Other claims from this paper (14)
- Observation ALA and Glu labels entered chlorophyll a and carotene.
- Intervention effect Ozone did not inhibit ALA incorporation into chlorophyll a molecules.
- Intervention effect Ozone inhibited chlorophyll a phytol labeling.
- Intervention effect Ozone inhibited carotene labeling.
- Intervention effect Ozone did not inhibit carotene labeling when MVA supplied the label.
- Mechanism Ozone may inhibit plastid isoprenoid biosynthesis from ALA and Glu products.
- Observation The inhibition was more prominent with ALA than with Glu labeling.
- Intervention effect Pheophorbide a significantly increased after incubation with ALA and Glu in ozone-treated pine.
- Intervention effect Phytol labeling decreased after incubation with ALA and Glu in ozone-treated pine.
- Observation ALA produced stronger inhibition of carotene biosynthesis than Glu under ozone.
- Observation ALA produced greater activation of chlorophyll a tetrapyrrole labeling than Glu under ozone.
- Mechanism Ozone was interpreted to inhibit conversion of ALA to Glu during ALA catabolism.
- Mechanism The authors inferred more intensive Glu than ALA metabolism for cytosolic carotene biosynthesis.
- Mechanism The authors inferred cooperation between two isopentenyl diphosphate biosynthetic pathways.
