Summary The developmental sequence of events surrounding wound healing in the coenocytic marine green algaCaulerpa ashmeadii was investigated. The wound plug was found to consist primarily of polysaccharide, including sulfated forms. Low levels of protein found in the wound plug were interpreted to occur from cytoplasmic leakage during the initial wounding response. An initial retraction of the vegetative cytoplasm from the wound site occurred upon wounding. A cytoplasmic band extended across the vacuole away from the wound plug 1 hour after wounding and migrated to a position adjacent to the wound plug by 2 hours. Cytological changes from 30 minutes to 6 hours resulted in a wound cytoplasm that was similar in appearance to meristematically active areas. New wall formation began at 2 hours following wounding and was complete by 48 hours after wounding.
