Abstract

Due to their resistance to chemical treatments, the resting spores of Synchytrium endobioticum the causal agent of potato wart disease pose a particular threat in the form of long-term contamination of residual soil and arable land. They show a wide spectrum of characteristic morphological phenotypes and are therefore a particular challenge in the reliable diagnosis of potato wart. In addition to addressing them as Synchytrium endobioticum, assessing the viability of the resting spore based on microscopic examination is challenging. The reference image collection is intended to provide decision support and training material for diagnostic laboratories. Exemplary images of resting spores/sporangium of different categories are evaluated and special characteristics are highlighted. The reference image collection is available on the homepage of the National Reference Laboratory of the Julius Kühn Institute for registered users.
