Abstract Bacterial pathogens from the genus Pectobacterium cause soft rot in various plants, and result important economic losses worldwide. We understand much about how these digest their hosts protect themselves against plant defences, as well some regulatory networks processes. However, spatiotemporal expression of genome‐wide infection remains unclear, although researchers analysed this phytopathogens. In present work, comparing transcriptome profiles cellular with growth minimal rich media, RNA‐Seq analyses revealed that differentially expressed genes (log 2 ‐fold ratio ≥ 1.0) cells carotovorum subsp. PccS1 recovered at a series time points after inoculation host vivo covered approximately 50% genome. Based on dynamic changes infection, significantly 2.0) were classified into five types, main pattern for carbohydrate metabolism underlying processes was identified. The results are helpful to our understanding inducement environmental adaption . addition, demonstrate maceration caused by is due depression callose deposition resistance pathogenesis‐related superlytic ability pectinolytic enzymes produced PccS1, rather than promotion cell death elicited T3SS bacteria described previous work.
