- Two Norway spruce (Picea abies (L.) Karst.) genes belonging to class I of the KNOTTED1-like homeobox (KNOX) genes, HBK2 and HBK3, were cloned with PCR-based methods. The expression of these and a previously characterised related gene, HBK1, in different organs and during somatic embryogenesis was studied with RTPCR. Transcripts of all three genes were detected in stems, roots and in cone buds, but not in needles. HBK1 and HBK3 are expressed throughout development in a normal cell line with embryogenic potential and in a cell line unable to form somatic embryos. HBK2 is expressed in the normal cell line, but not in the developmentally arrested cell line. This suggests that the HBK2 gene is involved in the somatic embryo development.

- Abstract in UndeterminedThe medical technology (medtech) industry in Sweden is situated withina complex innovation ecosystem, in which various stakeholders from the public,private and academic sectors need to collaborate to meet demands on effective andeffi cient healthcare. Demographics are changing and those in need of healthcare arenot only larger in numbers than ever but they are also more knowledgeable anddemanding. Increasing innovative performance is crucial in both the private andpublic healthcare sectors, but bold steps forward need to be taken in light of stricterrules and regulations for how healthcare stakeholders should manage both theirinternal processes and the ways in which they interact with other stakeholders in thelarger innovation system. The traditional way in which medtech companies gainaccess to user needs, primarily working through a sales–purchasing relationshipwith the public healthcare sector, is outdated and needs to be replaced with anincreasingly collaborative and cocreative model of healthcare innovation.This chapter describes experiences and lessons learned from InnoPlant, a 3-year(2008–2011) action learning project involving three companies from the Swedishmedtech industry, two county/regional councils responsible for public healthcare,and four academic institutions—carried out within the framework of the SwedishProduct Innovation Engineering program (PIEp). The purpose of the project was toadvance the capability of stakeholders from the public, private, and academic sectorsto collaborate in the cocreation of healthcare innovations.

Framträdanden : Performativitetsteoretiska tolkningar av Tadeusz Kantors konstnärskap
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The subject of this dissertation is the art of the Polish theatre director, set designer, and visual artist Tadeusz Kantor (1915–1990) and its inherent width of artistic expressions. The aim is to contribute with new interpretations that add to previous research that primarily has studied the body of work from the perspectives of the artist’s intention and biography, and divided his artistic work between visual art and theatre. By using perspectives from theories of performativity, the starting-point for the study is that artworks interplay with a presumed spectator, contribute to the interpretation, and continue to produce new meaning beyond the original context. The study sets out to answer how the interaction between artwork and spectator can be understood, and what effects the artworks have on each other, when being analysed together, mediated by public presentations. Two exhibitions, one anthology, and a group of artworks from the respective presentations, are being analysed. The first analysis explores the solo exhibition Tadeusz Kantor, emballage at Kulturhuset, Stockholm, 1975–76. Questions regarding representation, materiality, and conceptual modes are discussed in relation to a presumed spectator. In the following analysis, the anthology Tadeusz Kantor: Ein Reisender – seine Texte und Manifeste, published by Verlag für moderne Kunst & Institut für moderne Kunst, 1988, is analysed. In this chapter issues related to verbal and visual expressions are being discussed in relation to the motif of the book, that is identified as the literary narrator. In the last analysis, the retrospective exhibition Tadeusz Kantor at Migros Museum für Gegenwartskunst, Zürich, 2008, is explored. The chapter deals with issues related to spatial, material, and temporal aspects, connecting to a theoretical discussion on the live event of performance and theatre and their subsequent reproductions. The dissertation demonstrates how questions of media and materiality can deepen the way we understand the oeuvre of an artist that actively shaped the reception of his work with contextual references and themes. The chosen perspective and method take the artworks in a relatively unexplored direction, showing how public appearances can be considered as events of becoming.

Meristem Maintenance in Arabidopsis thaliana
- 2004
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The shoot apical meristem (SAM) is the structure that shapes the aerial architecture of the plant, by producing lateral organs throughout development. In the model plant Arabidopsis thaliana, the SAM is always identifiable as a characteristic dome, whether it is found in the centre of a rosette of leaves or at the tip of an inflorescence. When senescence occurs and organogenesis ceases, the now inactive SAM still retains its characteristic appearance and it is never consumed into a terminal structure, such as a flower. Mutant plants that undergo termination represent a valuable tool to understand how the SAM structure and function are maintained during plant life. The aim of this work was to investigate the dynamics of meristem development through morphological and genetic studies of three Arabidopsis mutants that exhibit distinct modes of SAM termination: distorted architecture 1 (dar1), adenosine kinase 1 (adk1) and terminal flower 2 (tfl2). The dar1 mutation is characterised by a severely distorted cellular architecture within the SAM. We propose that dar1 affects the pattern of cell differentiation and/or cell proliferation within the SAM apical dome, resulting in termination by meristem consumption. Instead, the adk1 mutation affects the organogenic potential of the SAM, without altering its structure. The adk1 mutant has increased levels of cytokinins and, as a consequence of this, cell division is enhanced and cell differentiation is prevented in the apex, causing termination by meristem arrest. Finally, tfl2 is mutated in the conserved chromatin remodelling factor HP1, a transcriptional repressor with multiple roles during plant development. The tfl2 SAM terminates by conversion into a floral structure, due to de-repression of floral identity genes. Interestingly, tfl2 mutants also show an altered response to light, an indication that TFL2 might act as a repressor also in the context of light signalling.
