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 which show interesting expression patterns. As a result of northern-blot analysis, four genes showed the same expression patterns as cDNA microarray. One of them was a putative farnesylated protein. Others are in progress to obtain the details of their expression profiles by northern-blot analysis.
