The HIC signalling pathway links CO2 perception to stomatal development
Stomatal pores on the leaf surface control both the uptake of CO2 for photosynthesis and the loss of water during transpiration. Since the industrial revolution, decreases in stomatal numbers inExpand

The Signaling Peptide EPF2 Controls Asymmetric Cell Divisions during Stomatal Development
Stomata are pores in the plant epidermis that control carbon dioxide uptake and water loss. They are major regulators of global carbon and water cycles [1]. Several signaling components that regulateExpand

Nitric Oxide Sensing in Plants Is Mediated by Proteolytic Control of Group VII ERF Transcription Factors
Summary Nitric oxide (NO) is an important signaling compound in prokaryotes and eukaryotes. In plants, NO regulates critical developmental transitions and stress responses. Here, we identify aExpand

Self-incompatibility in Nicotiana alata involves degradation of pollen rRNA
GAMETOPHYTIC self-incompatibility is a genetically based system of cellular recognition in plants1. It prevents fertilization by pollen bearing an S-allele identical to either of the two S-allelesExpand

Gene‐specific expression and calcium activation of Arabidopsis thaliana phospholipase C isoforms
PI-PLCs synthesise the calcium releasing second messenger IP3. We investigated the expression patterns of the Arabidopsis PI-PLC gene family and measured in vitro activity of encoded enzymes. GeneExpand

Regulatory Mechanism Controlling Stomatal Behavior Conserved across 400 Million Years of Land Plant Evolution
Stomatal pores evolved more than 410 million years ago [1, 2] and allowed vascular plants to regulate transpirational water loss during the uptake of CO(2) for photosynthesis [3]. Here, we show thatExpand

Involvement of sphingosine kinase in plant cell signalling.
In mammalian cells sphingosine-1-phosphate (S1P) is a well-established messenger molecule that participates in a wide range of signalling pathways. The objective of the work reported here was toExpand

Plant immunophilins: functional versatility beyond protein maturation.
Originally identified as the cellular targets of immunosuppressant drugs, the immunophilins encompass two ubiquitous protein families: the FK-506 binding proteins or FKBPs, and theExpand

Phospholipase C is required for the control of stomatal aperture by ABA.
The calcium-releasing second messenger inositol 1,4,5-trisphosphate is involved in the regulation of stomatal aperture by ABA. In other signalling pathways, inositol 1,4,5-trisphosphate is generatedExpand

Land Plants Acquired Active Stomatal Control Early in Their Evolutionary History
Stomata are pores that regulate plant gas exchange [1]. They evolved more than 400 million years ago [2, 3], but the origin of their active physiological responses to endogenous and environmentalExpand
