  2. 21. The exosome and the maintenance of genome integrity

    Author : Judit Domingo Prim; Neus Visa; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The RNA exosome acts on different RNA substrates and plays important roles in RNA metabolism. The fact that short non-coding RNAs are involved in the DNA damage response led us to investigate whether the exosome plays a role in DNA repair. READ MORE

  4. 22. Signalling mechanisms and epigenetic regulation of seed development in Arabidopsis thaliana

    Author : Rita Batista; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In flowering plants, seed development starts with a double fertilisation event, leading to the formation of the embryo and the endosperm. Though only the embryo contributes to the next generation, control of endosperm proliferation, as well as the timing of its cellularisation are crucial for embryo viability. READ MORE

  5. 23. Jack of all trades, master of none : the multifaceted nature of H3K36 methylation

    Author : Henrik Lindehell; Jan Larsson; Anders Byström; Peter B. Becker; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; H3K36; histone methylation; dosage compensation; chromosome-specific gene regulation; transposable elements; PIWI piRNA biosynthesis; Set2; Ash1; NSD; Histone 3.3; post-translational modifications; histone modifications; epigenetics; proximity ligation assay; Drosophila; Genetics; genetik; molekylärbiologi; Molecular Biology; Biopharmaceutics; biofarmaci;

    Abstract : Post-translational modifications of histones enable differential transcriptional control of the genome between cell types and developmental stages, and in response to environmental factors. The methylation of Histone 3 Lysine 36 (H3K36) is one the most complex and well-studied histone modifications and is known to be involved in a wide range of molecular processes. READ MORE

  6. 24. BEN-solo proteins in genome architecture and function

    Author : Malin Ueberschär; Qi Dai; Mattias Mannervik; Nicola Iovino; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; gene regulation; transcription; insulators; genome architecture; Polymerase II pausing; chromatin; Drosophila development; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Eukaryotic genomes are organized in a complex manner inside the nucleus of each cell. Chromatin insulators are DNA elements that help to fold the linear DNA fiber in three-dimensional space and partition regulatory gene units. READ MORE

  7. 25. 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
