Project description:Publication Abstract: As climate changes, sea surface temperature anomalies that negatively impact coral reef organisms continue to increase in frequency and intensity. Yet, despite widespread coral mortality, genetic diversity remains high even in those coral species listed as threatened. While this is good news in many ways it presents a challenge for the development of biomarkers that can identify resilient or vulnerable genotypes. Taking advantage of three coral restoration nurseries in Florida that serve as long-term common garden experiments, we exposed over thirty genetically distinct Acropora cervicornis colonies to hot and cold temperature shocks seasonally and measured pooled gene expression responses using RNAseq. Targeting a subset of twenty genes, we designed a high-throughput qPCR array to quantify expression in all individuals separately under each treatment with the goal of identifying predictive and/or diagnostic thermal stress biomarkers. We observed extensive transcriptional variation in the population, suggesting abundant raw material is available for adaptation via natural selection. However, this high variation made it difficult to correlate gene expression changes with colony performance metrics such as growth, mortality, and bleaching susceptibility. Nevertheless, we identified several promising diagnostic biomarkers for acute thermal stress that may improve coral restoration and climate change mitigation efforts in the future.

Project description:Epigenetic modifications directly regulate the patterns of gene expression by altering DNA accessibility and chromatin structure. A knowledge gap is presented by the need to directly measure these modifications, especially for unannotated organisms with unknown primary histone sequences. In the present work, we developed and applied a novel workflow for identifying and annotating histone proteoforms directly from mass spectrometry-based measurements for the endangered Caribbean coral Acropora cervicornis. Combining high accuracy de novo top-down and bottom-up analysis based on tandem liquid chromatography, trapped ion mobility spectrometry, non-ergodic electron-based fragmentation, and high-resolution mass spectrometry, near complete primary sequence (up to 99%) and over 86 post-translational modification annotations were obtained from pull-down histone fractions. In the absence of reliable genome annotations, H2A, H2B and H4 histone sequences and the annotation of the post-translational modifications of the stressed A. cervicornis coral allow for a better understanding of chromatin remodeling and new strategies for target intervention and restoration of endangered reef corals.
