Mutations in the SAUR Genes Suppress the Premature Cotyledon Opening Phenotype of mTCP4 Plants.

(A) Photographs showing cotyledons of 4-d-old dark-grown seedlings of Col, mTCP4, saur50/mTCP4 (s50/mTCP4), saur16 saur50/mTCP4 (s16 s50/mTCP4), saur16 saur50 saur77 saur78/mTCP4 (s16 s50 s77 s78/mTCP4), and saur16 saur50 saur62 saur77 saur78/mTCP4 (s16 s50 s62 s77 s78/mTCP4).

(B) Cotyledon opening percentages of the indicated lines, showing the reduced occurrence of premature cotyledon opening in the dark when multiple indicated SAUR genes were mutated.

(C) Cotyledon opening angles of the indicated lines, showing the reduced severity of the phenotype caused by multiple SAUR gene mutations in mTCP4.

Data are shown as the mean ± se. Statistical significance was calculated using two-tailed Student’s t test against mTCP4: **, P < 0.01; ***, P < 0.001.
