S-(3, 4-dichlorobenzyl) isothiourea (A22) has been reported to specifically inhibit the function of MreB, an actin-like protein in rod-shaped bacteria. This study investigated the role of A22 in cyanobacterium Anabaena sp. strain PCC 7120, which can form nitrogen-fixing heterocysts under combined-nitrogen deprivation. Results indicated that A22 could inhibit cell growth, cause abnormal cellular morphology and bring about asymmetric cell division and irregular DNA distribution. However, A22 has little effect on heterocyst formation. An A22-resistant mutant named C23 was isolated by growing cells on A22-containing plates. It had normal appearance of cell shape, division and DNA content when treated by A22. However, this mutant retained a wild-type allele of mreB.
