Singlet oxygen ( 1 O 2 ), the major reactive oxygen species (ROS) produced in chloroplasts, has been demonstrated recently to be a highly versatile signal that induces various stress responses. In the fluorescent ( flu ) mutant, its release causes se

In plants, highly reactive singlet oxygen ((1)O(2)) is known to inhibit photosynthesis and to damage the cell as a cytotoxin. However, more recent studies have also proposed (1)O(2) as a signal. In plants under stress, not only (1)O(2) but also other

Singlet oxygen ((1)O2)-mediated signaling has been established in the conditional fluorescent (flu) mutant of Arabidopsis. In the dark, the flu mutant accumulates free protochlorophyllide (Pchlide), a photosensitizer that in the light generates (1)O2

Regulation of tetrapyrrole biosynthesis in higher plants has been attributed to negative feedback control. Two effectors of feedback inhibition have been identified, heme and the FLU protein. Inhibition by heme implicates the Fe-branch via regulation

Retrograde plastid-to-nucleus signaling tightly controls and coordinates the nuclear and plastid gene expression that is required for plastid biogenesis and chloroplast activity. As chloroplasts act as sensors of environmental changes, plastid-derive

*† ‡ SUMMARY The process of chloroplast biogenesis requires a multitude of pathways and processes to establish chloroplast function. In cotyledons of seedlings, chloroplasts develop either directly from proplastids (also named eoplasts) or, if ge

Various mutant screens have been undertaken to identify constituents involved in the transmission of signals from the plastid to the nucleus. Many of these screens have been performed using carotenoid-deficient plants grown in the presence of norflur

Here, we describe the snowy cotyledon3 (sco3-1) mutation, which impairs chloroplast and etioplast development in Arabidopsis thaliana seedlings. SCO3 is a member of a largely uncharacterized protein family unique to the plant kingdom. The sco3-1 muta

Shortly after the release of singlet oxygen ( 1 O 2 ), drastic changes in nuclear gene expression occur in the conditional flu mutant of Arabidopsis that reveal a rapid transfer of signals from the plastid to the nucleus. In contrast to retrograde co

Programmed cell death (PCD) plays an important role during the life cycle of higher organisms. Although several regulatory mechanisms governing PCD are thought to be conserved in animals and plants, light-dependent cell death represents a form of PCD
