Contrasting Soil Microbial Functional Potential for Phosphorus Cycling in Subtropical and Temperate Forests

چکیده
Microorganisms play important roles in phosphorus (P) cycling via their regulation of P uptake and transport, mineralization solubilization, the mediation deficiency forest biomes. However, dynamics microbial functional genes underlying regulatory mechanisms different biomes (e.g., temperate vs. subtropical) have yet to be sufficiently clarified. In this study, we applied a metagenomics approach investigate changes abundance three gene groups (P starvation response genes, transport solubilization genes) along subtropical–temperate gradient (23° N–45° N) China. Our results revealed that abundances were significantly higher than those subtropics (p < 0.05), although not cases other two types > 0.05). Moreover, both subtropical forests, Acidobacteria, Actinobacteria, Proteobacteria, Verrucomicrobia identified as key phyla associated with cycling; moreover, found dominate species Acidobacteria Proteobacteria at genus level zones zones, most cases. Furthermore, our showed significant correlation was between α-diversity latitude gradient. biomes, community positively correlated whereas related 0.001), forests addition, soil substrates negative relationships case forests. Collectively, these findings indicate responses environmental variation are more sensitive thereby providing theoretical foundation for further elucidation differential

Spatial Distribution of Soil Nitrogen, Phosphorus and Potassium Stocks in Moso Bamboo Forests in Subtropical China
Moso bamboo is famous for fast growth and biomass accumulation, as well as high annual output for timber and bamboo shoots. These high outputs require high nutrient inputs to maintain and improve stand productivity. Soil nitrogen (N), phosphorus (P) and potassium (K) are important macronutrients for plant growth and productivity. Due to high variability of soils, analysing spatial patterns of s...
متن کاملSoil phosphorus functional fractions and tree tissue nutrient concentrations influenced by stand density in subtropical Chinese fir plantation forests
Stand density regulation is an important measure of plantation forest management, and phosphorus (P) is often the limiting factor of tree productivity, especially in the subtropics and tropics. However, the stand density influence on ecosystem P cycling is unclear in Chinese fir (Cunninghamia lanceolata) plantations of subtropical China. We collected rhizosphere and bulk soils, leaves and twigs...
متن کاملVariations of Soil Microbial Community Structures Beneath Broadleaved Forest Trees in Temperate and Subtropical Climate Zones
Global warming has shifted climate zones poleward or upward. However, understanding the responses and mechanism of microbial community structure and functions relevant to natural climate zone succession is challenged by the high complexity of microbial communities. Here, we examined soil microbial community in three broadleaved forests located in the Wulu Mountain (WLM, temperate climate), Funi...
متن کاملMicrobial Activity and Phosphorus Availability in A Subtropical Soil under Different Land Uses
Land use changes in the Everglades Agricultural Area (EAA) of south Florida may alter microbial activity and organic matter decomposition and ultimately influence the fate of P in soil. The objectives of this study were to determine effects of long-term cultivation and fertilization on microbial activity and P dynamics for contrasting land uses in the EAA. Soils (0-15 cm) under pasture for 100 ...
