However, several studies have shown that yield is
reduced when plants are shortened too much with dwarfing genes
or plant growth regulators (Guoping et al., 2001; Acreche and Slafer,
2011). Because a reduction in plant height to improve lodging resistance
may reduce the photosynthetic capacity of a canopy, another
target is needed for further improvement in lodging resistance. The
basal part of the culm internode plays an important role in lodging
resistance as it provides a lever to hold the plant upright. Improving
the physical strength of the basal part of the culm internode
