FgABC1 (FGSG_04580) is predicted to encode a pleiotropic drug resistance class ABC transporter in Fusarium graminearum, a globally important pathogen of wheat. Deletion mutants of FgABC1 showed reduced virulence towards wheat in crown and root infection assays but were unaltered in infectivity on barley. Expression of FgABC1 during head blight and crown rot disease increases during the necrotro...
Phytophtora crown- and root- rot is one of the important soil-borne diseases of strawberry grown in hydroponic culture. Plant roots affected by root and crown rot show yellowish and decline symptoms and the plant perishes and dies gradually. To identify the factor responsible for strawberry crown rot, some samples were taken from infected plants. The samples were washed with tap water for 1-2 h...

In recent years, oak trees in the Zagros forests have suffered a lot of fatalities for unclear reasons. Determining the rate and severity of forest crown density changes is important for the investigation and management of these forests. This research was carried out with the aim of determining the amount of crown cover changes in the forest area of Dashtebarm in Fars province under the influen...
in order to study the mode of genetic control and heritability of morphological characteristics important for the improvement of root weight, sugar yield and white sugar yield in tropical beet, griffing's diallel cross method along with the biplot display of diallel data were applied. nine sugar beet lines including 7112-36, 7173, 474, 452, 261, 436-104, sb-firoz, rr607 and 436 were crosse...
root and crown rot of sugar beet caused by rhizoctonia solani ag2-2 is a destructive disease in the main sugar beet growing areas. use of resistant cultivars is the most effective and environmentally safe way to control the disease. in order to find resistant genotypes, 70 sugar beet lines together with resistant and susceptible checks were evaluated against a highly virulent isolate of r.solan...
resistance of 16 sugar beet cultivars to cercospora leaf spot was evaluated in ghaemshahr region. the experiment was conducted in a complete block design with six replications and disease severity of cultivars was measured two times. as a winter crop the root yield of cultivars and their disease severity compared under natural cercospora infection in dezfoul area in a complete block design with...

Background and purpose: Stachys inflata Benth from Lamiaceae family, as one of the most important medicinal species widely used among people and industries, and the aerial parts of this plant are used as an anti-inflammatory and pulmonary infection medicine. This species is widely distributed in the world and especially in different parts of the country. Considering the significant distribution...
Six different strains of crown gall bacteria were tested to determine whether the commonly used biocontrol strain, K-84, would present them from infecting the paradox hybrid. Previous research showed that K-84 was highly effective in preventing crown gall infections of English root stock. There was considerable variability among the six strains in ability to cause disease. One of the strains di...
