Palms are known to be an important and diverse angiosperm component in the Deccan Intertrappean beds of Central India. However, the report of fossilized palm stems inhibiting saprophytic fungal remains is empty in the field of paleobotany. Here, we document for the first time the occurrence of fungal remains in a petrified palm stem collected from the latest Maastrichtian (Late Cretaceous)-earliest Danian (early Paleocene) sediments of the Deccan Intertrappean beds of Madhya Pradesh, Central India. The anatomical features of the fossil stem are characterized by the presence of Corypha-type general stem pattern (progressive decrease of fibrous parts of fibrovascular bundles, …
Identification Of Carrying Alien Dna Fragments In Solanum Melongena X Solanum Incanum Interspecific Progeny By Using Cosii Marker, Görkem Sülü, İlknur Polat, Hati̇ce Fi̇li̇z Boyaci, Ahmet Naci̇ Onus

Cultivated eggplant (Solanum melongena L.) is produced in many countries with temperate and tropical climates and has great economic importance. In recent years, resistance to biotic and abiotic stress conditions in addition to increasing yield and quality has gained importance in plant breeding including eggplant breeding. Therefore, the wild relative S. incanum is an important parent in breeding studies as it provides resistance to some important biotic and abiotic stresses for eggplant. It is possible to obtain a fully fertile hybrid between the two species, as well as to establish F2 lines. However, it is a mystery whether there is …

Isolation And Assessment Of Halophilic Rhizobacteria Plant Growth-Promoting Traits For Alleviating Salt Stress In Wheat, Alev Sezen, Ömer Faruk Algur, Ferruh Aşçi, Arzu Ünal
Turkish Journal of Botany
In this study, 22 halophilic bacteria were isolated from plants collected together with rhizosphere soil from habitats with high salt content in and around Erzurum. Various plant growth-promoting (PGP) properties of these isolates (nitrogen fixing, phosphate solubilizing, ACC deaminase, and IAA and siderephore production) were determined. Bacteria positive for PGP properties and various combinations with these bacteria were subjected to pot experiments in saline medium (greenhouse conditions) and their effects on growth parameters (root and stem length, fresh and dry weight, protein, and chlorophyll and carotenoid content) of wheat plants were determined. As a result of the research, the isolates …

A New Fossil Wood Species Of Ziziphus From The Middle Miocene Of Türkiye And Its Palaeoenvironmental Evaluation, Ünal Akkemi̇k, Özlem Toprak
Turkish Journal of Botany
The purpose of this study is to describe a new fossil wood from the Middle Miocene of South Anatolia (Mersin) and to identify it and evaluate its palaeoenvironmental implications. Thin sections of transverse, tangential, and radial surfaces were examined and described using the terminology of the International Association of Wood Anatomists. The wood was determined to have characteristics of Ziziphus (Rhamnaceae). It is the first fossil wood of Ziziphus and is described as Ziziphoxylon sayaz Akkemik sp. nov. It is from the Middle Miocene Climate Optimum (MMCO), which is a relatively warm interval in the Miocene. Indistinct annual growth ring …
Dorycnium Vuralii (Fabaceae), A New Species From Türkiye, Bilal Şahi̇n, Seher Karaman, Mevlüde Alev Ateş, Zeki Aytaç
Dorycnium Vuralii (Fabaceae), A New Species From Türkiye, Bilal Şahi̇n, Seher Karaman, Mevlüde Alev Ateş, Zeki Aytaç
Turkish Journal of Botany
The present study describes a new species Dorycnium vuralii (Fabaceae) from Çankırı, Türkiye. The new species is compared morphologically to the taxa of sect. Bonjeanea and sect. Dorycnium along with pollen micromorphology, leaflet, and seed micromorphology. The geographical distribution of Dorycnium vuralii is mapped. The phylogenetic relationships between the new species and other closely related species in the genus are inferred based on DNA data from both cpDNA and nrDNA (rbcL1&ITS). Although phylogenetic implications are different in the two DNA barcoding regions, D. vuralii is shown to be a new species in both molecular data. The new species is assessed …
Genetic Variation In White Poplar (Populus Alba L.) Populations As Characterized By Ssr Markers, Burcu Uzan Eken, Emrah Kirdök, Ercan Veli̇oğlu, Yelda Özden Çi̇ftçi̇
Genetic Variation In White Poplar (Populus Alba L.) Populations As Characterized By Ssr Markers, Burcu Uzan Eken, Emrah Kirdök, Ercan Veli̇oğlu, Yelda Özden Çi̇ftçi̇
Turkish Journal of Botany
The white poplar (Populus alba L.), which is tolerant to abiotic and biotic stresses, is a tree species that is resilient against changing climatic and environmental conditions, which makes it a suitable candidate for afforestation efforts. However, due to prolonged human intervention associated with the increasing population, the genetic resources of this species are at risk of loss. Additionally, while this species generally reproduces sexually, reproduction clonally via its root suckers has become widespread in some areas. Hence, the aim of this study was to investigate the genetic diversity of white poplar, which is increasingly experiencing genetic diversity loss. Herein, …
A Comprehensive Study On The Molecular Characterization Of Tomato Spotted Wilt Orthotospovirus Isolates And Resistance Genes In Pepper And Tomato, Qurat Ul Ain Sajid, Emi̇nur Elçi̇
A Comprehensive Study On The Molecular Characterization Of Tomato Spotted Wilt Orthotospovirus Isolates And Resistance Genes In Pepper And Tomato, Qurat Ul Ain Sajid, Emi̇nur Elçi̇
Turkish Journal of Botany
Tomato spotted wilt orthotospovirus (TSWV, Orthotospovirus tomatomaculae) resistance genes (Tsw, Sw5) have been identified in pepper and tomato plants. The development of resistant cultivars is one of the popular management strategies for overcoming viral infections. However, the breakdown of resistance genes has been documented from many places where resistant cultivars have been developed. This has mainly been due to the emergence of resistance-breaking (RB) lines because of the consecutive use of these cultivars. The development of these isolates may cause great losses in both tomato and pepper plants in Türkiye. To investigate the incidence of TSWV, 150 symptomatic samples were …
A Phylogenetic Analysis And Delimitation Of Turanecio (Asteraceae: Senecioneae), Meryem Bozkurt, Tuna Uysal, Ergi̇n Hamzaoğlu
A Phylogenetic Analysis And Delimitation Of Turanecio (Asteraceae: Senecioneae), Meryem Bozkurt, Tuna Uysal, Ergi̇n Hamzaoğlu
Turkish Journal of Botany
Recently, Turanecio Hamzaoğlu was described as a new genus for the scientific world. Turanecio has been distributed as far as Asia, Iran, Caucasus, and Iraq. A phylogenetic analysis based on nrDNA and cpDNA gene regions was performed to determine the position of the genus within the subtribe Adenostylinae. Results from Bayesian and parsimony analyses of the nuclear and chloroplast DNA regions of the subtribe Senecioninae concordantly indicated that it is monophyletic and belongs to the Quadridentate group, with 4-lobed disc flowers. Nuclear DNA data revealed that some of the researched taxa should be transferred to Turanecio and some taxonomical classifications …

On The Border Of Extinction And Speciation, Polygala Seyfegoluensis (Polygalaceae), A New Species From Marshy Habitat, Central Türkiye: Under The Threat Of Climate Change, Water Retreat, And Subsequent Degradation, Ali̇ Aslan Dönmez, Zübeyde Uğurlu Aydin, İbrahi̇m Sirri Yüzbaşioğlu
Turkish Journal of Botany
Polygala seyfegoluensis Dönmez, Uğurlu & Yüzb. (Polygalaceae) is herein described and illustrated as a new species from Kırşehir Province around Seyfe Lake in Central Türkiye. This new species is similar to P. pruinosa and P. supina is distinctly characterized by its prostrate habit, nearly glabrous and smaller flower parts, and an unwinged capsule. A phylogenetic analysis was conducted to show the placement of the new species within selected Polygala taxa using the trnL-F and rbcL markers. Based on the field observation, an evolutionary scenario is proposed for the new species under the driving forces of climate change, the shrinking of …
