1. Suppressor of zeste 12, a Polycomb group gene in Drosophila melanogaster; one piece in the epigenetic puzzle
Sammanfattning : In multicellular organisms all cells in one individual have an identical genotype, and yet their bodies consist of many and very different tissues and thus many different cell types. Somehow there must be a difference in how genes are interpreted. So, there must be signals that tell the genes when and where to be active and inactive, respectively. LÄS MER
2. Evolution of a family of plant genes with regulatory functions in development; studies on Picea abies and Lycopodium annotinum
Sammanfattning : This work is focused on the molecular genetic basis for morphological change in evolution. Genes belonging to the MADS-box gene family, which includes members, that determine angiosperm floral organ identity, were isolated and characterised from two non-angiosperm plants; Norway spruce (Picea abies) and the club moss (Lycopodium annotinum).

3. Cell fate specification by Ras-mediated cell signalling in C. elegans
Sammanfattning : Induction of vulval fates in the C. elegans hermaphrodite is mediated by a conserved RTK/Ras/MAP kinase signalling pathway, in which the core components can be placed into a linear genetic and biochemical pathway. However, the events that occur downstream of this pathway are not yet well understood. LÄS MER
4. Single-cell RNA sequencing as a tool to study panarthropod evolution
Sammanfattning : Panarthropoda is a monophyletic group comprised of arthropods and lobopods, molting animals with a segmented body, paired appendages, dorsal brain, and ventral nerve cords. Evolutionary Developmental Biology (EvoDevo) is an interdisciplinary field that seeks to understand how changes in development form the basis for variations in morphology and phenotypic evolution, including the genetic network underlying these processes.

5. Genetic Mechanisms Regulating the Spatiotemporal Modulation of Proliferation Rate and Mode in Neural Progenitors and Daughter Cells during Embryonic CNS Development
Sammanfattning : The central nervous system (CNS) is a hallmark feature of animals with a bilateral symmetry: bilateria and can be sub-divided into the brain and nerve cord. One of the prominent properties of the CNS across bilateria is the discernible expansion of its anterior part (brain) compared with the posterior one (nerve cord). LÄS MER
