Mitochondrial Dna-Related Disorders: Emphasis On Mechanisms And Heterogeneity, Umut Cagin, Jose Antonio Enriquez Jan 2015

Mitochondrial Dna-Related Disorders: Emphasis On Mechanisms And Heterogeneity, Umut Cagin, Jose Antonio Enriquez

Turkish Journal of Biology

Mitochondrial diseases are a heterogeneous group of disorders that are currently the focus of intense research. The many cell functions performed by mitochondria include ATP production, calcium homeostasis, and apoptosis. One of the unique properties of mitochondria is the existence of a separate mitochondrial genome (mitochondrial DNA, mtDNA) found in varying copy numbers and containing 37 genes, 13 of them encoding proteins. All 13 mitochondrially encoded proteins form part of oxidative phosphorylation complexes through combination with approximately 100 nuclear DNA-encoded proteins. Coregulation of nDNA and mtDNA is therefore essential for mitochondrial function, and this coregulation contributes to the heterogeneity and …

Turkish Journal of Agriculture and Forestry

Quantitative trait loci (QTLs) for flowering time (FT) in lentil were located using a recombinant inbreed line population derived from an intraspecific cross of Precoz × WA8649041. Experiments for FT were conducted in 2 locations (Haymana, Turkey and Pullman, WA, USA) for 5 years (from 1998 to 2002 in both Pullman and Haymana). A linkage map was constructed using 149 markers (RAPD, AFLP, ISSR, SSR, and 2 morphological markers) located on 11 linkage groups (LGs). Analysis of variance of FT was found to be significant for all locations and years. One major QTL for FT was identified on LG6 across …

Aquaporins As Targets For Stress Tolerance In Plants: Genomic Complexity And Perspectives, Wonkeun John Park, Benjamin Todd Campbell Jan 2015

Aquaporins As Targets For Stress Tolerance In Plants: Genomic Complexity And Perspectives, Wonkeun John Park, Benjamin Todd Campbell

Turkish Journal of Botany

As a multigene family, plant aquaporins function not only in water transport but also in transport of small elements that are important for vegetative and reproductive growth of plants. Increasing evidence exhibits the relevance of aquaporins to tolerance against abiotic and biotic stresses such as drought, nutrient deficiency, and herbivore attack. With the accumulation of crop genome sequencing, it is suggested that several aquaporin genes are conserved in subchromosomal locations as tandem duplicated members. In this review, we will discuss the compelling nature of aquaporins as multifunctional transport channels that are often encoded in clustered regions of genomes and relevant …

Role Of Autophagy In The Pathogenesis Of Alzheimer Disease, Muhammet Cemal Kizilarslanoğlu, Zekeri̇ya Ülger Jan 2015

Role Of Autophagy In The Pathogenesis Of Alzheimer Disease, Muhammet Cemal Kizilarslanoğlu, Zekeri̇ya Ülger

Turkish Journal of Medical Sciences

Alzheimer disease (AD) is the most common progressive neurodegenerative disorder causing increased morbidity and mortality. It is characterized by accumulation of amyloid-β in neurons. As there is no known definitive treatment of this disorder, studies trying to determine its exact pathogenetic pathways and target therapies for these specific pathways are being rapidly conducted. Autophagy is one of the areas of interest in studies on the pathogenesis of AD. It is a process of self-digestion that is thought to be a response to stressors and allows cells to adapt to environmental changes. There is accumulating evidence showing an association between autophagy …
