BACKGROUND AND AIMS The study of rapid evolution in invasive species has highlighted the fundamental role played by founder events, emergence of genetic novelties through recombination and rapid response to new selective pressures. However, whether rapid adaptation of introduced species can be driven by punctual changes in genome organization has received little attention. In plants, variation ...

Purpose of the study: to study effect oil pollution on morphological parameters cereal grasses: canary grass, timothy grass and meadow fescue. Tasks: assessment impact soils seed germination, growth development studied species by parameters; analysis variability indicators. Oil-contaminated high-moor peat was used as a substrate. Objects research: seeds Phleum pratense L, 1753, fescue Festuca p...

Industrial crop cultivation on marginal agricultural land limits indirect land-use change effects that pose a threat to food security. This review compiles results from 91 published crop-specific field trial datasets spanning 12 relevant industrial crops and discusses their suitability for unfavorable soil types (USTs). It was shown the perennial species Miscanthus (Miscanthus Andersson) reed c...

citrus blast is one of the important diseases of citrus in north of iran. the disease causes considerable damage during and immediately after the cold seasons. the causal agents have epiphytic survival on diverse weeds during spring and summer. during 2009-2010, samples were collected from several candidate weed plants including: poa annua, phalaris canariensis, sorghum halepense, cynodon dacty...

The purpose of this study was to identify new species of Parastagonospora in association with poaceous plants in Iran. Symptomatic leaves and ears were collected from different poaceous species in the field from provinces including Fars, Khuzestan and Kohgiluyeh and Boyerahmad. In the present research, 12 isolates based on morphological characteristics and sequencing of LSU and ITS-rDN...
