Project description:Florida’s coral reefs are currently experiencing a multi-year disease-related mortality event, that has resulted in massive die-offs in multiple coral species. Coral monitoring data and disease prevention/treatment efforts from recent years have identified individual Orbicella faveolata that possess high, moderate, or low resistance to stony coral tissue loss disease (SCTLD). Ninety samples of high, moderate, or low SCTLD resistance were collected from 3 reefs for bottom-up LC-MS/MS analysis (n=30 for each resistance category).
Project description:We previously identified that the RNA binding protein Nucleolin is localized to axons of DRG sensory neurons by interaction with the molecular motor Kinesin-1 (Kif5A) and subsequently localizes importin beta1 mRNA there (Perry et al., 2016). To further identify additional RNAs that are localized to axons in a similar mechanism, we immunopercipitated Kif5A from dorsal roots (centrally projecting axons) or Sciatic nerves (peripherally projecting axons), isolated the bound RNA and sequnced it.
Project description:Summer mortality of the Pacific oyster Crassostrea gigas is the result of a complex interaction between oysters, their environment and pathogens. Heredity appears to be a major factor determining the sensitivity of oysters to summer mortality, allowing resistant (R) and susceptible (S) lines to be produced. We conducted genome-wide expression profiling of R and S gonads during the 3-month period preceding a summer mortality event using a 9K cDNA microarray that we designed. This transcriptional analysis provides new indications to define markers for Quantitative Trait Loci searches and functional studies, and evaluates the potential role of each gene in the resistance to summer mortality
