Plant expansins in bacteria and fungi: evolution by horizontal gene transfer and independent domain fusion.

abstract：:Partial 18S rRNA sequence of the nemertine Cerebratulus lacteus was obtained and compared with those of coelomate metazoans and acoelomate platyhelminths to test whether nemertines share a most recent common ancestor with the platyhelminths, as traditionally has been implied, or whether nemertines lie within a protost...
