Application

Epibrassinolide has been used:
  • in Murashige and Skoog (MS) medium to study the cotyledon and shoot length response of Cappelle-Desprez (rht8) and RIL6 (Rht8) plants towards it
  • in callus-inducing medium for callus induction
  • to induce the expression of the gene leaf inclination 2 (LC2) in rice sampling
