“…On the other hand, the stolon tip is also source of a signal molecule termed stolon-inducing factor (SIF: Lange et al, 1989, Lange andMüller, 1991). When growing to proximity to the flank of another stolon, secreted SIF induces the formation of a second, laterally growing tip (Fig.…”

“…These occur exclusively in the stolon compartment and are not used to catch prey. Upon histoincompatible contacts their differentiation from pluripotent stem cells is induced thus increasing their frequency from normally one per mm stolon length up to 400 per mm in the so-called hyperplastic stolons of incompatible colonies (Lange et al, 1989). In the course of tissue rejection combat, microbasic mastigophores are recruited from distant areas, migrate quickly to and accumulate at contact sites (Fig.…”

“…Here, the stinging cells turn around, directing their sensory cnidocil to the encountered neighbor, and synchronously discharge their toxins into its tissue. Mutual attacks are repeated until only one competitor survives (Lange et al, 1989(Lange et al, , 1992movie: Müller, 1996). A member of the COUP family of transcription factors is expressed in the contact area .…”

“…True tissue fusions between allogeneic adult colonies are not common in the Cnidaria, although they have been documented in the Hydrozoa (Hauenschild, 1954(Hauenschild, , 1956Buss et al, 1985;Shenk, 1991;Frank and Rinkevich, 1994). Most histocompatibility related studies in the Cnidaria (reviewed by Leddy and Green, 1991) have been carried out on scleractinian corals (Potts, 1976;Hildemann et al, 1977;Criens, 1982 Rinkevich andLang and Chornesky, 1990;Chadwick-Furman and Rinkevich, 1994;Rinkevich et al, 1994), hydrozoans (Hauenschild, 1954(Hauenschild, , 1956Ivker, 1972;Miiller et al, 1983;Buss et al, 1984Buss et al, , 1985Bosch and David, 1986;Lange et al, 1989;Frank and Rinkevich, 1994) and gorgonians (Theodor, 1970;Theodor and Senelar, 1975;Theodor, 1976;Bigger and Runyan, 1979;Lasker and Coffroth, 1985;Salter-Cid and Bigger, 1991).

AbstractAllogeneic encounters were experimentally arranged in Eilat, Red Sea for the first time in the Alcyonacea with the soft coral Pareryfkpodium ft.&urn fulvum. All possible pairwise combination assays within two groups of five colonies each and one group of three colonies were setup in situ in 2-4 replicates each (a total of 76 assays). Control isogeneic encounters always resulted in complete tissue fusion. Two types of allogeneic responses were documented following tissue-totissue contacts. The first was retreat growth, in which contacting allografts started to retreat from each other a few days following direct contact until a bare area of a few mm separated them. In several assays the colonies repeatedly grew into contact and retreated again. The second allogeneic response was unilateral or reciprocal tissue overgrowth. In this type of response one colony overgrew the conspecific partner by several mm and then stopped. The underlying tissue of the overgrown partner died. No cytotoxicity was observed in allogeneic contacts either in growing parts or when assays were established between cut surface areas. Repeated assays of the same pair-combination were not consistent in terms of type and directionality of responses. We propose that effector mechanisms elicited following allogeneic encounters in P. J fulvum may be affected by biological as well as non-biological parameters and are not specific to the type of allogeneic challenge. However, colony specificity in this species is restricted only to the level of self-and non-self discrimination.

Abstract. Allogeneic assays were conducted in situ on the Red Sea hydrocoral Millepora dichotoma. Forty-five pairwise combinations among ten colonies and ten control isografts were set up in four replicates each (I 80 and 40 pairs, respectively) and followed for up to 8 mo in the Gulf of Eilat, Red Sea in 1992-1993. In 42 allogeneic combinations we recorded a reproducible and unilateral tissue and skeleton overgrowth which developed within the first 10 wk up to 20 mm. Following the development of these primary overgrowths, four types of secondary responses were observed among most incompatible combinations: reversals in overgrowth directionality, tissue necroses, stand-offs and abnormal growth patterns. Secondary responses within a given set of replicates of most allogeneic combinations were characterized by high variability in type and intensity of response. Based on the outcomes of primary overgrowths, a complex nontransitive hierarchy was constructed for the ten colonies. All isografts and three allogeneic combinations fused within 3 wk. Fusion pattern between the three allogeneic combinations was nontransitive: one M. dichotoma colony repeatedly fused with two other colonies (four assays each). However, these two colonies not only did not fuse with each other, but one of them repeatedly overgrew its confr6re. In the third compatible combination, the most superior and the most inferior colonies in the network of hierarchies among the ten colonies, fused in all tested assays. These results are compared with allogeneic outcomes in other cnidarians, where nontransitive fusion between allogeneic colonies have never been recorded.

Histoincompatibility in a low invertebrate, Hydractinia echinata: Analysis of the mechanism of rejection

Abstract: The colonial hydroid Hydructiniu echinata is able to discriminate between self and non-self. Encounters between isogeneic, or allogeneic but histocompatible, colonies of this hydroid result in fusion, whereas incompatible colonies do not fuse but display a peculiar mode of rejection.
