FishTEDB 2.0: an update fish transposable element (TE) database with new functions to facilitate TE research

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.
• The updated database will accelerate research in fish genomics and transposable element biology.
• This resource promotes advancements in biological theories related to transposable elements.
