Abstract

Four deletion mutantDictyostelium myosin II heavy chain genes, MyΔ824-941 (Δ1/ 3S2), MyΔ934-1454 (ΔS2), MyΔ934-1194 (ΔS2-1) and MyΔ1 157–1454 (ΔS2-2), were transformed by standard electfoporation into mhcA-cells (T-null), a mutantDictyostelium cell devoid of endogenous myosin II heavy chain gene. The growth, development and formation of fruiting bodies of cells expressing those mutant myosin II s under suspension culture were investigated by comparison with the wild type cell. The results indicate that internal deletion of myosin II affeds the growth and development ofDictyastelium. Furthermore, the longer the length of deletion, the more serious the defect in phenotype.
