nowadays, a lot of frost damage is inflicted upon vineyards because of changing weather conditions as well as introducing new of cultivars and genotypes from different geographical regions. on the other hand, the prevalence of a wide variety of grapes in iran, the provides possibility of selection of superior and cold tolerant varieties (or single plants) which is proposed a strong hypothetical...

In response to cold stress, Drosophila Melanogaster increase their expression of Frost, a candidate gene involved in cold response. The direct role of Frost in cold tolerance is yet to be determined, and its importance for survival in cold environments has been questioned. In this study, I attempt to better understand the molecular machinery of Frost by selecting for its protein in fly lysate k...

Plants respond to cold stress by modulating biochemical pathways and array of molecular events. Plant morphology is also affected by the onset of cold conditions culminating at repression in growth as well as yield reduction. As a preventive measure, cascades of complex signal transduction pathways are employed that permit plants to endure freezing or chilling periods. The signaling pathways an...

Plasma membrane protein 3 (PMP3), a class of small hydrophobic polypeptides with high sequence similarity, is responsible for salt, drought, cold, and abscisic acid. These small hydrophobic ploypeptides play important roles in maintenance of ion homeostasis. In this study, eight ZmPMP3 genes were cloned from maize and responsive to salt, drought, cold and abscisic acid. The eight ZmPMP3s were m...

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...

introduction: calcium/calmodulin-dependent protein kinase ii (camkii) is highly expressed in the hippocampus, which has a pivotal role in reward-related memories and morphine dependence. methods: in the present study, morphine tolerance was induced in male wistar rats by 7 days repeated morphine injections once daily, and then gene expression profile of α-isoform of camkii (camkiiα) in the hipp...

Plant growth and productivity are greatly affected by environmental stresses such as drought, high salinity, and low temperature. Expression of a variety of genes is induced by these stresses in various plants. The products of these genes function not only in stress tolerance but also in stress response. In the signal transduction network from perception of stress signals to stress-responsive g...

the purpose of this study was to investigate the effectiveness of emotional regulation training group therapy, based on dialectical behavioral therapy (dbt) and cognitive therapy, on improving emotional regulation and distress tolerance skills and relapse prevention in addicts.in a quasiexperimental study, 39 patients with the diagnosis of opioid dependence based on dsm-iv criteria were randoml...
