is a highly contagious respiratory bacterial veterinary pathogen. In this study the contribution of the transcriptional regulators BvgR, RisA, RisS, and the phosphorylation of RisA to global gene regulation, intracellular cyclic-di-GMP levels, motility, and biofilm formation were evaluated. Next Generation Sequencing (RNASeq) was used to differentiate the global gene regulation of both virulence-activated and virulence-repressed genes by each of these factors. The BvgAS system, along with BvgR, RisA, and the phosphorylation of RisA served in cyclic-di-GMP degradation. BvgR and unphosphorylated RisA were found to temporally regulate motility. Additionally, BvgR, RisA, and RisS were found to be required for biofilm formation.
是一种具有高度传染性的呼吸道细菌性兽医病原体。在本研究中，评估了转录调节因子BvgR、RisA、RisS以及RisA的磷酸化对全局基因调控、细胞内环二鸟苷酸水平、运动性和生物膜形成的作用。使用下一代测序（RNA测序）来区分这些因素对毒力激活基因和毒力抑制基因的全局基因调控。BvgAS系统以及BvgR、RisA和RisA的磷酸化参与环二鸟苷酸的降解。发现BvgR和未磷酸化的RisA可暂时调节运动性。此外，发现生物膜形成需要BvgR、RisA和RisS。
