However, the PHS1 homoeolog group also showed no transcriptional compensation - PHS1-B1 transcripts were not increased in the phs1-a1 mutant and vice versa
This suggests that transcriptional compensation between homoeologs is not required for functional redundancy in wheat
6/8

Overall, we identified only very low levels of potential transcriptional compensation between homoeologs - generally, the non-mutated homoeologs did not change in expression relative to the WT

To answer this question, we performed RNA-seq on hexaploid EMS-mutagenised lines and identified homoeolog groups in which one homoeolog is affected by a premature termination codon (PTC) mutation
For these groups, we compared the homoeolog expression levels between the mutagenised line and WT
