SRP328812 PRJNA747755 In planta transcriptome and proteome profiles of Spongospora subterranea illuminates regulatory principles underlying host-pathogen interaction Spongospora subterranea is an obligate biotrophic pathogen, causing a tremendous economic loss in the potato industry. Currently, there are no effective chemical or biological strategies for the control of S. subterranea. Understanding the gene regulation of pathogens in their host is dependent on multidimensional datasets. To further our understanding of S. subterranea biology during infection, we characterized the transcriptome and proteome of the pathogen inside the susceptible and resistant potato cultivars.
