P. atlantica subsp. Kurdica, with the local name of Baneh, is a wild medicinal plant which grows in Kurdistan, Iran.  The identification of resistance gene analogs holds great promise for the development of resistant cultivars. A PCR approach with degenerate primers designed according to conserved NBS-LRR (nucleotide binding site-leucine rich repeat) regions of known disease-resistance (R) gene...

some thoughts and events are of a prominent position in human life as if they lead human to insistence and repetition by becoming a part of his concerns and at last they represent themselves as an individual and permanent feature in his conscious and unconscious. but permanent repetition of the mentioned imagery represents a subject  of whose reality there is no information available under norm...

this work presents a hybrid method for motif discovery in dna sequences. the proposed method called spso-lk, borrows the concept of chebyshev polynomials and uses the stochastic local search to improve the performance of the basic pso algorithm as a motif finder. the chebyshev polynomial concept encourages us to use a linear combination of previously discovered velocities beyond that proposed b...

in a structural analysis, the “rebellion & decline” theme creates a narrative structure in which eleven stories of shāhnāmeh – equal to 3.18 per cent of the whole epic – are included, which makes it the tenth largest sequence of the shāhnāmeh. this narrative structure (sequence) consists of initial tranquillity, the king’s rebellion, his decline, and ultimate tranquillity. the epical theme of r...

quorum sensing controls the luminescence of vibrio fischeri through the transcriptional activator luxr and the specific autoinducer signal produced by luxi. amino acid sequences of these two genes were analyzed using bioinformatics tools. luxi consists of 193 amino acids and appears to contain five α-helices and six ß-sheets when analyzed by sspro8. luxi belongs to the autoinducer synthetase fa...

in every field, typology leads to a better, more complete and more precise knowledge. in spite of the importance and extent of traditional persian stories, there is as yet no complete classification of these stories. most of the present classifications are imprecise, mixing the different kinds of stories. this paper merely deals with an analysis, criticism, morphology and typology of persian tr...

aim : the aim of this study is to evaluate the polymorphism in bax gene and its association with some clinical pathology traits in gastric cancer.   background : gastric cancer is considered as the fourth most common cancer in the north and northwest of iran. bcl2 family has a key role in regulation of apoptosis, and any changes in the expression of bcl2 lead to cancer. patients and methods : b...

Peroxidase enzymes are vastly applicable in industry and diagnosiss. Recently, we introduced a new kind of peroxidase gene from Lepidium draba (LDP). According to protein multiple sequence alignment results, LDP had 93% similarity and 88.96% identity with horseradish peroxidase C1A (HRP C1A). In the current study we employed in silico tools to determine, to which group of peroxidase enzymes LDP...
