Resistance of various biotypes of Canary grass (phalaris. Spp) to acetyl-CoA carboxylase-inhibiting herbicides.
Little seed canary grass (Phalaris minor L.) is a major weed in wheat fields in some parts of Iran. To evaluate the efficacy of molecular and greenhouse methods in detecting the resistance of 49 biotypes of canary grass(Phalaris. Spp) to acetyl-CoA carboxylase-inhibiting herbicides, two methods including whole plant screening and PCR-based molecular methods were applied. Results showed that the...
متن کاملProduction of peptide ergot alkaloids in submerged culture by three isolates of Claviceps purpurea.
Three strains of Claviceps purpurea (Fr.) Tul., isolated from sclerotia grown on rye, produce under submerged conditions ergocryptine and ergotamine, ergocornine and ergosine, and ergocristine, respectively. All of the strains either lacked the ability to produce conidia or formed them sparingly, but they accumulated large quantities of lipids and sterols. The fermentations are typically divide...
متن کاملAssociation of insects and ergot (Claviceps purpurea) in Kentucky bluegrass seed production fields.
Insects in Kentucky bluegrass seed production fields in Oregon, Idaho, and Washington were sampled just before harvest and their association with ergot conidia of Claviceps purpurea Fr. (Tul.) was evaluated during 1996-1998. A diversity of insects was observed at all three locations. The most abundant beneficial insects collected with sweep nets were Nysium spp., Nabis spp., ichneumonid wasps, ...
متن کاملLong-Term Production of Ergot Peptides by Immobilized Claviceps purpurea in Semicontinuous and Continuous Culture.
The semicontinuous and continuous production of pharmaceutically useful ergot peptides with immobilized Claviceps purpurea could be demonstrated. A key aspect was the presence of high concentrations of CaCl(2) (96.9 mM) to give marked prolongation of the productive phase, and cultivation in a bubble column reactor became possible. Restriction of the phosphate supply avoided an otherwise problem...
متن کاملThe history of ergot of rye (Claviceps purpurea) III: 1940-80.
The period 1940-80 in the history of ergot was dominated by two investigators, Arthur Stoll and Albert Hofmann. There was great excitement when their group isolated from ergot preparations the powerful psychotropic agent lysergic acid diethylamide (LSD). It was thought that this substance would help to find the cause of schizophrenia and other psychotic disorders, but it would prove to be a gre...
