+The interesting with the tree produced (especially from DOGMA) is
+that organisms resulting from the first endosymbiosis are distributed in
+every of the lineage found in the chloroplast genome structure
+evolution: with Red Algae chloroplasts together in one lineage, and
+Green Algae and Land Plants chloroplasts together in antoher lineage;
+while oranisms resulting from secondary endosymbioses are localized in
+the tree: both the chloroplasts of Brown Algae and Dinoflagellates
+representatives are found exclusively in the lineage also comprising the
+Red Algae chloroplasts from which they evolved, while the Euglens
+chloroplasts are related to the Green Algae chloroplasts from which they
+evolved. This make sense in term of biology and history of lineages and
+theories of chloroplasts (and so photosynthetic ability) origins in
+different Eucaryotic lineages.
+Interestingly, The sole organisms included that possesses a
+chloroplast (and so a chloroplastic genome) but that have lost the
+photosynthetic ability (being parasitic plant) are found at the base of
+the tree, and not together with its related species phylogenetically,
+meaning that functional chloroplast genes are evolutionnary constrained
+when used in photosynthetic process, but loose rapidly their efficiency
+when not used. They are Cuscuta-grovonii an Angiosperm (flowering plant)
+at the base of the DOGMA Angiosperm-Conifers branch, and
+Epipactis-virginiana also an Angiosperm at the complete base of the tree.
+Another interesting result in your work is that Land Plants that
+represent single sublineage originating from the large and diverse
+lineage of Green Algae in Eucaryots history are present in two different
+branches of the DOGMA tree, associated with Green Algae, one branch
+comprising the "inferior" Land Plants (mosses and ferns) and the second
+comprising the "superior" Land Plants (Conifers and flowering plants).
+But independently of their split in two distinct branches of the DOGMA
+tree, the Land Plants always show a higher number of functional genes in
+their chloroplasts than their related Green Algae, probably meaning that
+terrestrial way of life necessitates more functional genes for an
+optimal photosynthesis than marine way of life. But a more detailed
+analysis of selected genes is necessary to better understad the reasons why.
