The Oxa2 protein of Neurospora crassa plays a critical role in the biogenesis of cytochrome oxidase and defines a ubiquitous subbranch of the Oxa1/YidC/Alb3 protein family
Download2004
Herrmann, J.M., Nargang, F.E., Neupert, W., Funes, S.
Proteins of the Oxa1/YidC/Alb3 family mediate the insertion of proteins into membranes of mitochondria, bacteria, and chloroplasts. Here we report the identification of a second gene of the Oxa1/YidC/Alb3 family in the genome of Neurospora crassa, which we have named oxa2. Its gene product, Oxa2,...

The Peridial Development and Dehiscence Mechanism of Cryptendoxyla hypophloia, a Cleistothecial Ascomycete Isolated from the Bodies of Arthropods
Download2004
Currah, R.S., Greif, M.D., Tsuneda, A.
Cryptendoxyla hypophloia is a rarely reported cleistothecial ascomycete that has a cephalothecoid peridium comprising six to eight plates that split apart at maturity to expose the ascospores. Three new isolates from the bodies of live-trapped insects represent circumstantial evidence supporting...

Sponges have become the focus of studies on molecular evolution and the evolution of animal body plans due to their ancient branching point in the metazoan lineage. Whereas our former understanding of sponge function was largely based on a morphological perspective, the recent availability of the...

The probable association of feather mites of the genus Ingrassia (Analgoidea: Xolalgidae) with the blue penguin Eudyptula minor (Aves: Sphenisciformes) in Australia.
Download2008
A new feather mite species, Ingrassia eudyptula n. sp. (Xolalgidae: Ingrassiinae), is described from the blue penguin Eudyptula minor (J. B. Forster, 1781) in Australia. This is the first description of a feather mite species from representatives of the avian order Sphenisciformes, which had...

The procambium specification gene Oshox1 promotes polar auxin transport capacity and reduces its sensitivity toward inhibition
Download2002
Meijer, A. H., Reub, S., Boot, K. J. M., Scarpella, E.
The auxin-inducible homeobox gene Oshox1 of rice (Oryza sativa) is a positive regulator of procambial cell fate commitment, and its overexpression reduces the sensitivity of polar auxin transport (PAT) to the PAT inhibitor 1-N-naphthylphthalamic acid (NPA). Here, we show that wild-type rice...

The Role of Hydropteris pinnata gen. et. sp. nov. In Reconstructing the cladistics of Heterosporous Ferns.
Download1994
Large segments of intact plants that represent a heterosporous fern have been discovered within an aquatic plant community from the Late Cretaceous St. Mary River Formation near Cardston in southern Alberta, Canada. Branching rhizomes of Hydropteris pinnata gen. et sp. nov. are 1-2 mm wide. They...

The role of terrestrial vegetation in atmospheric Hg deposition: Pools and fluxes of spike and ambient Hg from the METAALICUS experiment
Download2012
Graydon, J.A., Harris, R., St. Louis, V., Sandilands, K.A., Rudd, J.W.M., Kelly, C.A., Richardson, M., Emmerton, C.A., Lindberg, S.E., Tate, M.T., Asmath, H., Krabbenhoft, D.P.
As part of the Mercury Experiment to Assess Atmospheric Loading in Canada and the U.S. (METAALICUS), different stable Hg(II) isotope spikes were applied to the upland and wetland areas of a boreal catchment between 2001 and 2006 to examine retention of newly deposited Hg(II). In the present...

Müller-Reichert, T., Greenan, G., O'Toole, E., Srayko, M., Lange, K.I.
As part of a multi-subunit ring complex, γ-tubulin has been shown to promote microtubule nucleation both in vitro and in vivo, and the structural properties of the complex suggest that it also seals the minus ends of the polymers with a conical cap. Cells depleted of γ-tubulin, however, still...
