“…Future studies aiming at the identification of the metabolites responding to herbivory combined with bioassay‐guided fractionation will provide insights in their potential defensive functions in S. latifolia . Such studies could target putative defence compounds previously detected in the genus Silene, such as phytoecdysteroids that impair the development of insect larvae, or triterpene saponins that interfere with nutrient resorption in the intestinal membrane of insects (Mamadalieva, Lafont, & Wink, ).…”

Inbreeding diminishes herbivore‐induced metabolic responses in native and invasive plant populations

Inbreeding and herbivory can interactively reduce the performance of flowering plants. Here, we investigated whether the magnitude of plant inbreeding depression increases under herbivory as a result of diminished leaf metabolic responses to herbivory in inbreds, which entails increased herbivore growth and feeding damage. We additionally explored whether genetic differentiation among native and invasive plant populations impacts the magnitude and direction of these inbreeding × herbivory interactions. Inbred and outbred plants from eight European (native) and eight North American (invasive) populations of Silene latifolia were exposed to two consecutive control or herbivory treatments (infestation with larvae of Mamestra brassicae). After the first treatment, leaf metabolic responses to herbivory were assessed with untargeted metabolic fingerprinting using UHPLC‐ESI+‐QTOF‐MS/MS. After the second herbivory treatment, herbivore growth and plant feeding damage were assessed. Moreover, plant performance traits were recorded 4 weeks after the second herbivory treatment. Metabolic fingerprinting revealed that changes in the pool sizes of various metabolic features in response to herbivory were less intense in inbred than outbred plants from native and invasive populations. While herbivore growth and feeding damage were largely unaffected by plant breeding status in invasive populations, herbivores consumed more biomass from, but showed reduced growth on, inbred than outbred native plants. The magnitude of inbreeding depression in plant performance traits was not affected by herbivory. Synthesis. Our findings suggest that inbreeding compromises herbivory‐induced metabolic defences in S. latifolia, and simultaneously reduces the nutritional quality of plants. The magnitude and direction of these inbreeding effects were shaped by genetic differentiation among native and invasive plants. These range‐specific responses provide novel insights into the role of inbreeding x herbivory interactions in invasion success.

“…Many species within the genus Silene s.l. are described as particularly rich in phytoecdysteroids of diverse structure (93 different compounds reported), being perhaps their richest source in the entire plant kingdom (Speranza, 2010;Mamadalieva, 2012;Mamadalieva et al, 2014). Previous studies have led to the isolation and identification of eleven ecdysteroids present in L. flos-cuculi.…”

Taxonomy Secondary metabolites Biological activity In vitro cultures Micropropagation A B S T R A C T Lychnis flos-cuculi L., Caryophyllaceae, contains a number of active compounds belonging to several chemical groups. Previous studies have led to the identification of phytoecdysteroids, triterpenoids saponins, volatile compounds, fatty acid derivatives, phenolic acids and flavonoids. Research on pharmacological activity showed that plant extracts inhibited the growth of bacteria and fungi. The antimitotic properties of preparations from the herb L. flos-cuculi were also reported. The phytochemical analyses demonstrated that this taxon contains pharmaceutically promising compounds, but more phytochemical and pharmacological studies of L. flos-cuculi are needed for further information regarding this plant. This review summarizes reports regarding chemical composition and biological activity of L. flos-cuculi as well as several cognate species, which pose opportunities related to in vitro propagation and cell and tissue cultures. In vitro-regenerated plantlets could be a good source of genetically uniform plant material for future research.

The EICA‐hypothesis predicts that invading plants adapt to their novel environment by evolving increased performance and reduced resistance in response to the release from natural enemies, and assumes a resource allocation tradeoff among both trait groups as mechanistic basis of this evolutionary change. Using the plant Silene latifolia as a study system, we tested these predictions by investigating whether 1) invasive populations evolved lower resistance and higher performance, 2) this evolutionary change is indeed adaptive, and 3) there is a negative genetic correlation between performance and resistance (i.e. a tradeoff) in native and introduced individuals. Moreover, we sampled eight native and eight invasive populations and determined their population co‐ancestry based on neutral SSR‐markers. We performed controlled crossings to produce five sib‐groups per population and exposed them to increased and reduced levels of enemy attack in a full‐factorial experiment to estimate performance and resistance. With these data, we performed trait‐by‐trait comparisons between ranges with ‘animal models’ that account for population co‐ancestry to quantify the amount of variance in traits explained by non‐adaptive versus adaptive evolution. Moreover, we tested for genetic correlations among performance and resistance traits within sib‐groups. We found significant reductions in resistance and increases in performance in invasive versus native populations, which could largely be attributed to adaptive evolution. While we detected a non‐significant trend towards negative genetic performance × resistance correlations in native populations, invasive populations exhibited both significant and non‐significant positive correlations. In summary, these results do not support a shift of performance and resistance trait values along a tradeoff line in response to enemy release, as predicted by EICA. They rather suggest that the independent evolution of both traits is not constrained by a tradeoff, and that various selective agents (including resource availability) interact in shaping both traits and in weakening negative genetic correlations in the invaded habitat.
