11. Comparative Genomics of Endosymbiotic Bacteria
Sammanfattning : Genomes of intracellular bacteria are thought to be the products of reductive evolution. They have evolved from ancestral genomes of free-living bacteria through a process of massive gene loss. LÄS MER
12. Developmental phase transitions in Norway spruce : a molecular approach to identify regulatory mechanisms
Sammanfattning : Plant development proceeds through distinct phases that are controlled by complex networks of regulatory genetic circuits and fine-tuned by environmental and endogenous cues. Many of these regulatory networks have been unraveled in annual and perennial angiosperms, while they remain predominantly unknown in ecologically and economically important gymnosperm species such as the conifers.

13. Developmental Perspectives on Transfer in Third Language Acquisition
Sammanfattning : The aim of this thesis is to examine how learner-general developmental stages in syntax and morphology interact with a language-specific factor, the influence of—or transfer from— the language learner’s first (L1) or previously learned second (L2) language on the acquisition of a third language (L3). It thereby aims to bring together two lines of research whose main concepts—transfer and developmental stages—have often been defined as mutually exclusive and generally studied in separate lines of research.

14. Controlled auxin biosynthesis and transport are important for developmental decisions in the early diverging land plant Physcomitrella patens
Sammanfattning : The aim of this thesis was to increase our understanding of the importance of the plant hormone auxin in land plant evolution. The role of a number of auxin regulatory network components in developmental decisions during the haploid phase of the life cycle of the model moss Physcomitrella patens, which belongs to the early diverging bryophyte group of land plants, was investigated.

15. Changes in global gene expression and auxin dynamics during embryo development in conifers
Sammanfattning : Conifers are of great economical importance, but our knowledge about how the development of conifers is regulated is limited. The over-all aim of this study has been to gain a better understanding of the molecular regulation of embryo development in conifers. LÄS MER
