Expression of identified two-component systems in K. pneumoniae Kp13 with distinct environmental stimuli. Expression values are represented as log₂(fold-change) of the condition compared to the PB condition (log₂(abiotic condition/PB condition). Thus, a positive log₂FC value indicates higher expression of the gene in face of abiotic stress to which it was subjected. For each system, the sensor protein is highlighted in bold, while the regulatory component is in normal formatting. The main functions and signals perceived by each system are shown according to literature mining
