The genetic map of goldfish (Carassius auratus) provided insights to the divergent genome evolutions in the Cyprinidae family

A high-density linkage map of goldfish (Carassius auratus) was constructed using RNA-sequencing.
This map consists of 50 linkage groups with 8,521 SNP markers and an average resolution of 0.62 cM.
Approximately 84% of markers are in protein-coding genes orthologous to zebrafish proteins. We
performed comparative genome analysis between zebrafish and medaka, common carp, grass carp, and
goldfish to study the genome evolution events in the Cyprinidae family. The comparison revealed large

Phylogenetic and Evolutionary Analyses of the Frizzled Gene Family in Common Carp (Cyprinus carpio) Provide Insights into Gene Expansion from Whole-Genome Duplications

In humans, the frizzled (FZD) gene family encodes 10 homologous proteins that commonly
localize to the plasma membrane. Besides being associated with three main signaling pathways
for cell development, most FZDs have different physiological effects and are major
determinants in the development process of vertebrates and. Here, we identified and annotated
the FZD genes in the whole-genome of common carp (Cyprinus carpio), a teleost fish,
and determined their phylogenetic relationships to FZDs in other vertebrates. Our analyses

Enhancement of external quantum efficiency and quality of heterojunction white LEDs by varying the size of ZnO nanorods

The size of ZnO nanorods (NRs) plays an important role in tuning the external quantum efficiency (EQE) and quality of light generated by white light emitting diodes (LEDs). In this work, we report on the enhancement of EQE and the quality of ZnO NR-based hetrojunction white LEDs fabricated on a p-GaN substrate using a low temperature solution method. Cathodoluminescence spectra demonstrate that ultraviolet (UV) emission decreases and visible deep band emission increases with an increase in the length of the ZnO NRs.
