| Outline of Final Research Achievements |
Strigolactones (SLs) are derived from beta-carotene. Beta-carotene isomerase, carotenoid cleavage dioxygenase (CCD) 7, CCD8, and cytochrome P450 are involved in SL biosynthesis. Plant roots can highly produce SLs in response to phosphorus and/or nitrogen deficiencies. In addition to the nutrient deficiencies, this study demonstrated that sulfur deficiency stimulated SL production in plant roots. The increased SL level is due to marked expression of D27 that encodes b-carotene isomerase.
