Journal ArticleDOI
Sugar-induced increases in trehalose 6-phosphate are correlated with redox activation of ADPglucose pyrophosphorylase and higher rates of starch synthesis in Arabidopsis thaliana
John E. Lunn,Regina Feil,Janneke H.M. Hendriks,Yves Gibon,Rosa Morcuende,Daniel Osuna,Wolf-Rüdiger Scheible,Petronia Carillo,Mohammad-Reza Hajirezaei,Mark Stitt +9 more
TL;DR: It is found that rising sugar levels in plants are accompanied by increases in the level of Tre6P, redox activation of AGPase and the stimulation of starch synthesis in vivo, and this results indicate that Tre 6P acts as a signalling metabolite of sugar status in plants.
Journal ArticleDOI
Root exudation of sugars, amino acids, and organic acids by maize as affected by nitrogen, phosphorus, potassium, and iron deficiency
Lilia C. Carvalhais,Lilia C. Carvalhais,Paul G. Dennis,Paul G. Dennis,Dmitri Fedoseyenko,Dmitri Fedoseyenko,Mohammad-Reza Hajirezaei,Rainer Borriss,Nicolaus von Wirén +8 more
TL;DR: In this article, root exudates from axenically grown maize plants exposed to N, K, P, or Fe deficiency showed a higher release of glutamate, glucose, ribitol, and citrate from Fe-deficient plants while P deficiency stimulated the release of c-aminobutyric acid and carbohydrates.
Journal ArticleDOI
Increased potato tuber size resulting from apoplastic expression of a yeast invertase
Uwe Sonnewald,Mohammad-Reza Hajirezaei,Jens Kossmann,Arnd G. Heyer,Richard N. Trethewey,Lothar Willmitzer +5 more
TL;DR: The role of sucrose cleavage in determining sink strength in potato was investigated by generating transgenic potato plants that expressed a yeast invertase in either the cytosol or apoplast of tubers.
Journal ArticleDOI
Combined expression of glucokinase and invertase in potato tubers leads to a dramatic reduction in starch accumulation and a stimulation of glycolysis.
Richard N. Trethewey,Peter Geigenberger,K. Riedel,Mohammad-Reza Hajirezaei,Uwe Sonnewald,Mark Stitt,Jorg W. Riesmeier,Lothar Willmitzer +7 more
TL;DR: It is concluded that the expression of invertase in potato tubers leads to an increased flux through the glycolytic pathway at the expense of starch synthesis and that heterologous overexpression of glucokinase enhances this change in partitioning.
Journal ArticleDOI
RNAi-mediated tocopherol deficiency impairs photoassimilate export in transgenic potato plants.
Daniel Hofius,Mohammad-Reza Hajirezaei,Michael Geiger,Henning Tschiersch,Michael Melzer,Uwe Sonnewald +5 more
TL;DR: Evidence is provided that tocopherol deficiency leads to impaired photoassimilate export from source leaves in both monocot and dicot plant species and significant differences among C3 plants in response to tocop herol reduction are suggested.
