Over the past years, zebrafish have proven to be excellent model systems for a wide panel of experiments. We have discussed throughout our previous articles their advantages and disadvantages, how they could be incorporated to various research fields and different automation techniques which facilitate their handling in laboratories. Today we will discuss 4 other model organisms: Drosophila melanogaster, Xenopus laevis, Caenorhabditis elegans and Arabidopsis thaliana, all have in common their genetic similarity to humans, their ease of care and prolific breeding. While this last feature is particularly useful for studies requiring…
