Responses To Cadmium Stress In Two Tomato Genotypes Differing In Heavy Metal Accumulation, Shouping Zhao, Yongzhi Zhang, Xuezhu Ye, Qi Zhang, Wendan Xiao
Turkish Journal of Botany
Our previous research defined two tomato (Solanum lycopersicum) genotypes: high cadmium (Cd) accumulator YSL189 and low Cd accumulator HZ903. Further hydroponics experiments investigated the different tolerance mechanisms to Cd stress between YSL189 and HZ903 at the seedling stage. When Cd concentration was >20 µM in the growing medium, the uptake rate of Cd was significantly higher in roots of YSL189 than it was in roots of HZ903. When plants were supplied with 50 and 100 µM Cd in the growing medium, there were higher Cd concentration, higher biomass and plant height, shorter roots, and higher expression levels of transporter genes …

Analysis Of Interactions Of Nitric Oxide And Polyamine Under Cadmium Stress In Wheat, Fatma Mutlu, Füsun Yürekli̇
Turkish Journal of Botany
Wheat cultivars chosen for their cadmium (Cd) tolerance (Sönmez-2001) and sensitivity (Quality) were grown in Hoagland solution for 20 days and then they were treated with 100 μM 2-(4-carboxyphenyl)-4,4,5,5-tetramethylylimidazoline-1-oxyl (cPTIO), a nitric oxide (NO) scavenger, or with 100 μM sodium nitroprusside (SNP), a NO donor, with and without 9 mM Cd. NO, free polyamines, and Cd levels were analysed by using leaf and root samples taken 24 and 72 h after treatment. There was a significant increase in NO level in the Cd+SNP treatment in cv. Quality cultivars at 24 and 72 h. The NO level recorded in cv. Quality …

Expression Profiling Of Pap3, Bzip, And P5cs Genes In Soybean Underdrought Stress Conditions, Valiollah Soleimani, Jafar Ahmadi, Saber Golkari, Behzad Sadeghzadeh
Turkish Journal of Botany
Under drought stress, a signaling system induces the expression of specific genes to alleviate the harmful effects of drought stress. The BZIP gene is a transcription factor in the signaling abiotic stresses and plays a role in the regulation of responses to different stresses in plants. The P5CS gene controls the activity of the proline-5-carboxylate synthase enzyme that is involved in proline synthesis in drought stress conditions. In this research, the effect of drought stress was investigated on the expression of GmPAP3, GmBZIP and GmP5CS genes in two soybean cultivars, Williams (tolerant) and L17 (susceptible). Total RNA was isolated from …

In this study, the potential of Landoltia punctata for petroleum phytoremediation was evaluated. L. punctata was treated with different concentrations of Batman crude oil (BCO). The plants were grown in nutrient solutions containing 0.5%, 1%, 2%, and 3% BCO by volume in a growth chamber for 7 days. The fresh weight of the plants in the presence of BCO at a concentration of 0.5% v/v increased by 60% relative to the initial fresh weight. Furthermore, in comparison to the control, plant growth was retarded by 72% and 91% at concentrations of 2% and 3%, respectively. When plants were grown in …

This study describes and assesses the influence of the particular features of microhabitats on the abundances of lichen species. The research was performed in 4 natural reserves: Seaca-Movileni, Badeana, Harboanca-Brahaşoaia, and Balteni (all within Vaslui county). The distribution of lichen species abundances was investigated in 20 cm × 20 cm sampling units at a height of 1 m above the ground. In the studied area 27 lichen species were sampled in 81 sampling units. Cluster analysis indicated both similarities and dissimilarities between the natural reserves investigated. Kruskal-Wallis tests pointed out significant differences regarding tree girths, depth of rhytidome crevices, and …
Do Epidermal Cell Types Have An Effect Upon Ultraviolet Patterns On Flower Petals?,

Do Epidermal Cell Types Have An Effect Upon Ultraviolet Patterns On Flower Petals?, Margaux Flaherty
Williams Honors College, Honors Research Projects
Flower petal epidermal cell shape and ultraviolet patterns called nectar guides may have a considerable impact on pollinator behavior and consequently, the reproductive success of the floral species. Similarly, flower petal epidermal cell shape may have an effect on floral color; however, these effects have only been measured in the visible light range (Whitney et al., 2009). This study attempts to determine if epidermal cell shape has an effect upon ultraviolet floral patterns. Experimental results show that all of the floral species studied seem to have a conical epidermal cell shape, but varying levels of ultraviolet reflectance and absorbance; …

A Comparison Of Management Strategies For The Federally Endangered Running Buffalo Clover (Trifolium Stoloniferum) On The Blue Grass Army Depot, Ky, Alexi David Dart-Padover
Online Theses and Dissertations
Running buffalo clover (Trifolium stoloniferum) is a federally endangered plant that appears to depend on habitat disturbance, although proposed management strategies such as cattle grazing, mowing, and herbicide application have never been compared in a controlled study. We evaluate the efficacy of these techniques on the Blue Grass Army Depot (BGAD) in Madison County, KY, where one of T. stoloniferum’s largest populations occurs. Fifty-nine patches of T. stoloniferum on the BGAD were treated annually between 2012 and 2014 with combinations of mowing and grass-specific herbicide. Patches of T. stoloniferum also were exposed to one of three types of cattle exposure …
Alleviation Of Photosynthetic Inhibition In Copper-Stressed Tomatoes Through Rebalance Of Ion Content By Exogenous Nitric Oxide, Lina Wang, Xiaoyu Yang, Zhonghai Ren, Xiangyang Hu, Xiufeng Wang
Turkish Journal of Botany
Copper (Cu) is an essential element that plays a very important role in plant growth and development. Its accumulation in soil is now considered a serious environmental problem endangering agricultural production and human health. In this study, the influence of exogenous nitric oxide (NO) on photosynthesis, Cu, magnesium (Mg), and iron (Fe) contents was studied in tomato seedlings under Cu stress grown in hydroponic culture. The results showed that the addition of sodium nitroprusside (SNP), a donor of exogenous NO, significantly alleviated photosynthetic inhibition in Cu-stressed tomatoes, including the recovery of photosynthetic pigment content and chlorophyll a fluorescence and the …

Effects Of Benzyladenine Purine And Its Interaction With Polyamines On Growth Of Spathoglottis Plicata Plbs, Zaliyatun Akhma Mat Yasin, Maziah Mahmood, Noor Azmi Shaharuddin
Turkish Journal of Botany
Spathoglottis plicata is highly sought after by florists and orchid growers due to its unique structure and colors. However, this orchid is a slow-growing type and thus the planting materials are acutely limited. Therefore, there is a need to improve its multiplication efficiency and speed up its growth in order to meet the market demand. Benzyladenine purine (BAP) has been widely used to improve plantlet multiplication in plant cultures. Polyamines have also been reported to improve the growth and development of in vitro cultures. The objective of this study was to investigate the effects of BAP and different polyamines on …

Sisymbrium malatyanum Mutlu & Karakuş is identified as a new species from Malatya Province, East Anatolia, Turkey. Morphological and molecular (entire ITS region) studies proved that this species especially resembles Sisymbrium brassiciforme, S. heteromallum, S. altissimum, S. damascenum, and S. austriacum subsp. contortum. New species and related taxa are discussed in terms of morphological and molecular differences. Epicuticular wax on the fruit surface of the new species was determined. SEM images (hairs on leaf, stem, fruit, stylus, and epicuticular wax crystalloids) and field photographs (habitat, flowering and fruiting shape of habitus, and fruit) are presented.

The taxa of the genus Euphorbia L. Have seeds that mature in schizocarp fruits, called cocci, with three or more cells, each of which explosively splits open into separate parts at maturity. The Euphorbia seeds have taxonomically useful characters. We studied 13 taxa of the genus Euphorbia distributed in Turkey-in-Europe, with a focus on the seed characters; for morphological observations we used a stereomicroscope, and for surface microstructure we used a scanning electron microscope (SEM). The morphological observations showed that the seed characters of shape, size, color, surface features, and the features of the caruncle are uniquely different. SEM observations …
