Genotypic diversity, molecular markers and spatial distribution of genets in clonal plants, a literature survey

Abstract: We present a literature survey of studies using molecular markers to investigate genet diversity and structure in clonal plants. The data from 40 studies comprised 45 species of which only two were studied by DNA methods, the rest by isozyme markers. Less than one third of the studies provided information about the spatial distribution of individual genets within populations, and only 12.5% of the studies used mapping of all ramets within plots or part of the population in combination with identification of multilocus genotypes. We also present two case studies. InGlechoma hederacea morphological criteria were used to select clones. Multi-samples of ramets within these “clones” turned out to be variable using isozymes indicating that these “clones” in most cases consisted of several genets. One individual multilocus genotype covered tens of square metres. InHylocomium splendens samples from 10×10 cm plots usually consisted of a mixture of multilocus genotypes, but occasionally the whole plot consisted of one genet.

Telerobotic response requirements

Abstract: The bandwidth and response characteristics required for effective telerobotic control are investigated. The definition of these requirements is based on surveying existing literature on teleoperation, robotics, and human factors to determine if sufficient knowledge in this area is available to adequately specify appropriate requirements. An idealized design goal based on the concept of telepresence is presented. To further clarify the response requirements, the control problem is divided into the two major components of teleoperation: the human operator and the telerobot. The literature survey showed that humans have asymmetrical input/output capabilities. It was also found that a human does not have one single relevant bandwidth, but rather that bandwidth is a function of the human's mode of operation. A survey was conducted in which 12 experts were queried to find a consensus based on experience. These results are presented and recommendations are derived. >

EcoGene: a genome sequence database for Escherichia coli K-12

Abstract: The EcoGene database provides a set of gene and protein sequences derived from the genome sequence of Escherichia coli K-12. EcoGene is a source of re-annotated sequences for the SWISS-PROT and Colibri databases. EcoGene is used for genetic and physical map compilations in collaboration with the Coli Genetic Stock Center. The EcoGene12 release includes 4293 genes. EcoGene12 differs from the GenBank annotation of the complete genome sequence in several ways, including (i) the revision of 706 predicted or confirmed gene start sites, (ii) the correction or hypothetical reconstruction of 61 frame-shifts caused by either sequence error or mutation, (iii) the reconstruction of 14 protein sequences interrupted by the insertion of IS elements, and (iv) pre-dictions that 92 genes are partially deleted gene fragments. A literature survey identified 717 proteins whose N-terminal amino acids have been verified by sequencing. 12 446 cross-references to 6835 literature citations and abstracts are provided. EcoGene is accessible at a new website: http://bmb.med.miami. edu/EcoGene/EcoWeb . Users can search and retrieve individual EcoGene GenePages or they can download large datasets for incorporation into database management systems, facilitating various genome-scale computational and functional analyses.
