Plant-specific hybrid proline- or glycine-rich proteins (HyP/GRPs) are involved in diverse gene functions including plant development and responses to biotic and abiotic stresses. The quantitative trait locus, qLTG3-1, enhances seed germination in rice under low-temperature conditions and encodes a member with a glycine-rich motif of the HyP/GRP family. The function of this gene may be related ...

The paper introduces the reader to a new paradigm shift that is currently taking place in the data storage industry: the movement toward Clustered Storage architectures. Clustered Storage architectures are changing the rules of how data is stored and accessed. This paper discusses the trends that clearly define clustered storage architectures as the future of data storage, detail the requiremen...

Family clustering of varying levels of serum PBB and DDE was evaluated for 62 Michigan families by using the mean and standard deviation for family units, ranked percentile comparison of family members, and correlation by linear regression of family members. The results indicate that levels of serum PBBs cluster within family units and for children within families. Serum DDE clustering within f...

The bitunicate ascomycete genus Johansonia is presently treated as a member of Saccardiaceae, a family regarded as incertae sedis within the Ascomycota. Recent collections on leaves of a leguminous host, Dimorphandramollis, in Mato Grosso, Brazil, led to the discovery of a new species of Johansonia, described here as J.chapadiensis. Based on DNA sequence data of the nuclear ribosomal DNA (LSU),...

We address the problem of constructing phylogenetic networks using two criteria: the number of cycles and the fit value of the network. Traditionally the fit value is the main objective for evaluating phylogenetic networks. However, a small number of cycles in a network is desired and pointed out in several publications. We propose a new phylogenetic network called CS-network and a method for c...

The human genome is estimated to contain 700 zinc-finger genes, which perform many key functions, including regulating transcription. The dramatic increase in the number of these genes as we move from yeast to C. elegans to Drosophila and to humans, as well as the clustered organization of these genes in humans, suggests that gene duplication has played an important role in expanding this famil...

Polymerase chain reaction (PCR) products were characterized for a repeated sequence family (designated "O-150") of the human filarial parasite Onchocerca volvulus. In phylogenetic inferences, the O-150 sequences clustered into closely related groups, suggesting that concerted evolution maintains sequence homology in this family. Using a novel mathematical model based on a nested application of ...

the radiobiological effects of high atomic number and energy (hze particles) ion beams are of interest for radioprotection in space and tumor radiotherapy. space radiation mainly consists of heavy charged particles from protons to iron ions, which is distinct from common terrestrial forms of radiation. hze particles pose a significant cancer risk to astronauts on prolonged space missions. with ...

We have previously cloned a gene for a developmentally regulated transport protein from the trypanosomatid protozoan Leishmania enriettii. We demonstrate here that this transporter is encoded by a single family of tandemly clustered genes containing approximately 8 copies of the 3.6 kilobase repeat unit. Transcriptional mapping defines a contiguous 3.3 kilobase region of the repeat unit that en...
