Modulation of biosynthesis of photosynthetic pigments and light-harvesting complex in wild-type and gun5 mutant of Arabidopsis thaliana during impaired chloroplast development.

Abstract excerpt

Plants in response to different environmental cues need to modulate the expression of nuclear and chloroplast genomes that are in constant communication. To understand the signals that are responsible for inter-organellar communication, levulinic acid (LA), an inhibitor of 5-aminolevulinic acid dehydratase, was used to suppress the synthesis of pyrrole-derived tetrapyrroles chlorophylls. Although, it does not...
