Brown algae (Phaeophyceae) are complex photosynthetic organisms with a very different evolutionary history to green plants, to which they are only distantly related. These seaweeds are the dominant species in rocky coastal ecosystems and they exhibit many interesting adaptations to these, often harsh, environments. Brown algae are also one of only a small(More)
We have investigated the effect of plasma fibronectin (Fn) on binding and phagocytosis of sheep erythrocytes (E) by human peripheral blood monocytes. Unopsonized E were not phagocytosed in the absence or presence of Fn, but Fn enhanced the phagocytosis of E bearing IgG. Sheep erythrocytes sensitized with IgM and C3b were ingested only when monocytes were(More)
Genomic projects heavily depend on genome annotations and are limited by the current deficiencies in the published predictions of gene structure and function. It follows that, improved annotation will allow better data mining of genomes, and more secure planning and design of experiments. The purpose of the GeneFarm project is to obtain homogeneous,(More)
We have investigated the interactions between plasma fibronectin (Fn) and human peripheral blood phagocytic cells. As shown by studies of the binding of Fn-coated fluorescent microspheres (Fn-ms), both polymorphonuclear leukocytes (PMN) and monocytes had specific binding sites for Fn at the plasma membrane. However, as purified from blood, only monocytes(More)
Data integration is a key challenge for modern bioinformatics. It aims to provide biologists with tools to explore relevant data produced by different studies. Large-scale international projects can generate lots of heterogeneous and unrelated data. The challenge is to integrate this information with other publicly available data. Nucleotide sequencing(More)
Plant phenotypic data shrouds a wealth of information which, when accurately analysed and linked to other data types, brings to light the knowledge about the mechanisms of life. As phenotyping is a field of research comprising manifold, diverse and time-consuming experiments, the findings can be fostered by reusing and combining existing datasets. Their(More)
— Many vocabularies and ontologies are produced to represent and annotate agronomic data. By reusing the NCBO BioPortal technology, we have already designed and implemented an advanced prototype ontology repository for the agronomy domain. We plan to turn that prototype into a real service to the community. The AgroPortal project aims at reusing the(More)
The advancements in empirical technologies has generated vast amounts of heterogeneous data. This situation has created a need to integrate the data to understand the system of interest in its entirety. Therefore, information systems play a crucial role in managing these data, enabling the biologists in the extraction of new knowledge. The plant(More)

Gene detection and structural annotations of plant model genomes is mainly done by bioinformatics groups running large sequences databases (essentially MIPS and TIGR). The raw material is the assembled genome sequences produced by standardized methods. Functional annotation is a more comple x process based on bioinformatic approaches, many heterogeneous(More)
