Comparison of the gene expressions of 8 DEGs cultured with NH4+ (treatment) and Gln (control) as the sole nitrogen source determined by Illumina HiSeqâ„¢ 2500 sequencing and RT-qPCR using 16S rRNA gene as reference control. The x-axis displays 8 genes and y-axis is the expression levels (fold changes). Sensor histidine kinase (glnK), DNA-binding response regulator (glnL), MFS transporter (mnrA), Rrf2 family transcriptional regulator (ywnA), CarD family transcriptional regulator (ydeB), Nitrate reductase subunit gamma (narI), Threonine synthase (thrC), Homoserine kinase (thrB). The positive and minus value means up-regulated and down-regulated, respectively to three parallel experiments
