Database Selection Guide

BMCBase offers three specialized gene databases; please choose the one that best suits your research environment:

🌿 Mangrove Gene Database (Mangrove Gene Database)

Suitable for research: Mangrove ecosystems, intertidal zones, and salt-tolerant plant rhizosphere microorganisms

Distinctive genes: Contains genes related to salt tolerance, antioxidant activity, and organic matter degradation unique to mangroves

Recommended use: Ideal for studies involving mangrove sediments, rhizosphere soils, and phyllosphere microbial communities

🌊 Saltmarsh Gene Database (Saltmarsh Gene Database)

Suitable for research: Salt marsh wetlands, high-salinity environments, and extremophile microorganisms

Distinctive genes: Rich in genes associated with extreme salt tolerance, osmotic regulation, and sulfur cycling

Recommended use: The top choice for researching salt lakes, salt marshes, and microorganisms in high-salinity seawater environments

🌱 Seagrass Gene Database (Seagrass Gene Database)

Suitable for research: Seagrass bed ecosystems, marine sediments, and marine plant microbiomes

Distinctive genes: Encompasses genes related to the seagrass rhizosphere, marine carbon and nitrogen cycles, and marine primary production

Recommended use: Recommended for studies of seagrass bed sediments and the rhizosphere of marine plants

Usage Instructions

  1. Select Database: Use the "Select Comparison Database" dropdown menu to choose the database that best suits your research environment
  2. Enter Sequence: Paste your sequence in the textbox or select a FASTA file using the "Upload File" option
  3. Set Parameters: Choose the BLAST program (blastp for protein sequences, blastx for DNA sequences)
  4. Adjust Thresholds: Modify the E-value threshold and maximum target sequence count as needed
  5. Run Search: Click "Run BLAST" to start the alignment; it usually takes 1-2 minutes

Features

Users can upload sequence files (e.g., .fa, .fasta, .faa, .txt formats) or directly enter sequence data to perform BLAST-based searches on the gene catalogs in the database, with the option to use either BLASTX or BLASTP mode.

  • Supports multiple sequence input formats (FASTA, plain text)
  • Offers three specialized ecological gene databases
  • Automatically filters out low similarity results (<50% similarity)
  • Supports exporting results in TSV format
  • Displays search progress and parameter information in real-time

Tips

  • Select the appropriate database: Choose the database corresponding to your sample's environment to significantly improve matching accuracy
  • Sequence Length: It is recommended to use sequences longer than 50 amino acids or 150 nucleotides for the search
  • E-value Settings: For conserved sequences, use a stricter threshold (1e-10), and for novel sequences, relax it to 1e-3
  • Interpreting Results: Prioritize results with over 70% similarity, as these typically have higher functional relevance
