In the framework of study on rust fungi of Fabaceae and based on the study of herbarium and newly collected specimens, six Uromyces species are recognized on Medicago spp. and Trifolium spp. from Iran. Among these species, U. fallens is recorded as new member for the Iranian rust flora. U. striatus is recorded as main causal agent of rust on lucerne (Medicago sativa) in Iran. Moreover, U. trifo...
Rust fungi are some of the most devastating pathogens of crop plants. They are obligate biotrophs, which extract nutrients only from living plant tissues and cannot grow apart from their hosts. Their lifestyle has slowed the dissection of molecular mechanisms underlying host invasion and avoidance or suppression of plant innate immunity. We sequenced the 101-Mb genome of Melampsora larici-popul...
Cronartium quercuum f. sp. fusiforme is the causative agent of fusiform rust disease of southern pines in the United States. This disease is characterized by the formation of woody branch and stem galls. Differential display was used to identify pine genes whose expression is altered by C. quercuum f. sp. fusiforme infection and to identify C. quercuum f. sp. fusiforme genes that are expressed ...
In the Republic of Tatarstan, due to favorable soil-climatic and market conditions, spring wheat production is developed, but grain yields are limited by a number unfavorable factors, one which spread fungal diseases. At same time, pressure pathogenic fungi makes it possible carry out fruitful breeding work in Tatarstan on resistance diseases, main activity Kazan Research Center RAS. The purpos...
Cool-season grasses are intensively cultivated for seed production in western Oregon, where stem rust is the most damaging disease on several species, including perennial ryegrass (Lolium perenne), annual ryegrass (L. multiflorum), and tall fescue (Festuca arundinacea). Stem rust also occurs on seed crops of orchard grass (Dactylis glomerata) and red fescue (F. rubra) in the region. The causal ...
The biotrophic rust fungi Puccinia hordei and Puccinia striiformis are important barley pathogens with the potential to cause high yield losses through an epidemic spread. The identification of QTL conferring resistance to these pathogens is the basis for targeted breeding approaches aiming to improve stripe rust and leaf rust resistance of modern cultivars. Exploiting the allelic richness of w...
