Type IV pili (TFP) are known to be functionally related cell motilities and natural transformation in many bacteria. However, the molecular ecological functions of TFP have rarely been reported for photosynthetic cyanobacteria. Here, by labeling model cyanobacterium Synechococcus elongatus PCC 7942 (Syn7942), we quantitatively characterized its driven twitching motility situ at single-cell level. We found an oscillating pattern accordance with light dark periods during light-dark cycles, which is correlated positively efficiency. further showed that internal circadian clock plays important role regulating TFP, also supported evidences level tracking expression 16 TFP-related genes. This study adds a detailed picture toward gap between relations regulations Syn7942.
