Abiotic stresses such as salinity influence agricultural production. Plants generally respond to stimulus conditions in a complex manner involving many genes and proteins. In the evolution process, halophyte plant Aeluropus littoralis has been proven to have abiotic stress-tolerance capacity. A. littoralis is a salt-resistant halophyte providing a wealthy genetic resource for developing salinit...

Three new species of Labena Cresson (Ichneumonidae, Labeninae); L. littoralis sp. nov., L. tekalina sp. nov. and L. madoricola sp. nov. are described and illustrated. Material was collected with Malaise traps in 2008 and 2009 in the Biosphere Reserve Ria Lagartos (Mexico). Diagnostic characters to distinguish them from all other New World species of the genus are provided. In addition, the trop...

abstract- annual medicago species (medicago spp.) are native to the mediterranean region and widely used in fields and pastures in iran. there are several methods of sowing annual medicago species, each with different effects on the performance. however, there is currently no sufficient information about the appropriate methods for sowing medicago species. in order to evaluate methods of sowing...

this study was carried out to investigation the possibility of using triadimefon (trd) in order to decrease the adverse effects of salt stress on medicago plant. triadimefon is a member of triazol compounds which enhances stress tolerance through physiological processes. two cultivars of medicago sitiva including hamedani and yazdi were used in this study. plants were treated with 1, 2 and 4 mg...

During plaque purification of Spodoptera littoralis nucleopolyhedrovirus in S. littoralis Sl52 cell culture, a deletion mutant virus was isolated. Analysis of the biological properties of this mutant virus revealed an absence of per os infectivity of the occluded virus. Infectivity by injection of the non-occluded (budded) virus is not different between the wild-type and the deleted virus. Rest...
