title: [Site of fidget gene action and its interaction with the ocular retardation gene in cultured mouse embryo retinas].
abstract: The eye rudiments of 10 and 11 days old mouse embryos of the genotypes +/+ +/+, fi/fi +/+, +/+ or/or, fi/fi or/or and 11 days old embryos of the genotype fi/+ or/+ were cultivated in vitro during 24, 48 and 72 hrs. The expression of the fi gene was shown in the cells of the cultivated fi/fi +/+ retina: its proliferative activity was inhibited. The fi gene was not active in the cells of the developing lens and the anomalies of the latter in homozygotes arose secondarily, due to the inhibition of growth of the retinal rudiment. The fi and or genes interacted synergically in the cultivated fi/fi or/or retina, thus resulting in the marked inhibition of its mitotic activity. This suggests that both the genes act in the retinal cells and, apparently, affect different links of the biochemical chain of events in the preparation of DNA replication.
