Journal ArticleDOI
QUASIMODO1 Encodes a Putative Membrane-Bound Glycosyltransferase Required for Normal Pectin Synthesis and Cell Adhesion in Arabidopsis
Sophie Bouton,Edouard Leboeuf,Grégory Mouille,Marie-Thérèse Leydecker,Joël Talbotec,Fabienne Granier,Marc Lahaye,Herman Höfte,Hoai-Nam Truong +8 more
TL;DR: Evidence is presented for the possible involvement of a glycosyltransferase of this family in the synthesis of pectic polysaccharides, suggesting that other members of this large multigene family in Arabidopsis also may be important for pectin biosynthesis.
Journal ArticleDOI
Regulation of nitrate and nitrite reductase expression in Nicotiana plumbaginifolia leaves by nitrogen and carbon metabolites.
TL;DR: The characterization of transgenic plants expressing either a NR cDNA controlled by the 35S CaMV promoter or a transcriptional fusion between the tobacco nia1 (NR structural gene) promoter and the beta-glucuronidase reporter gene, led us to conclude that C metabolite control is taking place at the transcriptional level.
Journal ArticleDOI
Expression of leaf nitrate reductase genes from tomato and tobacco in relation to light-dark regimes and nitrate supply.
Fabienne Galangau,Françoise Daniel-Vedele,Thérèse Moureaux,Marie-France Dorbe,Marie-Thérèse Leydecker,Michel Caboche +5 more
TL;DR: The influence of light-dark cycles and nitrate supply on nitrate reductase (NR) mRNA levels was studied in two plant species, tobacco and tomato, to suggest that the availability of nitrogen affects the expression of NR activity at the transcriptional as well as at the post-transcriptional levels.
Journal ArticleDOI
Nitrite accumulation and nitric oxide emission in relation to cellular signaling in nitrite reductase antisense tobacco.
Y Morot-Gaudry-Talarmain,P Rockel,Thérèse Moureaux,Isabelle Quilleré,Marie-Thérèse Leydecker,Werner M. Kaiser,Jean-François Morot-Gaudry +6 more
TL;DR: Increased protein tyrosine nitration in clone 271 suggests that high NO· production resulted in increased peroxynitrite (ONOO–) formation, which is both involved in regulation of activity and stability of enzymes.
Journal ArticleDOI
Nitrate-reductase expression is under the control of a circadian rhythm and is light inducible in Nicotiana tabacum leaves.
TL;DR: The results indicate the circadian rhythmicity and light dependence of NR expression and the levels of NR mRNA, protein and activity in leaves all became negligible, and light reinduced them rapidly.
