Cumin (Cuminum cyminum L.) is one of the most important cultivable medicinal plants in Iran and today, it is the second most popular spice in the world after black pepper. It is essential to know the relationships between yield and its components in cumin breeding programs. Therefore, different multivariate statistical analysis was performed on plant characters in cumin to determine th...

Induced defenses may evolve in natural plant populations where heritable variation in inducibility affects plant fitness. Although this has not been documented for any plant – parasite system, genetic variation in induction has been recently reported for several plant-parasite systems. Correlations between induction and fitness in variable parasite environments suggest that inducibility may ind...

The main objective for plant breeding is to increase genetic diversity. Mutation induction is a method to increase genetic diversity associated with selection, recombination, or a combination of these approaches in plant breeding. The present research was aimed to compare efficacy of different doses of Gamma rays (150, 200, 250, 300 and 350 Gy and zero dose control) on the sesame morphological ...

Genomic wide selection is a promising approach for improving the selection accuracy in plant breeding, particularly in species with long life cycles, such as Jatropha. Therefore, the objectives of this study were to estimate the genetic parameters for grain yield (GY) and the weight of 100 seeds (W100S) using restricted maximum likelihood (REML); to compare the performance of GWS methods to pre...

Using enzyme polymorphism at IO loci , genetic variation was analysed in both wi ld and cuiti vated olive growing around the Mediterranean Basin. Twenty five and 21 alle1es were observed in the 333 wild olive trees analysed and in the culti ved materia1 (418 trees) respectively. Twenty one of these alleles were common to the two forms. In addition, in most the situations of sympatry between wil...

Cytosine DNA methylation is the addition of a methyl group to the 5' position of a cytosine, which plays a crucial role in plant development and gene silencing. Genome-wide profiling of DNA methylation is now possible using various techniques and strategies. Using these technologies, we are beginning to elucidate the extent and impact of variation in DNA methylation between individuals and/or t...

Urtica dioica is an important medicinal plant which is widely distributed in Mazandaran province (North of Iran). In this study for the first time Amplified Fragment Length Polymorphism (AFLP) and Inter-simple Sequence Repeat (ISSR) markers were used for detection of genetic polymorphism in Mazandaran nettle. Ten AFLP primer combinations and seventeen ISSR markers were utilized. AFLP produced 830...

It has recently been argued [8], [9] that rate of evolution at the molecular level is greater than can be accounted for by natural selection and hence that a large part of observed molecular changes must be selectively neutral. This discussion will be concerned with some experimental results, from studies of a number of different species of plants, that bear on this question. These results will...
