The work paved path for testing many other hypotheses. Shoutout to Samuel Holden & Meng Li who led the work with significant contributions from our collaborators. Last but not the least, shoutout to our funders - Genome BC
NSERC, SaskWheat SaskBarley, Alberta Grains, Manitoba Crop Alliance, WGRF.

We present first ever haplophased genome of barley stripe rust + an evidence for likely somatic hybridization event in Psh. Interestingly, Psh isn't much different from Pst & the difference is similar to what we find b/w two diverse Pst lineages+we found genes that makes Psh, Psh & not Pst. 3/5

My intuition from my MSc stripe rust work & what I hypothesized in 2018 - here we proved that I was right:
PstS18 - the most predominant stripe rust lineage in North America-is a somatic hybrid of PstS1 (former most predominant lineage that was introduced from east Africa around year 2000). 2/5

Wheat and barley stripe rust pan-genome facilitates discovery of the predominant North American lineage's origin in somatic hybridization Wheat and barley stripe rust, caused by Puccinia striiformis formae speciales tritici (Pst) and hordei (Psh) respectively is a perennial and endemic threat to those crops worldwide.

🌾A good day for cereal rust community!

Thrilled to share our 5 yrs of work with revolutionary discoveries on wheat & barley stripe rust fungi + we present the most comprehensive genomic resource (54 haploid genomes) ever developed for any wheat rust fungi.
