Estimation of the relative abundance of different Bacteroides and Prevotella ribotypes in gut samples by restriction enzyme profiling of PCR-amplified 16S rRNA gene sequences

Wood, Jacqueline; Scott, Karen P.; Avguštin, Gorazd; Newbold, C. J.; Flint, Harry J. (1998-10)

We describe an approach for determining the genetic composition of Bacteroides and Prevotella populations in gut contents based on selective amplification of 16S rRNA gene sequences (rDNA) followed by cleavage of the ...

Kulaeva, O. N.; Yakovleva, L. A.; Rakitin, V. Y.; Smith, Aileen; Hall, Michael A.; Burkhanova, E. A.; Kudryakova, N. V. (2001-09-10)

We studied the effects of cytokinin benzyladenine (BA) and ethylene on the senescence in the dark of detached leaves of Arabidopsis thaliana(L.) Heynh wild-type plants and theeti-5mutant, which was described in the literature ...
Ethylene rapidly up-regulates the activities of both monomeric GTP-binding proteins and protein kinase(s) in epicotyls of pea

Moshkov, Igor E.; Hall, Michael A.; Novikova, Galina V.; Smith, Aileen R.; Mur, Luis A. J. (2003-03-06)

It is demonstrated that, in etiolated pea (Pisum sativum) epicotyls, ethylene affects the activation of both monomeric GTP-binding proteins (monomeric G-proteins) and protein kinases. For monomeric G-proteins, the effect ...
Ethylene regulates monomeric GTP-binding protein gene expression and activity in Arabidopsis

Hall, Michael A.; Moshkov, Igor E.; Mur, Luis A. J.; Novikova, Galina V.; Smith, Aileen R. (2003-03-20)

Ethylene rapidly and transiently up-regulates the activity of several monomeric GTP-binding proteins (monomeric G proteins) in leaves of Arabidopsis as determined by two-dimensional gel electrophoresis and autoradiographic ...
Ethylene signal perception and transduction: multiple paradigms?

Moshkov, I. E.; Smith, Aileen R.; Novikova, G. V.; Mur, Luis A. J.; Hall, Michael A. (2001-02)

Current progress on the mechanisms of ethylene signal perception and transduction are reviewed with an emphasis on reconciling data from molecular genetics and from biochemical approaches. It is proposed that there exist ...
Eubacterium pyruvativorans sp nov., a novel non-saccharolytic anaerobe from the rumen that ferments pyruvate and amino acids, forms caproate and utilizes acetate and propionate

Wallace, R. J.; McKain, N.; McEwan, N. R.; Miyagawa, E.; Chaudhary, L. C.; King, T. P.; Walker, N. D.; Apajalahti, J. H. A.; Newbold, C. J. (2003-07)

Two similar Gram-positive rods were isolated from 10(-6) dilutions of ruminal fluid from a sheep receiving a mixed grass hay/concentrate diet, using a medium containing pancreatic casein hydrolysate as sole source of carbon ...

Stolze, M.; Lampkin, Nic H. (2006)
The european market for organic food

Padel, S.; Jasinska, A.; Rippin, M.; Schaack, D.; Willer, H. (Bonn, Frick: IFOAM and FIBL., 2008-02-01)
Eutrophication causes speciation reversal in whitefish adaptive radiations

Vonlanthen, P.; Bittner, D.; Hudson, A. G.; Young, K. A.; Müller, R.; Lundsgaard-Hansen, B.; Roy, D.; Di Piazza, S.; Largiader, C. R.; Seehausen, O. (2012-02-16)

Species diversity can be lost through two different but potentially interacting extinction processes: demographic decline and speciation reversal through introgressive hybridization. To investigate the relative contribution ...
Eutrophication processes and trophic interactions in a shallow estuary: prelinimary results based on stable isotope analysis (delta13C and delta15N)

Abreu, Paulo Cesar; Costa, César S. B.; Bemvenuti, Carlos; Odebrecht, Clarisse; Graneli, Wilhelm; Anesio, Alexandre M. (2006-04-01)

Stable isotopes ratios (δ13C and δ15N) were measured in primary producers and consumers of two bays with contrasting eutrophic conditions in the Patos Lagoon estuary, southern Brazil: the Justino bay, a more pristine ...
