The sperm, a neuron with a tail: 'neuronal' receptors in mammalian sperm

Article Abstract:

The evidence regarding the presence of sperm plasma membrane 'neuronal' receptors and of their significance to mammalian sperm function is reviewed. The persuasiveness of the evidence varies depending on the receptor being considered, but there is strong experimental support for the presence and importance of a number of 'neuronal' receptors in sperm.

Cophylogeny of the Ficus microcosm

Article Abstract:

The results of cophylogeny analysis concerning Ficus are reviewed and the plausibility of different evolutionary events is discussed. The results support the consensus that figs codiverge significantly with pollinators but not with non-pollinators.
