CCNU Made a Breakthrough in Genome Deciphering

Revision:Xiong Kewei, Zhang Qi, Hu ZhaoxinDate:2019/12/10

Professor Wu Hua’s research team from the School of Life Sciences of CCNU made a significant breakthrough in the field of sexually dimorphic nuptial spines in leptobrachium leishanense on the basis of molecule, and the relevant paper is published in "Nature Communications".

Sexual dimorphism refers to discrepancies of size, shape and color demonstrated by conspecific individuals with different sex, the issues of which has been a hot issue for evolutionary biologists. Wu’s team discover the molecular formation mechanism of sexual dimorphism, taking leptobrachium leishanense as an experimental subject. They obtain the genome sequence by assembling ultimately.

Researchers identified a module of co-expressed genes significantly associated with spine formation. In addition, several hormones likely to be involved in regulating spine development were found. This study not only presents a high-quality anuran genome but also provides a reference for studying skin-derived SD traits in amphibians.

Ph.D. candidate Li Jun is the first author and Professor Wu Hua is the corresponding author. The research is supported by the National Natural Science Foundation of China and the Ministry of Ecology and Environment of the People’s Republic of China.
