21. The exosome and the maintenance of genome integrity
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

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

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

24. BEN-solo proteins in genome architecture and function
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

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