Evolutionary Changes of GT1 Provide Insights Into the Adaptation of Butterflies to Plant Feeding

open access: yesEcology and Evolution, Volume 15, Issue 11, November 2025.
We investigated the evolution of glycosyltransferase 1 (GT1) genes in 69 butterfly species to explore their association with host plant adaptation. Our results reveal frequent tandem duplications and adaptive selection in GT1s, especially in UGT33 and UGT40 subfamilies, alongside expression patterns suggesting functional diversification.

Independent evolution of ancestral and novel defenses in a genus of toxic plants (Erysimum, Brassicaceae)

open access: yeseLife, 2020
Phytochemical diversity is thought to result from coevolutionary cycles as specialization in herbivores imposes diversifying selection on plant chemical defenses.

Mate Choice and Toxicity in Two Species of Leaf Beetles with Different Types of Chemical Defense [PDF]

open access: yes, 2018
Evidence for the use of defensive compounds for sexual purposes is scarce, even though sexual selection might have some importance for the evolution of defensive traits. This study investigates the effect of defense-related traits and body size on mating

Messages from the other side: parasites receive damage cues from their host plants [PDF]

open access: yes, 2016
As sessile organisms, plants rely on their environment for cues indicating imminent herbivory. These cues can originate from tissues on the same plant or from different individuals.

Honest signalling in predator–prey interactions: Testing the resource allocation hypothesis

open access: yesFunctional Ecology, Volume 39, Issue 10, Page 2833-2848, October 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Warning signals are honest if they reliably deliver information about prey unprofitability to predators. One potential mechanism that may create and maintain a positive relationship between the strength of signals and defence is the resource allocation between these ...

From WGS to gels: Development and testing of PCR primers targeting toxic Digitalis in support of food safety

open access: yesApplications in Plant Sciences, Volume 13, Issue 5, September-October 2025.
Abstract Premise This study capitalized on a library of single‐nucleotide polymorphisms created via whole genome sequencing (WGS) to develop and test a PCR assay for detecting toxic Digitalis species in food products. Complex foods can be difficult to analyze, but safeguarding consumer well‐being and public health necessitates that products regulated ...

Both synergism and interaction diversity explain the mixtures of defensive monoterpenes in spruce oleoresin

open access: yesFunctional Ecology, Volume 39, Issue 9, Page 2539-2551, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Chemical defences, such as the monoterpenes of conifer oleoresin, frequently occur as complex blends of many components, but the selective pressures that maintain these mixtures are not yet known.
