Shooting control by brassinosteroids: metabolomic analysis and effect of brassinazole on Malus prunifolia, the Marubakaido apple rootstock (2009)

Pereira-Netto, Adaucto B., Roessner, Ute, Fujioka, Shozo, Bacic, Antony, Asami, Tadao, Yoshida, Shigeo, ...

To help unravel the role of brassinosteroids (BRs) in the control of shooting, we treated the shoots of Marubakaido apple rootstock (Malus prunifolia (Willd.) Borkh cv. Marubakaido) with brassinolide...

Metabolite Profiling Reveals Distinct Changes in Carbon and Nitrogen Metabolism in Phosphate-Deficient Barley Plants (Hordeum vulgare L.) (2008)

Huang, Chun Y., Roessner, Ute, Eickmeier, Ira, Genc, Yusuf, Callahan, Damien L., Shirley, Neil, ...

Plants modify metabolic processes for adaptation to low phosphate (P) conditions. Whilst transcriptomic analyses show that P deficiency changes hundreds of genes related to various metabolic...

Changes in the Sugarcane Metabolome with Stem Development. Are They Related to Sucrose Accumulation? (2007)

Glassop, Donna, Roessner, Ute, Bacic, Antony, Bonnett, Graham D.

Sucrose content increases with internode development down the stem of sugarcane. In an attempt to determine which other changes in metabolites may be linked to sucrose accumulation gas...

Antisense Repression of Hexokinase 1 Leads to an Overaccumulation of Starch in Leaves of Transgenic Potato Plants But Not to Significant Changes in Tuber Carbohydrate Metabolism1

Veramendi, Jon, Roessner, Ute, Renz, Andreas, Willmitzer, Lothar, Trethewey, Richard N.

Potato (Solanum tuberosum L.) plants transformed with sense and antisense constructs of a cDNA encoding the potato hexokinase 1 (StHK1) exhibited altered enzyme activities and expression of StHK1...

The Sucrose Analog Palatinose Leads to a Stimulation of Sucrose Degradation and Starch Synthesis When Supplied to Discs of Growing Potato Tubers1

Fernie, Alisdair R., Roessner, Ute, Geigenberger, Peter

In the present paper we investigated the effect of the sucrose (Suc) analog palatinose on potato (Solanum tuberosum) tuber metabolism. In freshly cut discs of growing potato tubers, addition of 5 mm...

Analysis of the Compartmentation of Glycolytic Intermediates, Nucleotides, Sugars, Organic Acids, Amino Acids, and Sugar Alcohols in Potato Tubers Using a Nonaqueous Fractionation Method1

Farré, Eva M., Tiessen, Axel, Roessner, Ute, Geigenberger, Peter, Trethewey, Richard N., Willmitzer, Lothar

The compartmentation of metabolism in heterotrophic plant tissues is poorly understood due to the lack of data on metabolite distributions and fluxes between subcellular organelles. The main reason...

High-Resolution Metabolic Phenotyping of Genetically and Environmentally Diverse Potato Tuber Systems. Identification of Phenocopies

Roessner, Ute, Willmitzer, Lothar, Fernie, Alisdair R.

We conducted a comprehensive metabolic phenotyping of potato (Solanum tuberosum L. cv Desiree) tuber tissue that had been modified either by transgenesis or exposure to different environmental...

Antisense Inhibition of Threonine Synthase Leads to High Methionine Content in Transgenic Potato Plants1

Zeh, Michaela, Casazza, Anna Paola, Kreft, Oliver, Roessner, Ute, Bieberich, Katrin, Willmitzer, Lothar, ...

Methionine (Met) and threonine (Thr) are members of the aspartate family of amino acids. In plants, their biosynthetic pathways diverge at the level of O-phosphohomo-serine (Ser). The enzymes...

An Investigation of Boron Toxicity in Barley Using Metabolomics1[W]

Roessner, Ute, Patterson, John H., Forbes, Megan G., Fincher, Geoffrey B., Langridge, Peter, Bacic, Anthony

Boron (B) is an essential micronutrient that affects plant growth at either deficient or toxic concentrations in soil. The aim of this work was to investigate the adaptation of barley (Hordeum...

Metabolic responses to salt stress of barley (Hordeum vulgare L.) cultivars, Sahara and Clipper, which differ in salinity tolerance

Patterson, John H., Newbigin, Ed, Tester, Mark, Bacic, Antony, Roessner, Ute

Plants show varied cellular responses to salinity that are partly associated with maintaining low cytosolic Na+ levels and a high K+/Na+ ratio. Plant metabolites change with elevated Na+, some...
