Abstract/OtherAbstract:
Per-ARNT-Sim (PAS) domains are important signaling modules that possibly monitor changes in various stimuli such as light. For the majority of PAS domains that have been identified by sequence similarity, the biological function of the signaling pathways has not yet been experimentally investigated. Thirty-three PAS proteins were discovered in Xanthomonas campestris pv. campestris (Xcc) by genome/proteome analysis. Thirteen PAS proteins were identified as contributing to light signaling and Xcc growth, motility or virulence using molecular genetics and bioinformatics methods. The PAS domains played important roles in light signaling to regulate the growth, motility and virulence of Xcc. They might be regulated by not only light quality (wavelength) but also quantity (intensity) as potential light signaling components. Evaluating the light wavelength, three light-signaling types of PAS proteins in Xcc were shown to be involved in blue-light signaling, tricolour (blue, red and far-red) signaling or red/far-red signaling. This showed that Xcc had evolved a complicated light signaling system to adapt it to a complex environment.
