**Appendix D**

The nomenclature in the cotton literature is somewhat confusing. Some FLAs are named AGPs and GhFla1 refers to two entirely different protein sequences. The GhFla1 that was mentioned by Li et al. (2010) [160] being most similar to *AtFla9/6/13* and the *GhFla1* silenced by Huang et al. (2013) [159] is an ortholog of *AtFla11/12*. The *GhAgp4* locus (gb EF470295) silenced by Li (2010) [160] is identical to the sequence annotated as *GhFla12*.
