Flavin-dependent monooxygenases as a detoxification mechanism in insects: new insights from the arctiids (lepidoptera). [PDF]

PLoS ONE, 2010
Insects experience a wide array of chemical pressures from plant allelochemicals and pesticides and have developed several effective counterstrategies to cope with such toxins.

Biochemical and Molecular Insights Into Monocrotaline‐Induced Hepatotoxicity: An Experimental Mouse Study

Journal of Applied Toxicology, EarlyView.
ABSTRACT Monocrotaline (MCT), a plant‐derived pyrrolizidine alkaloid, is well known for its hepatotoxic effects. However, full elucidation of the mechanisms underlying MCT‐induced hepatotoxicity, as well as the development of reliable biomarkers for early detection and monitoring, requires an integrated evaluation of biochemical, molecular, and ...

Bee pollen as functional food and environmental bioindicator: current evidence and future challenges

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Bee pollen (BP), a plant‐derived product collected by honey bees, is increasingly promoted as a functional food due to its content of proteins, essential amino acids, lipids, vitamins, minerals, and bioactive compounds such as polyphenols and flavonoids.

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

Journal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Observation of Trigona recursa Smith (Hymenoptera: Apidae) Feeding on Crotalaria micans Link (Fabaceae: Faboideae) in a Brazilian Savanna Fragment

Sociobiology, 2013
In this paper we present observations of individuals of the bee species Trigona recursa feeding on the fruits of Crotalaria micans. This plant, which contains pyrrolizidine alkaloids, is known to be toxic to humans, mammals and poultry.

Quantitative analysis of total retronecine esters-type pyrrolizidine alkaloids in plant by high performance liquid chromatography

, 2007
Pyrrolizidine alkaloids (PAs) are alkaloids which typically contain a necine (7-hydroxy-1-hydroxymethyl-6,7-dihydro-5H-pyrrolizidine) base unit, and they can be found in one third of the higher plants around the world. They are hepatotoxic, mutagenic and
