Transcriptome Characterization and Gene Changes Induced by in Sweetpotato Roots.

Sweetpotato () is an important root crop that is infected by in both seedling and root stages, causing irregular black or brown disease spots and root rot and canker. This study aims to use RNA sequencing technology to investigate the dynamic changes in root transcriptome profiles between control check and roots at 6 h, 24 h, 3 days, and 5 days post-inoculation (hpi/dpi) with . The results showed that the defense reaction of sweetpotato could be divided into an early step (6 and 24 hpi) without symptoms and a late step to respond to infection (3 and 5 dpi).
