A key step in sexual reproduction is the fusion of haploid cells to form a diploid zygote, yet the molecular mechanism underlying this joining of cells is poorly understood. Two studies reveal amazing similarities between proteins required for fusion of sperm and egg, and virus with host cells. A screen for genes that cause male sterility in the flowering plant Arabidopsis led to …
The TWiVirions reveal bacteriophage genes that control eukaryotic reproduction, and the biochemical basis for increased Ebolavirus glycoprotein activity during the recent outbreak.

The obligate intracellular bacteria Wolbachia (pictured), which infects 40% of arthropods, can manipulate its host to ensure its maintenance in the population. An example is cytoplasmic incompatibility, which occurs when infected males mate with uninfected females, and causes embryonic lethality (mating with an infected female produces viable offspring). Two Wolbachia genes responsible for this phenotype have been …
The TWiX cabal discuss sexual transmission of Zika virus in mice, and how immune escape enables herpes simplex virus escape from latency. You can find TWiV #430 at microbe.tv/twiv, or listen below.
