“…A Hox cluster containing 11 Hox genes was found in the genome of Lottia gigantea [123] and further in two genomes of scallop Chlamys farreri [124] and Patinopecten yessoensis [125,126]. Whole-genome analysis of the Hox gene family of the mussel M. coruscus revealed that 11 Hox genes are evenly distributed within a single chromosome [127]. Candidate orthologues of ten Hox genes, except for Hox7, as in C. gigas [50], and three ParaHox sister complex genes were identified from the transcriptome of Dreissena rostriformis [128].…”

This comprehensive review presents a comparative analysis of early embryogenesis in Protostomia and Deuterostomia, the first of which exhibit a mosaic pattern of development, where cells are fated deterministically, while Deuterostomia display a regulatory pattern of development, where the fate of cells is indeterminate. Despite these fundamental differences, there are common transcriptional mechanisms that underline their evolutionary linkages, particularly in the field of functional genomics. By elucidating both conserved and unique regulatory strategies, this review provides essential insights into the comparative embryology and developmental dynamics of these groups. The objective of this review is to clarify the shared and distinctive characteristics of transcriptional regulatory mechanisms. This will contribute to the extensive areas of functional genomics, evolutionary biology and developmental biology, and possibly lay the foundation for future research and discussion on this seminal topic.
