Beckerle, Mary C. | Analysis of the roles of microtubules and actin in erythrophore intracellular motility | The Holocentrus erythrophore, a red pigment cell, represents a model system for the study of organized intracellular transport. We have investigated the possibility that microtubules and actin are integral components of the pigment translocating motility machine. | Actin; Actomyosin; Erythrophore; Pigment | 1983 |

Sperry, John S. | Anatomy of the palm Rhapis excelsa, IX. Xylem structure of the leaf insertion | STEMS OF PERENNIAL PLANTS, particularly trees, represent a considerable investment in biomass. Trees can survive even under the most adverse conditions, but only if the hydraulic integrity of the stem is preserved. A very important and vulnerable part of the stem is the xylem. As water is pulled int... | Palm stems; Palm stem anatomy; Palm leaves; Leaf insertion; Vessel network; Vessel-length distribution; Primary vascular stem tissue; Hydraulic architechture; Water column | 1983 |

Sperry, John S. | Anatomy of the palm Rhapis excelsa, VIII. Vessel network and vessel-length distribution in the stem | THE CONCEPT of the vessel, a conducting unit consisting of a series of vessel elements lined up end to end, has been known for well over a century (e.g., Hartig, 1878). The fact that vessels are of limited length is of considerable functional importance. If a vessel is damaged (for example, by an in... | Palm stems; Palm stem anatomy; Vessel network; Vessel-length distribution; Primary vascular stem tissue; Hydraulic architechture; Water column | 1982 |

Jorgensen, Erik | Axon regeneration genes identified by RNAi screening in C. elegans | Axons of the mammalian CNS lose the ability to regenerate soon after development due to both an inhibitory CNS environment and the loss of cell-intrinsic factors necessary for regeneration. The complex molecular events required for robust regeneration of mature neurons are not fully understood, part... | | 2014-01-01 |

Jorgensen, Erik | Axons break in animals lacking B-spectrin | Axons and dendrites can withstand acute mechanical strain despite their small diameter. In this study, we demonstrate that β-spectrin is required for the physical integrity of neuronal processes in the nematode Caenorhabditis elegans. Axons in β-spectrin mutants spontaneously break. | | 2007 |

Hughes, Kelly T. | Bacterial flagellin-specific chaperone FliS interacts with anti-sigma factor FlgM | Flagella are extracellular organelles that propel bacteria. Each flagellum consists of a basal body, a hook, and a filament. The major protein of the filament is flagellin. To prevent premature polymerization of newly synthesized flagellin molecules, FliS, the flagellin-specific chaperone, binds fla... | | 2014-01-01 |

Olivera, Baldomero M. | Bacteriophage Mu DNA replication in vitro | An in vitro system for bacteriophage Mu DNA replication using lysates on cellophane discs is described. Mu replication was monitored by DNA hybridization. Using a thermoinducible Mu Iysogen, 30-50% of all DNA synthesis in vitro was Mu-specific. | Bacteriophage Mu | 1983 |

Adler, Frederick R. | Balance of terror: an alternative mechanism for competitive trade-offs and its implications for invading species | This article uses models to propose an explanation for three observations in community ecology: the apparent overreaction of prey to attack by specialist predators, the existence of a common trade-off among components of competitive ability in communities of unrelated competitors, and the ability of... | Models; Curve; Native | 1999 |
