Rust HUBB
​
​
When interpreting Blast results, in general, conspecificity will be indicated at >99% identity for rusts at this locus. Be sure to compare alignments -- genuine SNPs are more indicative of different species whereas polymorphic sites (Y/C/T) and poly-A/T sites may not be indicative of different species.
​
Results should be verified by microscopic examination.

Rust HUBB contains 28S DNA sequences from thousands of rust species. Sequences have been verified, and come from vouchered herbarium specimens.
​
For details on methods and primers for 28S sequencing, see Aime & McTaggart 2020.
To use this tool, select the Rust HUBB button at the right. Paste your 28S sequence into the box and blast.
