The ability of Manduca moths to recognize changes in the profile of volatile compounds released by plants being attacked by Manduca caterpillars allows them to lay their eggs on plants that are less likely to be attacked by insects and other predators, and to avoid competing against other caterpillars of the same species for resources.
A 2-year field study has demonstrated that volatile compounds produced by plants when they are attacked by herbivores act as defenses by attracting predators to the herbivores and increasing the reproduction of the plants.
Both the frequency of sesquiterpene-emitting individuals and the defense capacity of individual plants determine the consequences of sesquiterpene volatile emission for individuals and their neighbors in populations of the wild tobacco Nicotiana attenuata.
A plant virus, Tomato yellow leaf curl virus, manipulates the host preference of the vector insect whitefly to promote its transmission by inducing caspase-dependent apoptotic neurodegeneration in vector's brain.
The olfactory learning of Caenorhabditis elegans shows that the exonuclease and helicase domains of human Werner syndrome protein (WRN) coordinately regulate the biogenesis of small interfering RNAs to promote neuronal plasticity.
A genetic analysis has identified the cholinergic SIA sublateral motor neurons, which innervate all four body wall muscles separately, as crucial regulators of turning around during sleep in Caenorhabditis elegans.
