I'm reading a paper on genetic transformation of a fungi and the plasmid used in the paper uses two forms of the same GPD (glyceraldehyde3-phosphate dehydrogenase) promoter to drive a GFP gene, one from Agaricus bisporus and one from Lentinula edodes (GenBank: GQ457137.1).
However, I noticed that the sequences for the aforementioned GPD promoters do not match the reference sequence in GenBank (NC_007251.2) which itself is derived from another organism.
Why are there different sequences for the same promoter? Furthermore, how would I identify the GPD gene in another organism if I'm unable to compare it to a known sequence?
The organism I wish to transform has had it's complete genome sequenced and my transformation would be much more effective if I could use a native promoter like GPD.
