Low temperatures effected Xcc swarming motility. a Swarming motility of Xcc wild- type strain on rich YEB medium plates at 28 °C and 15 °C after 3 days. b The characteristic image of Xcc colonies edge morphology were captured by inverted microscope at 28 °C and 15 °C. c Microscopic images of Xcc edge expressing green fluorescent protein. Images were obtained under an inverted fluorescence microscope at 100X magnification
