Population structure and genetic diversity of Phakopsora pachyrhizi in the Southeastern United States.

ABSTRACT: Phakopsora pachyrhizi, the causal agent of soybean rust disease (SBR) on Glycine max (soybean), is considered one of the most globally devastating diseases of soybeans and is a particular problem in Brazil, China, Sub-Saharan Africa, and the southern United States. To better understand genetic diversity and epidemiological history of SBR in the United States, 49 P. pachyrhizi isolates collected from soybean fields in four Southeastern states (Alabama, Florida, Georgia, and Louisiana) from the 2008 to 2017 growing seasons were genotyped through restriction site-associated genotype by sequencing (GBS). Rarefaction analysis identified 54 informative SNPs among the P. pachyrhizi isolates. We found no evidence suggesting sexual or parasexual recombination, and measurements of genetic diversity
