Rust HUBB
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, Aime et al. 2018, and Aime 2006.
To use this tool, select the Rust HUBB button at the right. Paste your 28S sequence into the box and blast.

​
When interpreting Blast results, in general, conspecificity will be indicated at >99% identity for rusts at the 28S 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 at this locus.
​
Results should be verified by microscopic examination.
Herbarium codes: PUR = Arthur Fungarium, Purdue University; BPI = US National Fungus Collections, Beltsville, MD; LSUM = Louisiana State University Massey Herbarium, Baton Rouge, LA; BUT = Butler University Herbarium, Indianapolis, IN; BRIP = Plant Pathology Herbarium, Queensland, Australia.
