Examples of phenomena involved in this High Irradiance Response (HIR) include: 

• anthocyanin synthesis in seedlings and apple skins

• inhibition of hypocotyl elongation in mustard, lettuce and petunia

• plume hook opening in lettuce

• cotyledon enlargement in lettuce

• ethylene production in sorghum
