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.
Results will show closest matches in our database, including name, collection number, voucher number, host (family or subfamily, genus and species) and geographic origin, as shown below.
