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...
Different species of Streptomyces are common in most types of soil. Some certain species are plant pathogenic especially on potato. This study was conducted to evaluate genetic diversity among some local Streptomyces spp. strains isolated from soil and infected tubers in potato farms in northwest of Iran. Repetitive DNA elements (BOX, ERIC and REP) as genetic markers were used for diversity stu...
DNA sequence data contains a wealth of biologically useful information. Recent innovations in DNA sequencing technology have greatly increased our capacity to determine massive amounts of nucleotide sequences. These sequences can be used to specify the characteristics of different regions, interpret the evolutionary relationships between categorized groups, likelihood of performing multiple com...
genetic relationships among three yarrow species based on phenotypic traits and peroxidase profiling
fifteen yarrow populations from different species achillea millefolium l., a. biebersteinii l. and a. nobilis, from different geographical areas of iran were studied using 24 morphological traits and peroxidase profiles. comparison of mean values of different phenotypic traits show a. millefolium and a. biebersteinii l. had higher plant height and crown diameter; however, a. nobilis had higher ...
In breeding programs, it is necessary having knowledge of the relatedness and genetic diversity in germplasm pools. The spread of cultivated regions and the high levels of production indicates citrus importance in the global economy. Therefore, 110 citrus genotypes were evaluated using 12 ISSR markers. Overall, 154 polymorphic bands were scored with an average of 12.8 alleles per primer. The po...
Nuclear simple sequence repeats (nSSRs), together with 16 different enzyme loci, were used to analyzegenetic diversity and differentiation among beech (Fagus orientalis Lipsky) populations along two altitudinalgradients in Hyrcanian forests of Iran. Both enzymes and nSSR analyses revealed a high level ofgenetic diversity in natural populations of F. orientalis. The genetic div...
Oxynoemacheilu sangorae is an endemic freshwater fish of Iran. In the present study, six microsatellite markers were used to investigate population structure of stone loach (Oxynoemacheilusangorae) in gheshlagh (Kurdistan), Sefidbarg and Gamasiab (Kermanshah) rivers. All of the applied loci showed polymorphism. The average numbers of allele and observed heterozygosity were 14.33 and 0.82 respec...
The genetic diversity of a large number of pistachio genotypes grown in Iran is not exactly known. Most of the studies on genetic diversity of Iranian pistachio varieties are based on morphological characteristics or isozyme markers. In the present study, the genetic diversity of selected pistachio cultivars along with some wild species were evaluated by Amplified Fragment Length Polymorphism (...
in order to investigate genetic diversity of two flax species, 50 genotypes were evaluated. the results showed that there was significant difference between two subspecies and also among different regions in subspecies for some seed yield components and us subspecies was superior than md for number of capsules/plant but md subspecies had more 1000 seed weight. genetic variation in each region w...
