Tsuneda, A., Currah, R.S., Tsuneda, I.
Details of the development of endoconidia were basically the same in Endoconidioma populi and Phaeotheca fissurella. In both species, endoconidiogenesis involved (i) subdivision of conidiogenous mother cells by septation to form two to several daughter cells; (ii) accumulation of an electrondense...

Endogenous hypothalamic somatostatins differentially regulate growth hormone secretion from goldfish pituitary somatotropes in vitro
Download2003
Davis, P.J., Peter, R.E., Chang, J.P., Graves, C., Smith, S., Rivier, J.E., Yunker, W.Y., Unniappan, S.
Using Southern blot analysis of RT-PCR products, mRNA for three different somatostatin (SS) precursors (PSS-I, -II, and -III), which encode for SS14, goldfish brain (gb)SS28, and [Pro2]SS14, respectively, were detected in goldfish hypothalamus. PSS-I and -II mRNA, but not PSS-III mRNA, were also...

Endogenous melanocortin antagonist in fish: Structure, brain mapping and regulation by fasting of the goldfish agouti-related protein gene
Download2003
Cerdá-Reverter, J.M., Peter, R.E.
Agouti-related protein (AGRP) is a naturally occurring antagonist of melanocortin. In mammals, central AGRP expression is restricted to the arcuate nucleus in which it plays a key role in the control of energy balance by antagonizing melanocortin effects at melanocortin 4 receptors. In goldfish,...

Endomembrane system of aspen roots plays a key role in defense against a common fungal endophyte Cryptosporiopsis radicicola
Download2009
Tsuneda, I., Wang, W., Currah, R.S., Tsuneda, A.
The host-endophyte interaction between roots of aspen (Populus tremuloides) andCryptosporiopsis radicicola was examined primarily by transmission electron microscopy. Hyphae growing on the exterior of the inoculated roots had a thick, electron-dense, adhesive sheath. At hyphal contact and...

Enhanced low oxygen survival in Arabidopsis through increased metabolic flux in the fermentative pathway
Download2003
DePauw, M., Good, A. G., Dennis, E. S., Dolferus, R., Ismond, K. P.
We manipulated the enzyme activity levels of the alcohol fermentation pathway, pyruvate decarboxylase (PDC), and alcohol dehydrogenase (ADH) in Arabidopsis using sense and antisense overexpression of the corresponding genes (PDC1, PDC2, and ADH1). Transgenic plants were analyzed for levels of...

Enhancing productive capacity in the Canadian Arctic: Assessing the effectiveness of instream habitat structures in habitat compensation
Download2004
We examined the effectiveness of physical habitat structures (ramps, V-weirs, vanes, and groins) at increasing the productive capacity of a newly created 3.4-km artificial stream in the Barrenlands region of the Northwest Territories, Canada. We quantified changes in fish density and growth in...

Wilson, A.J., Pemberton, J.M., Coltman, D.W., Kruuk, L.E.B., Pilkington, J.G., Mifsud, D.V., Clutton-Brock, T.H.
There has recently been great interest in applying theoretical quantitative genetic models to empirical studies of evolution in wild populations. However, while classical models assume environmental constancy, most natural populations exist in variable environments. Here, we applied a novel...

Epulorhiza inquilina sp. nov. from Platanthera (Orchidaceae) and a key to Epulorhiza species
Download1997
McInnis, T. M., Currah, R. S., Zettler, L. W.
Abstract: Epulorhiza inquilina sp. nov. is described from the mycorrhizas of mature plants of Platanthera clavellata, P. cristata and P. integrilabia, coexisting terrestrial orchids native to bogs in the southern Appalachians. The new taxon was isolated consistently and exclusively from these...

The goal of this group project has been to coordinate and bring up-to-date information on all genes of Escherichia coli K-12. Annotation of the genome of an organism entails identification of genes, the boundaries of genes in terms of precise start and end sites, and description of the gene...

Establishing a fossil record for the perianthless Piperales: Saururus tuckerae sp. nov. (Saururaceae) from the Middle Eocene Princeton Chert
Download2007
Investigations of small permineralized flowers from the Middle Eocene Princeton Chert, British Columbia, Canada have revealed that they represent an extinct species of Saururus. Over 100 flowers and one partial inflorescence were studied, and numerous minute perianthless flowers are borne in an...
