Research advances on animal genetics in China in 2015.

Bo Z , Xiaofang C , Xun H , Xiao Y .

Chinese scientists have made significant achievements in the field of animal genetics in 2015. Incomplete statistics show that among all the publications of 2015 involving nematode (Caenorhabditis elegans), fly (Drosophila melanogaster), zebrafish (Danio rerio), African clawed frog (Xenopus) or mice (Mus musculus), about 1/5 publications are from China. Many innovative studies were published in high-impact international academic journals by Chinese scientists, including the identification of a putative magnetic receptor MagR, the genetic basis for the regulation of wing polyphenism in the insect brown planthopper (Nilaparvata lugens), DNA N(6)-methyladenine (6mA) modification in the Drosophila genome, a novel molecular mechanism regarding the dendritic spine pruning and maturation in the mammals, the mechanism for the CREB coactivator CRTC2 in the regulation of hepatic lipid metabolism, the control of systemic inflammation by neurotransmitter dopamine, the role of Gasdermin protein family in triggering pyroptosis, a parvalbumin-positive excitatory visual pathway to trigger fear responses in mice, etc. Chinese scientists have also made important contributions in genome editing via TALEN or CRISPR/Cas system. According to incomplete statistics, more than 1/5 of the publications related to genome editing in 2015 are from China, where a variety of animals with different approaches were targeted, ranging from the worm to primates. Particularly, CRISPR/Cas9-mediated gene editing in human tripronuclear zygotes was successfully achieved for the first time. China has been one of the leading countries in genome sequencing in recent years, and Chinese scientists reported the sequence and annotation of the genomes of several important animal species in 2015, including goose (Anser cygnoides), Schlegel''s Japanese Gecko (Gekko japonicus), grass carp (Ctenopharyngodon idellus), large yellow croaker (Larimichthys crocea) and pig (Sus scrofa). They further analyzed the genome-wide genetic basis of the species-specific physiological and pathological characteristics as well as their adaptation to environmental conditions. In this review, we make a first attempt to summarize the research advances on animal genetics in China in 2015, with an emphasis on the achievements led by Chinese scientists and carried out in Chinese institutions. We will briefly discuss the significance of their research and contributions of Chinese scientists in animal genetics.
