Responses to Selection for Partial Resistance to Crown Rust in Oat

Crown rust, caused by the fungal pathogen, Puccinia coronata Corda var. avenae W.P. Fraser Ledingham, reduces kernel quality and grain yield in oat (Avena sativa L.). Partial resistance is considered to be a durable form of rust resistance. This study sought to evaluate the feasibility of simultaneously improving partial resistance to crown rust, grain yield, and seed weight in an oat populatio...

Mechanisms of oat (Avena sativa L.) acclimation to phosphate deficiency

Background Deficiency of available forms of phosphorus is common in most soils and causes reduction of crop plants growth and yield. Recently, model plants responses to phosphate (Pi) deficiency have been intensively studied. However, acclimation mechanisms of cereals like oat (Avena sativa L.), to low Pi stress remains not fully understood. Oat plants have been usually cultured on poor soils, ...

Sources and genetics of crown rust resistance in barley.

ABSTRACT Crown rust, caused by Puccinia coronata var. hordei, is a new disease threat to barley in the Great Plains region of the United States. Deployment of resistant cultivars is the only economically viable option for the control of this disease. Thus, the objective of this study was to investigate the sources and genetics of crown rust resistance in barley. A geographically diverse sample ...

Electrophoresis and Electrofocusing of Phytochrome from Etiolated Avena sativa L

R udolf Schendel and W olfhart Rüdiger Botanisches Institut der Universität München Z. Naturforsch. 44c, 12—18 (1989); received November 25, 1988 Microheterogeneity, Pest Sequence, Phytochrome Denaturation, Protein Conformation Phytochrome from etiolated oat seedlings (Avena sativa L.) was investigated by “native” gel electrophoresis and by isoelectric focusing. At pH 8 . 8 the Pfr form migrate...
