Methanol extracts from 27 medicinal plant species were tested at concentrations of 0.5, 1 and 2 mg/mL for their in vivo fungicidal activities against six phytopathogenic fungi. Their efficacy varied with plant pathogen, tissue sampled and plant species. Very strong fungicidal activity was produced by extracts of Boswellia carterii, Saussurea lappa, Glycyrrhiza uralensis, Piper nigrum, Rheum cor...

cDNA microarrays of Blumeria graminis f sp hordei transcript profiles during the asexual development cycle reveal the dynamics of global gene expression as the fungus germinates, penetrates, feeds on its host, and produces masses of conidia for dispersal. The expression profiles of genes encoding enzymes involved in primary metabolism show that there is a striking degree of coordinate regulatio...

Effective breeding work to create disease-resistant wheat varieties provides for regional, retrospective studies determine effective sources of resistance. One the most harmful and globally significant diseases is powdery mildew. In conditions Tatarstan, located in Volga economic region Russia, mass development mildew on spring common noted annually, regardless prevailing weather conditions. Th...

Race TTKSK (or Ug99) of Puccinia graminis f. sp. tritici possesses virulence to several stem rust resistance genes commonly present in wheat cultivars grown worldwide. New variants detected in the race TTKSK lineage further broadened the virulence spectrum. The identification of sources of genetic resistance to race TTKSK and its relatives is necessary to enable the development and deployment o...
