Table 1 Pectinolytic genes that were significantly down-regulated in the A. niger ΔlraA, ΔlraB, ΔlraC and ΔrhaR strains compared to the reference in L-rhamnose

From: In vivo functional analysis of L-rhamnose metabolic pathway in Aspergillus niger: a tool to identify the potential inducer of RhaR

  1. Based on Gruben, B.S., M. Zhou, A. Wiebenga, J. Ballering, K.M. Overkamp, P.J. Punt & R.P. de Vries, (2014) Aspergillus niger RhaR, a regulator involved in L-rhamnose release and catabolism. Appl Microbiol Biotechnol 98: 5531-5540
  2. The expression levels are mean values of duplicate samples. Genes with values higher than 120 are considered highly expressed and marked red.
  3. Genes with values lower than 20 are considered low expressed and marked green.
  4. The fold change is the difference in expression between the reference strain and the deletion mutants.
  5. The cutoff for differential expression is fold change >1.5 (cells marked red if upregulated and green if downregulated) and p-value <0.05 (cells marked yellow).
  6. HGA homogalacturonan, RG-I Rhamnogalacturonan-I, SC side chains, PAE = pectin acetyl esterase, RGX = exorhamnogalacturonase
  7. RHA = endorhamnogalacturonase, URH = unsaturated rhamnogalacturonyl hydrolase, RGL = rhamnogalacturonan lyase
  8. RGAE = rhamnogalacturonan acetyl esterase, LAC = beta-galactosidase, FAE = feruloyl esterase.
