  1. copia LTR-CAT in a transformed strain (9-3) made wild type or heterozygous for dominant mutant alleles of genes known to affect chromatin structure [LOW-lightening of white; HDAC 1326, HDAC 1328-Histone Deacetylase; E(z)61, E(z)28-Enhancer of zeste; Psc25-Posterior sex combs; Sxlfl-Sex lethal or hemizygous for the X-linked recessive mof1(males absent on first) allele. A slight but significant decrease in activity was observed in strains heterozygous for the dominant mutant HDAC 1326, HDAC 1328, E(z)28and Psc25alleles. A highly significant increase in activity was observed in the strain hemizygous for the recessive mutant mof1allele
