GASA (Gibberellic acid stimulated in Arabidopsis) is an important gene family that has important roles in both the developmental and physiological processes. In this study, 23 GASA genes in common bean were identified and detailed bioinformatics analyzes were conducted at both gene and protein levels. Pvul-GASA proteins were categorized into three clusters, and a total of 13 duplication events (12 segmental and one tandem) were shown to play a role in the expansion of the GASA gene family in Phaseolus vulgaris L. The identified Pvul-GASAs have been shown to be linked to stress and hormone signaling pathways. In addition, some …

Turkish Journal of Botany

Onosma L., the largest genus of Boraginaceae, is represented by 105 species in Turkey with an endemism rate of 52%. Phytochemical studies indicate that Boraginaceae plants mainly comprise naphthoquinones with a wide range of biological activities including anticancer, antiinflammatory, wound healing, and antioxidant effects. However, few taxa of the genus Onosma have been investigated in detail for their bioactivities. Considering the high rate of endemism and an inadequate number of bioactivity screening studies in literature, we aimed to evaluate the cytotoxic effects and topoisomerase inhibitory activities of some Onosma species growing in southwestern Turkey. Here, we describe a comprehensive cytotoxic …

Phylogeny And Taxonomy Of A Novel Species Of Pseudocercospora From India, Archana Singh, Paras Nath Singh, Gopal Nath, Nawal Kishore Dubey

Turkish Journal of Botany

A new species of Pseudocercospora is described causing leaf spot disease on Crotalaria assamica from India. The identity of isolate was based on asexual morphs, cultural characteristics and phylogenetic analyses of partial nuclear ribosomal 28S large subunit and complete internal transcribed spacer rDNA sequence data with high statistical support value. Morphologically this species has characters similar to allied species in genus Pseudocercospora but differs in having catenate and branched conidia. Phylogenetic analysis using LSU and ITS reveals it a new species of >i>Pseudocercospora (Capnodiales, Mycosphaerellaceae).


The Involvement Of The Induction Of Anthocyanin Biosynthesis And Transport In Toxic Boron Responsive Regulation In Arabidopsis Thaliana, Ceyhun Kayihan Jan 2021

The Involvement Of The Induction Of Anthocyanin Biosynthesis And Transport In Toxic Boron Responsive Regulation In Arabidopsis Thaliana, Ceyhun Kayihan

Turkish Journal of Botany

Recently, boron (B) has been found to form a complex with anthocyanin, which could be evidence for the B tolerance mechanisms that reduce free B in the leaf tissues of plants. However, the molecular mechanism of anthocyanin biosynthesis and transport has not been satisfactorily elucidated in plants exposed to toxic B. Therefore, the changes in expression levels of some of the phenylpropanoid pathway genes, early and late flavonoid biosynthetic genes, and transcription factors related to anthocyanin biosynthesis and transport were determined in Arabidopsis thaliana under B toxicity. Accordingly, 1 mM boric acid treatment did not cause any significant change in …

Genetic Structure Of Zannichellia L. Populations According To Mountain Barriers In Iranas Revealed By Issr And Srap Markers, Shabnam Abbasi, Saeed Afsharzadeh, Mehri Dinarvand

Turkish Journal of Botany

Zannichellia L. (Potamogetonaceae) is a widespread aquatic genus that is distributed in temperate and subtropical aquatic ecosystems worldwide. Because the biogeographical location of Iran includes mountain ranges and deserts that may cause different habitat types, it was assumed that these Zannichellia populations would be stronger differentiated than observed in Zannichellia from temperate regions. The present study aimed to test whether Z. palustris would demonstrate high levels of genetic differentiation over long distances and across mountain ranges. The genetic structure of the populations of Zannichellia was investigated using inter simple sequence repeats (ISSR) and sequence-related amplified polymorphism (SRAP) as molecular markers. …

Bioassessment Of Water Quality Of Surface Waters Using Diatom Metrics, Abuzer Çelekli̇, Haciömer Lekesi̇z, Mehmet Yavuzatmaca

Turkish Journal of Botany

Bioassessment of surface waters is one of the most important approaches to predict the deterioration of ecosystems and achieve environmental sustainability according to the application of the European Water Framework Directive. The present review emphasizes the importance of the bioassessment of freshwater quality especially running waters based on diatom metrics. Nutrient enrichment and hydromorphological alternation driven by human activities are the main factors for the ecological compromise of freshwater ecosystems. Currently, the bioassessment of the ecological condition of inland water bodies is adopted worldwide. Bioassessment is complementary to physicochemical and hydromorphological data for evaluating the ecological conditions of rivers; however, …

Turkish Journal of Botany

Using chemicals known as inhibitors of chromatin remodeling enzymes is a useful approach in understanding the regulation machinery that contributes to the maintenance of or conversion to a pluri- and totipotent states of the cells in multicellular organisms. They can serve as tools to reveal the molecular and cellular mechanisms required for reprogramming. A deeper understanding of reprogramming pathways that drive the cell into a dedifferentiated state might help us enhance plant micropropagation and green biotechnology applications. Chaetocin is one of the histone methyltransferase inhibitors known as key drivers in several cellular processes. It was shown that chaetocin enhanced the …

Running Sigmas Analysis Of Sampled Molecular Paraphyly In Pottiaceae (Bryophyta), Richard Zander

Turkish Journal of Botany

A spreadsheet dealing with standard deviations allows statistical examination of continuous variables associated with paraphyly in systematics, with examples in the Pottiaceae (Bryophyta). Outlier values in taxonomic representation of distribution with the structure of (w-)x-y(-z) of continuous variables can be empirically supported. The use of the geometric mean and intuitional estimation is reexamined. Published reports of the distance between maximally distant exemplars of individual paraphyletic species in molecular cladograms in several studies were reevaluated as metadata. Levels of standard deviations were assigned with the Running Sigmas spreadsheet. A spike in width of exemplars of a paraphyletic species of a moss …
