maintenance, community assembly and ecosystem functioning of forest ecosystems. Consequently, a large number studies were conducted on root microbial interactions, especially in the context precipitation temperature gradients under global climate change scenarios. Forests ecosystems have high plants associated microbes, contribute to major primary productivity terrestrial However, impact metabolites/exudates traits soil functional groups along these poorly described The plant system exhibits differentiated exudation profiles considerable trait plasticity terms morphological/phenotypic traits, which can cause shifts abundance diversity. metabolites composed secondary volatile organic compounds that diverse roles appealing preventing distinct strains, thus benefit fitness growth, tolerance abiotic stresses such as drought. Climatic factors significantly alter quantity quality trees secrete into soil.

Root and Leaf Traits of Alfalfa Exhibit Distinct Responses to Soil Microbial Communities and Environmental Stresses

Journal of Sustainable Agriculture and Environment, Год журнала: 2025, Номер 4(1)

Опубликована: Фев. 5, 2025

ABSTRACT Ongoing climate change is negatively impacting crop productivity globally. Past research has highlighted that a diverse soil microbial community and variation in plant traits for resource acquisition can mitigate the negative impacts of factors on productivity. This study investigates effects two major environmental stressors—drought salinity stress, productivity, biomass allocation, root leaf trait responses under distinct diversities. Our results showed stress had stronger than drought stress. Shoot decreased by 30% 32.5% respectively, whereas 32% only Soil diversity did not affect Next, were mainly impacted both stresses diversity. Specific length specific area drought, tissue density was minimal Root affected communities. In contrast, nitrogen content increased, pheophytin (a breakdown product chlorophyll) when plants grown communities stresses, especially drought. These highlight importance response to stresses. We influences aboveground belowground traits, indicating need better management practices conserve promote

Balance between carbon gain and loss in warmer environments: impacts on photosynthesis and leaf respiration in four temperate tree species

Abstract The temperature sensitivities of photosynthesis and respiration remain a key uncertainty in predicting how forests will respond to climate warming. We grew seedlings four temperate tree species, including Betula platyphylla, Fraxinus mandshurica, Juglans mandshurica Tilia amurensis, at three regimes (ambient, +2 °C, +4 °C daytime air temperature). investigated net (Anet25), maximum rate RuBP-carboxylation (Vcmax25) RuBP-regeneration (Jmax25), stomatal conductance (gs25), mesophyll (gm25), leaf (Rleaf) dark (Rdark25) light (Rlight25) 25 all species. Additionally, we examined the Anet, Vcmax, Jmax, Rdark Rlight F. mandshurica. Our findings showed that warming-induced decreases Anet25, Vcmax25 Jmax25 were more prevalent late-successional species T. amurensis. Warming had negative impacts on gs25 Overall, Anet25 was positively correlated with across growth temperatures. However, positive correlation between observed only under warming conditions, negatively associated vapor pressure deficit. This implies deficit-induced decrease responsible for decline higher optimum Anet increased by 0.59 per 1.0 rise temperature. While elevated thermal optima it did not affect other sensitivity parameters Vcmax Jmax. Rdark25 affected any Rlight25 stimulated response curves altered warming, implying lack acclimation. ratios amurensis These results suggest Rleaf acclimate synchronously these
