  1. 16. On diverse biophysical aspects of genetics : from the action of regulators to the characterization of transcripts

    Författare :Aymeric Fouquier D´Hérouel; Erik Aurell; Felix Ritort; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transcription regulation; regulatory motifs; binding affinity; genetic interactions; secondary structure; sequence repeats; transcript characterization; Biological physics; Biologisk fysik;

    Sammanfattning : Genetics is among the most rewarding fields of biology for the theoretically inclined, offering both room and need for modeling approaches in the light of an abundance of experimental data of different kinds. Many aspects of the field are today understood in terms of physical and chemical models, joined by information theoretical descriptions. LÄS MER

  3. 17. Genetics of Tetrapyrrole Synthesis in Gram-Positive Bacteria

    Författare :Per Johansson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; siroheme; tetrapyrrole synthesis; Bacillus subtilis; Bacillaceae; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : The organization and regulation of genes for tetrapyrrole synthesis were studied in low G+C Gram-positive bacteria. Clusters of genes encoding enzymes for tetrapyrrole biosynthesis were cloned from Bacillus sphaericus, Bacillus stearothermophilus, Brevibacillus brevis and Paenibacillus macerans. LÄS MER

  4. 18. Mastitis in dairy cows in Rwanda : prevalence, aetiology, antimicrobial resistance, molecular epidemiology and effects on milk quality

    Författare :Jean-Baptiste Ndahetuye; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The milk sector in Rwanda can be made competitive through improved udder health resulting in higher milk yields. This thesis investigated prevalence and aetiology of subclinical mastitis (SCM) in dairy cows, antimicrobial resistance and molecular epidemiology of udder pathogens. LÄS MER

  5. 19. The genetics of antibiotic production and the role of antibiotics in biological control of Erwinia amylovora by Erwinia herbicola

    Författare :Sandra A. I. Wright; Cornell University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biological sciences; fire blight; pantocin; Plant pathology; Microbiology; Molecular biology; 0480:Plant pathology; 0307:Molecular biology; 0410:Microbiology;

    Sammanfattning : Erwinia herbicola is an epiphyte of apple and pear with potential as a biocontrol agent of Erwinia amylovora, which causes fire blight. This research aimed to assess the relative role of antibiotics produced by E. herbicola, Eh318 as a mechanistic basis for biocontrol. LÄS MER

  7. 20. Comparative bioinformatics analyses of transcriptome and epigenome data using bovine model systems

    Författare :Naveed Jhamat; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Bioinformatics methodology is used to understand complex biological processes in molecular biology, genetics and epigenetics. This thesis performed analysis of the complex biological processes controlling reproduction in mammals including dairy cattle. LÄS MER
