Visualization of Twitching Motility and Characterization of the Role of the PilG in Xylella fastidiosa
April 8th, 2016
In this study, a nano-microfluidic flow chamber was employed to visualize and functionally characterize the twitching motility of Xylella fastidiosa, a bacterium that causes Pierce's disease in grapevine.
The over goal of this protocol is to functionally characterize the genes responsbile for the twitching motility of bacteria using a nano microfluidic flow chamber integrated with a time-lapse image recording system.This method can help answer key questions about a bacteria phenotype and associated gene function, such as the twitching motility of bacteria.The main advantage of this technique is that it provides a special and a tempered observation for aggregation migration of individual cells and populations.Demonstrating this procedure will be Dr.Xiangyang Shi, a post-doc from my laboratory.Using a standardized deletion strategy, grow Temecula wild-type Xylella fastidiosa, grow pilG deletion mutants, and grow the complimentary strain all on PD2 medium agar plates.Incubate the bacteria at 28
