Turkish Journal of Botany
Several species within the genus Lotus are important forage crops, and many are endangered or rare. Despite the high genetic diversity of the genus, identification of Lotus species is problematic because of the limited number of reliable morphological markers. In search of a quick, inexpensive, and steady method for species identification, genome size and cell cycle/endoreduplication intensity of 14 accessions belonging to eight Lotus species were estimated by flow cytometry. ISSR-PCR was also applied to find sensitive molecular markers for genetic diversity estimation. Genome size estimation revealed that Lotus species possess very small genomes and this characteristic enables the identification …

Turkish Journal of Botany
Protein disulfide isomerase (PDI) and PDI-like genes encode key foldase enzymes that play an important role in disulfide bond formation, isomerization, and many other metabolic functions in plants. Our previous results indicate that the PDI-V expression is tissue-specific and that it is upregulated by powdery mildew and other abiotic stress treatments. In the current study, the complete PDI-V gene and its promoter sequence were cloned to identify gene structure and the important cis-regulating motifs responsible for various genes' activities. Sequence analysis revealed the size of the cloned genomic sequence and promoter region as 5728 bp and 2086 bp, respectively. The …

Molecular Cloning And Characterization Of Ipomoea Nil Metallothioneins, Agnieszka Mierek-Adamska, Zuzanna Znajewska, Anna Goc, Grazyna Dabrowska
Turkish Journal of Botany
Metallothioneins are low-molecular-weight, cysteine-rich proteins able to bind a variety of heavy metal ions. They are involved in the maintenance of micronutrient homeostasis and detoxification of nonessential heavy metals. Plant metallothioneins are classified into four main types based on the number and arrangement of cysteine residues. Here we report on the isolation of novel complementary and genomic DNA from a model for a short-day plant, Ipomoea nil (Japanese morning glory), that encodes 66- or 76-amino acid residue proteins. In silico and phylogenetic analysis of putative amino acid sequences confirmed that these 66- and 76-amino acid residue proteins belong, respectively, to …

Understanding the mechanisms of how environmental factors limit species distribution along environmental gradients is a central question in ecology. This study aimed to understand species acclimation in view of photosynthetic parameters in an arid mountainous region. We measured some photosynthetic parameters and light and CO2 photosynthesis response curves for all plant communities with seven dominant species in 13 sites along an elevation gradient in the Qilian Mountains in arid northwestern China. The results showed that species in xerothermic environments had low maximum rate of carboxylation (Vcmax) (14.5 μmol m-2 s-1) and maximum rate of electron transport (Jmax) (22.7 μmol m-2 …
Phenotypic Plasticity And Specialization Along An Altitudinal Gradient In Trifolium Repens, Fati̇h Fazlioğlu, Justin S.H. Wan, Stephen P. Bonser
Phenotypic Plasticity And Specialization Along An Altitudinal Gradient In Trifolium Repens, Fati̇h Fazlioğlu, Justin S.H. Wan, Stephen P. Bonser
Turkish Journal of Botany
Phenotypic plasticity and specialization represent seemingly contrasting strategies to heterogeneous environments. Specialization is associated with the loss of phenotypic plasticity, particularly in functional traits. However, it is equivocal if this loss of plasticity is observed only in the specific habitat and stress type where the specialization occurs or a general loss of plasticity is seen across habitats. We examined populations of Trifolium repens L. following an expansion during the colonization of Australia from relatively good low altitude habitats to more stressful high altitude habitats in the Blue Mountains region, New South Wales, Australia. We examined if specialization to abiotic stress …

The Morphological Intermediacy Of Erigeron ×Huelsenii (Asteraceae), A Hybrid Between E. Acris And E. Canadensis, Artur Pliszko, Kinga Kostrakiewicz-Gieralt
Turkish Journal of Botany
Morphological intermediacy is considered the first evidence of hybridization in many plant studies. However, morphological intermediacy does not always provide hybrid origin and can be a result of divergence. In this study, the authors revised the morphological intermediacy of Erigeron ×huelsenii, a putative hybrid between the Eurasian E. acris s. str. and North American E. canadensis, using the character count procedure, a method that allows distinguishing hybridity from divergence. The measurements were made on herbarium specimens, including 100 specimens of E. acris s. str., 100 specimens of E. canadensis, and 50 specimens of E. ×huelsenii, which were collected in northeastern …
