Journal ArticleDOI
Identity, regulation, and activity of inducible diterpenoid phytoalexins in maize
Eric A. Schmelz,Fatma Kaplan,Alisa Huffaker,Nicole J. Dafoe,Martha M. Vaughan,Xinzhi Ni,James R. Rocca,Hans T. Alborn,Peter E. A. Teal +8 more
TL;DR: The presence of diterpenoid defenses in maize is established and enables a more detailed analysis of their biosynthetic pathways, regulation, and crop defense function.
Journal ArticleDOI
Novel Acidic Sesquiterpenoids Constitute a Dominant Class of Pathogen-Induced Phytoalexins in Maize
Alisa Huffaker,Fatma Kaplan,Martha M. Vaughan,Nicole J. Dafoe,Xinzhi Ni,James R. Rocca,Hans T. Alborn,Peter E. A. Teal,Eric A. Schmelz +8 more
TL;DR: Zealexins exhibit antifungal activity against numerous phytopathogenic fungi at physiologically relevant concentrations and indicate an important cooperative role of terpenoid phytoalexin in maize biochemical defense.
Journal ArticleDOI
Plant elicitor peptides are conserved signals regulating direct and indirect antiherbivore defense
Alisa Huffaker,Gregory Pearce,Nathalie Veyrat,Matthias Erb,Ted C. J. Turlings,Ryan C. Sartor,Zhouxin Shen,Steven P. Briggs,Martha M. Vaughan,Hans T. Alborn,Peter E. A. Teal,Eric A. Schmelz +11 more
TL;DR: Peps are conserved signals across diverse plant families regulating antiherbivore defenses and are likely to be the missing functional homologs of systemin outside of the Solanaceae.
Journal ArticleDOI
Evolution of structural diversity of trichothecenes, a family of toxins produced by plant pathogenic and entomopathogenic fungi.
Robert H. Proctor,Susan P. McCormick,Hye-Seon Kim,Rosa E. Cardoza,April M. Stanley,Laura Lindo,Amy C. Kelly,Daren W. Brown,Theresa Lee,Martha M. Vaughan,Nancy J. Alexander,Mark Busman,Santiago Gutiérrez +12 more
TL;DR: The results indicate that structural diversity has resulted from gain, loss, and functional changes of trichothecene biosynthetic (TRI) genes and the presence of some substituents has arisen independently in different fungi by gain of different genes with the same function.
Journal ArticleDOI
Accumulation of terpenoid phytoalexins in maize roots is associated with drought tolerance.
Martha M. Vaughan,Shawn A. Christensen,Eric A. Schmelz,Alisa Huffaker,Heather J. McAuslane,Hans T. Alborn,Maritza Romero,Leon Hartwell Allen,Peter E. A. Teal +8 more
TL;DR: It is found that the quantity of drought-induced phytoalexins is positively correlated with the root-to-shoot ratio of different maize varieties, and it is demonstrated that mutant an2 plants deficient in kauralexin production are more sensitive to drought.
