Progress of studies on reproductive modes and mechanisms of regulation in Artemia
The reproductive mode and its regulating mechanism is one of the most fundamental and important issues concerned in life sciences.The genus Artemia is a group of small crustaceans that have significant economic and scientific research values.According to reproductive modes,Artemia has eight bisexual species and quite a few geographic parthenogenetic populations,providing an ideal research model for the study of the mechanism of reproduction.Previous studies on the reproductive regulation in Artemia have been focusing on discrimination of bisexual species and parthenogenetic populations,chromosomal karyotyping,interspecific hybridization,biogeography,population genetics,etc.,which sometimes led to disputed results.In recent years,with more and more accumulated evidence and the accomplishment of the whole Artemia genomes,research interests on sex determination and origin of parthenogenesis have gradually converged towards a unified focus on gene expression regulation at the genomic level.In this context,this paper summarizes the research history and frontier of the mechanism of reproduction in Artemia,and combines the research and considerations of our team to sort out the information of sex regulation mechanisms of both bisexual and parthenogenetic Artemia.We also look forward to future research directions and the problems to be solved.
