The following histochemical tests were performed: Sudan IV for lipids; 10% aqueous ferric chloride to locate phenolic compounds; and Ruthenium red solution to detect pectic compounds (Johansen 1940).
All cells of the colleter body reacted positively to Ruthenium red indicating the presence of pectic compounds in the cytosol and intercellular spaces.
These were control, ionomycin, ruthenium red and thapsigargin.
Treatment with ruthenium red had no impact on spawning, and fragments of each coral that spawned under control conditions also spawned in ruthenium red at around the same time (Table 1).
All samples treated with ruthenium red spawned within 5 min of control clonal fragments, emphasizing the major difference brought about by exposure to ionomycin or thapsigargin, which in most cases blocked spawning completely or, in one example, delayed it by an hour.
Motility and calcium mobilization induced by SIN-1 in Arbacia punctulata sperm were also found to be inhibited by ruthenium red (Fig.
