Link toward the SiCE lab web page

The main focus of the Cell Signaling group is to unravel the mechanisms behind cell-cell communication in plants.

Plant growth and development are regulated by interactions between the environment and endogenous developmental programs. The “Cell Signaling” lab is interested in identifying the molecular and cellular mechanisms behind signal transduction and cell-cell communication in plants. We use Arabidopsis thaliana, an ideal organism for integrative biology, genetics and molecular investigations of signaling networks.

The “Cell Signaling” lab is composed of two groups that study cell signaling with an emphasis on receptor kinases and intracellular trafficking:

 Pollen-pistil interaction
 Lipid signaling in plant cell division and organogenesis
 Lipid signaling in development and environmental interactions


Pollen-pistil interaction

Leader : Isabelle Fobis-Loisy - Thierry Gaude

Self-incompatibility (SI) is a cell/cell recognition system that prevents inbreeding in flowering plants by allowing the female organ, the pistil, to discriminate between self- and non self-pollen grains. In the Brassicaceae family, SI response is controlled by a receptor-ligand interaction, which involves the SRK receptor (S-locus Receptor Kinase) expressed in the epidermal cells of the pistil (stigmatic papillae) and its ligand SCR (S-locus Cysteine-Rich) carried by the pollen grain (Gaude et al., 2006).

Although the plant receptor-like kinase (RLK) family consists of more than 400 putative transmembrane proteins in Arabidopsis thaliana, less than half a dozen have clearly identified ligands with known physiological functions. Interestingly, SI signaling presents some unique features compared with the other known plant signaling pathways. Indeed, we unexpectedly found that SRK accumulates in intracellular compartments, with only a small portion being detected in patches at the plasma membrane (Ivanov and Gaude, 2009). Although not very abundant at the cell surface, we nevertheless demonstrated that SRK activation upon ligand binding takes place at the plasma membrane and is followed by internalization of the SRK-ligand complex and its transport to sorting endosomes (Ivanov and Gaude, 2009).

We now want to address :
 What is the role of endocytosis and SRK trafficking in SI response?
 How papilla cells discriminate between self- and non-self pollen grains at the same time?
 What are the mechanisms that control papilla cell morphogenesis and polarity?

Lipid signaling in plant cell division and organogenesis

Leader : Marie-Cecile Caillaud

How plant cells positioned their division planes during morphogenesis ?

JPEGDuring the life cycle of any multicellular organism, cell division contributes to the generation of specialized cells, which are necessary to form tissues and carry out particular functions. Therefore, the mechanisms of cell division need to be tightly regulated, as malfunctions in their control can lead to tumour formation or developmental defects. This is particularly true in land plants, where cells cannot migrate and therefore cytokinesis is key for morphogenesis. In plant, cell division is executed in radically different manners than animals, with the appearance of new structures (cell plate, cytokinetic phragmoplast and the preprophase band (PPB) of microtubules) and the disappearance of ancestral mechanisms (cleavage, centrosomes).

A crucial feature of cell division is how cells position their division plane. It has even more significance for walled organisms, because their cells are embedded and cannot relocate. The memory of the cell division plane is maintained throughout plant cell division by a landmark at the equatorial periphery of the cell. Recent evidence shows that membrane lipids such as phosphoinositides (PIPs) are important for cell division orientation in plants. Phosphoinositides are ubiquitous regulators of signal transduction events in eukaryotic cells. They are produced by mono-, bis- and trisphosphorylation of the inositol head group of phosphatidylinositol. Due to their charged nature, phosphoinositides may create localized docking sites for proteins—for example, cytoskeletal and trafficking regulators—thereby defining specific membrane domains.

We are currently investigating the interplay between the phosphoinositides and the cytoskeleton during plant cell division using Arabidopsis and BY2-cells as models.

We want now to address:
 How the PIP-patterning is organized at the plasma membrane of dividing cells?
 What is the impact of local perturbation of the PIPs-patterning during cell division?
 What are the upstream components responsible for the distribution of the PIPs during division?

Results gained from the ongoing research will provide a better understanding of the signaling mechanisms coupling PIP-metabolism and cell division, the latest being fundamental in regulating organismal growth.

Lipid signaling in development and environmental interactions

Leader : Yvon Jaillais

How individual cells communicate with each other and with the environment to shape plant architecture?

Plants are sessile organisms and therefore must constantly adapt their growth and architecture to an ever-changing environment. It is the delicate balance between developmental and environmental signals that shapes the architecture of the plants. Individual cells constantly integrate those cues into cellular output, that gives rise to new organs. Cells are equipped with receptor molecules that allow communication with other cells in the organism and detection of changes in their surrounding environment, such as changes in light quality, nutrient availability, attack by pathogens...

The plasma membrane plays a critical role in regulating exchanges between the intra- and extracellular milieu and in controlling cell-to-cell communication. The aim of our group is to understand what makes the plasma membrane unique with regard to other membrane compartments and as such competent for signaling. We want to understand how signaling domains are being defined at the plant plasma membrane, both at the level of the cell (e.g., polar domains) but also at the micrometer scale (e.g., membrane microdomains). We also plan to address how these signaling domains evolve during the course of signaling and what are their functional roles during cell-cell communication.

Anionic phospholipids (e.g. phosphoinositides, PIPs) are minor lipids in membranes but they have a huge impact on cell signaling and organelle identity. They not only recruit proteins to specific cellular compartments, but they also deeply impact membrane biophysics properties. Furthermore, their production is tightly and dynamically regulated during development and interaction with the environment.

We now want to address :
 What are the anionic lipids involved in plasma membrane organization and how?
 What are the functions of anionic lipids and their interacting proteins in hormone signaling? (e.g. brassinosteroid and auxin signaling)
 How are anionic lipids orchestrating membrane trafficking and cell polarity?
 How is anionic lipids homeostasis regulated by changes in the environment and contribute to plant adaptation?
