Role of phosphatidic acid in plant galactolipid synthesis

Dubots, Emmanuelle ; Botté, Cyrille ; Boudière, Laurence ; Yamaryo-Botté, Yoshiki ; Jouhet, Juliette ; Maréchal, Eric ; Block, Maryse A.

In: Biochimie, 2012, vol. 94, no. 1, p. 86-93

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 developmental processes notably in the response of the plant to environmental stresses. We review here the different pools of PA dispatched at different locations in the...

Functional significance of triazine-herbicide resistance in defence of Senecio vulgaris against a rust fungus

Salzmann, Daniel ; Handley, Richard J. ; Müller-Schärer, Heinz

In: Basic and Applied Ecology, 2008, vol. 9, no. 5, p. 577-587

We investigated the functional significance of plant performance (dry mass, photosynthesis) in plant defence (resistance and tolerance) against pathogen infection, and potential negative cross-resistance between herbicide resistance and plant defence against disease. We compared isonuclear triazine-herbicide-resistant (TR) and -susceptible (TS) biotypes of Senecio vulgaris, in the presence and...
