We have sequenced and annotated the genome of ®ssion yeast (Schizosaccharomyces pombe), which contains the smallest number of protein-coding genes yet recorded for a eukaryote: 4,824. The centromeres are between 35 and 110 kilobases (kb) and contain related repeats including a highly conserved 1.8-kb element. Regions upstream of genes are longer than in budding yeast (Saccharomyces cerevisiae), possibly re¯ecting more-extended control regions. Some 43% of the genes contain introns, of which there are 4,730. Fifty genes have signi®cant similarity with human disease genes; half of these are cancer related. We identify highly conserved genes important for eukaryotic cell organization including those required for the cytoskeleton, compartmentation, cell-cycle control, proteolysis, protein phosphorylation and RNA splicing. These genes may have originated with the appearance of eukaryotic life. Few similarly conserved genes that are important for multicellular organization were identi®ed, suggesting that the transition from prokaryotes to eukaryotes required more new genes than did the transition from unicellular to multicellular organization.We report here the completion of the fully annotated genome sequence of the simple eukaryote Schizosaccharomyces pombe, a ®ssion yeast. It becomes the sixth eukaryotic genome to be sequenced, following Saccharomyces cerevisiae 1 , Caenorhabditis elegans 2 , Drosophila melanogaster 3 , Arabidopsis thaliana 4 and Homo sapiens 5,6 . The entire sequence of the unique regions of the three chromosomes is complete, with gaps in the centromeric regions of about 40 kb, and about 260 kb in the telomeric regions. The completion of this sequence, the availability of sophisticated research methodologies, and the expanding community working on S. pombe, will accelerate the use of S. pombe for functional and comparative studies of eukaryotic cell processes.

This study involved a population of young Mexican students (N ϭ 526, ages nine to seventeen). It used U.S. instruments to evaluate these students' attitudes about conflict, communication skills, conflict styles, and conflict management message styles in a Hispanic school environment in order to explore the degree of applicability of these instruments to young Spanish-speaking students and to analyze the relations between these constructs. A model in which attitudes about conflict and communication skills predict the conflict management messages was shown to be significant after the corresponding structural analysis.T he relation between attitudes and behavior has been debated for decades (Reardon, 1989;Laca, 2005). Present-day studies indicate that attitudes influence behavior and can predict it to some degree, even though this influence is not simple and is affected by various moderators. "There are many of these moderators, the majority of which seem to be related to aspects of the situation, aspects of the attitudes themselves and aspects of the individual" (Baron and Byrne, 2002, p. 13). Applying to conflict the definition of attitude stated by Rubin, Pruitt, and Kim (1994, p. 252)-"a positive or negative feeling toward a person or object"-our view coincides with that of Mayer (2000) in that this positive or negative feeling, the way in which the conflict is seen, will largely determine how it is dealt with. By being aware of the positive or negative feelings of young people, and their attitudes toward conflict, we have a first indication of their behavior in real situations of conflict. From this perspective, we

A xylanolytic and phosphate-solubilizing bacterium isolated from sawdust of Ulmus nigra in Salamanca was characterized by a polyphasic approach. The novel strain, designated XIL02(T), was Gram-positive, aerobic, catalase- and oxidase-negative, rod-shaped and non-motile. Phylogenetically and chemotaxonomically, it was related to members of the genus Microbacterium. According to 16S rRNA gene sequence analysis, it is closely related to Microbacterium arborescens and Microbacterium imperiale; however, DNA-DNA hybridization showed reassociation values less than 70 % with the type strains of these species. In chemotaxonomic analyses, the major menaquinones detected were MK-12, MK-13 and MK-11 and the major fatty acids were anteiso-C(15 : 0), anteiso-C(17 : 0) and iso-C(16 : 0); the peptidoglycan was of the type B2beta. The G+C content determined was 69 mol%. Based on the present data, it is proposed that strain XIL02(T) (=LMG 20991(T)=CECT 5976(T)) be classified as the type strain of a novel Microbacterium species, for which the name Microbacterium ulmi sp. nov. is proposed.
