Year-End Report On Rac Project Entitled "Propagating Aspen Clones: Survival In The 21st Century", Ralph Baierlein

Aspen Bibliography

Initial damage caused by wild ungulates was minimal. In August 2013, a large elk pulled off five cones and destroyed three saplings on the exposed, eastern side of the exclosure. Although deer tracks were plentiful in the bare earth of the fire line, there was no evidence that deer had harmed the saplings. The combination of a cone and a mesh sleeve on the exposed saplings sufficed.

Understanding Farmers’ Perceptions And The Effects Of Shea Tree Vitellaria Paradoxa Distribution In Agroforestry Parklands Of The Upper West Region, Ghana, Fahimeh Baziari

Dissertations, Master's Theses and Master's Reports - Open

Agroforestry parklands represent a vast majority of the agricultural landscape under subsistent-oriented farming in semi-arid West Africa. Parklands are characterized by the growth of well- maintained trees (e.g., shea) on cultivated fields as a result of both environmental and human influences. Shea (Vitellaria paradoxa) provides a cultural and economic benefit to the local people of Ghana, especially women. Periods between traditional fallow rotation systems have reduced recently due to agricultural development and a demand for higher production. As a result, shea trees, which regenerate during fallow periods, has decreased over the landscape. The aim of this study was …

Generation Of Transgenic Sugar Beet (Beta Vulgarism L.) Overexpressing The Polygalacturonase Inhibiting Protein 1 Of Phaseolus Vulgaris (Pvpgip1) Through Agrobacterium-Mediated Transformation, Reza Mohammadzadeh, Mostafa Motallebi, Mohamadreza Zamani, Zahra Moghaddassi Jahromi, Peyman Norouzi, Manuel Benedetti, Giulia De Lorenzo

Turkish Journal of Agriculture and Forestry

Numerous diseases caused by fungal pathogens influence the annual production of sugar beet. In order to obtain a plant resistant to fungi, genetic transformation has been applied to the sugar beet. To invade a plant tissue, phytopathogenic fungi produce several cell wall-degrading enzymes (CWDEs); polygalacturonases (PGs) are pathogenicity factors produced at the earlier stages of a fungal infection that depolymerize the homogalacturonan. One of the strategies used by plants to limit the degradation of the cell wall polysaccharides by fungal CWDEs is the production of proteinaceous inhibitors. Against fungal, microbial, and insect PGs, plants produce cell wall-associated polygalacturonase-inhibiting proteins (PGIPs). …

Genetic Variability, Heritability, And Genetic Advance In Strawberry(Fragaria × Ananassa Duch.), Pranav Kumar Mishra, Ram Badan Ram, Neeraj Kumar

Turkish Journal of Agriculture and Forestry

Strawberry (Fragaria × ananassa Duch.) genotypes were evaluated to study genetic variation and the relationship between yield and its component using a randomized complete block design during 2013/14. The results showed significant variance among genotypes of all traits. The phenotypic coefficient of variation (PCV) for all the characters was slightly higher than genotypic coefficient of variation (GCV), which signified the presence of environmental influence to some degree in the phenotypic expression of characters. Dry fruit weight had the highest PCV (52.47) and GCV (48.26). The estimates of narrow sense heritability (h2) were observed to be lower than those of broad …

Identification And Functional Annotation Of Expressed Sequencetags Based Ssr Markers Of Stevia Rebaudiana, Rajinder Kaur, Neha Sharma, Ravinder Raina

Turkish Journal of Agriculture and Forestry

Stevia rebaudiana Bertoni, a perennial herb belonging to the family Asteraceae, is a tropical as well as subtropical plant of medicinal importance. Despite being an important medicinal plant and in fact proving a boon to diabetics, it has remained almost ignored by molecular biologists. A systematic molecular evaluation of stevia germplasm and molecular breeding work are sparsely reported mainly due to the limited specific molecular markers available. Expressed sequence tags (ESTs) are a valuable resource for developing simple sequence repeats (SSRs). In this study, 5548 stevia ESTs sequences from leaf tissues were retrieved from the NCBI database. Clustering and assembly …

Single Nucleotide Polymorphism Discovery Through Illumina-Based Transcriptome Sequencing And Mapping In Lentil, Hülya Yilmaz Temel, Deni̇z Göl, Hi̇lal Betül Kaya Akkale, Abdullah Kahri̇man, Muhammed Bahatti̇n Tanyolaç

Turkish Journal of Agriculture and Forestry

Lentil, which belongs to the family Leguminosae (Fabaceae), is a diploid (2n = 2x = 14 chromosomes) self-pollinating crop with a genome size of 4063 Mbp. Because of its nutritional importance and role in the fixation of nitrogen from the atmosphere, lentil is a widely used crop species in molecular genetic studies. By using DNA markers, to date, a limited number of polymorphic bands have been generated. Therefore, it is necessary to develop additional markers to saturate the genome at high density. Single nucleotide polymorphism (SNP) markers are promising for this purpose because of their abundance, stability, and heredity; they …
