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-…

Members of the plant NITRATE TRANSPORTER 1/PEPTIDE TRANSPORTER (NRT1/PTR)
family display protein sequence homology with the SLC15/PepT/PTR/POT family of peptide …

In plants, transport processes are important for the reallocation of defence compounds to
protect tissues of high value 1 , as demonstrated in the plant model Arabidopsis, in which the …

S-type anion channels are direct targets of abscisic acid (ABA) signaling and contribute to
chloride and nitrate release from guard cells, which in turn initiates stomatal closure. SLAC1 …

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 …

Members of the AKT2/3 family have been identified as photosynthate-induced phloem K +
channels. Here we describe the isolation and characterisation of an AKT2/3 loss-of-function …

In contrast to animals and lower plant species, sperm cells of flowering plants are non-motile
and are transported to the female gametes via the pollen tube, ie the male gametophyte. …

The phloem network is as essential for plants as the vascular system is for humans. This
network, assembled by nucleus- and vacuole-free interconnected living cells, represents a long …

Under drought stress, the stress hormone ABA addresses the S n R kinase OST 1 via its
cytosolic receptor and the protein phosphatase ABI 1. Upon activation, OST 1 phosphorylates …

The phytohormone abscisic acid (ABA) plays a key role in the plant response to drought
stress. Hence, ABA-dependent gene transcription and ion transport is regulated by a variety of …
