Activity of guard cell anion channel SLAC1 is controlled by drought-stress signaling kinase-phosphatase pair
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. TwoExpand

Guard cell anion channel SLAC1 is regulated by CDPK protein kinases with distinct Ca2+ affinities
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 asExpand

Arabidopsis V-ATPase activity at the tonoplast is required for efficient nutrient storage but not for sodium accumulation
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 tonoplastExpand

Perception of the Arabidopsis Danger Signal Peptide 1 Involves the Pattern Recognition Receptor AtPEPR1 and Its Close Homologue AtPEPR2*
Plasma membrane-borne pattern recognition receptors, which recognize microbe-associated molecular patterns and endogenous damage-associated molecular patterns, provide the first line of defense inExpand

Recalibrating Equus evolution using the genome sequence of an early Middle Pleistocene horse
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 toExpand

AtALMT12 represents an R-type anion channel required for stomatal movement in Arabidopsis guard cells.
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 fromExpand

The Stomatal Response to Reduced Relative Humidity Requires Guard Cell-Autonomous ABA Synthesis
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 thatExpand

Open stomata 1 (OST1) kinase controls R-type anion channel QUAC1 in Arabidopsis guard cells.
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-typeExpand

True single-molecule DNA sequencing of a pleistocene horse bone.
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 dependentExpand
