Of fourCharacter coding and reconstruction of ancestral statesIn order to infer the evolutionary history of traits related to niche use and defense inside Tenthredinidae, we collected information on diet program breadths, host-plant associations, and host attributes, at the same time as on larval ecology, behavior, morphology, and chemically-based defensive methods within the species incorporated within the phylogenetic trees. We then coded the information as unordered binary or multistate characters, and reconstructed ancestral states by singlerate (Mk1) maximum likelihood (ML) optimization in Mesquite v. 2.75 [63]. Grey shaded bars show 95 highest posterior density intervals for relative node ages for nodes with posterior probabilities more than 50 .deleted from the matrix and linked trees before each and every reconstruction. Host plants have been compiled from literature sources [55,64] and every single sawfly was coded for its diet plan breadth (Figure three). In the case of species for which dependable hostplant records were missing, diet program breadth was coded as unknown, unless revealed by additional laboratory testing with larvae in the exact same population.To evaluate the toxicity of plants on which sawflies feed, every plant genus (and species, as far as you possibly can) was connected with all the occurrence of toxins, by referring to standard functions around the chemistry of plants [65-70] and to smaller andor far more recent functions (e.g., [45]). A plant taxon was thought of toxic if the leaves contain secondary metabolites from one or more with the following chemical classes: alkaloids (which includes steroid alkaloids and steroidBoevet al.

The BEAST MCC tree is based on evaluation of Dataset two, which consists of all NSC600157 chemical information sequenced tenthredinids at the same time as representatives from 3 non-blasticotomid families in Tenthredinoidea. Posterior probabilities ( ) resulting from analyses in BEAST and MrBayes are offered above and under branches, respectively (clades not present in the MrBayes tree are indicated by hyphens). Grey shaded bars show the 95 highest posterior density intervals for relative node ages for nodes with posterior probabilities exceeding 50 . Branch colors denote host plant classes of your sawfly species (see legend) and ancestral reconstructions depending on maximum-likelihood optimization across 1,000 post-burnin trees (see Additional file 4A).

All these compounds, except steroid saponins, have in common the inclusion of one particular or much more nitrogen atoms. Nitrogencontaining secondary metabolites show acute toxicity andor strong feeding deterrence towards vertebrates andor invertebrates, and they may be the most widespread defensive chemical substances of plants [65,68-70,72]. A plant taxon was deemed non-toxic if it only consists of secondary metabolites that usually do not contain nitrogen, for example phenolics (e.g., coumarins, phenolic glycosides, and also the w.
