SIPS Plant Pathology & Plant-Microbe Biology Section

We are making new scientific discoveries about the interactions between plants and microbes and developing innovative solutions to address the challenges of 21st century agriculture across the globe. We offer students and postgraduate scholars unparalleled opportunities to study the origins and consequences of plant diseases. At the same time, we provide essential information to decision-makers, including agriculture producers, educators, policymakers, home gardeners, and local communities. Learn more about the history of our section and the vision of our school.

Diversity of Pathogens

Fungi & oomycetes

Fungi and oomycetes represent some of the world most devastating plant pathogens and important plant symbionts as well as being critically important part of the plant and soil microbiome. Our faculty, staff and students include experts in fungal and oomycete taxonomy, molecular interactions, ecology and control.

Diversity of Pathogens

Bacteria

Bacteria are the sources of many important diseases. Our faculty, staff and students are experts in the control of bacterial disease as well as the fundamental interactions at a molecular level that control susceptibility and resistance.

Diversity of Pathogens

Viruses

Viruses are important pathogens, studied by several of our research groups. Areas of investigation include interactions with transmitting insects, diagnosis of viral diseases and pathogen control.

Diversity of Pathogens

Nematodes

Several types of nematodes including the Golden Nematode represent serious threats to New York state agriculture. Researchers affiliated with Plant Pathology and Plant-Microbe Biology are experts the characterization of molecular virulence determinants as well as the biology and ecology of nematode pathogens.

Cross-cutting themes & tools

From fundamental biology to sustainable disease management with cutting-edge tools of digital agriculture, to pathogen management in international settings, research in Plant Pathology and Plant-Microbe Biology addresses many important questions and needs

Graduate field of PPPMB

Graduate field of plant pathology and plant-microbe biology: Students interested in obtaining an M.S. or Ph.D. degree in this field can select among three concentrations:

  • Plant pathology
    Biology and integrated management of plant disease organisms

  • Fungal and oomycete biology
    Fungi and oomycetes including genomics, ecology and systematics

  • Plant-microbe biology
    Molecular genetics of interactions between microbes and plants

Undergraduate — plant sciences major

Undergraduates majoring in the plant sciences can choose to concentrate in plant pathology and plant-microbe biology, preparing them for careers related to disease and pest management, and for graduate study in plant pathology, mycology and the biology of plant-microbe interactions. 

Undergraduate — Fungal Biology Minor

Cornell is one of few places in the United States where students can receive in-depth training on fungi and their impacts. Undergraduate students in diverse majors can add a minor in fungal biology that provides a deep knowledge of fungi and expands their versatility in the workplace.

Undergraduate research — Summer Research Scholars

The Summer Research Scholars Program for undergraduates is offered by Cornell AgriTech in Geneva, New York. Undergraduate students participate in exciting research projects in one of three disciplines including plant pathology and plant-microbe biology.

Undergraduate research — Microbial Friends & Foes

The Microbial Friends & Foes undergraduate research experience is sponsored by the Cornell Institute of Host-Microbe Interactions and Disease. Participants are placed in host labs at Cornell working on many different aspects of microbial interactions with plants and animals.

Undergraduate research — other

The Office of Undergraduate Research provides information about exploring the wealth of research opportunities at Cornell.

The Honors Program in Biological Sciences is designed to offer advanced training in laboratory and field research through the performance of an original research project under the direct guidance of a member of the Cornell faculty.

 

Master of Professional Studies

Our MPS programs are one-year, course-based degrees, ideal for individuals interested in in-depth study of the issues and advancements in plant and soil sciences. Choose from specializations in Controlled Environment Agriculture, viticulture, public garden leadership, hemp science, plant protection, geospatial applications and more.
