Cedrene

Cedrene regulates auxin transport and signal transduction in Arabidopsis, and thus stimulates the plants root development. Cedrene affects the Arabidopsis roots morphology by increasing the lateral roots, promoting the elongation of primary roots, affecting the expression of the auxin response gene DR5 and auxin transporters such as PIN2 and PIN3[1].
