Strigolactones (SLs) are methylbutenolide molecules derived from β-carotene through an intermediate carlactonoic acid (CLA). Canonical SLs act as signals to microbes and plants, whereas noncanonical primarily plant hormones. The cytochrome P450 CYP722C catalyzes a critical step, converting CLA canonical in most angiosperms. Using synthetic biology, we investigated the function of CYP722A , evolutionary predecessor . converts into 16-hydroxy-CLA (16-OH-CLA), SL detected exclusively shoots...
Abstract Many root parasitic plants in the Orobanchaceae use host-derived strigolactones (SLs) as germination cues. This adaptation facilitates attachment to a host and is particularly important for success of obligate weeds that cause substantial crop losses globally. Parasite seeds sense SLs through ‘divergent’ KARRIKIN INSENSITIVE2 (KAI2d)/HYPOSENSITIVE TO LIGHT α/β-hydrolases have undergone duplication diversification genomes. After germination, chemotropic growth parasite roots toward...
