Activity of guard cell anion channel SLAC1 is controlled by drought-stress signaling kinase-phosphatase pair
- D. Geiger, S. Scherzer, +9 authors R. Hedrich
- Biology, Medicine
- Proceedings of the National Academy of Sciences
- 15 December 2009
In response to drought stress the phytohormone ABA (abscisic acid) induces stomatal closure and, therein, activates guard cell anion channels in a calcium-dependent as well as-independent manner. Two… Expand
Guard cell anion channel SLAC1 is regulated by CDPK protein kinases with distinct Ca2+ affinities
- D. Geiger, S. Scherzer, +9 authors R. Hedrich
- Medicine, Biology
- Proceedings of the National Academy of Sciences
- 12 April 2010
In response to drought stress, the phytohormone abscisic acid (ABA) induces stomatal closure. Thereby the stress hormone activates guard cell anion channels in a calcium-dependent, as well as… Expand
Arabidopsis V-ATPase activity at the tonoplast is required for efficient nutrient storage but not for sodium accumulation
- Melanie Krebs, D. Beyhl, +5 authors K. Schumacher
- Biology, Medicine
- Proceedings of the National Academy of Sciences
- 26 January 2010
The productivity of higher plants as a major source of food and energy is linked to their ability to buffer changes in the concentrations of essential and toxic ions. Transport across the tonoplast… Expand
Perception of the Arabidopsis Danger Signal Peptide 1 Involves the Pattern Recognition Receptor AtPEPR1 and Its Close Homologue AtPEPR2*
- E. Król, T. Mentzel, +9 authors R. Hedrich
- Biology, Medicine
- The Journal of Biological Chemistry
- 3 March 2010
Plasma membrane-borne pattern recognition receptors, which recognize microbe-associated molecular patterns and endogenous damage-associated molecular patterns, provide the first line of defense in… Expand
Recalibrating Equus evolution using the genome sequence of an early Middle Pleistocene horse
- L. Orlando, Aurélien Ginolhac, +53 authors E. Willerslev
- Biology, Medicine
- Nature
- 4 July 2013
The rich fossil record of equids has made them a model for evolutionary processes. Here we present a 1.12-times coverage draft genome from a horse bone recovered from permafrost dated to… Expand
AtALMT12 represents an R-type anion channel required for stomatal movement in Arabidopsis guard cells.
- S. Meyer, P. Mumm, +7 authors R. Hedrich
- Biology, Medicine
- The Plant journal : for cell and molecular…
- 1 September 2010
Stomatal pores formed by a pair of guard cells in the leaf epidermis control gas exchange and transpirational water loss. Stomatal closure is mediated by the release of potassium and anions from… Expand
The Stomatal Response to Reduced Relative Humidity Requires Guard Cell-Autonomous ABA Synthesis
- Hubert Bauer, P. Ache, +11 authors R. Hedrich
- Biology, Medicine
- Current Biology
- 7 January 2013
Stomata are pores on the leaf surface, bounded by two guard cells, which control the uptake of CO(2) for photosynthesis and the concomitant loss of water vapor. In 1898, Francis Darwin showed that… Expand
Multiple calcium-dependent kinases modulate ABA-activated guard cell anion channels.
- S. Scherzer, T. Maierhofer, K. Al-Rasheid, D. Geiger, R. Hedrich
- Biology, Medicine
- Molecular plant

Open stomata 1 (OST1) kinase controls R-type anion channel QUAC1 in Arabidopsis guard cells.
- Dennis Imes, P. Mumm, +4 authors R. Hedrich
- Biology, Medicine
- The Plant journal : for cell and molecular…
- 1 May 2013
Under drought stress, the stress hormone ABA addresses the SnR kinase OST1 via its cytosolic receptor and the protein phosphatase ABI1. Upon activation, OST1 phosphorylates the guard cell S-type… Expand
True single-molecule DNA sequencing of a pleistocene horse bone.

- Medicine, Biology
- Genome research
- 1 October 2011
Second-generation sequencing platforms have revolutionized the field of ancient DNA, opening access to complete genomes of past individuals and extinct species. However, these platforms are dependent… Expand
