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 |

Gesteland, Raymond F.; Atkins, John F. | Frameshifting in gene 10 of bacteriophage T7 | Gene 10 of bacteriophage T7, which encodes the most abundant capsid protein, has two products: a major product, 10A (36 kDa), and a minor product, 10B (41 kDa). 10B is produced by frameshifting into the -1 frame near the end of the 10A coding frame and is incorporated into the capsid. The frameshift... | Frameshifting; Bacteriophage T7; RNA, Viral; Gene Expression | 1991 |

Ehleringer, James R.; Rickart, Eric Allan; Dearing, Maria-Denise | Stable isotope ratios (?15N AND ?13C) of syntopic shrews (SOREX) | Local species richness in shrew (Soricidae) assemblages is often high, and the mechanisms of ecological separation remain relatively unexplored. In this study, hair samples from 6 species of Sorex in 3 separate assemblages were analyzed for stable carbon (13C/12C) and nitrogen (15N/14N) isotope rati... | | 2004 |

Seger, Jon | Ideas in ecology | The word "ecology" means different things to different people. For example, during the last 25 years or so the word has been used to label attitudes, life-styles, consumer goods, political parties, and college courses. In the 1960s one university renamed its "Home Economics" course "Home Ecology."... | Behavioral ecology; Population ecology | 1986 |

Capecchi, Mario R. | Lessons from angiotensin-converting enzyme-deficient mice | Since the first description of renin by Tigerstedt and Bergman [1] in 1898, many papers have described the biochemistry and physiological roles of the reninangiotensin system [2]. A critical component of this system is angiotensin-converting enzyme (ACE), a peptidase which cleaves the inactive pep... | | 1996 |

Capecchi, Mario R. | Removing the vertebrate-specific TBP N terminus disrupts placental beta2m-dependent interactions with the maternal immune system | Mammalian TBP consists of a 180 amino acid core that is common to all eukaryotes, fused to a vertebrate-specific N-terminal domain. We generated mice having a modified tbp allele, tbp(DeltaN), that produces a version of TBP lacking 111 of the 135 vertebrate-specific amino acids. Most tbp(DeltaN/Delt... | Alleles; Animals, Genetically Modified; Binding Sites; Embryonic and Fetal Development; Evolution, Molecular; Female; Fetus; Immune Tolerance; Male; Mice; Mutation; ATA-Box Binding Protein | 2002-07-12 |

Ehleringer, James R. | Carbon isotope discrimination in the C4 shrub Atriplex confertifolia along a salinity gradient | Carbon isotope discrimination (∆) was measured for leaves of Atriplex confertifolia along a salinity gradi~ ent in northern Utah. Over this gradient, the variation of ∆ values was high for a C4 species, and the ∆ values were positively correlated with salinity in both years of the study.

Bastiani, Michael | Pathfinding by neuronal growth cones in grasshopper embryos I. Divergent choices made by the growth cones of sibling neurons | We are interested in how the growth cones of identified neurons navigate in the central nervous system of the grasshopper embryo.

Farmer, Colleen G. | Reproduction: the adaptive significance of endothermy | A central theme raised by Angilletta and Sears is that the energetic cost of endothermy is too enormous to be offset by the benefits that thermogenesis could provide for reproduction. Angilletta and Sears suggest that parents would have been better off producing additional offspring with the energy ... | Parental care; Incubation; Metabolism | 2003 |

Beckerle, Mary C. | CRP1, a LIM domain protein implicated in muscle differentiation, interacts with α-actinin | Members of the cysteine-rich protein (CRP) family are LIM domain proteins that have been implicated in muscle differentiation. One strategy for defining the mechanism by which CRPs potentiate myogenesis is to characterize the repertoire of CRP binding partners. | CRP1; Cysteine-rich proteins; Actinin; Protein-protein interactions; LIM domains | 1997 |

Goller, Franz | Inspiratory muscle activity during singing in zebra finches and cowbirds | Singing is produced by an intricate coordination of vocal (syringeal) and respiratory muscles. Expiratory muscle activity is associated with the production of notes and syllables, which are separated by silent intervals, negative air sac pressure, and inspiratory air flow. In order to study the mus... | Minibreath; Expiration; Inspiration | 1997 |

Capecchi, Mario R. | How close are we to implementing gene targeting in animals other than the mouse? | Describes several significant contributions that bring us much closer to extending ‘‘gene targeting'' to mammalian species other than the mouse.
