Abstract : Respiratory toxicity, injury and treatment following vapor inhalational exposure to the chemical warfare nerve agent (CWNA) soman (GD) were examined in non-anesthetized rats. This study exposed male Sprague-Dawley rats (250-300g) to 520, 560, 600, 825 or 1410mgxmin/m(3) of soman in a customized head-out inhalation system. Signs of CWNA-induced cholinergic crises were observed in all soman-exposed animals. The LCt50 of vaporized soman as determined by probit analysis was 593.1mgxmin/m(3). All animals exposed to 825 and 1410mgxmin/m(3) developed severe convulsions and died within 4-8min post-exposure. Edema measured by wet/dry weight ratio of the left lung lobe increased in a dose-dependent manner in all soman-exposed animals. Bronchoalveolar lavage (BAL) fluid and blood acetylcholinesterase (AChE) activities were inhibited dose-dependently in soman-exposed groups at 24h. A significant increase in total BAL protein was observed in soman-exposed animals at all doses. AChE activity was inhibited in lung and whole brain tissues in all soman-exposed animals. Histopathological analysis of the lungs of animals exposed to 600mgxmin/m(3) of soman revealed prominent morphological changes including alveolar histiocytosis, hemorrhage and inflammation consisting of neutrophilic exudate. Exposure of animals to 600mgxmin/m(3) of soman followed by treatment with two actuations for 10s of Combivent (21mug of ipratropium bromide and 120mug of albuterol sulfate) and Symbicort (80mug budesonide and 4.5mug formoterol) by inhalation into a modified metered dose inhaler (MDI) 10min post-exposure resulted in increased minute volume, but did not decrease mortality. These results indicate that inhalation exposure to soman vapor causes acute respiratory toxicity and injury in untreated, un-anesthetized rats and that inhalation treatment with Combivent or Symbicort did improve the respiratory outcomes, but did not influence lethality.

Abstract : The nucleotide sequence was determined for a 340-kb segment of rice chromosome 2, revealing 56 putative protein-coding genes. This represents a density of one gene per 6.1 kb, which is higher than was reported for a previously sequenced segment of the rice genome. Sixteen of the putative genes were supported by matches to ESTs. The predicted products of 29 of the putative genes showed similarity to known proteins, and a further 17 genes showed similarity only to predicted or hypothetical proteins identified in genome sequence data. The region contains a few transposable elements: one retrotransposon, and one transposon. The segment of the rice genome studied had previously been identified as representing a part of rice chromosome 2 that may be homologous to a segment of Arabidopsis chromosome 4. We confirmed the conservation of gene content and order between the two genome segments. In addition, we identified a further four segments of the Arabidopsis genome that contain conserved gene content and order. In total, 22 of the 56 genes identified in the rice genome segment were represented in this set of Arabidopsis genome segments, with at least five genes present, in conserved order, in each segment. These data are consistent with the hypothesis that the Arabidopsis genome has undergone multiple duplication events. Our results demonstrate that conservation of the genome microstructure can be identified even between monocot and dicot species. However, the frequent occurrence of duplication, and subsequent microstructure divergence, within plant genomes may necessitate the integration of subsets of genes present in multiple redundant segments to deduce evolutionary relationships and identify orthologous genes.

Abstract : The genome of the model plant Arabidopsis thaliana has been sequenced by an international collaboration, The Arabidopsis Genome Initiative. Here we report the complete sequence of chromosome 5. This chromosome is 26 megabases long; it is the second largest Arabidopsis chromosome and represents 21% of the sequenced regions of the genome. The sequence of chromosomes 2 and 4 have been reported previously and that of chromosomes 1 and 3, together with an analysis of the complete genome sequence, are reported in this issue. Analysis of the sequence of chromosome 5 yields further insights into centromere structure and the sequence determinants of heterochromatin condensation. The 5,874 genes encoded on chromosome 5 reveal several new functions in plants, and the patterns of gene organization provide insights into the mechanisms and extent of genome evolution in plants.

Abstract : The higher plant Arabidopsis thaliana (Arabidopsis) is an important model for identifying plant genes and determining their function. To assist biological investigations and to define chromosome structure, a coordinated effort to sequence the Arabidopsis genome was initiated in late 1996. Here we report one of the first milestones of this project, the sequence of chromosome 4. Analysis of 17.38 megabases of unique sequence, representing about 17% of the genome, reveals 3,744 protein coding genes, 81 transfer RNAs and numerous repeat elements. Heterochromatic regions surrounding the putative centromere, which has not yet been completely sequenced, are characterized by an increased frequency of a variety of repeats, new repeats, reduced recombination, lowered gene density and lowered gene expression. Roughly 60% of the predicted protein-coding genes have been functionally characterized on the basis of their homology to known genes. Many genes encode predicted proteins that are homologous to human and Caenorhabditis elegans proteins.

Abstract : The plant Arabidopsis thaliana (Arabidopsis) has become an important model species for the study of many aspects of plant biology. The relatively small size of the nuclear genome and the availability of extensive physical maps of the five chromosomes provide a feasible basis for initiating sequencing of the five chromosomes. The YAC (yeast artificial chromosome)-based physical map of chromosome 4 was used to construct a sequence-ready map of cosmid and BAC (bacterial artificial chromosome) clones covering a 1.9-megabase (Mb) contiguous region, and the sequence of this region is reported here. Analysis of the sequence revealed an average gene density of one gene every 4.8 kilobases (kb), and 54% of the predicted genes had significant similarity to known genes. Other interesting features were found, such as the sequence of a disease-resistance gene locus, the distribution of retroelements, the frequent occurrence of clustered gene families, and the sequence of several classes of genes not previously encountered in plants.
