Reef-building corals depend for much of their energy on photosynthesis by symbiotic dinoflagellate algae (genus Symbiodinium) that live within their gastrodermal cells. However, the cellular mechanisms underpinning this ecologically critical symbiosis, including those governing the specificity of symbiont uptake by the host, remain poorly understood, in part because of the difficulties of worki...

Self-incompatibility (SI) in higher plants is an important mechanism to prevent inbreeding and involves specific rejection of incompatible ("self") pollen. In field poppy (Papaver rhoeas), S proteins encoded by the stigma component of the S-locus interact with incompatible pollen, resulting in cessation of tip growth. This "self" interaction triggers a Ca(2+)-dependent signaling network, involv...
