We also felt that the two recent studies that put the model that attributed a functional role to FLMd into question (Lutz et al., 2015; Sureshkumar et al.,2016) did not yet convincingly proof that any regulatory role for FLMd could be completely rejected. We therefore included FLMd in the present study to test a putative regulatory role of FLMd with our new genetic materials and testing FLM expression in different environmental conditions. We had discussed internally and before submission of the original manuscript whether it was possible to reduce the data load by omitting FLMd data but came to the conclusion that this would weaken the significance of the data set. We have now reexamined this point and made the following changes to reduce the FLMd data load:
