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...
genus polymyxa, belongs to plasmodiophoromycota phyllum and protozoa kingdom. this fungus is a obligate endoparasite in the root cells of vascular plants. since the two species of this genus, p. graminis and p. betae are both known to carry destructive viral agents to sugar beet and poaceae. for studying the distribution of infected fields with p. betae in razavi and northern khorasan provinces...
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...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Background & Objectives: In recent decades, rate of infections caused by opportunistic fungi, such as Candida albicans, has increased dramatically. Treatment of fungal diseases is associated with limitations such as rare and expensive antifungal drugs and their side effects, drug resistance and reduced susceptibility of fungi to drugs. Therefore, researchers have been concerned with finding new...
In survey of infected samples to downy mildew of broadbean, Chenopodium murale and Rumex chalpensis using Olympus microscope (BH2) and valid keys and recently published papers, two species were identified (Choi et al. 2009, Ershad 2009, Telle & Thines 2012).
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
Indian citrus ringspot virus (ICRSV) is known to cause serious disease problem in Kinnow (Citrus nobilis Lour C. deliciosa Tenora). This paper reports the various methods viz. Bioassay, ELISA and RT-PCR for indexing of ICRSV. Bioassay was performed on Chenopodium amaranticolor, Cucumis sativus, Nicotiana glutinosa, N. tabacum, Petunia hybrida and Phaseolus vulgaris. However necrotic local lesio...
