The authors make two final comments. One is that in retrospect perhaps the differences in the biosynthesis of crinine and mesembrine alkaloids are not entirely unexpected in view of the widely different phylogenetic origins of the... 

Both electron transfer chains cannot substitute each other in reconstituted systems, which points to a different phylogenetic origin of mitochondrial and bacterial monooxygenases on the one hand and the microsomal enzymes on the other. Microsomes also contain cytochrome bs which is able to donate electrons to the monooxygenases. However, the physiological role of this cytochrome is still controversial and more than one function has to be considered. 

The urodaeal gland, which currently has no other known function, may have developed in this fashion, but even its phylogenetic origin is uncertain.
