1. Molecular regulation of vascular cambium identity and activity
Sammanfattning : In plants, secondary development and wood formation originates from the cell divisions within the vascular meristem, where the vascular stem cells are located. This thesis work presents my results on the molecular regulation of vascular cambium stem cell identity and activity. LÄS MER
2. Monitoring primary carbon metabolism in plants using heavy isotope labelling and mass spectrometry : ¹³CO₂ labelling, detection and estimation in intact plants
Sammanfattning : This thesis covers the possibilities and limitations of studying primary metabolism in intact plants, with special focus on heavy isotope labelling and mass spectrometry methodology. In paper I, a series of Arabidopsis thaliana mutants lacking one or both genes of mitochondrial malate dehydrogenase (mMDH characterised) were characterised. LÄS MER
3. Modification of forest trees by genetic engineering : from design to the field
Sammanfattning : Developing viable genetic engineering methods for cell wall modification in trees is important to improve in a timely manner the properties of lignocellulose for biorefinery applications. New wood cell wall functionalities can be introduced by altered expression of native enzymes or by expressing microbial enzymes in planta. LÄS MER
4. Modelling the development of phyllotactic patterns at the shoot apical meristem of Arabidopsis thaliana
Sammanfattning : The study of phyllotactic patterns have a long history, but the bulk of our detailed understanding of developmental processes in plants comes from research conducted in the last thirty or forty years. New modern techniques have made it possible to study plants in ways that previously was not possible. LÄS MER
5. Neural stem cell-mediated enhanced gene therapy of malignant gliomas using a novel plant thymidine kinase
Sammanfattning : Malignant gliomas are the most common brain tumors in adults. Approximately, 190,000 new patients are diagnosed with malignant gliomas worldwide every year. Unfortunately, the prognosis of malignant gliomas still remains very poor, despite advances in management. LÄS MER
