Effects of base analogues 5-bromouracil and 6-aminopurine on development of zebrafishDanio Rerio
摘要
Abstract
Zebrafish (Danio rerio) genetic screens allow isolation of a wide array of problems in vertebrate biology. The effects of base analogues 5-bromouracil and 6-aminopurine on the development of zebrafish embryos are reported for the first time in this study. The early development of the zebrafish embryos was little affected by 5-bromouracil and 6-aminopurine
while the late development (organogenesis) was significantly impaired. Embryos exposed to 5-bromouracil mainly showed curled tail
wavy body
golden pigmentation and the mouth with protruding lower jaw. 6-aminopurine-treated embryos had defective anterior structures
curled tails and wavy body. RAPD analysis showed that the majority of 5-bromouracil- and 6-aminopurine-treated larvae and fish shared banding patterns in common with the control
suggesting that most mutagenesis induced by these agents are point mutations. However
some fish derived from 5-bromouracil-treated embryos had golden (gol) pigmentation; and RAPD analysis revealed that their band patterns differed from those of the control. Possibly
5-bromouracil can occasionally cause relatively extensive changes in the fish genome. The results of this study may provide valuable help for detailed studies of mutagenesis.
