Myxococcus xanthus is able to move over solid surfaces as large coordinated groups (Social motility) or as single isolated cells (Adventurous motility). While S-motility was shown to rely on polar Type-IV pili in the early 2000s, the mechanism of A-motility has long remained mysterious because it occurs in absence of detectable extracellular organelles. In the past, many models have been proposed to explain A-motility. In recent years, with the advent of high-resolution fluorescence microscopy and phylogenomics, it has been possible to identify the A-motility machinery and propose a motility mechanism. In this chapter, we discuss the state-of-the-art in A-motility research and future directions to decipher this long mystery of modern bacteriology read more ...
