“…A precondition for using DNA barcoding to identify species is that species are monophyletic (Hebert, Cywinska, et al., ). However, lots of studies have demonstrated that many species from Asteraceae are paraphyletic or polyphyletic (Godoy et al., ; Rieseberg & Brouillet, ), which is likely to be another reason for the low discrimination rates. In addition to these reasons, another possible factor could be improper taxonomic treatment or cryptic speciation (Zhang et al., ).…”

Invasive plants have aroused attention globally for causing ecological damage and having a negative impact on the economy and human health. However, it can be extremely challenging to rapidly and accurately identify invasive plants based on morphology because they are an assemblage of many different families and many plant materials lack sufficient diagnostic characteristics during border inspections. It is therefore urgent to evaluate candidate loci and build a reliable genetic library to prevent invasive plants from entering China. In this study, five common single markers (ITS, ITS2, matK, rbcL and trnH-psbA) were evaluated using 634 species (including 469 invasive plant species in China, 10 new records to China, 16 potentially invasive plant species around the world but not introduced into China yet and 139 plant species native to China) based on three different methods. Our results indicated that ITS2 displayed largest intra-and interspecific divergence (1.72% and 91.46%). Based on NJ tree method, ITS2, ITS, matK, rbcL and trnH-psbA provided 76.84%, 76.5%, 63.21%, 52.86% and 50.68% discrimination rates, respectively. The combination of ITS + matK performed best and provided 91.03% discriminatory power, followed by ITS2 + matK (85.78%). For identifying unknown individuals, ITS + matK had 100% correct identification rate based on our database, followed by ITS/ITS2 (both 93.33%) and ITS2 + matK (91.67%). Thus, we propose ITS/ ITS2 + matK as the most suitable barcode for invasive plants in China. This study also demonstrated that DNA barcoding is an efficient tool for identifying invasive species.

“…In this case, STLs with antiprotozoal activity have been reported from Mikania micrantha . Only a few reports seem to exist on the phylogenetic relationships of Mikania , but according to the phylogeny of Brazilian Mikania , M . trachypleura B.L.Rob would be the closest relative and one could assume that it produces STLs with similar properties.…”

Plants possess an outstanding chemical diversity of specialized metabolites developed to adapt to environmental niches and increase fitness. The observed diversity is hypothesized to result from various evolutionary mechanisms, such as the continuous branching off and extension of existing biosynthetic pathways or enhanced levels of catalytic promiscuity in certain enzymes. In this study, ChemGPS-NP has been employed to chart the distribution and diversity of physicochemical properties for selected types of specialized metabolites from the angiosperms. Utilizing these charts, it is analyzed how different properties of various types of specialized metabolites change in different plant groups, and the chemical diversity from the volume they occupy in chemical property space is evaluated. In this context, possible underlying evolutionary mechanisms are discussed, which could explain the observed distribution and behavior in chemical property space. Based on these studies, it is demonstrated that evolutionary processes in plant specialized metabolism and the resultant metabolic diversification are reflected in chemical property space.

“…These species have medicinal use with identical effects and are confused because of their similar morphology (Napimoga & Yatsuda, 2010). Molecular phylogeny separates these species, though, despite the evolutionarily closer proximity between them than to any other sampled species of the genus, with an estimated separation time of about 500,000 years only (Godoy et al, 2017).…”

Ecological networks describe community structure by focusing on how nodes are connected by links (interactions). Related species have higher probabilities of sharing links if interactions depending on phylogeny and/or species are functionally similar; however, if and how this modularity impacts higher trophic levels is still an open question. We aimed to evaluate the effect of different structuring factors on an observed bipartite network of galling insects and associated parasitoids on a system with two closely related and recently diverged plants, where host‐tracking could be underway. We hypothesized that gall structure, galler taxonomy and host plant identity could contribute, from a higher to a lower degree respectively, to network modularity by generating a selective pressure on parasitoids. Samples were collected between May 2015 and June 2017 in the forest areas of Porto Alegre, southern Brazil. Overall, we found 4629 galls of three monophagous and four oligophagous galling species; 664 parasitoid individuals were obtained and classified into 37 morphospecies. We constructed four networks with the collected data by organising nodes according to the tested factors, that is, gall structure, galler taxonomy, host plant identity and gall–plant interaction. All networks were significantly modular, and for three out of four analysed factors (gall structure, galler taxonomy and gall–plant interaction), modularity levels were at least intermediate (at about Q = 0.4). Barriers to or preferences for certain interactions appear to be responses to multiple concomitant factors. However, galler taxonomy and host plant identity are somehow stronger determinants for the parasitoids in terms of attacked hosts.
