The stability of fatty acid composition in sunflower oil is dependent on environment and affected by structural variation

Markus Ingold, Qing-Ming Gao, Jennifer R. Mandel, James P. McNellie, Kyle G. Keepers, Jessica G. Barb, John M. Burke, Loren H. Rieseberg, Brent S. Hulke

This study identifies genetic loci associated with fatty acid composition stability in sunflower across environments using GWAS and finds a large introgression linked to stability under high heat.

Variant filters using segregation information improve mapping of nectar-production genes in sunflower (Helianthus annuus L.)

Ashley C. Barstow, James P. McNellie, Brian C. Smart, Kyle G. Keepers, Jarrad R. Prasifka, Nolan C. Kane, Brent S. Hulke

This paper improves variant calling in sunflower by using segregation-based filtering, leading to better QTL mapping and identification of nectar-related genes.
