  2. 1. The significance of ethylene and ETHYLENE RESPONSE FACTORS in wood formation of hybrid aspen

    Author : Bernard Wessels; Hannele Tuominen; Judith Felten; Totte Niittylä; Kurt Fagerstedt; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ethylene; wood formation; hybrid aspen; Populus; ETHYLENE RESPONSE FACTOR; ERF85; ERF139; cambium; lignin; xylem expansion; secondary cell wall; tension wood; cambial derivative cell fate; vessel element; time-lapse photography; molekylär bioteknik inst f nat vet biokemi ; molecular biotechnology dept of biochem ; genetik; Genetics; Physiological Botany; fysiologisk botanik;

    Abstract : The woody tissues serve to stabilise plants, store nutrients and translocate water and minerals. The formation of wood, or ’secondary xylem’, follows a well-defined developmental gradient which is initiated by cell division activity in the vascular cambium. READ MORE

    Author : Jenny Lundqvist; Cathrine Persson; Antonio Barragan; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Malaria; Plasmodium; relapsing fever; Borrelia; persistent; concomitant infections; polyamines; Molecular biology; Molekylärbiologi; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar; molekylär bioteknik inst f molekylärbiologi ; molecular biotechnology dept of molecular biology ; Infectious Diseases; infektionssjukdomar;

    Abstract : Infectious diseases such as malaria and relapsing fever borreliosis (RF), cause severe human mortality and morbidity in developing countries. Malaria, caused by Plasmodium spp. parasites, is estimated by the World Health Organization to cause 1.5-2. READ MORE

  5. 3. Towards forecasting epigenetic repression

    Author : Moa J. Lundkvist; Yuri B. Schwartz; Ludvig Lizana; Peter V. Kharchenko; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; epigenetics; Polycomb; PRC1; PRC2; H3K27 methylation; Monte-Carlo simulation; chromatin structure; Drosophila; molekylär bioteknik inst f molekylärbiologi ; molecular biotechnology dept of molecular biology ;

    Abstract : Multicellular organisms form many different cell types from one genome, which requires differential gene activity. The Polycomb system upholds the correct gene expression programs by epigenetically silencing genes that encode critical transcription regulators. READ MORE

  6. 4. Studies on secreted cysteine proteases of Streptococcus pyogenes : IdeS and SpeB

    Author : Reine Vindebro; Ulrich von Pawel-Rammingen; Wolfgang Knecht; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Streptococcus pyogenes; Group A Streptococci; GAS; virulence factor; IdeS; SpeB; cysteine protease; protease inhibitor; IgG; immune evasion; molekylär bioteknik inst f molekylärbiologi ; molecular biotechnology dept of molecular biology ;

    Abstract : The pathogen Streptococcus pyogenes is a significant cause of human morbidity and mortality. Most of the work in this thesis is focused on streptococcal virulence factor IdeS, but the thesis also features work on SpeB, another streptococcal virulence factor. READ MORE

  7. 5. Novel resources enabling comparative regulomics in forest tree species

    Author : David Sundell; Torgeir Hvidsten; Klaas Vandepoele; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Comparative genomics; Web resource; Wood development; RNA-Seq; Forestry; Lignocellulose; Regulomics; High-spatial resolution; Populus tremula; Picea abies; Orthology.; biology; biologi; molekylär bioteknik inst f nat vet biokemi ; molecular biotechnology dept of biochem ;

    Abstract : Lignocellulosic plants are the most abundant source of terrestrial biomass and are one of the potential sources of renewable energy that can replace the use of fossil fuels. For a country such as Sweden, where the forest industry accounts for 10% of the total export, there would be large economical benefits associated with increased biomass yield. READ MORE
