Extracellular ATP Induces the Accumulation of Superoxide via NADPH Oxidases in Arabidopsis1
Extracellular ATP can serve as a signaling agent in animal cells, and, as suggested by recent reports, may also do so in plant cells. In animal cells it induces the production of reactive oxygenExpand

Evidence of a Novel Cell Signaling Role for Extracellular Adenosine Triphosphates and Diphosphates in Arabidopsis
Extracellular ATP is a known receptor agonist in animals and was previously shown to alter plant growth, and so we investigated whether ATP derivatives could function outside plant cells as signalingExpand

The Role of Annexin 1 in Drought Stress in Arabidopsis1[W]
Annexins act as targets of calcium signals in eukaryotic cells, and recent results suggest that they play an important role in plant stress responses. We found that in Arabidopsis (ArabidopsisExpand

Differential expression of members of the annexin multigene family in Arabidopsis.
Although in most plant species no more than two annexin genes have been reported to date, seven annexin homologs have been identified in Arabidopsis, Annexin Arabidopsis 1-7 (AnnAt1--AnnAt7). ThisExpand

Expression profiling of the Arabidopsis annexin gene family during germination, de-etiolation and abiotic stress.
Annexins are a multigene family in most plant species and are suggested to play a role in a wide variety of essential cellular processes. In Arabidopsis thaliana there are eight different annexinsExpand

Apyrases (Nucleoside Triphosphate-Diphosphohydrolases) Play a Key Role in Growth Control in Arabidopsis1[W][OA]
Expression of two Arabidopsis (Arabidopsis thaliana) apyrase (nucleoside triphosphate-diphosphohydrolase) genes with high similarity, APY1 and APY2, was analyzed during seedling development and underExpand

Extracellular ATP: an unexpected role as a signaler in plants.
ATP and other nucleoside triphosphates not only drive energy-dependent reactions inside cells, but can also function outside the plasma membrane in the extracellular matrix, where they function asExpand

Identification and characterization of annexin gene family in rice
Plant annexins are Ca2+-dependent phospholipid-binding proteins and are encoded by multigene families. They are implicated in the regulation of plant development as well as protection from droughtExpand

Disruption of Apyrases Inhibits Pollen Germination in Arabidopsis1
In Arabidopsis, we previously identified two highly similar apyrases, AtAPY1 and AtAPY2. Here, T-DNA knockout (KO) mutations of each gene were isolated in a reverse genetic approach. The single KOExpand

Apyrase functions in plant phosphate nutrition and mobilizes phosphate from extracellular ATP.
ATP, which is present in the extracellular matrix of multicellular organisms and in the extracellular fluid of unicellular organisms, has been shown to function as a signaling molecule in animals.Expand
