Inactivation of SAUR41 subfamily genes leads to reduced cell expansion. (A) Seven-day-old light-grown seedlings of the wild type, the saur41 quadruple mutants saur41/40/71/72 and the SAUR41 overexpression lines OE-SAUR41. (B) Statistical comparison of cotyledon areas in 7-day-old seedlings of three genotypes. (C) Statistical comparison of hypocotyl length in 7-day-old seedlings. (D) Statistical comparison of root length in 7-day-old seedlings. (E) Statistical comparison of epidermal cell and cortical cell length in 7-day-old hypocotyls. The quadruple mutants saur41-1sauir40-1saur71-1saur72-1 and saur41-5sauir40-1saur71-2saur72-1 are abbreviated as saur41/40/71/72#1 and saur41/40/71/72#4, while the 35S::SAUR41-MYC overexpression lines are abbreviated as OE-SAUR41#1 and #2. Each treatment contained approx. 30 seedlings or cells and was replicated three times. Error bars represent the s.d. **P < 0.01, *P < 0.05, Student’s t-test.
