Abstract

How does your garden grow? Plant shoots are derived from three tissue types — the epidermal, sub-epidermal and inner cell tissue. One of them holds the key to determining the final size of the plant, but the question as to which one has remained controversial for more than a century. Now the targeted expression of brassinosteroid biosynthesis genes in dwarf Arabidopsis plants has provided the answer: it is the epidermis that both drives and restricts shoot growth. Brassinosteroids are plant hormones that are chemically related to cortisol and have a broad spectrum of effects on plant growth.
