Chlorophyll b is synthesized by the oxidation of a methyl group on the B ring of a tetrapyrrole molecule to a formyl group by chlorophyllide a oxygenase (CAO). The full-length CAO from Arabidopsis (Arabidopsis thaliana) was overexpressed in tobacco (Nicotiana tabacum) that grows well at light
Chlorophyll degradation plays important roles in leaf senescence including regulation of degradation of chlorophyll-binding proteins. Although most genes encoding enzymes of the chlorophyll degradation pathway have been identified, the regulation of their activity has not been fully understood.
Experiments were conducted on Nicotiana tabacum, L. to study the relation in the grana among chlorophylls, carotenoids, and proteins. The effect of iron chlorosis on protein and pigment synthesis was studied at different stages of chlorosis using glycine-U-C(14). Pigments were separated by thin
Oxygenic photosynthetic organisms evolved mechanisms for thermal dissipation of energy absorbed in excess to prevent formation of reactive oxygen species. The major and fastest component, called non-photochemical quenching, occurs within the photosystem II antenna system by the action of two
The Arabidopsis LSD1 and LOL1 proteins both contain three conserved zinc finger domains and have antagonistic effects on plant programmed cell death (PCD). In this study, a rice (Oryza sativa) functional homolog of LSD1, designated OsLSD1, was identified. The expression of OsLSD1 was light-induced
Selective inhibition of gene expression by antisense oligodeoxynucleotides (ODNs) is widely applied in gene function analyses; however, experiments with ODNs in plants are scarce. In this work, we extend the use of ODNs in different plant species, optimizing the uptake, stability, and efficiency of
