... this ancient regulatory mechanism has been adapted in higher plants. Drawing comparisons with the substantial knowledge base around TOR kinase signalling in fungal and animal systems, functional aspects of this pathway in plants are reviewed. Both conserved and divergent elements are discussed in relation...

...Hong-Wei Xue; Xu Chen; Yu Mei As an important metabolic pathway, phosphatidylinositol metabolism generates both constitutive and signalling molecules that are crucial for plant growth and development. Recent studies using genetic and molecular approaches reveal the important roles of phospholipid...

...Michael J. Gardner; Katharine E. Hubbard; Carlos T. Hotta; Antony N. Dodd; Alex A. R. Webb Plants, like all eukaryotes and most prokaryotes, have evolved sophisticated mechanisms for anticipating predictable environmental changes that arise due to the rotation of the Earth on its axis...

... neurodegenerative disorder plant protein kinase B (PKB) Important clues came from the crystal structures (see the green structure in Figure 1 ), which showed that each 14-3-3 polypeptide contains nine helices, arranged to form an almost right-angled corner. Two 14-3-3 subunits associate strongly...

..., glycerophosphoethanolamine, glycerophosphoglycerol, glycerophosphoserine and bis-glycerophosphoglycerol), releasing sn -glycerol 3-phosphate and the corresponding alcohol. In a previous study, we demonstrated the existence of a novel GPX-PDE in the cell walls and vacuoles of plant cells. Since no GPX-PDE had been identified...

... all the properties of the ferritin subunits described so far, non-exhaustively, from various plant species. All are predicted to be targeted to the plastids, which is consistent with the existence of a putative transit peptide at their N-terminal extremity. They also all possess a conserved extension...

... to manganese uptake in yeast. Some of the NRAMP proteins in mammals and in yeast are capable of transporting metal ions, including iron. In plants, iron transport was shown to require a reduction/Fe(II) transport system. In Arabidopsis thaliana this process involves the IRT1 and Fro2 genes. Here we report...

... and a pI of 8.53. An uncharged region is observed at its N-terminus but no myristoylation consensus site is present. Taken together, these results, coupled with previous biochemical evidence, prove that NFR belongs to the b 5 R class and document b 5 R from a plant at the molecular level for the first time...
