The overall research program will quantify denitrification gene expression via reverse transcription- Real time PCR in Pseudomonas mandelli and indigenous soil microorganisms under diverse soil conditions including the rhizosphere. Global warming has been identified as a priority international threat to our common, shared, biosphere, resulting in immense social, environmental, agricultural, public health and economic consequences that cannot be easily estimated and forecasted. Nitrous oxide (N2O) is one of several greenhouse gases that contribute to global warming. Atmospheric concentrations of N2O have been increasing at an alarming rate of 0.2-0.3% per year since the preindustrial period.

整个研究计划将通过逆转录-真实的时间PCR定量反硝化基因的表达在不同的土壤条件下，包括根际假单胞菌和土著土壤微生物。全球变暖已被确定为对我们共同、共有的生物圈的一个优先国际威胁，造成了难以估计和预测的巨大社会、环境、农业、公共卫生和经济后果。一氧化二氮（N2 O）是导致全球变暖的几种温室气体之一。自前工业化时期以来，大气中N2 O的浓度一直以每年0.2-0.3%的惊人速度增长。
