Queen conch (Strombus gigas) ovarian gene expression in the Florida Keys: offshore versus nearshore

ABSTRACT: Reproduction of queen conchs at nearshore sites in the Florida Keys is known to be impaired (Delgado et al. 2004). A recent microarray study of male queen conchs collected from the Florida Keys during the early part of the reproductive season (February, 2007) indicated that NS conchs show differences in expression of spermatogenesis-related and small GTPase signaling transcripts (Spade et al. 2010). The current study investigates gene expression in the ovary of female queen conchs from the same sampling effort in February, 2007.

The current study investigates gene expression in the ovary of female queen conchs from the same sampling effort in February, 2007. One-color (Cy3) oligonucleotide array experiment. Each array sample is an individual biological replicate. The study includes four biological replicates offshore and three biological replicate nearshore. Offshore conchs exhibit normal reproduction, and so were considered the reference group in the analysis.

The current study investigates gene expression in the digestive gland, which is closely associated with ovary, of female queen conchs from the same sampling effort in February, 2007. One-color (Cy3) oligonucleotide array experiment. Each array sample is an individual biological replicate. The study includes four biological replicates offshore and three biological and one technical replicate nearshore. Offshore conchs exhibit normal reproduction, and so were considered the reference group in the analysis.

microRNA and aging

Project description:The critical role of the endothelium in governing vascular, tissues homeostasis and pathological processes is increasingly recognized (Deanfield et al., 2007). Cellular senescence of endothelial cells has been proposed to be involved in endothelial dysfunction and atherogenesis (Minamino T et al., 2007), although the mechanisms underlying the aging induced attenuation of endothelium dependent functions are yet to be clarified. Recent evidences implicated overall miRNA levels and miRNA in regulating angiogenesis and endothelial function (Suarez et al., 2007; Kuehbacher et al., 2007; Harris et al., 2008; Fish et al. 2008; Wang et al., 2008).

Understanding differential heat tolerance of the threatened mountainous star coral Orbicella faveolata from inshore and offshore reef sites in the Florida Keys using gene network analysis

Project description:We subjected three inshore and four offshore genotypes of the coral Orbicella faveolata to 30, 31, 32, or 33ºC for 31 days and measured photochemical efficiency (Fv/Fm), the types and relative abundance of dinoflagellate endosymbionts, and gene expression of the host and symbiont. All inshore coral genotypes, regardless of symbiont type, were significantly more thermotolerant than offshore genotypes based on declines in Fv/Fm. The most heat-tolerant inshore genotype (In1) was dominated by Durusdinium trenchii; all other genotypes were Breviolum-dominated, suggesting local adaptation or acclimatization contributes to the heat tolerance of inshore genotypes. After 31 days of heat stress, all coral genotypes (except In2) had lost most of their Breviolum and became dominated by D. trenchii. Host genotype In1 presented unique expression patterns of genes involved in heat shock response, immunity, and protein degradation. There were few changes in the symbiont transcriptomes of inshore corals under heat stress, but significant changes in symbiont gene expression from the offshore colonies, including increases in ribosomal and photosynthetic proteins. These data show that the differential thermotolerance between inshore and offshore O. faveolata in the Florida Keys is associated with statistically significant differences in both host and symbiont gene expression that provide insights into the mechanisms underlying holobiont heat tolerance.

Understanding differential heat tolerance of the threatened coral Orbicella faveolata from transplanted reef sites in the Florida Keys using gene network analysis

Project description:Twelve inshore and six offshore colonies were reciprocally transplanted during 1 year (July 2017- July 2018) at Florida Keys (location). After this period samples were collected from the field and brought to the Experimental Reef Laboratory facilities (RSMAS, Miami) to be acclimated to 30C during 7 days in six aquaria. Three aquaria were keep under initial conditions for the duration of the experiment (30C) and three aquaria had the temperature increased everyday during 7 days to a final temperature of 32C. A total of 56 samples were collected for RNAseq after 6 days of the temperature treatment and stored at -80C.

grape berry vacuole proteomic - Quantitative Proteome Analysis Reveals Changes in the Protein Landscape During Grape Berry Development With a Focus on Vacuolar Transport Proteins

Project description:The vacuole occupies a large portion of plant cell volume, it is especially true to fruit tissues. Berry flesh cell vacuole serves as storage organelle for water, sugars, acids, secondary metabolites and others, which largely determining berry quality (Fontes et al., 2011a, b; Shiratake and Martinoia, 2007, Conde et al., 2006). However, the molecular basis of these compartmentation processes is still poorly understood. As in many species, the major bottle neck to study these aspects in grapevine is to obtain highly purified vacuoles with a good yield (Fontes et al., 2010). Up to date, several vacuole or tonoplast proteome researches were applied on a few plants mainly on Arabidopsis thaliana, vacuoles or tonoplast were derived from mesophyll cells (Carter et al., 2004, Endler et al., 2006, Schulze, et al., 2012) or cell culture (Jaquinod et al 2006, Shimaoka et al 2004), cauliflower buds (Schmidt et al., 2007) and sugar beet taproots (Jung et al., 2015). Though the grape berry protoplasts and intact vacuoles were successfully isolated from Cabernet Sauvignon berry suspension-cultured cells (Fontes et al., 2010), the vacuoles isolated from grape berry or different development and ripening stages of grape berry mesocarp tissues were not achieved.
