Additional description and genome analyses of Caenorhabditis auriculariae representing the basal lineage of genus Caenorhabditis

Abstract Caenorhabditis auriculariae, which was morphologically described in 1999, was re-isolated from a Platydema mushroom-associated beetle. Based on the re-isolated materials, some morphological characteristics were re-examined and ascribed to the species. In addition, to clarify phylogenetic re...
