Different expression levels based on fold change (FC, signal from B deficient roots/signal from B sufficient roots; “-” means the value of the signal from B sufficient roots/signal from B deficient roots) is indicated. Significant difference (FDR < 0.01 and fold change ≥ 2) in relative level are shown in bold.
