Research Interest

Within my research team, we study the molecular interactions between bacteria and virusses on how they infect their host plants.

 

  • We study the role of the SUMO E3 ligase SIZ1 on plant immunity via the immune receptor SNC1 and how SIZ1 affects plant growth via the ubiquitin E3 ligase COP1.
  • We study Block Rot disease caused by the bacterium Xanthomonas in Arabidopsis en how its effectors control the infection process, e.g.. its effector XopD acts as SUMO protease and contributes to tolerance to Xanthomonas.
  • Together with Prof. dr. M. Prins we are studying the Geminivirus-tomato interaction. Geminiviruses are ssDNA virusses that need the host DNA replication machinery for replication of the viral DNA. We are studying the protein-protein interactions between the essential viral protein REP and the host DNA replication machinery.

 

SUMO as suppressor of the Plant innate immunity

Key to the survival of any organism is the ability to defend itself. This defense response  relies on transcriptional reprogramming in the first hours after invasion, and often results in programmed cell death and the accumulation of anti-microbial compounds. Our research indicates that protein modification SUMO is essential as 'hand-break' on plant defense in Arabidopsis, but also a growth regulator via the ubiquitin E3 ligase COP1. Currently, we are studying how SUMO conjugation affects immunity and growth.

 
Our group revealed that SUMO acts as suppressor of these plant immunity (Van den Burg et al., 2010). The SUMO E3 ligase SIZ1 controls accumulation of the  hormone Salicylic acid. We demonstrated that this involves conjugation of the SUMO1 and -2. SUMO is as a protein modifier that is coupled to other proteins. The targets for SUMO conjugation are predominantly nuclear proteins. We study the effect of SUMO on gene regulation via SIZ1.


We have now proposed an evolutionairy model explaining the birth-and-death of the SUMO paralogs in the model plant Arabidopsis (Hammoudi et al., 2016). This model revealed that paralog SUMO3 only recently evolved in Brassicaceae, while  SUMO5 appears to be of ancient origin, close the WGT-gamma event (near the base of the dicot species redation). Our model also reveals how the speudogenes SUMO4/6 have retained an 'archtype' SUMO identity in other plant species.

 

Durable resistance against Black Rot in Brassica.

Black Rot, caused by the bacterium Xanthomonas campestris pv. campestris (Xcc), remains a devastating disease on Brassica crops worldwide. Xcc is one of few foliar bacterial pathogens that colonize its host through organs on the leaf margins, called hydathodes, which stand in direct contact with the leaf vasculature. After dissolution of the hydathode, Xcc colonizes the xylem vessels. Recent studies have shown that Xcc proliferates in the hydathode and subsequently colonizes the vasculature in a type III secretion-dependent manner, indicating that the epithem tissue in the hydathode mounts an immune response.

 

Hydathode gutation forms the entry point of the bacteria

We have developed a ‘hydathode guttation’  entry assay for the bacteria. This allows us to disect the genetic basis for bacterial ingress. We study both the mechanisms that allow bacterial ingress and provide resistance to the host plant in these hydathodes. For genetic screens, we have optimized a bioluminescent reporter, which allows us to follow bacterial invasion via hydathodes and subsequent systemic spread in the vasculature.

SUMO wrestling determines expression of plant defense genes

 

  • There are always possibilities for students to perform a practical period (minimal 4 months) in our Lab - Please inquire for specific projects currently available.

 

Background

  • The SUMO E3 ligase SIZ1 acts both in the SNC1 immune pathway and the COP1 growth pathway. The latter protein is a ubiquitin E3 ligase, while the first protein is an immune receptor of the TNL type. In our lab we try to use genetics approaches combined with biochemistry to study how SIZ1 affects growth and immunity.

Techniques

  • Depending on the length of the practical training period, projects involve a diverse array of techniques: protein isolation and immunoblotting, SUMO conjugation assays, analysis of mutant plants (including genotyping), real-time PCR, protein-protein interactions assays, like yeast 2-hybrid, BiFC, split luciferase.

Exploring basal resistance against Xanthomonas in Arabidopsis

 

Background

  • Black Rot is a devastating disease in Brassica crops (e.g. cabbage, cauliflower). It is caused by the bacteria Xanthomonas campestris pv. campestris (Xcc). Xcc enters the plant through specialized organs on the leaf margin, called hydathodes, and spreads from there through the vasculature. In our group we use Arabidopsis thaliana, a member of the Brassicaceae family, as model system to study this disease. This allows us to make use of the molecular and genetic tools that exist for Arabidopsis.

Techniques

  • Depending on the length of the training period, projects involve a diverse array of techniques: tri-parental mating, Golden gate cloning, Xanthomonas disease assays, ROS burst measurements, real-time PCR, staining with Trypan blue, western blotting to detect activation of kinases, working with the model plant Arabidopsis etc.
