Comment
The dwarf mutant d61 developed not only dm-type (characterized by reduced elongation specifically in the second internode counted from the top) but also dn-type (normal type). This mutant phenotype is caused by loss of function of a rice BRASSINOSTEROID INSENSITIVE 1, OsBRI1 gene. OsBRI1 is similar to Arabidopsis BRI gene (At4g39400), which encodes a putative BR receptor. Functions of OsBRI1 involve in (1) internode elongation by inducing the formation of the intercalary meristem and the longitudinal elongation of internode cells, (2)bending of the lamina joint, and (3)skotomorphogenesis. Several alleles were identified, the weakest allele, d61-7, showed semidwarfism and erect leaves which results in producing biomass more effectively than wildtype at high planting density.
