Data from: Independent evolution of ancestral and novel defenses in a genus of toxic plants (Erysimum, Brassicaceae)
<p>Phytochemical diversity is thought to result from coevolutionary cycles as specialization in herbivores imposes diversifying selection on plant chemical defenses. Plants in the speciose genus <i>Erysimum</i> (Brassicaceae) produce both ancestral glucosinolates and evolutionarily novel cardenolides as defenses. Here we test macroevolutionary hypotheses on co-expression, co-regulation, and diversification of these potentially redundant defenses across this genus. We sequenced and assembled the genome of <i>E. cheiranthoides</i> and foliar transcriptomes of 47 additional <i>Erysimum</i> species to construct a phylogeny from 9,869 orthologous genes, revealing several geographic clades but also high levels of gene discordance. Concentrations, inducibility, and diversity of the two defenses varied independently among species, with no evidence for trade-offs. Closely related, geographically co-occurring species shared similar cardenolide traits, but not glucosinolate traits, likely as a result of specific selective pressures acting on each defense. Ancestral and novel chemical defenses in <i>Erysimum</i> thus appear to provide complementary rather than redundant functions.</p>

FIGURE 4. Majority rule consensus tree obtained from a Bayesian analysis of 27 perennial species based on ITS nrDNA sequences showing the phylogenetic position of Erysimum nemrutdagense. Malcolmia orsiana (DQ357560) and Malcolmia maritima (AM905723) were used as outgroup. Specimens of the new species are shaded in the clade. Posterior probabilities (PP) are given above branches. Thickened branches indicate significant Bayesian posterior probability ≥50. Figure of perennial life forms are according to Feliner (1992) [a: monocarpic perennial, b: polycarpic with axillary flowering shoots, c and d: polycarpic with flowering shoots arising from the rootstock, e: suffruticose].
