Here we report on the molecular identification, guard cell expression and functional
characterization of AtGORK, an Arabidopsis thaliana goutward rectifying K + channel. GORK …

… Petra Spoormaker for help and support during the early stage of the project. We also thank
Michaela Lehnen, Petra … We are grateful to Petra Spoormaker for help and support during the …

The putative two‐pore Ca 2+ channel TPC1 has been suggested to be involved in
responses to abiotic and biotic stresses. We show that AtTPC1 co‐localizes with the K + ‐selective …

Auxin is a key regulator of plant growth and development, but the causal relationship
between hormone transport and root responses remains unresolved. Here we describe auxin …

The Arabidopsis genome encodes for 20 members of putative ligand-gated channels, termed
glutamate receptors (GLR). Despite the fact that initial studies suggested a role for GLRs in …

In search for the cellular and molecular basis for differences in aluminum (Al) resistance
between maize (Zea mays) cultivars we applied the patch-clamp technique to protoplasts …

The phytohormone abscisic acid (ABA) reports on the water status of the plant and induces
stomatal closure. Guard cell anion channels play a central role in this response, because …

Stomatal opening represents a major determinant of plant productivity and stress management.
Because plants lose water essentially through open stomata, volume control of the pore‐…

Light is a central regulator of plant growth and development. Among the processes triggered
by blue and UV-A light, phototropism, stomatal movement, and chloroplast orientation rely …

Malate is a characteristic metabolite in the photosynthesis of C4 and CAM plants. Furthermore,
changes in the intracellular concentration of this organic acid provide part of the osmotic …
