Abstract

Nitrogen deficiency affects soybean growth and physiology, such as symbiosis with rhizobia; however, its effects on the bacterial composition of the soybean root microbiota remain unclear. A bacterial community analysis by 16S rRNA gene amplicon sequencing showed nitrogen deficiency-induced bacterial community shifts in soybean roots with the marked enrichment of Methylobacteriaceae. The abundance of Methylobacteriaceae was low in the roots of field-grown soybean without symptoms of nitrogen deficiency. Although Methylobacteriaceae isolated from soybean roots under nitrogen deficiency did not promote growth or nodulation when inoculated into soybean roots, these results indicate that the enrichment of Methylobacteriaceae in soybean roots is triggered by nitrogen-deficiency stress.
