شناسایی و انتقال ژن از خویشاوندان وحشی به گونه های زراعی یکی از روش های اصلاح گیاهان برای ایجاد مقاومت به بیماری ها و آفات بشمار می رود. این مطالعه با هدف بررسی امکان تلاقی پذیری و واکنش به pythium ultimum در گلرنگ زراعی و دو خویشاوند دیگر آن انجام شد. برای بررسی واکنش به بیمارگر از هشت ژنوتیپ متعلق به گونه زراعی، دو توده از گونه وحشی c. oxyacanthus از تهران و اصفهان و یک توده از گونه وحشی c. l...

The kingdom Stramenopile includes diatoms, brown algae, and oomycetes. Plant pathogenic oomycetes, including Phytophthora, Pythium and downy mildew species, cause devastating diseases on a wide range of host species and have a significant impact on agriculture. Here, we report comparative analyses on the genomes of thirteen straminipilous species, including eleven plant pathogenic oomycetes, to...

Oomycetes form a deep lineage of eukaryotic organisms that includes a large number of plant pathogens which threaten natural and managed ecosystems. We undertook a survey to query the community for their ranking of plant-pathogenic oomycete species based on scientific and economic importance. In total, we received 263 votes from 62 scientists in 15 countries for a total of 33 species. The Top 1...

Extracts from the plants Plantago lanceolata and P. rugelii were evaluated for toxicity to the root-knot nematode Meloidogyne incognita, the beneficial microbes Enterobacter cloacae, Pseudomonas fluorescens and Trichoderma virens, and the plant-pathogenic fungi Fusarium oxysporum f. sp. gladioli, Phytophthora capsici, Pythium ultimum, and Rhizoctonia solani. Wild plants were collected, roots we...
