title: Characterization of developmental autolysis in myxobacterial fruiting body morphogenesis with profiling of amino acids using capillary electrophoresis method.
abstract: Capillary electrophoresis equipped with Laser-induced fluorescence (CE-LIF), combining with micro-culture technique was employed to determine extracellular amino acids in single myxobacterial fruiting body morphogenesis. The result showed that in the early aggregation stage, there was a remarkable increase of extracellular amino acids, which was produced by developmentally induced autolysis. The amino acids were then consumed by the vegetative cells in aggregation stage. In the following developmental events, the extracellular amino acids were kept at low level, which indicated that in the stages of fruiting body formation and myxospore development, there was no further cell autolysis. Using this novel method may provide detailed insight into the mechanisms of the developmental phenomena.
