His fundamental interest is how the cellular dynamics contributes to the overall fitness of the plants in natural habitats.

Jana Ordon

PhD Student
Jana comes from Germany and studied biology at Martin-Luther University Halle-Wittenberg. During her bachelor’s thesis she generated and tested a genome editing toolkit, which was then used to investigate the importance of a Resistance gene cluster in autoimmunity and pathogen defence during her master’s thesis (Ordon et al., Funct Integr Genomics 2019). She started her PhD in October 2018 and mainly focuses on the role of the plant innate immune system in the establishment of the root microbiota.

Anna Lisa Roth

Technical assistant
Anna Lisa comes from Germany and is working as a technical assistant. She is working on the Arabidopsis root microbiota and has a wide range of responsibilities including laboratory organization and maintenance of microbial culture collections. She supports the scientific staff for bacterial community screening and DNA preparation. Simone and Anna Lisa are working together.

Isabel Saur

Isabel received a BSc degree at the University of Applied Sciences in Esslingen am Neckar, Germany. Part of this work included the characterization of the ‘cold induced anther protein in rice’ and ‘CLE peptides involved in the regulation of nodulation in Medicago trancatula’. Her PhD work at The Australian National University in Canberra, Australia, in the group of John Rathjen focused on the Pto/Prf immune receptor complex and a novel receptor required for bacterial cold shock protein (or csp22)-mediated immunity. Isabel now focuses on the role of Blumeria graminis effectors recognized by barley MLA NLRs.

Julien Thouin

Julien did his PhD in the group of Hervé Sentenac at the Biochemistry & Plant Molecular Physiology (BPMP) Joint Research Unit in Montpellier, France, where he studied the molecular dialogue underpinning the establishment of the nitrogen-fixing symbiosis between rhizobia and legumes. He specifically focused his attention on the ionic channels involved in electrical and calcium signaling at the root hair plasma membrane in Medicago truncatula. Julien joined the PSL group in February 2019, where he is now interested in identifying the Rhizobiales mechanisms involved in microbiota colonisation and persistence on plant roots.

Kathrin Wippel

Kathrin is from Germany and did her PhD in Molecular Plant Physiology at University of Erlangen, focusing on the molecular players of nutrient exchange at the maize/Ustilago maydis interface. During her postdoctoral time in the lab of Sharon Long at Stanford University, USA, she worked on stress response and transcriptional regulation in Sinorhizobium meliloti during symbiosis with Medicago sativa. She joined the lab in 2017 to decipher the role of plant exudates on the bacterial community associated with the legume Lotus japonicus.

Makoto Yoshikawa-Maekawa

Makoto Yoshikawa-Maekawa comes from Hyogo, Japan. She is studying how barley NLR-type immune receptors recognize cognate effectors of the barley powdery mildew fungus and initiate immune signaling.
