Carissa L., a genus of the family Apocynaceae with about 250 genera, consists of 36 species as evergreen shrubs or small trees native to tropical and subtropical regions of Africa, Asia and Oceania [1, 2].
These genera consist of 'ecotypes' that are specialized for ocean habitats that differ in irradiance, temperature, and nutrient availability.
It is important to note that genus level comparison may be too coarse to identify taxa that are associated with diseases since many of the above genera consist of pathogens and non-pathogens (e.g. Prevotella and Streptococcus have been found on both healthy and diseased oral tissues).
In contrast, Ruschioideae contains about 1585 species in 112 genera, with the early diverging group consisting of ten genera and 22 species, and the species-rich core group consisting of 1563 species in 102 genera (Klak et al., 2003b; Table 1).
Polytomies with branch length values of zero were constructed for genera that consisted of multiple focal taxa without cytB sequences.
It is a member of the mycolic acid containing group consisting of genera Corynebacterium, Dietzia, Gordonia, Mycobacterium, Nocardia, Rhodococcus, and Tsukamurella.
Musaceae, the banana family of plants (order Zingiberales), consisting of 2 genera, Musa and Ensete, with about 50 species native to Africa, Asia, and Australia.
Droseraceae, sundew plant family, consisting of three genera and some 155 species of carnivorous plants in the order Caryophyllales.
Agavoideae, the agave subfamily of the flowering plant family Asparagaceae (order Asparagales), consisting of 23 genera and 637 species of short-stemmed, often woody plants distributed throughout tropical, subtropical, and temperate areas of the world.
