1. Regulatory Control of Autumn Senescence in Populus tremula
Abstract : Autumn senescence is a visually spectacular phenomenon in which trees prepare for the oncoming winter. The mechanism for regulation of autumn senescence in trees has been very hard to pinpoint. In this thesis the main focus is to investigate how autumn senescence is regulated in aspens (Populus tremula). READ MORE

2. A molecular network mediating adventitious root initiation in Arabidopsis thaliana
Abstract : To adapt to the ever-changing rhizosphere conditions, land plants evolved a sophisticated root system. The genetic determinants of the root system establishment have been the targets of natural selection, resulting in a very complex but robust molecular networks and circuits. READ MORE

4. Changes in endogenous cytokinin-like substances in seeds during dormancy release and early germination
Abstract : From studies using non-dormant seeds, Zea mays L. and Phaseotus vulgaris L. transient peaks of endogenous cytokinin-like substances were observed after only 4 h of imbibition. READ MORE

5. Interaction between auxin, cytokinin and ethylene in the regulation of root growth in Pisum sativum L
Abstract : The effects of exogenous auxins (indole-3-acetic acid (IAA), indole-3-butyric acid (IBA) and 2,4-dichlorophenoxyacetic acid (2,4-D)), cytokinins (benzylaminopurine (BAP) and zeatin) and ethylene, applied as the precursor 1 -aminocyclopropane- 1-carboxylic acid (ACC), on the root growth of pea (Pisumsativum L.) seedlings were investigated.
