In the past decade, intensive research has been conducted on the model organism Pristionchus pacificus and the genus Pristionchus, focusing on development, evolution, ecology, behavior, neurobiology, and genomics. Asia is identified as a biodiversity hotspot for Pristionchus worms. Nine new Pristionchus species were isolated in Mainland China through morphology, morphometrics, mating experiments, and genome-wide sequence analysis.
The model organism Pristionchus pacificus and the genus Pristionchus, Kreis, 1932 have been intensively studied in the last decade with contemporary work focusing on the development, evolution, ecology, behavior, neurobiology, and genomics of this group of organisms. In particular, mechanistic studies on the development and evolution of mouth-form plasticity, predation and associated self-recognition processes enabled unique insight into life history strategies and the evolution of novelty. These studies include a comparative research agenda making use of the 39 available species of Pristionchus, all of which can be studied in living cultures. Sampling efforts revealed that Asia represents a biodiversity hotspot for Pristionchus worms. However, previous samplings have a bias towards northern and island areas, largely for logistic reasons. Here, we report on two extensive sampling trips to the Yunnan and Shaanxi provinces in Mainland China. We report the isolation of nine new Pristionchus species by morphology, morphometrics, mating experiments and genome-wide sequence analysis.
