Herbicide resistant crops are commercially advantageous for efficient field productivity by enabling use of nonselective herbicides for weed management. Herbicide resistant trees could be used to improve productivity and reduce the costs of forest management through to the first and second years post tree establishment. We describe the introduction of the phosphinothricin acetyltransferase (bar...
A total of forty-three isolates of Ascochyta rabiei obtained from infected seeds and plants of chickpea from different areas of Kermanshah, Lorestan, Hamadan, Kordestan, and East and West Azarbaijan provinces were studied during the period 1996-1999. A rapid and simple method was developed for pathogenicity test in CDA (chickpea seed meal dextrose agar) medium. CDA medium was inoculated with di...
Mesembryanthemum crystallinum L. plants shift the mode of carbon assimilation from C(3) to Crassulacean acid metabolism when stressed by high salinity. A prerequisite for Crassulacean acid metabolism induction is the synthesis of phosphoenolpyruvate carboxylase (PEPCase). A moderate increase in the abundance of PEPCase transcripts and activity is observed in 7-week-old, well-watered plants. Thi...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
The effect of experimental Newcastle disease virus (NDV) infection on some aspects relating to endocrinology calcium metabolism, which affects eggshell quality and production, was studied. Twenty 22-week-old ISA brown layers vaccinated against (ND) were allocated infected uninfected groups 10 chickens each. in the group inoculated intranasally with 0.1 ml NDV (Kudu 113 strain). Blood samples co...
Some of the factors that influence canker development in American sycamores inoculated with Botryodiplodia theobromae conidia were determined. A combination of B. theobromae culture filtrates and conidia resulted in 100% canker production when Iiitroduced into stem wounds; however. a combination of Cephalosporium diospyri culture filtrates and B. theobromae conidia resulted in no canker product...
Rabbits were inseminated artificially and inoculated 1 week later with rubella virus. The attenuated vaccine strain HPV-77 or strain 67-1127 which had been through 12 cell culture passages was used. Half of the rabbits in each group had been inoculated 1 month prior to insemination with the corresponding strain. Evidence of infection induced by either strain was obtained by immunofluorescence i...

fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
