Comparisons of the blue light-induced hypocotyl inhibition and cotyledon opening for Arabidopsis seedlings of different genotypes. (A) Fluence-rate response of hypocotyl inhibition of ws wild-type (ws), and homozygous lines of transgenic plants overexpressing CRY1 (CRY1+) or CRY2 (CRY2+). (B and C) Fluence-rate response of hypocotyl inhibition (B) and cotyledon opening (C) of Columbia wild-type (Col), cry2–1 mutant (CRY2−), and hy4 mutant (CRY1−).
