Summary
Geisenheim University, Germany, is inviting applications for a PhD Candidate / Research Assistant (65%) position in plant virus analysis using RNA sequencing (RNA-seq). The doctoral project will use Oxford Nanopore-based long-read RNA sequencing and bioinformatics to improve the diagnosis and genomic characterization of Grapevine Pinot Gris Virus (GPGV).
The project will investigate GPGV infections in German wine-growing regions, including virus detection, genome reconstruction, genetic diversity, symptom development, and possible natural transmission through animal vectors. The successful candidate will work at the intersection of molecular biology, transcriptomics, bioinformatics, virology, and applied plant science.
