Fig. 2 in Alkaloid chemophenetics and transcriptomics of the Nicotiana genus

Fig. 2. Euclidean-based hierarchical clustering of Nicotiana genus species. Prior to clustering mean root alkaloid biosynthesis gene expression as well as leaves and roots percentage alkaloid composition were subjected to log2 transformation. There are 3 black boxes enclosing species clustered together: first from top, 6 species from the Suaveolentes section; second, 9 species from the Suaveolentes section; and third, 4 species from the Rusticae section and 1 from the Undulatae section. Gene IDs and their acronyms (present in Table S2) together with alkaloid names are placed on the figure top. Clustering revealed transparent species segregation which corresponded to their sectional classification. Clusters where ≥50% of section species grouped together are enclosed by fade yellow dashed line, specifically: Tomentosae section (4/5), Paniculatae section (2/4), Suaveolentes section (17/21), Noctiflorae section (3/3), Rusticae section (4/5) and Repandae section (2/3).Published as part of Kaminski, Kacper Piotr, Bovet, Lucien, Laparra, Helene, Lang, Gerhard, Palo, Damien De, Sierro, Nicolas, Goepfert, Simon & Ivanov, Nikolai V., 2020, Alkaloid chemophenetics and transcriptomics of the Nicotiana genus, pp. 1-11 in Phytochemistry (112424) 177 on page 7, DOI: 10.1016/j.phytochem.2020.112424, http://zenodo.org/record/829585
