Cultivated wheat, (Triticum aestivum L.), is one of the most important food crops in the world. The Aegilops L. genus is frequently utilized by plant breeders for improving the current wheat cultivars due to their close relationships. Therefore, understanding the phylogenetic relationships among the species of these genera is not only valuable for plant taxonomy, but also for plant breeding efforts. The presented phylogenetic analysis was based on the sequences of trnT-F chloroplast DNA containing three non-coding sub-regions. Twelve genotypes belonging to four species of Triticum L. genus and twenty-four genotypes belonging to eight species of Aegilops genus were used in the current study. The results postulated a close genetic relationship between diploid Aegilops species containing the BB genome and polyploid Triticum species. With the exception of Aegilops cylindrica Host (CCDD), all other Aegilops species having the CC genome were alienated from Aegilops speltoides Tausch (BB) and clustered together. These two clusters joined by a third cluster including the AA genome containing diploid Triticum species.

From RFLP to DArT: molecular tools for wheat (Triticum spp.) diversity analysis Khan, Mohd Kamran; Pandey, Anamika; Choudhary, Saumya; HAKKI, ERDOĞAN EŞREF; Akkaya, Mahinur; Thomas, George (Springer Science and Business Media LLC, 2014-06-01) Wheat (Triticum spp.) is a universally lucrative agricultural crop. An increase in wheat production has been shown through selection by the farmers which can increase the grain profitability. The determination of genetic associations among domestic cultivars is facilitated by molecular markers. Data on genetic polymorphism is valuable for the germplasm association and regarding the developing management strategies. The information would be supportive for potential genome mapping programs and for the relevan...
Site directed mutations of one of the plant pathogen effector gene for functional analysis Mustafa, Zemran; Akkaya, Mahinur S.; Department of Biochemistry (2015) Wheat (Triticum aestivum L.) is one of the most important crops planted in the world and used as major food resource. Yet, there are major losses of productivity due to different biotic and abiotic destructive agents. Among the biotic factors especially the yellow rust is one of the most frequent. Yellow rust or also called “stripe rust”, due to stripe like appearances on the leaves, disease is caused by Puccinia striiformis f. sp. tritici, which is an obligate plant fungal pathogen. To cope with high yield...
Genetic relationships among perennial and annual Cicer species growing in Turkey as revealed by allozymes Sudupak, MA; Kence, Aykut (Springer Science and Business Media LLC, 2004-05-01) Allozyme polymorphisms were used to assess genetic variation and relationships among ten Cicer species ( annuals and perennials) growing in Turkey. Using seven enzyme systems, 12 putative scorable loci were detected and surveyed for polymorphism in an accession collection including wild and cultivated forms. Variation was generally low within accessions and species, but common between species. Cluster analysis based on the pairwise genetic distance coefficients (Nei 1978) among accessions and species using ...
Genetic diversity of scald (rhynchosporium secalis) disease resistant and sensitive Turkish barley seed sources as determined with simple sequence repeats Dizkırıcı, Ayten; Kaya, Zeki; Department of Biology (2006) Scald disease (Rhynchosporium secalis) is one of the major plant diseases causing considerable yield loss in barley (Hordeum vulgare) plantations in Turkey. To develop, scald resistant barley varieties, C.R.I.F.C. of Turkey has a large accumulated collection of barley seed sources in hand, but these samples are difficult to be followed and used in the breeding programs due to lack of genetic studies on them. Thus, the objective of this study was to characterize and fingerprint of eighty barley seed sources,...
Genetic screening of Turkish wheat varieties for the durable resistance gene, Lr34 Boylu, Barış; Akkaya, Mahinur S.; Hakkı, Erdoğan Eşref; Department of Biotechnology (2011) Wheat diseases such as rusts and powdery mildews are among the most important and ancient diseases that affect wheat cultivation worldwide. The pathogen race specific resistance genes cannot maintain long lasting resistance. On the other hand, the presence of genes confers the non-race specific resistance last much longer. The durable resistance phenotypes in wheat against various rust and powdery mildew diseases were reported as Lr34, Yr18, and Pm38 separately; nevertheless, they were known to locate very ...
