We compared lipid droplet distribution in embryos laid by wild-type flies (Oregon-R) or by flies transheterozygous for two weak alleles of Dhc64C, the gene for the heavy chain of cytoplasmic dynein (Gepner et al. 1996). Fixed embryos were stained for lipid droplets as described in Welte et al. 1998. In both genotypes, droplets accumulate in the center, towards the plus end of microtubules, in early cycle 14 (not shown); in Dhc64C mutants, they fail to redistribute towards the minus ends (the periphery) during gastrulation.
