High resolution genetic and physical mapping of a major powdery mildew resistance locus in barley
(2018-10-01)Barley powdery mildew caused by Blumeria graminis f. sp. hordei (Bgh) is a foliar disease with potentially severe impact on yield and malt quality. The cultivated barley lines and landraces have proven to be valuable sources ... -
Host-parasite interaction between the potato tuber rot nematode (Ditylenchus destructor), stem nematode (Ditylenchus dipsaci) and potato
(2015-03-18)Nematodes are among important pest constraints influencing potato production worldwide. The tuber rot nematode, Ditylenchus destructor Thorne 1945, and the stem nematode, Ditylenchus dipsaci (Kühn, 1857) Filipjev, 1936, ... -
Household Energy Consumption and Dependency on Common Pool Forest Resources: The Case of Kakamega Forest, Western Kenya.
(2013-03-19)Biomass is still the dominant source of energy used by most rural households in the developing world. Current use patterns have been linked to adverse effects on forest resources. Alternative fuels such as kerosene could ... -
Household savings in rural Pakistan
(2002-03-15)The present study analyses some conceptual and empirical issues of the saving behavior of the rural population in Pakistan. The major emphasis of the study is to answer the following ... -
How entomopathogenic endophytic fungi modulate plant-insect interactions
(2017-06-07)Tomato plants host multiple microbes able to colonize plant tissues endophytically without causing symptoms of infections. Whether these microorganisms living inside the plants co-exist completely undetected by the plant ... -
Hummeln in der Agrarlandschaft
(2004-06-16)Bumblebees (Bombus spp. (Latreille), Hymenoptera: Apidae) pollinate a wide range of wild plants and crops in agroecosystems. This important ecosystem service might be endangered by the ... -
Identification of candidate signature genes and key regulators associated with trypanotolerance in the Sheko breed
(2020-05-19)African Animal Trypanosomiasis (AAT) is caused by a protozoan parasite that affects the health of livestock. Livestock production in Ethiopia is severely hampered by AAT and various controlling measures were not successful ... -
Identification of Export Opportunities for Syrian Citrus Growers to the EU: A Supply Chain Perspective
(2013-07-19)Syrian agriculture faces new opportunities in a liberalized trading world. The European Union has been one of the most important new markets for the Syrian citrus output but trading among the neighbors has to expand in ... -
Identification of genes induced in the vascular pathogen Verticillium longisporum by xylem sap metabolites of Brasscia napus using an improved genome-wide quantitative cDNA-AFLP
(2009-11-25)Functional transcriptomics is vital in biology. Comparative analysis of the transcriptome in different physiological or developmental stages facilitates the assignment of biological functions ... -
Identification of molecular genetic causes of bull infertility
(2021-11-18)This is a cumulative thesis that includes three different topics around male infertility in cattle and canine diseases. Whole genome association analysis (GWAS) and whole genome sequencing (WGS), as well as additional ... -
Identification of molecular role of Pelota protein in proliferation and differentiation of male germ stem cells by analysis of conditional knock-out mice
(2015-05-27)Pelota (Pelo) is an evolutionally conserved gene, which has been characterized in various species. In Drosophila, Pelo deficiency affects both male and female fertility. The molecular function of PELO has been extensively ... -
Identification of molecular-genetic causes for osteogenesis imperfecta, interdigital hyperplasia and ribosomopathies in cattle
(2020-02-06)Musculoskeletal anomalies are a heterogeneous group of fairly common, often with severe clinical symptoms, but mostly fatal disorders in human and animals. By far, complex vertebral malformation (CVM) and Brachyspina are ... -
Identification of regulatory SNPs and epistatic SNP pairs using deep learning and information theory
(2022-08-24)In the last two decades, new technologies have made DNA genotyping and sequencing far more time and cost efficient. The resulting tremendous increase in the amount of available genomic data allows for a deeper understanding ... -
Identification of resistance parameters / mechanisms of sugar beet (Beta vulgaris) to green peach aphid Myzus persicae and black bean aphid Aphis fabae
(2025-03-07)The infestation of two aphid species, the green peach aphid (Myzus persicae) and black bean aphid (Aphis fabae), along with the viruses they transmit, causes significant yield losses in sugar beet (Beta vulgaris). With ... -
Identification of resistance sources and characterization of resistance factors in Brassica species to Verticillium longisporum
(2008-03-18)The increasing area of oilseed rape cultivation particularly in the northern European countries has significantly promoted Verticillium longisporum, the causal agent of "Verticillium wilt" of Brassica crops, and thus ... -
