Abstract excerpt

Polysaccharides are the main components present in plant cell walls. They form a network that is dynamically modified during growth and upon both abiotic and biotic stress. We investigated how the cell wall of Arabidopsis rosettes is remodeled during periods of dark-induced starvation in the wild type and in plastidic phosphoglucomutase (pgm) mutants, which suffer from periodic starvation due to starch...
