Biased inheritance of the protein PatN frees vegetative cells to initiate patterned heterocyst differentiation.

Proceedings of the National Academy of Sciences of the United States of America - 18 Sept 2012

Risser Douglas D, Wong Francis C Y, Meeks John C

Abstract excerpt

Heterocysts, cells specialized for nitrogen fixation in certain filamentous cyanobacteria, appear singly in a nonrandom spacing pattern along the chain of vegetative cells. A two-stage, biased initiation and competitive resolution model has been proposed to explain the establishment of this spacing pattern. There is substantial evidence that competitive resolution of a subset of cells initiating differentiation...
