  • Plant Transgenesis
    entirely new field such as epigenetics Peter Meyer The first part starts with a personal impression of Patricia Zambryski and a dialogue with Marc De Block who both recalled the early stages and first successes in plant transgenic research of the Ghent research group headed by Marc Van Montagu and the late Jeff Schell Of course an interview with Marc Van Montagu could not be omitted because he is one of the founding persons of plant biotechnology This Special Issue is divided in four parts The first section including the personal reminiscence and dialogues mentioned above consists of an introduction to the principles of higher plant transformation from the agrobacterial and plant sides Vitaly Citovsky Mieke Van Lijsebettens and Kan Wang The second part highlights the importance of transgenic research in basic plant biology Indeed the functional analysis of genes was boosted by genetic transformation and construction of knockout and overexpression lines not only in model plants such as Arabidopsis thaliana Minami Matsui but also in crops such as Leguminosae Pascal Ratet Three reviews Darren Wells Miriam Gifford and Dave Jackson illustrate the prospects of the use of reporter genes in the cell biological analysis of gene functions in the biochemistry of protein protein interactions and in the monitoring of hormonal fluxes Although the focus of this publication is mainly on higher plants one paper was included that reviews the potential of Physcomitrella patens in evolutionary and basic biology research Wolfgang Frank The third part concentrates on biotechnological applications such as metabolic pathway engineering Paul Christou antibody production in seeds for passive immunization Ann Depicker biotechnological aspects of nutrient uptake Luis Herrera Estrella and emerging transgenic research in Liliaceae Richard Immink The fourth section consists of a compilation of promising novel technologies to position precisely the transgene of interest within

  • Introduction
    organisms PCD has adopted a multitude of functions in physiological and pathological development In both animals and plants defects in the molecular control of PCD can cause severe developmental aberrations and diseases The significance of PCD for human health has been recognized decades ago and today we have a detailed understanding of the molecular regulation of apoptosis and some other forms of animal PCD In plants however we still know comparatively little about PCD despite the fact that different forms of PCD occur throughout plant life and many of them are critical for plant health and fitness as well as for successful growth and reproduction Our lab is interested in the molecular control of plant PCD during vegetative and reproductive development Dozens of different cell types tissues and organs execute a tightly regulated actively controlled cell death in the course of their differentiation and development We identified several commonly expressed plant cell death markers suggesting that a conserved PCD core machinery controls initiation and execution of cell death in diverse developmental contexts Using cutting edge molecular cell and systems biology approaches we are unravelling the mechanisms that control preparation initiation and execution of plant PCD as an inherent part of cellular differentiation Most research is performed in the framework of vegetative and reproductive development of the model plant Arabidopsis thaliana but additionally we investigate PCD during fertilization and seed set of maize Zea mays as an important seed producing crop plant Projects Moritz Nowack Group Members Lab Members and Alumni Group in Action Publications Moritz Nowack Research Groups Alain Goossens Lab Ann Depicker Lab Bruno Cammue Lab Daniel Van Damme Lab Dirk Inzé Lab Frank Van Breusegem Lab Geert De Jaeger Lab Ive De Smet Lab Jenny Russinova Lab Lieven De Veylder Lab Mieke Van Lijsebettens Lab Moritz Nowack Lab
