... are largely unknown. To better understand how host cues affect P. pacificus embryogenesis, we characterized the threshold of sensitivity to the pheromone ( Z )-7-tetradecen-2-one (ZTDO) by determining the minimum exposure duration and developmental window that results in P. pacificus embryonic lethality. We...

Machado SUMMARY This study examined the process of membrane fusion of yolk granules (YGs)during early embryogenesis of Rhodnius prolixus . We show that eggs collected at days 0 and 3 after oviposition...

... the fish olfactory system is established during embryogenesis it is simple in its organization, with few olfactory neurons and an olfactory epithelium that has not yet folded into the adult morphology. It is possible that positional cues might act in the embryo to establish an initial population...

... examined the development of identified heart excitor (HE) motor neurons during normal embryogenesis. Using intracellular impalements and dyefilling, we found that the HE motor neurons could be identified at an early stage of development and that they initially elaborated axonal arborizations...

... is that a basic segmentally-repeated pattern arises during embryogenesis: a stereotyped axonal scaffold upon which growth cones faithfully fasciculate. Evolutionary plasticity allows the specialization of lineally equivalent neurones in different segments within the context of the neuropilar neighbourhood...
