Research Abstract

Brassinosteroid (BR) is an essential steroid hormone for plant growth. Since exogenous applications of BR show an increased yield in crops, BR is thought to play an important role in reproductive organs of plants. However, little is known about its molecular mechanism in the reproductive growth. In this study, I tried to clarify the role of BR in fruit productions and also investigated how BR biosynthesis enzymes have been evolved in plants.
