From: Coral bleaching under thermal stress: putative involvement of host/symbiont recognition mechanisms
PdC-Lectin and Pdcyst-rich are expressed by the host. Presence of PdC-Lectin and Pdcyst-rich genes and the zooxanthellae small ribosomal subunit RNA (Zx ssRNA) corresponding gene are investigated by PCR using specific primers on DNA extracted from holobionts (corals plus zooxanthellae, lane 1) or zooxanthellae isolated from S. pistillata and G. fascicularis (lanes 2 and 3, respectively).
