摘要:
植物根际促生菌对促进作物生长及减排农田土壤N2O具有重要作用。利用具有良好的促生及减排农田土壤氧化亚氮特性的施氏假单胞菌(Pseudomonas stutzeri)NRCB010,通过试验分析其促生特性、反硝化能力及耐干旱胁迫性能,并采用三代Pacbio Sequl和二代Illumina Novaseq平台进行全基因组测序。NRCB010具有较强的硝酸盐还原能力,对于无机难溶磷酸钙和磷酸锌具有较好的利用效果,产生铁载体,耐受6%的盐浓度,在10%~20%的PEG6000浓度下较好生长;其基因组大小为4 570 338 bp,编码4 182个基因;含有反硝化代谢的相关基因及铁载体、细菌素等次级代谢产物的基因簇,并含有阳离子抗菌肽(CAMP)在内的多种环境适应相关基因。本研究初步揭示了NRCB010促进作物生长、减排农田土壤N2O及其适应复杂环境能力的遗传学基础。
