Who came first: NK or HOX??? insights from Homeobox genes of Sponges

By | May 7, 2021

In this blog post we take a look into homeobox repertoire of “Sponges-The pore bearers”. Homeobox genes in most primitive organism on earth “Ctenophores”  gave some valuable insights and now we go a bit ahead in tree of life to gain further insights from demosponge Amphimedon queenslandica genome sequence. The first conclusive evidence for presence of… Read More »
