The structure of the Z pseudo-organ in Xiphinema diversicaudatum consists of a muscular mass of about 80 cells arranged in rings of four cells each. These cells have peripheral nuclei and are connected with a glandular monolayered epithelium, which lines the lumen of the Z pseudo-organ. Globular bodies originate from the membranes of the epithelial tissue. They consist of a series of closed vesicles con- taining secretions, and of tubules through which the secretions flow into the lumen. The globular bodies have a helicoidal distribution within the lumen of the Z pseudo-organ which presumably slows the passage of the egg. Enzymatic digestion, in viva, indicates that the secretion consists of acid and basic proteins involved in egg shell formation.

Abstract
The structure of the Z pseudo-organ in Xiphinema diversicaudatum consists of a muscular mass of about 80 cells arranged in rings of four cells each. These cells have peripheral nuclei and are connected with a glandular monolayered epithelium, which lines the lumen of the Z pseudo-organ. Globular bodies originate from the membranes of the epithelial tissue. They consist of a series of closed vesicles con- taining secretions, and of tubules through which the secretions flow into the lumen. The globular bodies have a helicoidal distribution within the lumen of the Z pseudo-organ which presumably slows the passage of the egg. Enzymatic digestion, in viva, indicates that the secretion consists of acid and basic proteins involved in egg shell formation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
