  • Self-Driven Phase Transitions Drive Myxococcus xanthus Fruiting Body Formation. [Journal Article]
    Phys Rev Lett 2019; 122(24):248102Liu G, Patch A, … Shaevitz JW
  • Combining high-resolution single cell tracking experiments with numerical simulations, we show that starvation-induced fruiting body formation in Myxococcus xanthus is a phase separation driven by cells that tune their motility over time. The phase separation can be understood in terms of cell density and a dimensionless Péclet number that captures cell motility through speed and reversal frequen…
  • Reclassification of 'Polyangium brachysporum' DSM 7029 as Schlegelella brevitalea sp. nov. [Journal Article]
    Int J Syst Evol Microbiol 2019Tang B, Yu Y, … Ding X
  • Strain DSM 7029, isolated from a soil sample in Greece, can produce antitumour glidobactins, and has been found, as a heterologous host, to produce useful nonribosomal peptide synthetase-polyketide synthase hybrid molecules known as epothilones. This strain was originally named 'Polyangium brachysporum' of the family Polyangiaceae and the order Myxococcales. However, phylogenetic analysis of the …
  • Survey of Biosynthetic Gene Clusters from Sequenced Myxobacteria Reveals Unexplored Biosynthetic Potential. [Journal Article]
    Microorganisms 2019; 7(6)Gregory K, Salvador LA, … Stevens DC
  • Coinciding with the increase in sequenced bacteria, mining of bacterial genomes for biosynthetic gene clusters (BGCs) has become a critical component of natural product discovery. The order Myxococcales, a reputable source of biologically active secondary metabolites, spans three suborders which all include natural product producing representatives. Utilizing the BiG-SCAPE-CORASON platform to gen…
  • The effects of chemical and organic fertilizer usage on rhizosphere soil in tea orchards. [Journal Article]
    PLoS One 2019; 14(5):e0217018Lin W, Lin M, … Lin W
  • Sustainable agriculture is an important global issue. The use of organic fertilizers can enhance crop yield and soil properties while restraining pests and diseases. The objective of this study was to assess the effects of long-term use of chemical and organic fertilizers on tea and rhizosphere soil properties in tea orchards. Inductively coupled plasma mass spectrometry (ICP-MS) and high-through…
  • A TonB-dependent transporter is required for secretion of protease PopC across the bacterial outer membrane. [Journal Article]
    Nat Commun 2019; 10(1):1360Gómez-Santos N, Glatter T, … Søgaard-Andersen L
  • TonB-dependent transporters (TBDTs) are ubiquitous outer membrane β-barrel proteins that import nutrients and bacteriocins across the outer membrane in a proton motive force-dependent manner, by directly connecting to the ExbB/ExbD/TonB system in the inner membrane. Here, we show that the TBDT Oar in Myxococcus xanthus is required for secretion of a protein, protease PopC, to the extracellular mi…
  • sRNA-pathway genes regulating myxobacterial development exhibit clade-specific evolution. [Journal Article]
    Evol Dev 2019; 21(2):82-95Chen IK, Satinsky BM, … Yu YN
  • Small non-coding RNAs (sRNAs) control bacterial gene expression involved in a wide range of important cellular processes. In the highly social bacterium Myxococcus xanthus, the sRNA Pxr prevents multicellular fruiting-body development when nutrients are abundant. Pxr was discovered from the evolution of a developmentally defective strain (OC) into a developmentally proficient strain (PX). In OC, …
