Gesteland, Raymond F. | Translation of Rl7 RNA fragments | Examination of the events during infection of cells by RNA phages reveals phemonomena that are surprisingly complex for a virus that has only enough information to code for three to four proteins. The coat protein is synthesized at a rapid rate through most of the infectious cycle making it the pre... | Electrophoresis; RNA, Messenger; Peptide Biosynthesis; Kinetics | 1969 |

Hultine, Kevin; Sperry, John S. | Transpiration and hydraulic strategies in a piñon-juniper woodland | Anthropogenic climate change is likely to alter the patterns of moisture availability globally. The consequences of these changes on species distributions and ecosystem function are largely unknown, but possibly predictable based on key ecophysiological differences among currently coexisting species... | Drought; Hydraulic transport model; Juniperus osteosperma; Plant water use; Sap flux; Species distributions | 2008 |

Jorgensen, Erik | Trio's Rho-specific GEF domain is the missing Gaq effector in C. elegans | The Gaq pathway is essential for animal life and is a central pathway for driving locomotion, egg laying, and growth in Caenorhcibditis elegans, where it exerts its effects through EGL-8 (phospholipase CB [PLCB]) and at least one other effector. To find the missing effector, we performed forward ... | | 2007-11-01 |

Coley, Phyllis D. | Tritrophic interactions in tropical versus temperate communities | The latitudinal gradient in diversity is one of the oldest (e.g., Wallace, 1878) and most obvious trends in ecology, and a wealth of literature is devoted to understanding both the causes and consequences of this gradient (Dobzhansky, 1950; also reviewed by Rohde, 1992). Given the enormous latitudi... | Tritrophic interactions; Trophic cascades; Herbivory; Tropical communities; Temperate communities | 2002 |

Davidson, Diane W. | Tropical arboreal ants: why so abundant? | ANTS ARE AMONG the most numerous and readily observed arthropods of tropical forests. Indeed, based on their standing biomass and many effects on other species, ants (Formicidae) are arguably the dominant arthropod family in the canopies of lowland rain forest trees (Tobin 1995). Others have tried t... | Arboreal ants; Tropics | 1996 |

Shapiro, Michael D. | Turnover of sex chromosomes in the stickleback fishes (Gastrosteidae) | Diverse sex-chromosome systems are found in vertebrates, particularly in teleost fishes, where different systems can be found in closely related species. Several mechanisms have been proposed for the rapid turnover of sex chromosomes, including the transposition of an existing sex-determination gen... | Sex determination; Gasterosteus aculeatus; Gasterosteus wheatlandi; Pungitius pungitius; Culaea inconstans; Apeltes quadracus; Gasterosteidae | 2009-02-20 |

Bohs, Lynn A. | Two new species from the brevantherum clade of solanum (solanaceae) from eastern Brazil | Two new species of Solanum (Solanaceae) from eastern Brazil are described. Solanum anisocladum Giacomin & Stehmann is similar to S. megalochiton Mart., but differs by the indument of the adaxial leaf surface, which is composed of long porrect-stellate and unbranched trichomes. It also has a more rob... | | 2013-01-01 |

Jorgensen, Erik | UNC-11, a Caenorhabditis elegans AP180 homologue, regulates the size and protein composition of synaptic vesicles | The unc-11 gene of Caenorhabditis elegans encodes multiple isoforms of a protein homologous to the mammalian brain-specific clathrin-adaptor protein AP180. The UNC-11 protein is expressed at high levels in the nervous system and at lower levels in other tissues. In neurons, UNC-11 is enriched at pr... | Caenorhabditis elegans; Synaptic vesicles; unc-11; Synaptobrevin; Endocytosis | 1999 |

Jorgensen, Erik | UNC-41/stonin functions with AP2 to recycle synaptic vesicles in Caenorhabditis elegans | The recycling of synaptic vesicles requires the recovery of vesicle proteins and membrane. Members of the stonin protein family (Drosophila Stoned B, mammalian stonin 2) have been shown to link the synaptic vesicle protein synaptotagmin to the endocytic machinery. Here we characterize the unc-41 gen... | | 2012-01-01 |

Farmer, Colleen G. | Unidirectional pulmonary airflow patterns in the savannah monitor lizard | The unidirectional airflow patterns in the lungs of birds have long been considered a unique and specialized trait associated with the oxygen demands of flying, their endothermic metabolism1 and unusual pulmonary architecture2,3. However, the discovery of similar flow patterns in the lungs of crocod... | | 2014-02-20 |

Gesteland, Raymond F.; Atkins, John F.; Tuohy, Therese M. | Uninterrupted translation through putative 12-nucleotide coding gap in sequence of carA: business as usual | Previous work of others reported an untranslated stretch of 12 nucleotides in the 5' coding sequence of carA from Pseudomonas aeruginosa. However, N-terminal protein sequencing of carA-lacZ translational fusions shows that these 12 nucleotides are normally translated in a continuous triplet manner, ... | Base Sequence; Protein Biosynthesis; Sequence Deletion | 1994 |

Brunstetter, Duncan Matthew; Blair, David F. | Unlocking the switching of a nanomotor | Many pathogens use flagella as a means of locomotion. Pairs of Fli M residues were mutated and tested in the presence of repellent (forcing the motor to tumble) and differences in crosslinking were observed. Of those species, some (e.coli, salmonella etc.) can spin their flagella in 2 different di... | Pathogens; Flagella; Nanotechnology; Nanomotor; Trapeze Interactive Poster | 2010-03-15 |
