Table I. Detection of known NF-induced genes in this study and in recent transcriptomic analyses

Values correspond to the regulation levels (fold change) following NF treatment for the indicated times or S. meliloti inoculation at 5 d post inoculation (RH-5dpi; skl mutant background), determined in this study versus previous studies: a, Rose et al. (2012); b, van Zeijl et al. (2015); c, Czaja et al. (2012); and d, Breakspear et al. (2014). For entries in parentheses, differences were not statistically significant (adjusted P > 0.05). ART, All root tissues from whole root systems (a) or 1- to 2-cm-long root segments (b and c); NA, not applicable (no corresponding gene in the M. truncatula genome sequence used); NF, RNAseq reads were detected only in the NF-treated samples.
