Publikováno v: PLoS ONE, Vol 9, Iss 8, p e104194 (2014)

The evolutionarily conserved target of rapamycin complex 1 (TORC1) controls growth-related processes such as protein, nucleotide, and lipid metabolism in response to growth hormones, energy/ATP levels, and amino acids. Its deregulation is associated

The biogenesis of photosynthetic membranes relies on galactoglycerolipids, which are synthesized via pathways that are dispatched over several cell compartments. This membrane biogenesis requires both trafficking of lipid intermediates and a tight ho

Glycerolipid biosynthesis and chloroplast biogenesis

Chloroplast membranes are enriched with galactoglycerolipids, monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol (DGDG). These galactolipids do not contain phosphorus and chloroplast membranes are therefore very poor in phospholipids,

International audience; Phosphatidic acid (PA) is a precursor metabolite for phosphoglycerolipids and also for galactoglycerolipids, which are essential lipids for formation of plant membranes. PA has in addition a main regulatory role in a number of

FEBS Letters, 2008, 582 (5), pp.685-90. ⟨10.1016/j.febslet.2008.01.039⟩

Under phosphate deprivation, higher plants change their lipid composition and recycle phosphate from phospholipids. A phospholipase D, PLDzeta2, is involved in this recycling and in other cellular functions related to plant development. We investigat
