The Leipzig University is inviting applications for a PhD position in Plant Biology within the Plant Physiology group at the Institute of Biology. This doctoral opportunity is designed for motivated researchers interested in molecular plant science, algae biology, cellular adaptation, and environmental stress responses. The position is funded by the German Research Foundation (DFG) and offers an opportunity to participate in an interdisciplinary research project investigating how microscopic algae survive extreme environmental conditions. The successful candidate will study the transformation of algal zygotes into highly resistant dormant structures known as zygospores, using molecular, genetic, physiological, and biochemical approaches.

The PhD position in Plant Biology at Leipzig University provides an excellent opportunity for researchers interested in molecular plant science, microalgae biology, and environmental stress adaptation. Supported by DFG funding, the project combines advanced laboratory methods with fundamental biological questions about how photosynthetic organisms survive challenging conditions. Candidates with backgrounds in biology, biochemistry, molecular biology, or related disciplines should consider applying before the August 2026 deadline.

PhD Research Project Overview

Understanding How Microalgae Survive Environmental Stress

Microalgae are essential primary producers in aquatic and terrestrial ecosystems. They contribute significantly to global carbon cycling and support many ecological processes. During sexual reproduction, several microalgae species produce zygotes that develop into resistant dormant spores called zygospores. These specialized structures have an exceptional ability to survive harsh environmental conditions, including:

• Freezing temperatures
• Water loss and desiccation
• Other forms of abiotic stress

This PhD project focuses on understanding the biological processes behind the zygote-to-zygospore transition in the unicellular model organism Chlamydomonas reinhardtii. Researchers will investigate how a photosynthetic eukaryotic cell changes its metabolism, genetic activity, and physiological state to become a dormant and highly resistant spore. The findings may provide important insights into cellular survival strategies, evolutionary adaptation, and plant stress biology.
