Polychasial cyme (multiparous)

multiple branches arise at the base of the apical flower on the peduncle. The oldest flower is placed in the middle of the axis

#XL - T Zoology

Notum, a hydrolase that associates with glypican and then cleaves off Wnt’s attached lipids in a process of deacylation or delipidation.

Delipidation process reduces Wnt signaling, creates a negative feedback mechanism for preventing excessive Wnt signaling.
