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).
Fig. 1 in Alkaloid chemophenetics and transcriptomics of the Nicotiana genus
Fig. 1. Current state-of-the-art picture of alkaloid biosynthesis in Nicotiana genus. Gene acronyms are provided in red next to the enzymatic steps they correspond to. Each gene acronym is explained in boxes with full gene names. Compound full names are provided in black, with additional 2D structure representation of alkaloids: anabasine, nicotine, nornicotine, anatabine, cotinine, myosmine as well as nicotinic acid. Additional 2D structures are also presented for alkaloids intermediates: Δ1-piperdiene, N-methyl-Δ1-pyrrolinium cation, 3,6-dihydronicotinic acid, and 2,5-dihydropyridine. In faded green, field steps of polyamine biosynthesis are presented, whereas the faded red field encloses steps limited to plastid and root tissue. Question marks are located next to enzymatic steps that are currently only hypothesized and have not yet been confirmed by independent studies. The figure is based on a review by Dewey and Xie (2013) and subsequent studies, that characterized the functions of further genes, namely LDC (Bunsupa et al., 2014) and NUP1 (Kato et al., 2015), in the alkaloid biosynthetic pathway.
Fig. 3 in Alkaloid chemophenetics and transcriptomics of the Nicotiana genus
Fig. 3. PCC matrix between gene expressions mean RPKM values and mean alkaloid accumulation metabolite data. Genes are presented with their Gene ID and Identifiers (full description of genes with names in Fig. 1 & Table S2). Six gene-specific comparisons were performed to calculate Pearson correlation coefficient, as presented in the table: leaf nornicotine to nicotine content ratio vs. leaf gene expression; total nicotine content (leaf and root) vs. root gene expression; total anatabine content (leaf and root) vs. root gene expression; root anatabine to nicotine and nornicotine content ratio vs. root gene expression; total anabasine content (leaf and root) vs. root gene expression; total alkaloid content leaf to root ratio vs. root gene expression. PCC values range from −1 to 1, with red white conditioning in negative to positive correlation. PCC values in bold and marked with thick borders represent correlations of significant importance.

Nicotiana benthamiana as a transient expression host to produce auxin analogues: Pisum sativum seed transcriptomic data
<p>Plant secondary metabolites have applications for the food, biofuel, and pharmaceutical industries. Recent advances in pathway elucidation and host expression systems now allow metabolic engineering of plant metabolic pathways to produce "new-to-nature" derivatives with novel biological activities, thereby amplifying the range of industrial uses for plant metabolites. Here we use a transient expression system in the model plant <i>Nicotiana benthamiana</i> to reconstitute the two-step plant-derived biosynthetic pathway for auxin (indole acetic acid) to achieve accumulation up to 500 ng/g fresh mass (FM). By expressing these plant-derived enzymes in combination with either bacterial halogenases and alternative substrates, we can produce both natural and new-to-nature halogenated auxin derivatives up to 990 ng/g FM. Proteins from the auxin synthesis pathway, tryptophan aminotransferases (TARs) and flavin-dependent monooxygenases (YUCs), could be transiently expressed in combination with four separate bacterial halogenases to generate halogenated auxin derivatives. Brominated auxin derivatives could also be observed after infiltration of the transfected <i>N. benthamiana</i> with<i> </i>potassium bromide and the halogenases. Finally, the production of additional auxin derivatives could also be achieved by co-infiltration of TAR and YUC genes with various tryptophan analogues. Given the emerging importance of transient expression in <i>N. benthamiana</i> for industrial scale protein and product expression, this work provides insight into the capacity of <i>N. benthamiana</i> to interface bacterial genes and synthetic substrates to produce novel halogenated metabolites.</p>
