Regulation of guard cell photosynthetic electron transport by nitric oxide.
Nitric oxide (NO) is one of the key elements in the complex signalling pathway leading to stomatal closure by inducing reversible protein phosphorylation and Ca(2+) release from intracellular stores. As photosynthesis in guard cells also contributes to stomatal function, the aim of this study was to explore the potential role of NO as a photosynthetic regulator. This work provides the first des...
متن کاملAntagonistic regulation of the meristemoid-to-guard mother-cell-transition
The building of a multicellular organism from a single cell is the result of coordinated acquisition of different cell identities in an ordered spatial arrangement. But, how do cells learn about their identity? Stomatal development in Arabidopsis provides perhaps one of the most tractable contexts in which to examine concepts of cell fate determination, as a variety of lineage tracing technique...
متن کاملImproved Performance of Soil Microbial Fuel Cell by Adding Earthworms
Soil microbial fuel cells (SMFCs) are expected as an application to produce sustainable energy. Here, we focused on soil ecosystems, specifically the earthworms which are known to improve soil-fertility by degrading fallen leaves or plant litter. The aim of this study was to investigate the effect of earthworm on power generation of the SMFC. The maximum power density and the internal res...
متن کاملRegulation of abscisic acid-induced stomatal closure and anion channels by guard cell AAPK kinase.
Abscisic acid (ABA) stimulates stomatal closure and thus supports water conservation by plants during drought. Mass spectrometry-generated peptide sequence information was used to clone a Vicia faba complementary DNA, AAPK, encoding a guard cell-specific ABA-activated serine-threonine protein kinase (AAPK). Expression in transformed guard cells of AAPK altered by one amino acid (lysine 43 to al...
متن کاملActivity 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. Two key components of the ABA signaling pathway are the protein kinase OST1 (open stomata 1) and the protein phosphatase ABI1 (ABA insensitive 1). The recently identified guard cell anion channel SLAC1...
