The chemical ecology of cyanobacteria [PDF]

open access: yesNatural Product Reports, 2012
This review covers the literature on the chemically mediated ecology of cyanobacteria, including ultraviolet radiation protection, feeding-deterrence, allelopathy, resource competition, and signalling. To highlight the chemical and biological diversity of this group of organisms, evolutionary and chemotaxonomical studies are presented.

Potential distribution of fall armyworm in Africa and beyond, considering climate change and irrigation patterns

open access: yesScientific Reports, 2022
The fall armyworm, Spodoptera frugiperda (FAW), first invaded Africa in 2016 and has since become established in many areas across the continent where it poses a serious threat to food and nutrition security. We re-parameterized the existing CLIMEX model

Determining the scale at which variation in a single gene changes population yields

open access: yeseLife, 2020
Plant trait diversity is known to influence population yield, but the scale at which this happens remains unknown: divergent individuals might change yields of immediate neighbors (neighbor scale) or of plants across a population (population scale).

Phosphorylation via PKC regulates the function of the Drosophila odorant coreceptor

open access: yesFrontiers in Cellular Neuroscience, 2011
Insect odorant receptors (ORs) have a unique design of heterodimers formed by an olfactory receptor protein and the ion channel Orco. Heterologously expressed insect ORs are activated via an ionotropic and a metabotropic pathway that leads to cAMP ...

The nitrilase PtNIT1 catabolizes herbivore-induced nitriles in Populus trichocarpa

open access: yesBMC Plant Biology, 2018
Background Nitrilases are nitrile-converting enzymes commonly found within the plant kingdom that play diverse roles in nitrile detoxification, nitrogen recycling, and phytohormone biosynthesis.

Metabolomics in chemical ecology

open access: yesNatural Product Reports, 2015
Metabolomics has emerged as powerful tool in the elucidation of natural products as mediators of organismal interactions. This review comprehensively highlights successful applications and perspectives of metabolomics in chemical ecology.

microRNA390 modulates Nicotiana attenuata's tolerance response to Manduca sexta herbivory

open access: yesPlant Direct, 2021
miR390 is a highly conserved miRNA in plant lineages known to function in growth and development processes, such as lateral root development, and in responses to salt and metal stress.

Calmodulin affects sensitization of Drosophila melanogaster odorant receptors

open access: yesFrontiers in Cellular Neuroscience, 2016
Flying insects have developed a remarkably sensitive olfactory system to detect faint and turbulent odor traces. This ability is linked to the olfactory receptors class of odorant receptors (ORs), occurring exclusively in winged insects.

The hermit crab’s nose – antennal transcriptomics

open access: yesFrontiers in Neuroscience, 2014
In the course of evolution, crustaceans adapted to a large variety of habitats. Probably the most extreme habitat shift was the transition from water to land, which occurred independently in at least five crustacean lineages.

Functional olfactory sensory neurons housed in olfactory sensilla on the ovipositor of the hawkmoth Manduca sexta.

open access: yesFrontiers in Ecology and Evolution, 2016
Olfactory systems evolved to detect and identify volatile chemical cues, in many cases across great distances. However, the precision of copulatory and oviposition behaviors suggest that they may be guided by olfactory cues detected by sensory systems ...
