Genus Rhododendron
Example of a phylogenetic tree using ITS and matK variations.
ITS do not have important sequences. RPB2-I and ITS have more gaps and therefore difficult to work with. No gaps in matK coding area. RPB2-I sequence exon 23-24 gave a lot of “noise” using some programes, mostly from parts of exon 23 and 24 if exons is not cut out.
Kron 1996 used matk on 14 species Mensezia belongs to Genus Rhododendron.

Taxonomi
Mensezia belongs to Genus Rhododendron, R. vaseyi is close to R. albrechti and R. canadense to Pentantera Used 29 species om matk and ITS.
Kurashie Y, et al. 2001: Sectional relationships in the genus Rhododendron (Ericaceae): Evidence from matK and trnK intron sequences), Plant Systematics and Evolution 228 (1-2). Used 267 species
Goetsch et al. 2005 classification used mostly non-coding sequencies in RPB2-I. Exon areas is cut out before use (B. Hall 2007). Goetsch et al. data are very informative and the largest to day and the “noise” give only minor problems? At the moment the Menziesia group is in this Genus. R. camtchaticum is a matter of feelings.
Historisk udgave – klassifikationsoversigt 1996
My version 1/4-2007 Hans Eiberg – Mange har nu fået et gruppenavn (sec./subsec.) i Flora of China ** kommentarer. Flora of China’s klassifikation er delvist bygget på DNA analyser.
(Subgenus Menziesia (HE) (If Therorhodion is in this genus, then Menziesia is also (HE, 1997) – also after DNA studies of several DNA regions)
