Bread wheat (Triticum aestivum) is the most commonly grown crop due to its adaptation in a wide range of ecogeographical conditions and providing enhanced food assurance to the modern world. A diverse and rich collection is the foundation of each successful wheat improvement program. Therefore, major efforts are in progress worldwide to boost wheat production by broadening genetic diversity. Accepting this issue as a target, present study gives an overview of the major progress in the diversity and population evaluation of Indian and Turkish hexaploid wheat employing ISSR and RAPD primers. Various statistical analyses were employed for determining the hexaploid wheat population structure of India and Turkey. Results of dendrogram, scatterplots, Analysis of Molecular Variance (AMOVA) and population structure analysis were found in accordance with each other. All the experimental genotypes were clustered in two main groups, one group containing Indian varieties and another group containing both Indian and Turkish varieties reflecting the direct or indirect interbreeding among the populations of the two countries. Utilizing the genetic association of Indian and Turkish hexaploid wheat population, based on genetic distance estimated in the study, researchers worldwide may include Indian and Turkish hexaploid varieties in the wheat improvement programs and can evade the likelihood of selected germplasm becoming hereditarily consistent.


Assessment of genetic variation of bread wheat varieties using microsatellite markers
Akkaya, Mahinur; Buyukunal-Bal, EB (2004-01-01)
The DNA fingerprinting profiles of 11 bread wheat cultivars, grown in Turkey, was obtained by using 19 highly polymorphic wheat microsatellites. Up to six randomly selected individuals from each of these cultivars were subjected to analysis. Estimated polymorphism information content (PIC) values among 65 individual genotypes for 19 loci were between 0.36 and 0.87 with an average value of 0.68. The numbers of observed alleles were between 2 and 9, with an average value of 5.42. These relationships were asse...
Identification of proteins interacting with tagged-pathogen effector protein in agro-delivered planta
Dagvadorj, Bayantes; Akkaya, Mahinur S.; Günel, Aslıhan; Department of Biotechnology (2012)
Wheat is one of the most essential food sources in the world. However, there has been serious yield loss of wheat production due to stripe rust disease caused by the fungal pathogen Puccinia striiformis f. sp. tritici. The cost-effective and long-lasting defense to the disease can be achieved by generating genetically resistant crops against the disease forming pathogens. To accomplish this, first step is to acquire knowledge in the plant pathogen interactions of the crop and the pathogen of interests at th...
Identification and cloning of genes induced and / or repressed upon treatments of wheat plants (avocet s) with BTH, BABA and Trichoderma Harzianum Raifi KRL-AG2
Al-Asbahi, Adnan; Akkaya, Mahinur S.; Department of Biotechnology (2006)
One of the major problems concerning the production of food crops is the controlling of plant diseases to maintain the high quality and yield. Wheat diseases are caused by parasitic bacteria, fungi and viruses that are a major hazard in wheat production. Therefore, understanding of any resistance mechanism is prerequisite for the successful utilization of wheat crop species in modern agriculture. The phenomenon of induced resistance by fungi, bacteria, microbial elicitors and chemicals has been investigated...
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 ...
Expression analysis of NAC type transcription factors on wheat seedlings under abiotic stress conditions
Baloğlu, Mehmet Cengiz; Yücel, Ayşe Meral; Öktem, Hüseyin Avni; Department of Biology (2011)
Wheat is the most important grain crop grown in our country providing greatest part of the daily nutritional requirement. Abiotic factors including salinity, drought, cold and heat stresses affect quality and yield of wheat varieties used for the production of both bread and pasta flour. NAC proteins form one of the widest families of plant specific transcription factors. Members of this family are related with development, defense and abiotic stress responses. TaNAC69-1 and TtNAM-B2 genes were isolated fro...
