Infection of Brachypodium distachyon by formae speciales of Puccinia graminis: early infection events and host-pathogen incompatibility.

Autor: Melania Figueroa, Stephen Alderman, David F Garvin, William F Pfender

Publikováno v: PLoS ONE, Vol 8, Iss 2, p e56857 (2013)

Puccinia graminis causes stem rust, a serious disease of cereals and forage grasses. Important formae speciales of P. graminis and their typical hosts are P. graminis f. sp. tritici (Pg-tr) in wheat and barley, P. graminis f. sp. lolii (Pg-lo) in per

Evaluation of Postharvest Burning and Fungicides to Reduce the Polyetic Rate of Increase of Choke Disease in Orchardgrass Seed Production

Autor: W. F. Pfender, S. C. Alderman

Publikováno v: Plant disease. 87(4)

Epichloë typhina, causal agent of choke disease, is detrimental to orchardgrass seed production. The fungus grows systemically, persists indefinitely as an endophyte within the perennial host, and produces a stroma bearing conidia and ascospores at

Sensitivity of Disease Management Decision Aids to Temperature Input Errors Associated with Sampling Interval and Out-of-Canopy Sensor Placement

Autor: W. F. Pfender, David H. Gent, Walter F. Mahaffee

Publikováno v: Plant disease. 96(5)

Many plant disease epidemic models, and the disease management decision aids developed from them, are created based on temperature or other weather conditions measured in or above the crop canopy at intervals of 15 or 30 min. Disease management decis

A Latent Period Duration Model for Wheat Stem Rust

Autor: John F. Hernandez Nopsa, W. F. Pfender

Publikováno v: Plant Disease. 98:1358-1363

Wheat stem rust (WSR), caused by Puccinia graminis subsp. graminis Pers., is a highly destructive disease of wheat and several other small grains. The discovery of P. graminis subsp. graminis race Ug99, which overcomes previously effective resistance

The Use and Role of Predictive Systems in Disease Management

Autor: Neil McRoberts, W. F. Pfender, David H. Gent, Walter F. Mahaffee

Publikováno v: Annual Review of Phytopathology. 51:267-289

Disease predictive systems are intended to be management aids. With a few exceptions, these systems typically do not have direct sustained use by growers. Rather, their impact is mostly pedagogic and indirect, improving recommendations from farm advi

Pathotype-specific QTL for stem rust resistance in Lolium perenne

Autor: M. E. Slabaugh, W. F. Pfender

Publikováno v: Theoretical and Applied Genetics. 126:1213-1225

A genetic map populated with RAD and SSR markers was created from F1 progeny of a stem rust-susceptible and stem rust-resistant parent of perennial ryegrass (Lolium perenne). The map supplements a previous map of this population by having markers in
