Identification of new resistance loci to African stem rust race TTKSK in tetraploid wheats based on linkage and genome-wide association mapping

Laido, Giovanni; Panio, Giosue; Marone, Daniela; Russo, Maria A; Ficco, Donatella B. M.; Giovaniello, Valentina; Cattivelli, Luigi; Steffenson, Brian; De Vita, Pasquale; Mastrangelo, Anna M (Frontiers in Plant Science, 2015-12-09)
Stem rust, caused by Puccinia graminis Pers. f. sp. tritici Eriks. and E. Henn. (Pgt), is one of the most destructive diseases of wheat. Races of the pathogen in the “Ug99 lineage” are of international concern due to their ...

Barley stem rust resistance genes: structure and function

Steffenson, Brian; Kleinhofs, Andris; Brueggeman, Robert; Nirmala, Jayaveeramuthu; Zhang, Ling; Mirlohi, Aghafakhr; Druka, Arnis; Rostoks, Nils (Plant Genome, 2009-07)
Rusts are biotrophic pathogens that attack many plant species but are particularly destructive on cereal crops. The stem rusts (caused by Puccinia graminis) have historically caused severe crop losses and continue to ...

Rice-barley synteny and its applications to saturation mapping of the barley Rpg1 region

Steffenson, Brian; Kilian, Andrzej; Kudrna, David A.; Kleinhofs, Andris; Yano, Masahiro; Kurata, Nori; Sasaki, Takuji (Nucleic Acids Research, 1995-07-25)
In order to facilitate the map-based cloning of the barley stem rust resistance gene Rpg1, we have demonstrated a high degree of synteny at a micro level between the telomeric region of barley chromosome 1P and rice ...

Puccinia coronata var. hordei var. nov. morphology and pathogenicity

Steffenson, Brian; Jin, Y. (Mycologia, 1999)
A new variety of Puccinia coronata causing a disease on barley and other gramineous species is described. The fungus is different from other reported forms of P coronata in both morphology and pathogenicity. Its most ...

Genetic and molecular characterization of mating type genes in Cochliobolus sativus

Steffenson, Brian; Zhong, Shaobin (Mycologia, 2001-09-01)
Genetic and molecular approaches were used to characterize the mating type (MAT) genes in Cochliobolus sativus. One hundred and four ascospore progeny derived from a cross of C. sativus isolates ND93-1 (MAT-1) X ND9OPr ...
