Transcriptome analysis during root nodule symbiosis in Lotus japonicus.
To obtain gene expression profile during root nodule symbiosis in a Lotus japonicus n nin mutant (nin_CR), we conducted RNA-seq analysis using whole roots of Lotus japonicus MG20 WT plants,  the nin_CR mutants, and the nin-9 mutants at 0, 7, and 21 days after rhizobia inoculation.
