Expanding The Understanding Of A Forest Ectomycorrhizal Community By Combining Root Tips And Fruiting Bodies: A Case Study Of Tuber Magnatum Stands, Giorgio Lalli, Marco Leonardi, Marilena Oddis, Giovanni Pacioni, Elena Salerni, Mirco Iotti, Alessandra Zambonelli
Turkish Journal of Botany
A survey of both ectomycorrhizal (ECM) root tips and fruiting bodies of ECM fungi was carried out during a four-year period (2009-2012) in two similar forest stands in central Italy, previously investigated in detail being habitats of the Italian white truffle Tuber magnatum Pico. This research is one of the few conducted in mixed forest stands and, for the first time, it took into account the cryptic fungi (corticiaceous, hypogeous, and sclerotia). This survey led to an exhaustive description of the ECM community by integrating all the 197 taxa recorded (147 species as fruiting bodies, 65 as ectomycorrhizas, and 15 …

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, …

Turkish Journal of Botany
Identification of vacuolar Na+/H+ antiporters facilitates the basis of salt stress tolerance mechanisms. Na+ accumulation into the vacuole is crucial for the avoidance of cytoplasmic Na+ toxicity. In this study, we show that the introduction of AtNHX1 into tobacco generated more tolerant plants when compared to wild-type plants. Transgenic tobacco plants exhibited higher germination rates in the presence of increasing salt concentrations compared to wild-type plants. In addition, proline levels were higher under salt stress conditions in both the shoots and the roots of transgenics compared to wild-type plants. Increase in malondialdehyde production during lipid peroxidation by salinity was lower …

Polyploidy was recorded for the first time for this species in Tunisia. Most of the populations were diploid (17 populations), whereas two populations were tetraploid and only one was …
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 …

Iron (Fe) deficiency is one of the major yield-limiting factors in peanut (Arachis hypogaea L.), especially when grown in calcareous soils. The soils of the Pothwar region in Pakistan are calcareous in nature, exposing peanut to Fe deficiency. The molecular mechanisms governing Fe deficiency response in peanut have not been fully revealed. We compared 4 locally important varieties of peanut to evaluate Fe deficiency responses at the molecular level. The expression profiles of 7 important genes including AhIRT1, AhFRO1, AhNRAMP1, AhYSL1, AhYSL3.1, AhYSL4, and AhYSL6 in roots and young and old leaves of local peanut varieties were investigated 19 days …
