General Information

General Information Comment Organism
malfunction the redox status of the plastoquinone pool in knockout mutant ics1 shows significant variation depending on the leaf age. Mutant plants treated with a phylloquinone precursor display symptoms of phenotypic reversion towards the wild type. The ics1 mutant also shows altered thylakoid structure with an increased number of stacked thylakoids per granum Arabidopsis thaliana
physiological function the enzyme is required for the appropriate hypersensitive disease defence response. It also takes part in the synthesis of phylloquinone, which is incorporated into photosystem I and is an important component of photosynthetic electron transport in plants role of ICS1 in regulation of state transition. Role of ICS1 in integration of the chloroplast ultrastructure, the redox status of the plastoquinone pool, and organization of the photosystems, which all are important for optimal immune defence and light acclimatory responses Arabidopsis thaliana
