A heritable iron memory enables decision-making in Escherichia coli
S Bhattacharyya, N Bhattarai… - Proceedings of the …, 2023 - National Acad Sciences
The importance of memory in bacterial decision-making is relatively unexplored. We show
here that a prior experience of swarming is remembered when Escherichia coli encounters a …
