Fig. 3: Syntenic biosynthetic gene clusters containing 24ISO in withanolide-producing Solanaceae plants.

a Synteny plot. Gene lengths are unified for clarity. N. tabacum is included as an outgroup of the subfamily Solanoideae. W. somnifera 1 and W. somnifera 2 refer to the two gene clusters in W. somnifera on ctg090 and ctg003, respectively. The phylogenetic relationships shown at the left are adapted from ref. 131. b Heatmap summary of gene copy numbers of each gene family. Background colour is normalised to the highest number per column. Expression information about genes in the cluster are displayed in Supplementary Figs. 9–11.
