Introduction

Lay-Sun Ma is an Associate Research Fellow at the Institute of Plant and Microbial Biology (IPMB), Academia Sinica, Taiwan, where she has been actively engaged in advanced research since beginning her Ph.D. studies there in 2006, which provided her with a strong academic foundation. Her professional journey spans prestigious institutions globally, including post-doctoral fellowships at the Max Planck Institute for Terrestrial Microbiology in Germany (2014–2018) and Academia Sinica (2011–2014), as well as a visiting scientist role at Imperial College London in 2012. 

In 2018, she established a UMAydis@IPMB research group dedicated to exploring plant-microbe interactions, using the maize-Ustilago maydis pathosystem as a model. Her team studies the functions of extracellular effector proteins in the smut fungus Ustilago maydis and their impact on fungal pathogenicity, while also probing the apoplastic defense strategies of maize.

The UMAydis@IPMB research laboratory brings together a diverse team of scientists from Malaysia, Vietnam, India, Indonesia, and Taiwan. It currently consists of one postdoctoral researcher, three Ph.D. students, one Master's student, and two research assistants. We warmly welcome self-motivated individuals—whether undergraduate or graduate students, interns, or postdoctoral fellows—with a deep passion for science to join us in unraveling the complexities of pathogenic biotrophs. Driven by a shared mission to safeguard and sustain the global food supply, our work seeks to understand how these organisms threaten crop production.


Research Topics

Our research interests

To uncover the invasion strategies of U. maydis and prevent the onset of initial infection, we focus on studying effectors located at the interaction interface of maize-U. maydis, aiming to reveal the following mechanisms:

  • Sensing and adaptation mechanisms
  • Effector regulatory mechanisms
  • Mechanisms by which fungal cells suppress apoplastic immunity
  • Maize defense mechanisms
