Habit and Habitat of Puccinia Graminis 2. Symptoms of Puccinia Graminis 3. Vegetative Structure 4. P. graminis is an obligate parasite, polymorphic, macro cyclic and heteroecious rust (Figs. 11, 12). It effects wide range of hosts. common barberry, Berberis vulgaris, and Puccinia graminis, the cause of stem rust, a destructive disease of small grains. As the alternate host of P. graminis, the barberry is the. Rust Fungi Forming Aecia on Berberis spp Berberis and related genera to Puccinia graminis. Tech. There appears to be little polymorphism for resistance/susceptibility in Berberis species.

Berberine (30), (Figure ) a protoberberine is an isoquinoline alkaloid extracted from several plants of the genus Berberis such as Berberis aquifolium, Berberis vulgaris, Berberis aristata (Berberidaceae) and other genera including Coptis chinensis, Hydrastis canadensis, Xanthorhiza simplicissima (Ranunculaceae), Phellodendron amurense (Rutaceae), Tinospora cordifolia (Menispermaceae. Genotypic variation of Puccinia graminis infecting barberry and grasses Karolina Jörgensen Supervisor: Dr. Anna Berlin, Swedish University of Agricultural Sciences, Department of Forest Mycology and Plant Pathology Assistant Supervisor: Professor Jonathan Yuen, Swedish University of Agricultural Sciences, Department of Forest Mycology and Plant Pathology. The wheat rust (Puccinia graminis) can severely reduce the yield of wheat, oat, and barley crops. Once common barberry was removed from oat production areas of Pennsylvania and wheat production areas of Virginia, crop yields increased by an average of % and 68%, respectively [ 12 ]. Berberis (Barberry, Pepperidge bush, Pepperidge-bushis) is a genus of about species of deciduous and evergreen shrubs from 1–5 m tall with thorny shoots, native to the temperate and subtropical regions of Europe, Asia, Africa, North America and South are closely related to the genus Mahonia, which is included within Berberis by some : Berberidaceae.

Berberis spp. serve as the alternate hosts to two important rust pathogens of small grains and grasses, Puccinia graminis and P. striiformis. Barberry erad-ication has been practiced for centuries as a means to control stem rust. Diverse virulence variations have been observed in populations of P. graminis f. sp.

The common barberry and several other Berberis spp. serve as the alternate hosts to two important rust pathogens of small grains and grasses, Puccinia graminis and P. ry eradication has been practiced for centuries as a means to control stem rust. Diverse virulence variations have been observed in populations of P. graminis f. sp. tritici that were associated Cited by: Szabo, ). In the study of 27 rust species of the genera Puccinia, Uromyces, Tranzschelia, Frommea (Phragmidium), and Melampsora the optimal temperature for teliospore germination was determined (Anikster, ). It varied between 16 and 18°C with the limits between 12 and 25°C (Anikster, ).
