Bioinformatics Profiling And Characterization Of Potentialmicrornas And Their Targets In The Genus Coffea, Farzana Bibi, Muhammad Younas Khan Barozai, Muhammad Din

Turkish Journal of Agriculture and Forestry

MicroRNAs (miRNAs) are a class of noncoding small endogenous RNAs with lengths of 18 to 26 nucleotides that have been shown to regulate gene expression at posttranscriptional levels by targeting mRNAs for degradation or by inhibiting protein translation. Although thousands of miRNAs have been identified in many species, limited miRNAs have been reported in the genus Coffea, a member of the family Rubiaceae that is endemic to tropical Asia and South Africa. The genus Coffea, whose seeds are known as coffee beans, is used to make coffee. In this study, we identified 51 potential genus Coffea miRNAs, belonging to 51 …

Turkish Journal of Agriculture and Forestry

Pokeweed antiviral protein (PAP) of Phytolacca americana L. (pokeweed) is a single-chain ribosome-inactivating protein (RIP) characterized by its ability to depurinate plant ribosomes. Here, we isolated, cloned, and expressed the ribosome inactivating protein (RIP) gene, designated as pokeweed antiviral protein type 1 (PAP I), from the summer leaves of pokeweed collected from the Black Sea region (Turkey). Our findings presented here provide direct evidence that exogenous application of PAP I causes concentration-dependent inhibition of Zucchini yellow mosaic virus (ZYMV) infection on squash plants. Squash plants were exposed to PAP I protein with and without DMSO for four consecutive days. Regular …

In Vitro Production Protocol Of Vaccinium Uliginosum L. (Bog Bilberry)Growing In The Turkish Flora, Mustafa Cüce, Atalay Sökmen

Turkish Journal of Agriculture and Forestry

This novel approach was designed to increase the production capacity of Vaccinium uliginosum L. via direct organogenesis. Lateral buds containing one or two leaves were initially cultured in McCown woody plant medium (WPM), Anderson's rhododendron medium, and Murashige and Skoog basal media, each supplemented with zeatin/indole-3-butyric acid (IBA) and zeatin/naphthalene acetic acid (NAA) (1.0/0.1 mg L-1). WPM containing the zeatin/IBA combination was the most effective as the basal medium. Various plant growth regulators (PGRs) were then investigated for the best shoot multiplication, and zeatin was found to be most favorable PGR in all cases. The highest shoot length and shoot …

The results showed that chip size had a significant effect on the chemical properties of hydrothermally treated wood under pressure in hot water. As chip size was …

Afforestation Of Arid And Semiarid Ecosystems In Turkey, Servet Çalişkan, Meli̇h Boydak

Turkish Journal of Agriculture and Forestry

Sustainable management of arid and semiarid forests requires careful planning and implementation. Afforestation by planting and seeding is a fundamental tool for the establishment of new forests on barren landscapes and restoration of degraded forests in arid and semiarid ecosystems. In afforestation efforts, the consideration of site preparation, selection of species, seed source, and planting methods pose a number of ecological and economic challenges. Possessing one of the world's richest floras, Turkey suffered from heavy degradation during the last millennia. Some studies suggested that forests and steppes once covered 60%-70% and 10%-15% of the Anatolian landscape, respectively. Growing population, overgrazing, …

Inoculation With Bacillus Licheniformis Mh48 To Improve Camellia Japonicaseedling Development In Coastal Lands, Hyun-Gyu Park, Min-Hae Jeong, Young-Sang Ahn

Turkish Journal of Agriculture and Forestry

This study aimed to determine the promotion of the growth and nutrient uptake of Camellia japonica seedlings in coastal lands by bacterial inoculation. Soil salinity reduces plant growth and development in coastal areas due to the osmotic stress that perturbs nutrient uptake. The soil electrical conductivity at the sites of this study ranged from 1.02 to 1.89 dS m-1. Application of chemical fertilizer resulted in the limited uptake of nutrients in seedlings under saline conditions as well as a low nutrient content in the soil caused by leaching, with no significant influence on the growth of the seedlings. However, Bacillus …

Antioxidant Capacity Of Oilseed Rape (Brassica Napus) In Different Soil Types, Dusica Jovicic, Jovica Vasin, Zorica Nikolic, Gordana Petrovic, Gordana Tamindzic, Maja Ignjatov, Dragana Milosevic

Turkish Journal of Agriculture and Forestry

This work considers the results obtained by testing the parameters of antioxidant status in leaves and roots of oilseed rape at different growth stages (phase I: formation of leaf rosettes and preparing for winter hibernation; phase II: after the winter hibernation; phase III: flowering) grown in semicontrolled field conditions on different soil types. The experiment was conducted on four oilseed rape genotypes (Banacanka, Jasna, Kata, and Zlatna) in semicontrolled conditions in containers with three soil types: chernozem, solonetz, and solonchak. The germination failed on solonchak due to the excessive amount of salt, but results were obtained for plant material on …

Use Of Snp Markers By Kasp Assay For Mas Studies In Sunflower Againstplasmopara Halstedii, Kevser Kösoğlu, Sevcan Yumuk, Yildiz Aydin, Göksel Evci̇, Ahu Altinkut Uncuoğlu

Turkish Journal of Agriculture and Forestry

Downy mildew is a fungal disease caused by Plasmopara halstedii and leads to loss of yield up to 100% in sunflower. Disease control is performed mostly through chemical seed treatment and breeding. Due to the time consuming nature of conventional breeding, it is supported by biotechnological approaches. Marker-assisted selection (MAS) is a strategic approach in molecular breeding using molecular markers. Single nucleotide polymorphisms (SNPs) such as insertions, deletions, and base-pair substitutions are more advantageous than other molecular markers. The abundance and biallelic nature of SNPs in a genome provide flexibility in the choosing of SNPs at the desired loci. Competitive …

Establishment Of American Chestnuts On Surface Mined Lands In Appalachian Coalfields Region, Michael E. French

Theses and Dissertations--Forestry and Natural Resources

American chestnut (Castanea dentata (Marsh.) Borkh.) was an dominant hardwood throughout eastern North America until the introduction of an exotic fungus (Cryphonectria parasitica (Murr.) Barr) in the early 20^th century devastated American chestnut populations. Chestnuts that have been bred for blight resistance have recently become available for testing. Due to the overlap of American chestnut’s natural range and the Appalachian coalfields region, the potential establishment of founder populations of blight-resistant chestnuts on reclaimed coal surface mines has recently gained attention. This work examined chestnut establishment on a surface mine in eastern Kentucky to assess factors controlling early …

Roosting Behavior, Habitat Use, And Relative Abundance Of The Northern Long-Eared Bat (Myotis Septentrionalis) Following Arrival Of White-Nose Syndrome To Mammoth Cave National Park, Marissa M. Thalken

Theses and Dissertations--Forestry and Natural Resources

White-Nose Syndrome (WNS; Pseudogymnoascus destructans) is responsible for the regional population collapse of many cave-hibernating bat species, including the northern long-eared bat (Myotis septentrionalis), in eastern United States and Canada. I evaluated roosting behavior, habitat selection, and landscape-scale distribution of roosts of the northern long-eared bat during spring emergence and the early maternity season in Mammoth Cave National Park, Kentucky, USA, from 2015 to 2016. Logistic regression analysis comparing habitat features of roosts with random plots indicated selection of roosts reflected the costs of energetic demands by sex and reproductive status. Relative abundance of local bat species …

Managing Upland Oak Forests With Disturbance And The Implications For Non-Native Species Invasions, Devin E. Black

Theses and Dissertations--Forestry and Natural Resources

Natural and anthropogenic disturbances have influenced forest stand structure and affected species compositions within forests for millennia. Disturbances such as fire, severe weather events, and forest management practices may result in significantly reduced tree biomass. Thus, these disturbances may lower canopy closure and stem density in support of forest management goals, such as open oak woodland restoration, or promote an increase in species richness within the forest understory. However, these types of disturbance may also produce the unwanted consequence of opening pathways for the invasion of non-native species. Once established, these non-native species may threaten native plant communities and biodiversity. …

An Investigation Of Tree Growth And Woody Vegetation Colonization On A 19 Year-Old Forestry Reclamation Site, Wesley T. Dement

Theses and Dissertations--Forestry and Natural Resources

Survival, growth and biomass accumulation of 19 year-old trees planted on an Appalachian surface mine site were evaluated to determine the effect of spoil grading and surface amendment treatments. Three spoil grading treatments (loose-dump, strike-off and graded control) were established to create a range of operationally feasible spoil compaction capable of impacting tree establishment and growth. Likewise, three surface amendment treatments (straw/manure mulch, hardwood bark mulch and control) were applied to determine their effects on tree development. Trees grown under low-compaction grading treatment levels (strike-off and loose-dump) consistently outperformed trees planted in a high-compaction control treatment. Loose-dump preparation resulted in …

Survival And Cause-Specific Mortality Of A Southeastern Kentucky Deer Population, Caleb Anderson Haymes

Theses and Dissertations--Forestry and Natural Resources

White-tailed deer are one of the most sought after game species in Kentucky. While much of the Commonwealth boasts high deer populations, those in southeast Kentucky are viewed as relatively low compared to other regions, even after a decade of restrictive doe harvest and multiple years of population supplementation via translocation. We studied survival and cause specific mortality of a local population of deer near the Redbird District of the Daniel Boone National Forest in Clay and Leslie County, Kentucky from January 2014 - January 2017. We estimated female annual survival at 0.89 (CI: 0.88-0.87), with an overall 3-year survival …

Information Technology Approaches To Forest Management, Mary Snow, Richard Snow

Publications

The majority of the world’s forests occur where there is a dry season long enough to affect a seasonal change in the forest community. The seasonal forest may include evergreen, semi-deciduous, deciduous trees, or some combination of these. Local differences in soil or other site characteristics often determine which community persists. Since the seasonal forests exist where there is seasonal precipitation, the character of the forest is closely associated with the length of the rainy season. As the length of the rainy season decreases, the density of the canopy decreases. If the global climate system warms and prolonged drought gives …

Are Weevils Picky Eaters? Community Structure And Host Specificity Of Neotropical Saproxylic Beetles (Coleoptera: Curculionidae), Jhunior A. Morillo

Dissertations and Theses

Abstract Primary saproxylic beetles play a major role in forest nutrient cycling and making deadwood accessible to other decomposers. Understanding beetle host preferences and patterns of community assembly is critical for their conservation, and for predicting which species might become invasive. This project aims to investigate the ecological and host specificity, as well as the community composition of curculionids in a mosaic of old-growth (OG) and secondary forest on the Osa Peninsula, Costa Rica. The subfamily Scolytinae was expected to be the most species-rich and abundant. Ambrosia beetles were expected to have more generalist species than other curculionids. Old growth …

Do Dynamic Global Vegetation Models Capture The Seasonality Of Carbon Fluxes In The Amazon Basin? A Data-Model Intercomparison, Natalia Restrepo-Coupe, Naomi M. Levine, Bradley O. Christoffersen, Loren P. Albert, Jin Wu, Marcos H. Costa, David Galbraith, Hewlley Imbuzeiro, Giordane Martins, Alessandro C. Da Araujo

School of Integrative Biological & Chemical Sciences Faculty Publications

To predict forest response to long-term climate change with high confidence requires that dynamic global vegetation models (DGVMs) be successfully tested against ecosystem response to short-term variations in environmental drivers, including regular seasonal patterns. Here, we used an integrated dataset from four forests in the Brasil flux network, spanning a range of dry-season intensities and lengths, to determine how well four state-of-the-art models (IBIS, ED2, JULES, and CLM3.5) simulated the seasonality of carbon exchanges in Amazonian tropical forests. We found that most DGVMs poorly represented the annual cycle of gross primary productivity (GPP), of photosynthetic capacity (Pc), and of other …

The Effect Of Chronic Nutrient Addition From Wastewater On Forest Ecosystems At The Rice Rivers Center, Michael Beck

Theses and Dissertations

Wastewater application to land can be a useful tool for mitigating impacts of nutrient enrichment on aquatic systems. A land application treatment system at VCU’s Rice Rivers Center in Charles City County, VA provided an opportunity to study the impact of wastewater addition on the biogeochemistry of forests representative of the Mid-Atlantic Coastal Plain. Nutrient concentrations in throughfall and leachate were measured at Treatment and Control sites to assess differences in nutrient deposition and retention. Wastewater amended plots from the Walter L. Rice education building received 20-fold (N) and 6-fold (P) higher inputs relative to Control plots and plots located …
