Current Research

The laboratory studies the mechanisms that regulate root growth and development. Our research exploits the model plant Arabidopsis thaliana which represents one of the best experimental systems to study root developmental processes in higher plants. Arabidopsis is ideally suited to perform molecular genetic, cell biology and transgenic studies and has facilitated the isolation and characterisation of genes such as AUX1 and AXR4 that regulate processes such as root gravitropism and lateral root development (Bennett et al, 1996; Dharmasiri et al, 2006).

We have recently adopted an Integrative Systems Biology based approach to study root growth and development (Swarup et al 2005). Our laboratory is part of The Centre for Plant Integrative Biology (CPIB; www.cpib.info ), a £9.2 m BBSRC/EPSRC funded Centre for Integrative Systems Biology that aims to create a virtual root model. Our Systems Biology approach embraces disciplines such as mathematics, engineering, computer science, as well as plant science, enables researchers to study root development at multiple physical and temporal scales (e.g. molecular, cellular and organ levels) and help our research become more quantitative, integrative and predictive.

Areas of Interest

Our current research falls into 3 areas:-

  • Root Developmental Biology
  • Root Systems Biology

Root Developmental Biology Polar auxin transport is critical for plant growth and development. Auxin moves between plant cells through a combination of membrane diffusion and influx/efflux carrier-mediated transport. Our initial research led to the isolation and characterisation of AUX1, the first auxin transport protein to be described in plants. Subsequent research has examined the importance of AUX1, and auxin transport generally, during primary and secondary root development. Recent studies addressing the regulation of AUX1 trafficking has identified a novel ER protein termed AXR4 which is required for AUX1 plasma membrane localization.

Root Systems Biology

The laboratory has recently embraced an Integrative Systems Biology based approach in collaboration with the US modeller Eric Kramer to study the hormonal regulation of root growth and development. This work has led to the creation of The Centre for Plant Integrative Biology (CPIB) at the University of Nottingham. The £8.5m BBSRC funded Centre aims to create a virtual root which will serve as an exemplar for using Integrative Systems Biology (ISB) to model multi-cellular systems. CPIB researchers ultimately aim to integrate our virtual root with other international projects that model shoot development, leading to a generic computer model of a plant which will be used to advance crop and plant science (see www.cpib.info for further details).
