Iron (Fe) is essential for life because of its role in protein cofactors. Photosynthesis, in
particular photosynthetic electron transport, has a very high demand for Fe cofactors. Fe is …

▪ Abstract Plants utilize several families of photoreceptors to fine-tune growth and
development over a large range of environmental conditions. The UV-A/blue light sensing …

A photosynthetic organism is subjected to photo-oxidative stress when more light energy is
absorbed than is used in photosynthesis. In the light, highly reactive singlet oxygen can be …

Summary Cadmium (Cd) and lead (Pb) are widespread pollutants that are toxic to plant
growth. The expression of AtPDR8 was upregulated in cadmium‐or lead‐treated …

The ABC superfamily comprises both membrane-bound transporters and soluble proteins
involved in a broad range of processes, many of which are of considerable agricultural …

Arabidopsis thaliana is a host to the powdery mildew Erysiphe cichoracearum and nonhost
to Blumeria graminis f. sp hordei, the powdery mildew pathogenic on barley (Hordeum …

The solubilization and long-distance allocation of iron between organs and tissues, as well
as its subcellular compartmentalization and remobilization, involve various chelation and …

The conditional fluorescent (flu) mutant of Arabidopsis accumulates the photosensitizer
protochlorophyllide in the dark. After a dark-to-light shift, the generation of singlet oxygen, a …

Tetrapyrroles such as chlorophylls and bacteriochlorophylls play a fundamental role in the
energy absorption and transduction activities of photosynthetic organisms. Because of these …

The ATP-binding cassette (ABC) protein superfamily is one of the largest known, with over
120 members in both Arabidopsis thaliana and rice (Oryza sativa). Most, but not all, ABC …
