Cool temperature triggers HktS-HktR signaling to promote RpoD-mediated activation of T3SS virulence in Pseudomonas syringae pv. actinidiae
Kiwifruit bacterial canker (KBC), caused by Pseudomonas syringae pv. actinidiae (Psa), severely impacts kiwifruit production. Previous studies show that Psa exhibits enhanced virulence under cool temperatures; however, the underlying regulatory mechanisms remain unclear. Given the crucial role of histidine kinases (HKs...
