Cloning Of Lipase Cdna From Olea Europaea Cv. Gemlik Leaves And Expression Analysis Inresponse To Cold Stress, Muni̇se Yurtsever, Şenay Vural Korkut

Turkish Journal of Botany

The cDNA encoding lipase enzyme was cloned from Olea europaea var. europaea cv. Gemlik leaves using the RACE method. The full nucleotide sequence was 1546 bp long and encoded a putative protein of 412 amino acid long protein. The amino acid sequence showed identity to Triacylglycerol Lipase 1 sequences from different plants. A phylogenetic tree was constructed showing relations with various plant lipases. Multiple sequence alignment analysis of the putative protein sequence revealed that the enzyme contains conserved GXSXG pentapeptide motif, and the catalytic triad was predicted as Ser-182, His-379, and Asp-350 with bioinformatics tools. Real-time PCR was used to …

Turkish Journal of Botany

The objective of this study was to assess morphological and genetic diversities of 48 forage pea landraces collected from different locations at different altitudes in Turkey. Morphological, quality, and yield features were determined for the landraces and three control cultivars in three subsequent years. Genetic diversities of the landraces and cultivars were also monitored using microsatellite (SSR) markers. Our results revealed that the features of landraces are significantly different. The hay weights and the relative feed values were found to be significantly affected by altitude, with the landraces generally showing significantly higher hay weight and relative feed values at lower …

Epiphytic Diatoms As Bioindicators Of Trophic Status Of Lake Modrac(Bosnia And Herzegovina), Jasmina Kamberovi?, Vedran Stuhli, Zorana Luki?, Mirela Habibovic, Emina Me?Iki?

Turkish Journal of Botany

Biodiversity of diatoms and applicability of diatom indices in biomonitoring based on littoral epiphytic samples of Lake Modrac were investigated. Diatoms were taken mostly from Phragmites australis stems in 2017, during which physical and chemical parameters of the water were measured. A total of 85 diatom taxa were identified. Gomphonema (13 spp.), Navicula (11 spp.), and Nitzschia (8 spp.) were the most abundant genera. Obtained values of trophic indices (TID, TvD, and TDIL) pointed to meso- to eutrophic status for most localities, while values of the IBD, EPI, ?D, and IPS indices indicated good ecological status, except for localities at …

Syntaxonomic Analysis Of Forests, Shrubs, And Steppes Of Tavşan Mountain(Amasya, Turkey), Cengi̇z Yildirim, Erkan Yalçin, Arzu Cansaran, Hasan Korkmaz

Turkish Journal of Botany

The aim of this study is to reveal the syntaxonomical structure of Tavşan Mountain in the Euxinian transition area in northern Turkey. Eight plant associations were determined and classified using the Braun?Blanquet phytosociological approach. Detrended correspondence analysis was also used to reveal the environmental heterogeneity among the plant associations. Raunkiaer life form ratios of syntaxa were calculated. Shannon?Wiener index values also were determined for each plant association. The results of this study suggested that which environmental factors could be decisive in community diversity and syntaxonomical status.

A Multiple Epidermis Or A Periderm In Parkinsonia Praecox (Fabaceae), Silvia Aguilar-Rodriguez, Teresa Terrazas, Xicotencatl Camacho-Coronel

Turkish Journal of Botany

A multiple epidermis in the green stems of Parkinsonia species has been described; however, there are disagreements among authors with regard to origin and tissues involved. The aims of this study were to identify the origin and development of the epidermis and cortex of P. praecox and relate these to possible adaptations to arid environments. Samples from new branches, to the stem, were removed and prepared using two embedding techniques. Our results show that the epidermis is simple, but periclinal divisions start far from the apical meristem. The inner derivatives maintained periclinal and anticlinal divisions, which are interpreted as meristematic, …

Department of Agronomy and Horticulture: Faculty Publications

Nitrogen provided to crops through mineralization is an important factor in N management guidelines. Understanding of the interactive effects of soil and weather conditions on N mineralization needs to be improved. Relationships between anaerobic potentially mineralizable N (PMN_an) and soil and weather conditions were evaluated under the contrasting climates of eight US Midwestern states. Soil was sampled (0–30 cm) for PMN_an analysis before pre-plant N application (PP_0N) and at the V5 development stage from the pre-plant 0 (V5_0N) and 180 kg N ha−1 (V5_180N) rates and incubated for 7, 14, and …

Thiamin-Induced Variations In Oxidative Defense Processes In White Clover(Trifolium Repens L.) Under Water Deficit Stress, Adeel Ghaffar, Nudrat Aisha Akram, Muhammad Ashraf, Yasin Ashraf, Muhammad Sadiq

Turkish Journal of Botany

Vitamins are regarded as vital growth substances. They act as cofactors of various key enzymes involved in metabolism and also have vital influence on metabolic activities of plants. They are believed to play a significant role in plants against abiotic stresses, particularly during water stress. The current experiment was conducted to evaluate the role of exogenously applied thiamin on two white clover cultivars, Super Late Fsd and Layalpur Late, at varying [100% (control), 80%, and 60% field capacities] water regimes. A significant suppression was noted in plant biomass, plant height, chlorophyll a and b contents, total soluble proteins, and shoot …

Turkish Journal of Botany

Proso millet (Panicum miliaceum L.) has many favored nutritional and agronomic traits, which makes it appropriate for cultivation and consumption all around the world. Genomic resources for proso millet are still very limited but the set of genomic data is improving. In this study, we genotyped six Slovenian landraces of proso millet (P. miliaceum L.) along with one Slovene autochthonous cultivar, Son?ek. The chosen set of 11 SSR markers showed that there is low overall heterozygosity (0.561) among Slovenian landraces of proso millet. However, we were able to determine distinct groups on the dendrogram for different landraces and the cultivar …

Cellular Patterns And Metabolic Changes During Tepal Development In Lilium Tsingtauense, Jiang Xinqiang, Chi Xiufeng, Li Wei, Wang Jianping, Liu Qingchao, Wang Kuiling, Liu Qinghua

Turkish Journal of Botany

Lilium tsingtauense is an endangered bulb plant in China that has curved leaves and orange flowers. Little is known about the opening of the L. tsingtauense flower. In this paper, the blooming process of L. tsingtauense flowers was sampled in five stages according to characteristic tepal morphology. The center of the tepal has an increasing elongation rate compared with the upper and lower parts. Tepal growth from closed buds at the greenish tepal stage (CBS) to the completely opened buds at the horizontal tepal stage is mainly due to cell division, cell elongation, and obvious longitudinal cellular growth. The fructose …

Natural And Anthropic Forest Fragments Have Distinct Ecological Behavior Due To Their Different Origin And Landscape Context, Cleber Souza, Polyanne Coelho, Paola Ferreira Santos, Gisele Cristina De Oliveira Menino, Jean Morel, Aline Moreira, Rubens Manoel Dos Santos

Turkish Journal of Botany

We tested the hypothesis that plant populations in natural fragments have distinct ecological behavior in relation to anthropic fragments. We selected the species Myrcia splendens (SW.) DC. in 2 forest fragments located in southeastern Brazil that present different origins and landscape contexts. The natural fragment originates from landscape relief variations and is inserted in a native grassland matrix, while the anthropic fragment originates from fragmentation due to area conversion and is inserted in an agricultural matrix. We established transects covering an area from one border to the other in each fragment, and we established subunits of 400 m2 within them. …

Turkish Journal of Botany

Centaurea uysalii Şirin & Çeçen, a new Asteraceae species from the province of Karaman, in Turkey, is described and illustrated herein. It is morphologically similar to C. bourgaei Boiss. (Subgen. Cyanus), but it mainly differs from its relative in terms of the involucre and achene lengths. The achene micromorphological features and karyomorphology of C. uysalii and C. bourgaei were examined in this study. The IUCN conservation status is the Critically Endangered [CR B2 a b (i, iii)] category.

Manfreda Maculosa Leaf Extracts And Their Effects On Whole And Selected Myotoxic Components In Crotalid Venom, Charles Steven Gilbert

Open Access Theses & Dissertations

Manfreda spp have been used for the treatment of snakebite by several cultures in North and Central America (Austin & Honychurch, 2004, Johnson, 1999, Moerman, 2008, Verhoek, 1978a). There has been no systematic study of the genus Manfreda for its usefulness in the treatment of snakebite.

While the annual incidence of snakebite in the United States is relatively low (approximately 8,000 - 10,000), with a low mortality rate of 5 - 6 cases per year, there is still significant morbidity associated with snakebite (CDC - NIOSH, 2018, Springhouse Corp (eds), 2005). Worldwide numbers of the cases of snakebite can only …

Seaweed Community Structure Along Environmental Gradients In An Ocean-Dominated Estuary, Saskia A. Raether

Cal Poly Humboldt theses and projects

Macrophyte community structure in estuaries that have been modified by the addition of hard substrata are poorly documented, especially in relation to the physical and environmental gradients that shape them. Therefore, this study describes the summer macrophyte flora that occurs on hard and soft substrata throughout Humboldt Bay, CA and tests how the macrophyte communities correlate to measures of horizontal and vertical environmental gradients. The percent cover of macroalgae, vascular plants, cyanobacteria, lichens, diatom film, sessile invertebrates, and substratum types were quantified during the summers of 2017 and 2018 at eleven intertidal locations in the bay and outer coast. Horizontal …

Ectomycorrhizal Fungal Community Assembly On Seedlings Of A Neotropical Monodominant Tree, Carolyn Delevich

Cal Poly Humboldt theses and projects

Formation of ectomycorrhizae may facilitate early seedling survival of ectomycorrhizal tree species due to enhanced nutrient acquisition. This could be especially important in heavily shaded understories of tropical monodominant forests where host plant photosynthetic capacity is limited. Little information is available on ectomycorrhizal (ECM) fungal colonization or community development of monodominant seedling cohorts, which have high survival rates. Following a 2016 mast seeding event, we sequentially measured percent colonization and species composition of ECM fungi on live and recently dead seedlings of the tropical monodominant tree Dicymbe corymbosa. We also compared seedling ECM fungi to those of nearby adult …
