Enhancement of the Brassinosteroid Biosynthesis Pathway Improves Grain Yield in Rice
Many of the semi-dwarf but high-yielding crop varieties that were developed during Green Revolution are defective in gibberellin biosynthesis or unresponsive to gibberellin (Peng et al., 1999). Of the other kinds of plant hormones, brassinosteroids (BRs) seem to be among the most useful for controlling crop productivity –BR mutants can also be dwarfs and over-expression lines can be high yielding (Choe et al., 2001; Mori et al., 2002; Sakamoto et al., 2006).
