报告摘要：

Lophotrochozoans, embracing such taxa as brachiopods and molluscs, represent one of the three major groups of bilaterians. They have pivotal roles in understanding the origins and evolution of animal body plans because, after Ediacaran, they left an abundant and continuous fossil record of the shells, which consitute integral parts of their body plans. To gain insight into the origins and evolution of those skeletons (shells), it would be essential to unveil the genetic and molecular mechanisms of their formation processes, which may be decomposed into the following three mutually interwined sub-processes: (1) differentiation along a gene cascade, (2) morphogenesis, and (3) biomineralization. Lophotrochozoan shell formation is still enigmatic in each of those sub-processes. In my talk, I shall focus on some remaining problems in (1) and (3), and provide with some possible solutions to them.
