Potato plants were inoculated with a strain of Potato spindle tuber viroid propagated in tomato plants for three cycles. Transcriptome of leaves was sequenced at three time points, and changes in expression of genes were observed. Genes with lower expression at later time points are mainly associated with regulation of cell cycle and microtubule-based processes, which indicates suppression of growth and development. Additionally, down-regulated genes are associated with general metabolism and metabolism-related processes, suggesting initiation of dormancy and growth delay.

Mainly, however, propagation of Potato spindle tuber viroid in tomato plants results in mitigation of symptoms after inoculation of potato with the same viroid.
