Plants are the most important source of Fe for humans and animals; therefore, its accumulation in edible plant parts is great importance. Since species, ecotypes, genotypes, lines, varieties may differ their ability to accumulate mineral elements, aim this study was i) examine grain Aegilops Triticum species with different genomes (AA, BB, BBAA, BBAADD), ii) relationship between level ploidy ac...

B chromosomes (Bs) are dispensable components of the genome exhibiting non-Mendelian inheritance. Chromosome counts and flow cytometric analysis of the grass species Aegilops speltoides revealed a tissue-type specific distribution of the roughly 570 Mbp large B chromosomes. To address the question whether organelle-to-nucleus DNA transfer is a mechanism that drives the evolution of Bs, in situ ...

With respect to the maternally inherited large subunit of fraction I protein, Chen et al. (1) found that Triticum boeoticum and T. urartu had identical polypeptide patterns, and Aegilops speltoides had a different one identical with that of the tetraploid wheats. From this evidence they inferred that Ae. speltoides. but neither T. boeoticum nor T. urartu, could have been the maternal parent of ...

in order to investigate the effect of phosphorus fertilizer and spraying fe chellat in micronutrients absorption rate, rate of proline and soluble carbohydrates in bread wheat and some of its ancestral species in dryland condition, a factorial experiment was conducted with three factors consist of: p fertilizer (in two levels), spraying fe chellat (in two levels) and different species of wheat ...

Microsatellites are an important constituent of plant genome and distributed across entire genome. In this study, genome-wide analysis of microsatellites in 8 Triticeae species and 9 model plants revealed that microsatellite characteristics were similar among the Triticeae species. Furthermore, genome-wide microsatellite markers were designed in wheat and then used to analyze the evolutionary r...

Common wheat (Triticum aestivum) has for decades been a textbook example of the evolution of a major crop species by allopolyploidization. Using a sophisticated extension of the PCR technique, we have successfully isolated two single-copy nuclear genes, DMC1 and EF-G, from each of the three genomes found in hexaploid wheat (BA(u)D) and from the two genomes of the tetraploid progenitor Triticum ...
