Area of Science:
- Genomics
- Bioinformatics
- Evolutionary Biology
Background:
- The initial Fish Transposable Element Database (FishTEDB 1.0) was launched in 2018.
- FishTEDB 1.0 has served approximately 10,000 users over five years.
- Increasing fish genome data and TE research necessitate database expansion.
Purpose of the Study:
- To release an updated version of the fish transposable element database, FishTEDB 2.0.
- To enhance data richness and functionality for transposable element research.
- To support future studies on transposable element functions and biological theories.
Main Methods:
- Incorporated data for 33 new fish species, representing 48 orders.
- Added a genome browser for visualizing TE-gene positional relationships.
- Integrated TE insertion time estimation across different species.
Main Results:
- FishTEDB 2.0 significantly expands the number of fish species covered.
- The new genome browser provides crucial visualization tools.
- Enhanced functional capabilities facilitate deeper analysis of transposable elements.
Conclusions:
- FishTEDB 2.0 is a valuable resource for the scientific community.
