Turkish Journal of Botany

The study of viral diversity in uncultivated fungi, including those involved in mycorrhizal relationships, alongside research on viral communities in phytopathogenic and economically important fungi, is crucial for a comprehensive understanding of mycovirus diversity and evolution. Mycorrhizal fungi host various viruses, contributing to our understanding of virus diversity and evolution. Here, we report on the identification and complete genome characterization of two novel mitoviruses that naturally infect the hypogeous, mycorrhizal fungi Statesia pompholyx and Tuber sp. The identified viruses, denominated as “Statesia pompholyx mitovirus 1” (SpMV1) and Tuber mitovirus 3 (TruMV3), have genome lengths of 2549 and 3292 nucleotides and …

Benzothiadiazole Maintains Redox Balance And Promotes Defense Against Sitobion Avenae (F.) In Wheat By Fine-Tuning The Antioxidant System, Secondary Metabolism, And Osmolyte Accumulation., Fayyaz Ahmed, Samina Tanwir, Jam Nazeer Ahmad, Aysha Kiran, Faiz Ahmad Joyia

Turkish Journal of Botany

Aphids are destructive cereal pests causing serious yield losses in the wheat crop. Since wheat is a staple food for more than 75% of the human population, therefore, proper management of insect pests is crucial to enhance its productivity and ensure food security. Aphid herbivory induces highly coordinated defense responses in plants at the cellular and molecular level. This innate plant defense system is activated by a signal transduction pathway mediated by plant hormones like Salicyclic acid (SA). In the present investigation an attempt was made to explore the impacts of Benzothiadiazole (BTH), an analogue of SA on wheat plants …

Noccaea Bulutii (Brassicaceae): A New Species From Northeast Anatolia, Bariş Özüdoğru, Hayri̇ Duman

Turkish Journal of Botany

Noccaea bulutii is described as a new species from Artvin, in NE Anatolia. It resembles N. phyrgia, N. aptera, N. kovatsii and N. ochroleuca, but easily distinguished from all these species by its dentate basal leaves and elongated sterile shoots. Phylogenetic analyses using the nuclear-encoded ribosomal internal transcribed spacer (ITS) region placed N. bulutii and closely related species in a large polytomic clade, but none of these species formed a subclade with N. bulutii, demonstrating that these species are clearly distinct from each other. The species is described with diagnostic characters, detailed photographs, and taxonomic comments provided. The morphological similarities …

Effects Of Humic Acid And Salt Stress On Growth, Physiological Parameters And Mineral Substance Uptake In Artemisia Dracunculus L. (Tarragon), Serhat Seven, Şener Akinci

Turkish Journal of Botany

In this study, the physiological changes in Artemisia dracunculus L. plants under salinity stress and the remediative roles of leonardite-derived liquid humic acid (HA) were investigated. Salt stress caused a significant decrease in measured growth parameters (plant height, fresh weight of leaves and stems, dry weight of leaves and stems, number of leaves and leaf area). HA had a positive effect on growth parameters at 75 mM NaCl concentration, except for leaf number, but its effect was limited at 150 mM NaCl concentration. The total amount of protein was found to be lower in the leaves of seedlings grown under …
