anthracnose caused by colletotrichum gloeosporioides s. l. is one of the most important diseases of citrus in northern iran. to study the genetic structure of c. gloeosporioides s. l. from citrusspp., infected samples were collected from three citrus cultivating regions of northern iran, during the summer of 2009. fifty one monoconidial isolates were used as the objective of rep- and box-pcr fi...

Iris belongs toIridaceae family and it is monocotyledon. Iris is one of the important ornamental and medicinal plants. 34 iris genotypes (14 species) collected from different provinces of Iran were planted at National Institute of Ornamental Plants (NIOP) Iran. All of the species evaluated for 15 quantitative traits and 30 qualitative traits. Results showed that the highest positive correlation...

dermatophytes are a group of keratinophilic fungi capable of invading keratinized tissues (skin, hair and nails). they cause dermatophytosis (commonly known as tinea or ring worm) in human and animals. in this report, dna similarities and genomic linkage of 40 dermatophytes strains was obtained from different universities, were studied by random amplified polymorphic dna (rapd–pcr) using 11 ran...

Sixty isolates of Pythium aphanidermatum as the causal agent of sugar beet root rot were selected on the basis of their geographical origins, morphological and genetic diversity studies. Pathogenicity test using the Kruskal-Wallis analysis showed significant differences between the pathogenic potential of isolates. Based on the growth rate, isolates were categorized in two groups with low and h...

having knowledge about genetic relationships among accessions is necessary for developing breeding strategies to produce improved cultivars. in present study, genetic diversity and inter-relationship among 29 genotypes of citrus were comparatively analyzed using morphological and rapd markers. significant variability was observed among citrus genotypes for 61 quantitative and qualitative morpho...

Since identical twins occur as a result of the division of one egg, they have the same genetic structure. Therefore, their phenotypes and sex are also always the same. However, due to the effect of environmental factors, some of the characteristics of twins living in different regions appear to develop differently. In our case of 17-year-old maternal twins, we emphasized that nasal pathologies ...
