Table 1 Changes in the transcript abundance of homoeologues induced by allotriploidization and WGD*

From: The abundance of homoeologue transcripts is disrupted by hybridization and is partially restored by genome doubling in synthetic hexaploid wheat

  1. *Values differ significantly (P < 0.05) following the application of the Benjamini-Hochberg multiple test correction. Based on the CS gene models, the triplet genes were used in the comparison of homoeologues between A-, B, and D-subgenomes. Only those that at least one of three homoeologues were expressed with FPKM >1 in parents (number of total) were analyzed
