Verticillium wilt of olive (VWO) is caused by the vascular pathogen Verticillium dahliae. One of the best VWO management measures is the use of tolerant cultivars; however, our knowledge on VWO tolerance/resistance genetics is very limited. A transcriptomic analysis was conducted to (i) identify systemic defense responses induced/repressed in aerial tissues of the tolerant cultivar Frantoio upo...
Feeding activities of the tea green leafhopper, Empoasca vitis (Gothe) (Homoptera: Cicadellidae), on resistant and susceptible cultivars of tea plants (Camellia sinensis L.) were recorded and analyzed using the direct current electrical penetration graph (EPG) system. Six distinct EPG waveforms characterizing the feeding behavior of the tea green leafhopper, categorized as waveforms A, C, E, S,...
Line Yesevi-93 (cultivar Abidar) was first introduced to Dryland Agricultural Research Institute (DARI) through the International Winter Preliminary Barley Yield Trials (IWPBYT) in 1994. It was selected as one the most high yielding lines based on observational and statistical trails (Regional Barley Yield Trials) carried out in different locations during 1997-2000. The average yield of Abidar...
Pectobacterium carotovorum subsp. brasiliense is a newly identified member of the potato soft rot enterobacteriaceae. The pathogenesis of this pathogen is still poorly understood. In this study, an mCherry-P. carotovorum subsp. brasiliense-tagged strain was generated to study P. carotovorum subsp. brasiliense-potato plant interactions. Prior to use, the tagged strain was evaluated for in vitro ...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
To understand the response of potato to salt stress, antioxidant enzyme activities and ion content were analyzed for a sensitive and a tolerant cultivar. Nodal cuttings of the tolerant cultivar, Kennebec, and the sensitive cultivar, Concord, were exposed to media without or with 30, 60, 90 or 120 mmol/L NaCl for 4 weeks. On exposure to NaCl, the length and fresh and dry weight of both shoots an...
One of the main problems in vineyards of Iran is sensitivity of grape cultivars to winter cold. Considering the rich genetic diversity of grape cultivars in Iran vineyards and severe cold winter in 2007, this situation was used as a natural treatment in order to identify cold tolerance and assess damages in 21 Iranian grape varieties and 8 European grape varieties in a factorial experiment, bas...
drought tolerance of three own-rooted grape cultivars (rashe, ghezil uzum and red sultanina) was evaluated at four different levels of soil moisture contents (40, 60, 80 and 100% field capacity through a factorial experiment based on a randomized complete block design with three replications for a duration of 3 months. results revealed that, grape cultivars, levels of soil moisture and the inte...
This experiment was performed to study osmoregulators in sugar beet under salinity stress, and determine the best method for screening of tolerant and susceptible cultivars, in the greenhouse of Shahid Chamran University of Ahvaz during 2009-2010 growing season. Three sugar beet cultivars (BR1, Jolgeh & Rassoul) were grown under three salinity levels including control (Zero), 100 and 200 mM NaC...
reactions of 20 cucumber cultivars, tested to fusarium stem and root rot disease, have ranged from susceptible to tolerant. the most susceptible cultivars were 8-ayat, 32-pv, cb- 61688222, janette, nasco, negeen, nicoo 100, psr36-47112, rubah-l, rubah-s and sultan and tolerant cultivars were 120118, ayat, jakie, fd-c101, festival, khassib, psr 36-45007, sr36-45664 and storm. between these culti...
