Pathogen and circadian controlled 1 (PCC1) regulates polar lipid content, ABA-related responses, and pathogen defence in Arabidopsis thaliana

Mir, Ricardo ; Hernández, M. Luisa ; Abou-Mansour, Eliane ; Martínez-Rivas, José Manuel ; Mauch, Félix ; Métraux, Jean-Pierre ; León, José

In: Journal of Experimental Botany, 2013, vol. 64, no. 11, p. 3385–3395

Pathogen and Circadian Controlled 1 (PCC1) was previously characterized as a regulator of defence against pathogens and stress-activated transition to flowering. Plants expressing an RNA interference construct for the PCC1 gene (iPCC1 plants) showed a pleiotropic phenotype. They were hypersensitive to abscisic acid (ABA) as shown by reduced germination potential and seedling establishment, as...

A role for β-sitosterol to stigmasterol conversion in plant–pathogen interactions

Griebel, Thomas ; Zeier, Jürgen

In: The Plant Journal, 2010, vol. 63, no. 2, p. 254–268

Upon inoculation with pathogenic microbes, plants induce an array of metabolic changes that potentially contribute to induced resistance or even enhance susceptibility. When analysing leaf lipid composition during the Arabidopsis thaliana–Pseudomonas syringae interaction, we found that accumulation of the phytosterol stigmasterol is a significant plant metabolic process that occurs upon...
