Betalains And Expression Of Antioxidant Enzymes During Development Andabiotic Stress In Rivina Humilis L. Berries, Mohammad Imtiyaj Khan, Avinash Kumar, Parvatam Giridhar

Turkish Journal of Botany

This work investigated the betalains profile and associated molecular changes during Rivina humilis L. Berry development and 1 month after inducing stress through elicitors such as salicylic acid (SA, 0.05-0.5 mM) and chitosan (CH, 0.1%-1.0%). The results showed that, during berry development, diphenol oxidase activity of tyrosinase increased, which was reflected in an exponential increase in betalains accumulation. Expression levels of a putative Rivina humilis betanidin-5-O-glucosyltransferase 2 (RhBGT2) remained unchanged, while that of antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT) decreased. Treatment with SA (0.1 mM) and CH (0.5%) enhanced betalains accumulation. The pattern of betalains accumulation during berry …

Cladonia Trapezuntica (Cladoniaceae, Lichenized Ascomycota): A Robust Morphotype Of Pycnothelia Papillaria, A Taxonomic Study With Conservational Survey, Ayhan Şenkardeşler, Demet Cansaran Duman, Laszlo Lökös, Teuvo Ahti

Turkish Journal of Botany

The long-neglected lichen described as Cladonia trapezuntica was rediscovered at its type locality in Turkey thanks to historical maps available at the Natural History Museum in Vienna. Molecular, morphological, and chemical analyses were applied to determine whether C. Trapezuntica is a distinct species or rather falls within the phenotypic variation of Pycnothelia papillaria. Although most of the podetia appear to be unusual for P. Papillaria, the molecular evidence indicates that C. Trapezuntica should be considered as a synonym of P. Papillaria, and the cushion-like growth form, taller podetia with irregular to dichotomously or trichotomously branching pattern, and scarce primary thallus …

Tulostoma Ahmadii Sp. Nov. And T. Squamosum From Pakistan, Shah Hussain, Nousheen Yousaf, Najam-Ul-Sehar Afshan, Abdul Rehman Niazi, Habib Ahmad, Abdul Nasir Khalid

Turkish Journal of Botany

Tulostoma ahmadii, a new species found in the subtropical pine forest of Malakand, Pakistan, is described and illustrated. It is characterized by parallel to squamulose deep reddish brown scales on stipe with bulbous base, warty exoperidium, and tubular and relatively large-sized basidiospores. Macro- and microscopic features along with sequence data demonstrated that Tulostoma ahmadii is a distinct species from other members of Tulostoma. T. Squamosum, which is represented here as a new record for the country, has also been characterized on a molecular basis.

Ecological Wood Anatomy Of Fraxinus L. In Turkey (Oleaceae): Intraspecific And Interspecific Variation, Funda Erşen-Bak, Nesi̇me Merev

Turkish Journal of Botany

Wood anatomy features of eight taxa (four species) of the genus Fraxinus L. indigenous to Turkey were examined. Wood samples were collected from different altitudes of their natural growth areas. Data were gathered on quantitative anatomical features such as tangential and radial vessel diameters, number of vessels per mm2, length of vessel elements, fibers (lengths, widths, thickness of cell walls, lumen diameters), number of rays per mm, and ray width and height. By using vessel member features, the vulnerability ratio (vessel diameter divided by number of vessels per mm2) and mesomorphy value (vulnerability ratio multiplied by vessel elements length) were …

Labellum Micromorphology Of Some Orchid Genera (Orchidaceae) Distributed In The Black Sea Region In Turkey, Şenay Süngü Şeker, Mustafa Kemal Akbulut, Gülcan Şenel

Turkish Journal of Botany

A detailed micromorphological analysis of the labellum was carried out using both light and scanning electron microscopy on 14 genera (Anacamptis, Cephalanthera, Coeloglossum, Dactylorhiza, Gymnadenia, Himantoglossum, Limodorum, Neottia, Orchis, Ophrys, Platanthera, Serapias, Spiranthes, and Steveniella) of Orchidaceae in Turkey. In the samples, various epidermal features were identified in the spur that developmentally are invaginations of the labellum and the adaxial surface of the labellum. Typical secretory cells and inclusions such as starch or calcium oxalate crystals of different sizes and shapes were found within the structure of individuals. In many genera, characteristically shaped secretory trichomes and papillae were concentrated at …

The Effects Of Simulated Herbivory On The Growth Of Wisconsin Fast Plants, Jessica Joerger, Tanner Logan, Kiefer Kious, Jake Rancic

Celebration of Learning

Wisconsin Fast Plant (Brassica rapa, Brassicaceae) seeds were planted in three six-celled containers with 15 seeds in each tray. After a week of germination in standard potting soil and tap water,

we started our manipulation of simulating herbivory with scissors. E1 plants had both cotyledons of each plant removed, E2 plants had half of the cotyledons of each plant removed, and the control group was allowed to grow. E2 plants had its foliage leaves cut when they exceeded 1 cm from that week on. Every week (seven-day intervals), the height of all the plants were recorded as well as the …

Exogenous Nitric Oxide Protects Against Drought-Induced Oxidativestress In Malus Rootstocks, Linsen Zhang, Xuewei Li, Xifeng Li, Zhou Wei, Mingyu Han, Lixin Zhang, Bingzhi Li

Turkish Journal of Botany

D?rought is a major environmental stress that limits the growth and productivity of fruit trees in semiarid and arid regions. We evaluated the potential of exogenous nitric oxide (NO) to improve the drought tolerance of apple rootstocks (Malus spp.). Leaves of 2-year-old seedlings of drought-sensitive Malus hupehensis (Pamp.) Rehd. And drought-tolerant Malus sieversii (Ledeb.) M.Roem. Rootstocks were sprayed with NO donor sodium nitroprusside (SNP) at 0-400 μmol L-1, and then the plants were subjected to drought stress. Among all SNP treatments, the 300 μmol L-1 SNP treatment mostly alleviated drought-induced ion leakage and the accumulation of malondialdehyde and solu?ble proteins …

Effects Of Elevated Co2 And Nutrients On The Community Metabolism Of A Cymodocea Nodosa Bed, Faisal Khan, Ana Alexandre, Hadayet Ullah, Rui Santos

Turkish Journal of Botany

We assessed the combined effects of elevated CO2 and nutrients on the metabolism of a benthic community dominated by the seagrass Cymodocea nodosa (Ucria) Ascherson in a mesocosm experiment. C. Nodosa plants and their associated community were exposed to two CO2 levels simulating future (700 ppm, pH 7.84) and current (360 ppm, pH 8.12) conditions, and two nutrient levels (enriched and ambient concentration) in a total of four treatments (-C-N, -C+N, +C-N, +C+N). Net community production (NCP) was estimated from changes in the concentration of dissolved inorganic carbon in the seawater in light incubations using benthic chambers. The variation pattern …
