Project description:We applied high throughput sequencing technology to identify microRNA genes in bighead carp and silver carp. We identified 167 conserved miRNAs in bighead carp and 166 in silver carp. By two computational stragegies, we obtained 39 novel miRNAs in bighead carp and 54 in silver carp, for which, no homologs were found in other species. Several miRNA* sequences were found in our dataset as well, some particular ones might have gene regulation function. Gain and loss of family members were observed in several miRNA families, which partially reflected the fate of miRNA gene duplicates.

Total RNA of juvenile bighead carp and silver carp were sequenced on one Solexa lane, respectively.
Project description:China produces more than 77.9% of the world's production of silver carp in 2020 with the production of 3812.9 kiloton.3 The high consumption of silver carp in China is mainly by using its edible muscles for manufacture of surimi-based seafoods or other muscle foods, which may contribute high quality protein resource and other valuable nutrients in human diets. This project is to understanding the muscle composition of slaughtered fish skeletal muscle use the proteomics methods. The proteomics was performed based on the improved DDA experiment with extensive fractionation and prolonged separation of peptides, and protein searching database was informed by the Iso-seq transcriptomics.
Project description:Silver-resistant Saccharomyces cerevisiae mutant was obtained by evolutionary engineering method. Briefly, genetic diversity in reference strain, CEN.PK.113-7D, was increased by ethyl methane sulfonate (EMS)-mutagenesis. The mutant population was passaged several times in gradually increasing silver stress. Several mutant individuals were selected from the final population. Among selected mutant individuals, one of them was much more resistant to silver stress than the reference strain, called as 2E. Whole-genome transcriptomic analysis was performed to identify the silver resistance mechanisms in the silver-resistant mutant strain.
