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)
Recent methodological developments in plant phenotyping, as well as the growing importance of its applications in plant science and breeding, are resulting in a fast accumulation of multidimensional data. There is great potential for expediting both discovery and application if these data are made publicly available for analysis. However, collection and(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)
Plasma fibronectin (Fn) induces phagocytosis of C3b-opsonized sheep erythrocytes (EC3b) by human peripheral blood monocytes. However, Fn does not induce erythrophagocytosis of EC3b by human polymorphonuclear leukocytes (PMN), unless the PMN have been exposed to C5a or N-formyl-methionyl-leucyl-phenylalanine. Because of this difference, it is of great(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)
A major problem in the cryopreservation of human polymorphonuclear leukocytes (PMN) is the loss of phagocytic function in cryopreserved cells. This is not a problem with cryopreserved monocytes. To study the reasons for this difference in detail, PMN and monocytes were either osmotically stressed in hypertonic media or were frozen to various temperatures.(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)
