Study of cis-cinnamic acid in Arabidopsis thaliana

Trans-cinnamic acid (CA) can be isomerized to cis-CA in Arabidopsis thaliana extract under sunlight. Piperonylic acid treatment of Arabidopsis under ultraviolet (UV) light increased the level of cis-CA in these treated tissues. Similarly, cis-CA was also detected from Oryza sativa seedlings grown un...

Zusammenfassung:Trans-cinnamic acid (CA) can be isomerized to cis-CA in Arabidopsis thaliana extract under sunlight. Piperonylic acid treatment of Arabidopsis under ultraviolet (UV) light increased the level of cis-CA in these treated tissues. Similarly, cis-CA was also detected from Oryza sativa seedlings grown under sunlight. These results suggest that cis-CA may occur in planta. Application of cis-CA to seedlings of both wild type Arabidopsis and auxin-insensitive mutants, aux1 and axr2, resulted in nearly identical dose response curves in root growth, indicating that the mode of action by which cis-CA affects plant growth is different from that of auxins. According to root growth inhibition assay, cis-CA is nearly 10 times more active than trans-CA. These results suggest that cis-CA is a unique plant growth regulator but its in vivo function remains to be elucidated
