DOI: 10.1002/open.202500359
Abstract: Major secondary metabolites of Physalis plants, epoxidized withanolides, have a potent feeding deterrent and growth inhibitory effect on most herbivorous insects. Caterpillars of the specialist moth species Heliothis (Chloridea) subflexa consume only Physalis fruits, whereas… read more here.

DOI: 10.1007/s10886-018-1038-x
Abstract: Phenolics have a role in defenses against herbivores, but the defensive functions of specific groups of phenolics are still poorly understood. For example, ellagitannins (a type of hydrolyzable tannin) are predicted to decrease insect herbivore… read more here.

DOI: 10.1017/s0007485317000529
Abstract: Abstract Thiamine is a vitamin that has been shown to act as a trigger to activate plant defence and reduce pathogen and nematode infection as well as aphid settling and reproduction. We have here investigated… read more here.

DOI: 10.1038/s42003-024-07446-1
Abstract: Leaf endospheres harbor diverse bacterial communities, comprising generalists and specialists, that profoundly affect ecosystem functions. However, the ecological dynamics of generalist and specialist leaf-endophytic bacteria and their responses to climate change remain poorly understood. We… read more here.

DOI: 10.1093/beheco/arac114
Abstract: Abstract Background-matching camouflage is a well-established strategy to reduce detection, but implementing this on heterogeneous backgrounds is challenging. For prey with fixed color patterns, solutions include specializing on a particular visual microhabitat, or adopting a… read more here.
