在筛选识别斑马鱼眼睛突变体时,我们分离出good effort(gef)突变体。胚胎视网膜的特征是在受精后的前2天内,视神经原基成功形成,视网膜发育正常。然而,突变的视网膜不能继续生长。用吖啶橙法和TUNEL标记法对杂合杂交胚胎进行细胞死亡分析。与野生型胚胎相比,突变体胚胎在2 dpf时发现了更多的tunel阳性和吖啶橙标记的死亡细胞。因为这个时间早于任何可观察到的大体形态差异,这种细胞死亡很可能是造成大体形态缺陷的原因。减数分裂定位将斑马鱼9号染色体上的突变间隔定位为1兆碱基间隔。
In a screen to identify zebrafish eye mutants, we isolated thegood effort(gef) mutant. The retina ofgefembryos is characterized by the successful initiation of the optic primordium and normal retinal development over the first 2 days post fertilization (dpf). The mutant retina, however, fails to continue to grow. Embryos fromgefheterozygous incrosses were analyzed for cell death by acridine orange and by TUNEL labeling at 2 dpf. Significantly more TUNEL-positive and acridine orange-labeled dying cells were found ingefmutant embryos at 2 dpf relative to wild-type embryos. Because this time was earlier than any observable gross morphological differences, this cell death was likely the cause of the gross morphological defects. Meiotic mapping localized the mutation interval to a one-megabase interval on zebrafish chromosome 9.
