Consolidation of long-term courtship memory in Drosophila is mediated by a novel class of sleep promoting neurons that reactivates dopaminergic neurons engaged earlier in memory acquisition during post-learning sleep.
The colonization of corals and their relatives by intracellular microalgae is facilitated by immunity proteins in the animal that contain thrombospondin-type-1 repeats, elucidating the inter-partner recognition processes required for the establishment of this ecologically important symbiosis.
Host CD81 and Scavenger Receptor BI operate independently to mediate invasion of hepatocytes by different species of Plasmodium sporozoites, which use the parasite protein P36 as a key determinant of the entry route.
Cytokinin-dependent manipulation of plant metabolism is a strategy employed not only by gallers and leaf-miners but also by a free-living insect, Tupiocoris notatus, which directly transfers cytokinins at feeding sites to manipulate its host plant.
Parallel losses of short-wave light sensitivity in diverse bats occurred through independent changes at multiple steps in the conversion of genotype into functional phenotype, including pre-, during, and post-transcription.
