in the present study resistance of some elite lines of wheat at seedling stage were evaluated in cereal rusts greenhouse at seed and plant improvement institute in karaj and at adult plant stage in ahvaz under artificial inoculation with an isolate of leaf rust from ahvaz. for seedling resistance, different components of resistance were measured. the results showed that lines m-85-1, m-86-1 and...

The conventional histologic grading of colorectal cancer (CRC) is less suited for resected rectal cancer following neoadjuvant chemoradiation. Enumeration of poorly differentiated clusters (PDC) is a recently proposed histologic grading scheme. We aimed to apply PDC grading to treated rectal cancer and to test the prognostic significance of this novel approach. Archived hematoxylin and eosin sl...

The effect of 5-azacytidine (5-azaCR) on head regeneration and budding in hydra are reported. Hydra attenuata were exposed to various doses of 5-azaCR for 48 h and then decapitated and cultured. Head regeneration and bud formation were observed for 12 days after decapitation. Untreated control hydra regenerated heads within 7 to 8 days of decapitation with a budding index of 0.2. Buds invariabl...

in order to study the effect of rootstock, scion and some methods of grafting and budding to achieve the best methods of grafting in pomegranate, split factorial experiment was conducted in a completely randomized design in march 2013 in greenhouse at the agricultural college of vali-e-asr university of rafsanjan. factors included rootstock, scion, and methods of grafting and time of grafting. ...

The stage-specific activation of cyclin-dependent kinases controls the order and timing of cell-cycle transitions. Recent studies offer insight into the mechanism of cell-cycle-regulated transcription of the mitotic cyclins of budding yeast.

The relationship between the transition to budding and flowering in Artemisia annua and the production of the antimalarial sesquiterpene, artemisinin (AN), the dynamics of artemisinic metabolite changes, AN-related transcriptional changes, and plant and trichome developmental changes were measured. Maximum production of AN occurs during full flower stage within floral tissues, but that changes ...

The GagPol protein of HIV-1 harbors viral enzymes, such as protease (PR), reverse transcriptase, and integrase, that are all crucial for virion infectivity. Previous studies have suggested that expression of GagPol alone does not produce viral particles and that the budding defect is caused by the presence of the Pol region. However, it has remained unknown why GagPol fails to produce viral par...

salinity stress is one of the most important environmental constraints that have been limited agricultural production in iran. therefore, introducing suitable cultivars having desirable yield under salinity stress will lead to increase of production efficiency. in order to study the response of spring safflower cultivars to salinity, an experiment was carried out at the experimental station of ...
