Not a few plant growth regulators including plant hormones participate in the regulation of plant growth, and some of them interact each other. Gibberellins (GAs) are well known to promote shoot elongation and recently brassinolide (BL) were also shown to play an important role in shoot elongation of dicotyledonous plants. To see whether BL is involved in the regulation of shoot elongation of rice, we tried to identify the genes responsive to GA and/or BL by cDNA microarray, and obtained some genes categorized into two groups depending on their expression patterns. One is up-regulated by GA+BL-treatment, and the other down-regulated by GA- or BL-treatment. Northern-blot analysis is in progress to obtain the details of their expressions.
