iii) The hetR gene encodes a repressor of heterocyst formation.
The hetR gene encodes an activator of heterocyst formation.
The hetR gene encodes a protein with no effect on heterocyst formation. B) In wild-type Anabena cells, the patS-gfp transcriptional fusion is expressed in heterocysts but
not in the photosynthetic cells. In cells that have the plasmid containing hetR, patS-gfp is NOT
expressed in either heterocysts or photosynthetic cells. From this data, indicate what you can
conclude regarding how the hetR gene product affects heterocyst development....
