Altered morphologies and ethylene biosynthesis of light-grown Cr-OsACS mutants in Pi-sufficient or -deficient growth conditions. (A, B) Representative images of whole seedling of WT and Cr-OsACS mutants grown in either Pi-sufficient (+P) or -deficient (–P) conditions (A) and the enlarged root images of seedlings (B) in (A). Scale bars=20 mm. (C) Representative images of the enlarged lateral roots of WT and Cr-OsACS mutant seedlings in (A). Scale bars=10 mm. (D) The length of shoots and roots of WT and Cr-OsACS mutant seedlings grown in P-sufficient or -deficient conditions. (E, F) Measurement of the total lateral root length (E) and lateral root number (F) of WT and Cr-OsACS mutants grown in Pi-sufficient or -deficient conditions. (G) Pi deficiency-induced ethylene biosynthesis in the Cr-OsACS mutants. Seedlings were grown in either Pi-sufficient or -deficient media for 7 d and the accumulated ethylene was measured. Error bars indicate the SD; n=3, *P<0.05, **P<0.01, ***P<0.005, Student’s t-test.
