Visualizing trypanosome sex

Genetic exchange in Trypanosoma brucei is now well characterized. It is a key tool that has enabled an understanding of important parasite genetic traits and underpinned the Trypanosoma brucei genome project. However, a key aspect that has eluded us is the point in the trypanosome life cycle where genetic exchange occurs. Research using green and red fluorescent trypanosomes for visualizing genetic crosses has now identified this stage. [Copyright &y& Elsevier]
