Investigation of aberrations caused by gamma radiation in mitosis and meiosis might be fundamental to elucidate the interaction between radiations and biological systems. To identify the effects of the various doses of gamma radiation (25, 35, 45, 55 Gy) on mitotic and meiotic traits and agronomical features, a field experiment and microscopy assay...

In order to identify QTLs associated with stemlet and rootlet growth in the early stages of germination of wheat, 144 recombinant inbred lines derived from the cross of Kaz and Mantana were evaluated in a completely randomized design. The linkage map using composite interval by 234 microsatellite (SSR) primers and 267 AFLP loci have been already pr...

Plant peroxidases belong to a multigene family and possess highly conserved domains allowing designing oligonucleotide primers to amplify DNA sequences coding for peroxidases from plants with unsequenced genomes. Peroxidase gene-based polymorphism among wild Pistacia species, and correlation between peroxidase markers were deduced in this study. Wi...

Considering the importance of impact of heat stress on reproductive organs in wheat and to study the effects of stress on germination percentage of pollen and pollen tube length on 10 wheat cultivars, which include Kaz, Mantna, Gohar, Kuhdasht, Zagros, Alvand, Atrak, Durum, Nyknzhad and Chamran at 25, 30, 35, 40 and 50 degrees Celsius in the form o...

With consideration of harvest index and relationship with grain yield the experiment for locating locus of genes that control of harvest index in two normal and heat stress condition that used inbred lines population of wheat recombinant inbred line population that containing 144 recombinant inbred lines derived from the cross between Kaz (tolerant...

Sugarcane is one of the most important industrial plants. There are many ways to improve the agronomic traits of this plant, such as genetic engineering and gene transfer methods. These modern techniques depend on optimizing the regeneration of plants from callus tissue. In this study, we attempted to optimize all different stages of tissue culture...

Genetic diversity is the base of breeding activities and mutation could increase the genetic diversity in plants. Mutagenesis is a process in which permanent changes occur in the genetic material of an organism. Mutation breeding is a method for improving crops, based on the genetic change in the vegetative parts, gametes or seeds by exposing them...

Wheat is one of the most important crops for food production. SSR and AFLP markers are common markers for QTL detection. QTL detection can help to understand the details of genes controlling traits and marker-assisted selection to proceed. For detection of QTL linkage map covering 20 wheat chromosomes were used. For this purpose, 144 recombinant in...

To study the effects of high temperature on the meiosis of pollen mother cells (PMCs) and to determine their relationship with grain set, two in situ experiments were conducted between 2010 and 2012 on four wheat cultivars, Kauz, Montana, M6 and Chamran, under normal (normal cultivation) and terminal heat stress (late cultivation) conditions. Due t...

A 1342 bp fragment, AFHA, was amplified by PCR from Aeluropus littoralis genomic DNA and its nucleotide sequence was determined. The sequence analysis showed that the fragment was amplified from a gene that codes for a plasma membrane H +-ATPase. The primers were designed based on the highly conserved sequence of plant plasma membrane H +-ATPases....

Understanding milk thistle genetic diversity is essential for breeding programs of this plant. In order to investigate genetic diversity of some Iranian ecotypes, an experiment was performed based on randomized complete block design in three replications using Iranian collected ecotypes and foreign cultivar" Bodaklazi" in the experimental field of...

Improving grain performance under water-limited conditions essentially depends on the knowledge of water–yield relationships. The current project was set up to make a field evaluation of relations among grain yield, water use efficiency (WUE), and its components, i.e., transpiration efficiency (TE), uptake efficiency (UE), and harvest index (HI) in...

A metabolic depletion syndrome was discovered at early vegetative stages in roots of salt sensitive rice cultivars after prolonged exposure to 100mM NaCl. Metabolite profiling analyses demonstrate that this syndrome is part of the terminal stages of the rice salt response. The phenotype encompasses depletion of at least 30 primary metabolites inclu...

Hepatitis B virus (HBV) is one of the most serious infectious diseases among human races worldwide. It is estimated that nearly 5% of world population are chronic carriers of HBV. Derivation of the hepatitis B vaccines from yeast and mammalian cells are tedious and expensive, so it can limit the use of these vaccines in developing countries. Biolog...

Evaluating adaptable physiological traits involved in the response of plants to drought stress could lead us to improve drought tolerant cultivars. In this regards, the current project was conducted under a line-source sprinkler irrigation system. Eight commercial and advanced bread wheat (Triticum aestivum L.) cultivars, all of which are cultivate...

New metabolic profiling technologies provide data on a wider range of metabolites than traditional targeted approaches. Metabolomic technologies currently facilitate acquisition of multivariate metabolic data using diverse, mostly hyphenated, chromatographic detection systems, such as GC-MS or liquid chromatography coupled to mass spectrometry, Fou...
