this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
The thermal inactivation point (TIP) of SCSMV was determined by heating the infected plant sap for 10 min at 50oC, 55oC, 60oC, and 65oC. The sap was inoculated mechanically on indicator plant Dactylactonium aegypticum. The virus was detected by a reverse transcription polymerase chain reaction (RT-PCR) using specific primer to amplify a part of the coat protein (CP) gene. The SCSMV was detected...
Background: Groundnut bud necrosis virus (GBNV) (Tospovirus genus, Bunyaviridae family) infects the major crops of solanaceae, leguminosae and cucurbitaceae in India. Temperature is an important factor which influences the plant growth and development under diseased conditions.Objective: In the present study, we evaluated the effect of four different temp...
mixed infection of plants with more than one virus results in different types of interactions. interaction between two recently identified lettuce infecting viruses in iran, lettuce x potexvirus (levx) and rubus chlorotic mottle sobemovirus (rucmv), was studied on co-infected chenopodium murale and chenopodium quinoa plants. plants were mechanically inoculated with either levx, rucmv or both. c...
during the summer of 2004, a survey was conducted to determine the incidence and distribution of beet necrotic yellow vein virus (bnyvv) and its vector (polymyxa betae keskin) in marvdasht, fars province of iran. a total of 353 root samples were collected randomly as well as 124 samples from plants showing rhizomania- associated symptoms. the presence of bnyvv in the samples were tested by tr...
