Temporospatial hierarchy and allele-specific expression of zygotic genome activation revealed by distant interspecific urochordate hybrids

robusta / savignyi reciprocal crosses after dechorionation. “Gene expression and regulatory profiles revealed that the initiation of ZGA in Ciona began at the 8-cell stage, with the minor wave mainly occurring from the 16- to 32-cell stage and the major wave from the 64- to 112-cell stage during ascidian embryogenesis”
