Abstract excerpt
Enhanced levels of singlet oxygen ((1)O(2)) in chloroplasts trigger programmed cell death. The impact of (1)O(2) production in chloroplasts was monitored first in the conditional fluorescent (flu) mutant of Arabidopsis thaliana that accumulates (1)O(2) upon a dark/light shift. The onset of (1)O(2) production is rapidly followed by a loss of chloroplast integrity that precedes the rupture of the central vacuole...
