摘要：

The ultrastructure of adhesion complexes between gametic flagellar membranes of Chlamydomonas reinhardtii Dangeard was analyzed using the quick-freeze deep-etch technique. The sexual agglutinin fibrils interact by forming hybrid fibers that frequently branch, forming extensively cross-bridged meshworks. This pattern of interaction mimics a prominent mode of cell wall formation in Chlamydomonas, supporting the notion that the agglutinins evolved from cell wall proteins and that sexual adhesion and cell wall assembly are homologous events.
