Project description:The European clam, Ruditapes decussatus (Linnaeus, 1758) is a bivalve mollusc of the family Veneridae native to the European Atlantic and Mediterranean coastal waters. Its production is exclusively based on natural recruitment, which is subject to high annual fluctuations due to adversely affected by pollution and other environmental factors. Microarray analyses have been performed in four gonadal maturation stages of two higly productive Portuguese wild populations (Ria Formosa in South and Ria de Aveiro in North) characterized by different responses to spawning induction.

Project description:A short-term microcosm experiment was conducted to evaluate the impact of wastewater discharge on coastal microbial communities. Coastal seawater was exposed to two types of treated wastewater: (i) unfiltered wastewater, containing nutrients, pollutants, and allochthonous microbes, and (ii) filtered wastewater, which retained only nutrients and pollutants while removing microbial components. Metaproteomic samples were collected from the coastal seawater prior to the experiment and from each experimental flask at the late exponential growth phase to assess microbial functional responses to wastewater exposure.

Project description:<p>Copy number variation (CNV) has been recognized as a major contributor to human genome diversity. It plays an important role in determining phenotypes and has been associated with a number of common and complex diseases. However the CNV data from diverse populations is rather limited. Here we report the first investigation of copy number variation (CNV) in the indigenous populations from Peninsular Malaysia. We genotyped 34 Negrito genomes from Peninsular Malaysia using the Affymetrix SNP 6.0 microarray and identified 62 putative novel CNVs, consisting of 25 gains and 37 losses. These CNVs appear unique to the Negrito population and were absent in the DGV, HapMap3 and Singapore Genome Variation Project (SGVP) datasets. Analysis of gene ontology revealed that genes within these CNVs were enriched in the immune system (GO:0002376), response to stimulus mechanisms (GO:0050896), as well as the metabolic pathways (GO:0001852). Copy number gains in CNVRs enriched with genes were significantly higher than the losses (P value <0.001). Therefore, in view of the small population size, relative isolation and semi-normadic lifestyles of this community, we speculate that these CNVs may be attributed to recent local adaptation of Negritos from Peninsular Malaysia.</p>

Project description:purpose:The large-scale reproduction of Phaeocystis globosa has caused serious damage to the marine ecosystem in the coastal waters of China. The outbreak of algae blooms depends on the competitive advantage of their heteromorphic life history: colonial formation is beneficial to resist zooplankton predation, and the single isolated cells can absorb nutrients rapidly. methods:For RNA exaction, the biomass was resuspended in 2 mL RNA extraction buffer (1:1 mix of aqua-phenol and buffer L [0.5% SDS, 10 mM EDTA, 0.2 M sodium acetate (pH 5), and 1:100 β-mercaptoethanol)] and then incubated with DNase I (Takara, Japan) for 30 min at 37 °C to remove genomic DNA. RNA quality analysis, library construction, sequencing, data filtering and mapping were performed by the Novogene Bioinformatics Technology Co., Ltd. (Beijing, China). results:Three biological replicates from GX-C and ST-C were ensured statistical comparability and reliability of data. Raw data ranged from 25, 608,632 to 35,516,726 reads per sample. After producing more than 24 million clean reads, removing low-quality sequences and adapter sequences. Additionally, 4386 genes were differentially expressed at statistically significant levels, which included 2268 up-regulated genes and 2118 down-regulated genes. Genes with significant differential expression were involved in several pathways, including starch and sucrose, phagosome, inositol phosphate metabolism, fatty acid degradation. conclusions: In summary, we can find that colonial cells have stronger carbon fixation capacity. It is not used to synthesize fatty acids as reserves of energy, but to secrete EPS. The reduction of fatty acid makes P. globosa become “low-quality food” and the formation of colony from EPS reduces the chance of being ingestion by zooplankton.

Project description:The European clam, Ruditapes decussatus (Linnaeus, 1758) is a bivalve mollusc of the family Veneridae native to the European Atlantic and Mediterranean coastal waters. Its production is exclusively based on natural recruitment, which is subject to high annual fluctuations due to adversely affected by pollution and other environmental factors. A microarray-based analysis was performed with the objectives of describe genomic feature of oocytes and identify potential markers of oocyte quality in the economically important European clam, Ruditapes decussatus. The oocytes of a total of 25 females from Ria de Aveiro, Western coast of Portugal, were selected for this study and their quality was estimated by early developmental success until D-larval rate, under controlled conditions.
