Dynamic networks of protein-protein interactions regulate numerous cellular processes and determine the ability to respond appropriately to environmental stimuli. However, the investigation of protein complex formation in living plant cells by methods such as fluorescence resonance energy transfer has remained experimentally difficult, time consuming and(More)
Plants use sophisticated strategies to balance responses to oxidative stress. Programmed cell death, including the hypersensitive response (HR) associated with successful pathogen recognition, is one cellular response regulated by reactive oxygen in various cellular contexts. The Arabidopsis basic leucine zipper (bZIP) transcription factor AtbZIP10 shuttles(More)
Proline metabolism has been implicated in plant responses to abiotic stresses. The Arabidopsis thaliana proline dehydrogenase (ProDH) is catalysing the first step in proline degradation. Transcriptional activation of ProDH by hypo-osmolarity is mediated by an ACTCAT cis element, a typical binding site of basic leucine zipper (bZIP) transcription factors. In(More)
The post-translational regulation of transcription factors plays an important role in the control of gene expression in eukaryotes. The mechanisms of regulation include not only factor modifications but also regulated protein-protein interaction, protein degradation and intracellular partitioning. In plants, the basic-region leucine zipper (bZIP)(More)
Members of the Arabidopsis group C/S1 basic leucine zipper (bZIP) transcription factor (TF) network are proposed to implement transcriptional reprogramming of plant growth in response to energy deprivation and environmental stresses. The four group C and five group S1 members form specific heterodimers and are, therefore, considered to cooperate(More)
Dynamic networks of protein-protein interactions regulate numerous cellular processes and determine the ability of cells to respond appropriately to environmental stimuli. However, the study of protein complex formation in living plant cells has remained experimentally difficult and time-consuming and requires sophisticated technical equipment. In this(More)
Reversible phosphorylation plays a crucial role in regulating the activity of enzymes and other proteins in all living organisms. Particularly, the phosphorylation of transcription factors can modulate their capability to regulate downstream target genes. In plants, basic domain-containing leucine-zipper (bZIP) transcription factors have an important(More)
We combined single pollen typing with laser-mediated manipulation. After drilling a hole in the wall of a pollen grain from a dioecious plant (Silene latifolia) with a UV-laser microbeam, the single pollen grain was recovered directly in the cap of a PCR tube, using a non-contact method called laser pressure catapulting. The entire genome of the single(More)
