摘要:
温度是影响土壤中微生物介导的元素生物地球化学循环的重要因素。以广东省茂名市的稻田土壤为研究对象,利用高通量功能基因芯片对71种土壤元素循环相关的功能基因丰度进行测定并结合温度和培养时间等因子,研究了水稻土中微生物介导的碳、氮、磷、硫循环对温度的响应。结果表明:在检测的71种碳、氮、磷、硫相关基因中,63%的功能基因的丰度在35 ℃的培养温度中显著升高,并且这种趋势伴随培养时间的增加而显著增加。其中氮循环中的氨氧化过程中的amoA 基因对温度的响应最为明显,响应比分别为35 ℃/15 ℃的(12.79 ± 1.82)和35 ℃/25 ℃的(8.44 ± 1.79)。揭示了土壤碳氮磷硫循环关键功能基因丰度对温度的响应特征,也为温度变化引起土壤微生物元素化学循环变化趋势的理论研究提供了基础。

Abstract:
Temperature is an important factor influencing the microbially mediated nutrient cycles in soil. In this study, a paddy soil collected in Maoming City, Guangdong Province was selected as the research object. The effect of temperature on the abundance of 71 functional genes related to soil element cycling was determined using high-throughput functional gene chips. The results show that among the 71 detected carbon, nitrogen, phosphorus,and sulfur cycling related genes, the abundance of 63% of functional genes significantly increases at a cultivation temperature of 35 ℃, and this trend further increases with the prolongation of incubation time. Among them, the abundance of amoA gene involved in the nitrification process in the nitrogen cycle shows the most significant response to temperature, with response ratios of (12.79 ± 1.82) (35 ℃/15 ℃) and (8.44 ± 1.79) (35 ℃/25 ℃). The study reveals the response characteristics of key functional gene abundance in soil carbon, nitrogen, phosphorus, and sulfur cycles to temperature, providing a foundation for theoretical research on the trends of soil microbial element cycling caused by temperature variations.
