Project description:Over the past several decades, corals worldwide have been affected by global warming, experiencing severe bleaching events that have often lead to coral death. The symbiotic Red Sea coral Stylophora pistillata is considered an opportunistic ‘r’ strategist, thriving in relatively unstable and unpredictable environments, and it is considered a stress-tolerant species. This study aimed to examine S. pistillata gene expression and to clarify the cellular pathways that are active during short-term heat stress caused by an increase from 24°C to 34°C over a 10-day period. Total RNA was extracted from heat-stressed coral fragments, labeled and hybridized against a designated S. pistillata custom microarray containing approximately 12,000 genes. Our results show that the heat stress reaction was sighted from 32°C and intensified significantly after 34°C treatment. Protein interaction networks of up- and down-regulated genes were constructed. The main clustering groups of up-regulated genes were ER stress and ER protein folding, cell cycle, ubiquitin-mediated proteolysis, cell death and cell death regulation and cellular stress response genes. These genes were enriched in cellular pathways related to the unfolded protein response (UPR) in the ER, ER-associated degradation (ERAD) and ubiquitin-mediated proteolysis. An analysis of the down-regulated genes yielded different clusters of genes related to extracellular matrix and actin organization, collagen, negative regulation of cell death and the Notch and Wnt signaling pathways. Genes encoding redox regulation proteins and molecular chaperones may be considered accurate “early warning genes”, while genes related to sensing and repairing DNA damage are severe heat-related genes. Here, we suggest that during short-term heat stress, S. pistillata might divert cellular energy into mechanisms such as UPR and ERAD at the expense of growth and biomineralization processes in an effort to recover from the stress.

Project description:Increasing seawater’s calcium concentration has shown to increase reef building (scleractinian) coral’s calcification rates. In this way the expression of the genes that are associated with the calcification process also altered and, thus can be identified. Needless to say that the overall gene repertoire that participate in the coral calcification process and its molecular mechanisms have not yet been revealed, although sporadic genes that are related to the process have been discovered and investigated. In this study, nubbins of the Red Sea scleractinian coral, Stylophora pistillata were treated with increased calcium concentrations seawater (addition of 100 gm/L) and the genes that have been up-regulated were compared to the genes expression profile of corals with natural seawater calcium concentration. Measurements of AT were taken at mid-day (11:00) and in nighttime (23:00), to record the calcification rates of coral individuals under normal and increased calcium seawater concentrations. In order to reveal the gene involved in the calcification process, S. pistillata fragments of normal and of increased calcium concentrations were sampled for microarray RNA transcriptional profiling at two time-points (mid-day and nighttime).Results of this study have revealed that Smad genes may play a role in the coral skeletal growth apparatus. This study show that the calcification molecular mechanism is conserved Among identified genes are large group of genes that are characterized in the TGF-b/BMP signal transduction pathways which have been revealed in other organisms to participate in bone and cartilage tissue development molecular processes.
