Five accessions of Aegilops speltoides and 67 European wheat cultivars (winter and spring) originating from the Czech Republic, Germany, Poland, Russia, Slovakia, United Kingdom, and 4 non-European wheat cultivars from Brazil and the USA were examined with molecular Sequence Tagged Site (STS) markers for resistance genes to powdery mildew: Pm 1, Pm 2, Pm 3 and Pm 13. All markers gave clear, rep...
Background Puccinia psidii causes rust disease on many host species in the Myrtaceae [1]. First reported in 1884 on guava in Southern Brazil [2], the rust has since been detected on several myrtaceous in South America, Central America, Caribbean, Mexico, USA: in Florida, California, and Hawaii. More recently, P. psidii was reported in Japan infecting M. polymorpha[3]. Of special note is that a ...
در این بررسی، تاکسونومی puccinia coronata در ایران با توجه به خصوصیات مورفولوژیک هاگ های مراحل مختلف مورد مطالعه قرار گرفت و چهار واریته درون گونه مذکور تعیین شد که عبارتند از: p. coronata var. coronata, p. coronata var. avenae, p. coronata var. hordei, p. coronata var. golestanica var. nov. در بین آرایه های تعیین نام شده، واریته golestanica برای دنیا و واریته های avenae و hordei برای فلور ز...
Antigens and antisera from in vitro cultures of Puccinia melanocephala Sydow, uredospores collected from the field and sugar cane varieties were obtained. Cross-reactions were detected between the fungi and plants by counterimmunoelectrophoresis, immunoelectrophoresis and indirect ELISA. The last technique detected more antigenic relationships with the susceptible plants. This result may be use...

A new model for grass functional genomics is described based on Brachypodium distachyon, which in the evolution of the Pooideae diverged just prior to the clade of "core pooid" genera that contain the majority of important temperate cereals and forage grasses. Diploid ecotypes of B. distachyon (2n = 10) have five easily distinguishable chromosomes that display high levels of chiasma formation a...
Wheat industry is an important constituent of Northern China’s overall agricultural economy. Proper disease detection using computer vision and pattern recognition has being investigated to minimize the loss, and finally achieve intelligent healthy farming. This paper proposes a new strategy of Multi-Classifier System based on SVM (support vector machine) for pattern recognition of wheat leaf d...
Three members of the Puccinia genus, Pucciniatriticina (Pt), Pstriiformis f.sp. tritici (Pst), and Pgraminis f.sp. tritici (Pgt), cause the most common and often most significant foliar diseases of wheat. While similar in biology and life cycle, each species is uniquely adapted and specialized. The genomes of Pt and Pst were sequenced and compared to that of Pgt to identify common and distingui...
