Differential Expression Of Soluble Pyrophosphatase Isoforms In Arabidopsis Upon External Stimuli, Zahi̇de Nesli̇han Öztürk, Steffen Greiner, Thomas Rausch
Turkish Journal of Botany
In plants, pyrophosphate (PPi), generated in a wide range of reversible anabolic reactions, is hydrolyzed by pyrophosphatases. The presence of tonoplast- and Golgi-integral H+-translocating pyrophosphatases in plants led to the conclusion that plant cytosol has no soluble pyrophosphatase activity. However, the Arabidopsis thaliana (L.) Heynh. Genome also encodes five soluble pyrophosphatase isoforms (Ppas). There are almost no data in the literature on their redundancy in plant metabolism; therefore, we performed expression analyses of A. Thaliana soluble pyrophosphatase isoforms in response to external stimuli including carbohydrate status, hormone action, and stress exposure. The results revealed pronounced specificity for each isoform. Interestingly, …

Activated Expression Of Eshd1 Enhances Drought Tolerance In Tobacco Plants Via Mitigation Of Reactive Oxygen Species-Mediated Membrane Damage, Cheng Zhou, Zhongyou Ma, Lin Zhu, Jiansheng Guo, Xianghuan Cui, Jian Zhu, Jianfei Wang
Turkish Journal of Botany
It is well documented that the homeodomain-leucine zipper (HD-Zip) transcription factors play diverse roles during plant growth and development. The Class I HD-Zip genes are shown to be involved in the regulation of abiotic stress responses and tolerance. Herein, a novel Class I HD-Zip gene, EsHD1, was isolated from Eutrema salsugineum, and an investigation was performed of its physiological functions in response to drought stress. The analyses of gene expression profiles revealed that the EsHD1 transcripts quickly accumulated upon exposure to various abiotic stress conditions or abscisic acid treatments. Furthermore, the overexpression of EsHD1 in tobacco plants conferred improved tolerance …

Estimating Genetic Diversity Among Selected Cotton Genotypes And The Identificationof Dna Markers Associated With Resistance To Cotton Leaf Curl Disease, Ammad Abbas, Muhammad Atif Iqbal, Mehboob-Ur Rahman, Andrew H. Paterson
Turkish Journal of Botany
To the extent of our knowledge, applications of DNA markers in marker-assisted breeding of cotton are handicapped due to low genetic diversity in cotton germplasm. Cotton leaf curl disease, a disease of viral origin, has substantially depressed cotton production in Pakistan, and this disease is also an emerging threat to the neighboring cotton-growing countries like China and India. The present study was designed to identify DNA markers, predominately simple sequence repeats (SSRs), associated with tolerance and/or resistance to the disease. Based upon 2 years of disease-screening field experiments, a total of 10 cotton genotypes (five highly tolerant, four highly susceptible, …
