Journal ArticleDOI
Validation of a candidate deoxynivalenol-inactivating UDP-glucosyltransferase from barley by heterologous expression in yeast
Wolfgang Schweiger,Jayanand Boddu,Sanghyun Shin,Brigitte Poppenberger,Brigitte Poppenberger,Franz Berthiller,Marc Lemmens,Gary J. Muehlbauer,Gerhard Adam +8 more
TL;DR: Evidence is presented that the product of the TaUGT3 gene recently proposed to encode a DON-detoxification enzyme of wheat does not protect yeast against DON, and four candidate barley glucosyltransferases, which are highly DON inducible, are tested.
Journal ArticleDOI
Breeding strategies and advances in line selection for Fusarium head blight resistance in wheat
Barbara Steiner,Maria Buerstmayr,Sebastian Michel,Wolfgang Schweiger,Marc Lemmens,Hermann Buerstmayr +5 more
TL;DR: The importance of morphological traits like the extent of retained anthers after flowering, its suitability for indirect selection and the pronounced association of the semi-dwarfing allele Rht-D1b with increased anther retention and FHB severity are discussed.
Journal ArticleDOI
Transcriptomic characterization of two major Fusarium resistance quantitative trait loci (QTLs), Fhb1 and Qfhs.ifa‐5A, identifies novel candidate genes
Wolfgang Schweiger,Barbara Steiner,Christian Ametz,Gerald Siegwart,Gerlinde Wiesenberger,Franz Berthiller,Marc Lemmens,Haiyan Jia,Gerhard Adam,Gary J. Muehlbauer,David P. Kreil,David P. Kreil,Hermann Buerstmayr +12 more
TL;DR: A uridine diphosphate (UDP)‐glycosyltransferase gene, designated TaUGT12887, exhibiting a positive difference in response to the pathogen in lines harbouring both QTLs relative to lines carrying only the Qfhs.ifa‐5A resistance allele is identified, suggesting Fhb1 dependence of this transcript.
Journal ArticleDOI
Suppressed recombination and unique candidate genes in the divergent haplotype encoding Fhb1, a major Fusarium head blight resistance locus in wheat
Wolfgang Schweiger,Barbara Steiner,Sonia Vautrin,Thomas Nussbaumer,Gerald Siegwart,M. Zamini,F. Jungreithmeier,V. Gratl,Marc Lemmens,Klaus F. X. Mayer,Hélène Bergès,Gerhard Adam,Hermann Buerstmayr +12 more
TL;DR: Fine mapping and sequencing revealed that the region of Fhb1 deviates from the Chinese Spring reference in DNA size and gene content, which explains the repressed recombination at the locus in the performed fine mapping.
Journal ArticleDOI
Quantitative trait loci-dependent analysis of a gene co-expression network associated with Fusarium head blight resistance in bread wheat ( Triticum aestivum L.)
Karl G. Kugler,Gerald Siegwart,Thomas Nussbaumer,Christian Ametz,Manuel Spannagl,Barbara Steiner,Marc Lemmens,Klaus F. X. Mayer,Hermann Buerstmayr,Wolfgang Schweiger +9 more
TL;DR: A combination of a network-driven approach and differential gene expression analysis identified genes and pathways associated with Fhb1 and Qfhs, which take prominent roles in the pathogen response.
