Expanding the regulon of the Bradyrhizobium diazoefficiens NnrR transcription factor: New insights into denitrification pathway

Genome-wide transcription profiling of B. diazoefficiens (formerly B. japonicum) wild type and nnrR mutant strain which were grown in free-living anoxic denitrifying conditions (using nitrate as final electron aceptor). This study includes also the expression data of the wild type strain grown oxically (samples GSM210269 to GSM210283 in GEO record number GSE8478). Keywords: CRP/FNR proteins, in vitro transcription, microoxia, nitrogen oxides, Rhizobia, transcriptomics Comparative transcriptional profiling of nnrR mutant cells with wild-type cells cultured anoxically with nitrate

本数据集针对大豆慢生根瘤菌（B. diazoefficiens，曾用名B. japonicum）的野生型菌株与nnrR突变菌株展开分析，样本培养条件为自由生活厌氧反硝化环境（以硝酸盐作为最终电子受体），涵盖全基因组转录谱数据。本研究同时包含该野生型菌株在有氧条件下培养的表达数据，对应GEO数据库编号GSE8478中的样本GSM210269至GSM210283。本研究核心为硝酸盐厌氧培养条件下nnrR突变细胞与野生型细胞的比较转录组分析。关键词：CRP/FNR蛋白、体外转录、微氧、氮氧化物、根瘤菌、转录组学。
