SSU区域的引物覆盖情况

This page lists an overview of the coverage and additional information for SSU primers and primer pairs. The coverage information can be viewed either as “% in Species” or “% in Sequences”. Specific terms are defined as follows:

• Length = The primer length, measured in base pairs
  
  

• Coverage % in Sequences = The percent of sequences covered within this taxon, considering four conditions: (1) all three domains (All), (2) Bacteria only (Bacterial %), (3) Archaea only (Archaeal %), or (4) Eukaryota only (Eukaryotic %). It’s calculated with the equation {number of sequences within this taxon that can be amplified using the specified primer pair} / {total number of sequences in the database* from this taxa}

  
  

• Coverage % in Species = The percent of species covered within this taxon, considering four conditions: (1) all three domains (All), (2) Bacteria only (Bacterial %), (3) Archaea only (Archaeal %), or (4) Eukaryota only (Eukaryotic %). It’s calculated with the equation {number of species within this taxon that produce at least one amplicon using the specified primer pair} / {total number of species in the database* from this taxa}

  
  

• Amplicon Length = The average length of all amplicon sequences produced by the specific primer pair
