Optimized root architecture is crucial for efficient water and nutrient uptake, and strongly affects plant growth and seed yield. Our group is interested in the involvement of membrane-associated receptor-like kinases in registering and conveying (positional) information during plant (lateral) root development. Specifically, we are investigating the ACR4-dependent signalling cascade, which we recently showed to be important for root development (De Smet et al. 2008, Science 322:594-597). In the framework of a David Phillips BBSRC Fellowship, we will identify substrates and ligands for the membrane-associated receptor-like kinase ACR4. We will combine the expertise of our lab in genetics and root development with that of partner labs competent in proteome-wide analyses. The characterization of this homeostatic ligand/receptor signalling mechanism, that can integrate mobile signalling molecules to control formative cell divisions during organogenesis, provides an excellent tool to study short range, cell-to-cell communication during growth and development.

Past Research
Very early in my research career (1999-2000), investigating the anatomy of brown algae of the genus Dictyopteris triggered my interest in what controls the development of complex multicellular organisms and distinct cell types. Recently, this interest resulted in two manuscripts on the evolution of auxin signalling - a major control mechanism in land plant development (Lau et al., 2009, Trends Plant Sci 14:182-188; De Smet et al., Plant Phys, 155:209-221).
During my PhD training (2001-2006) at the University of Leeds (U.K.) and at the Ghent University / VIB Department of Plant Systems Biology (Belgium) with H. Zhang and T. Beeckman, respectively, I investigated the role of the phytohormones abscisic acid and auxin during lateral root development (Signora et al., 2001, Plant J 28:655-662; De Smet et al., 2003, Plant J 33:543-555; De Smet et al., 2007, Development 134:681-690; Swarup et al., 2008, Nat Cell Biol 10:946-954). However, my main achievement was to identify ACR4 as the first receptor-like kinase that plays a decisive role in formative cell division in the root (De Smet et al., 2008, Science 322:594-597; De Smet et al., 2009, Nat Cell Biol 11:1166-1173).
After obtaining my PhD degree in 2006, I joined the lab of G. Jürgens at the University of Tübingen and the Max Planck Institute for Developmental Biology (Germany) as a postdoctoral research fellow (2006-2010) funded by EMBO and a Marie Curie Fellowship. During this period I focused on the regulation of gene expression in early embryogenesis (Lau et al., Nat Cell Biol, submitted). But I also investigated to what extent the molecular mechanisms that have been identified in embryo development also play a role in (lateral) root development (De Smet et al., 2010, Proc Natl Acad Sci USA 107:2705-2710; Zhang et al., 2010, Plant J 64:764-774).
After rejoining the Plant Systems Biology Department (VIB) as an FWO-funded postdoctoral research fellow (2010), I again focused on the role of receptor-like kinases in root development and asymmetric cell division (De Smet and Beeckman, Nat Rev Mol Cell Biol, in press; Den Herder et al., 2010, Trends Plant Sci 15:600-607).
