Use of dwarfism is one of the most available tasks for breeding program.
Dwarfism arises from various types of defects, but two major factors responsible
for dwarfism, gibberellin (GA) and brassinosteroid (BR), have been most
intensively studied (Sakamoto et al. 2004, Hong et al. 2004). In contrast
to the extensive characterization of dwarf mutants related to GA or BR,
dwarf mutants with phenotypes that differ from the typical GA- or BR-
related phenotypes have not been well characterized (Komorisono et al.
2005). Characterization of these mutants may be useful not only for breeding
programs but also for understanding the mechanisms of stem elongation.
