Table 1 Overrepresented KEGG pathways in cotton fiber implicated by metabolites or enzyme-encoding transcripts. Entries reflect the combined data from Gh and Gb fiber

From: Metabolomic and transcriptomic insights into how cotton fiber transitions to secondary wall synthesis, represses lignification, and prolongs elongation

  1. Italics indicate overrepresented pathways implicated by both metabolites and transcripts. Overrepresentation of pathways (p < 0.02, q < 0.09) was determined by Fisher’s exact test followed by Benjamini-Hochberg correction of the p-values (see Additional files 4 and 7)
