COVER A group of about 30 tadpole-stage Ciona intestinalis embryos 12 to 14 hours after fertilization. The embryos were electroporated at the one-cell stage with a fusion gene containing the 5' cis-regulatory region of the Brachyury gene attached to a green fluorescent protein (GFP) reporter gene. The Brachyury regulatory DNA directs GFP expression in the notochord cells of the tadpole tails. 2157 [Image: Mei Wang]
