Phenotypes of spl11, the Spin1 overexpression line, and pub13. A, Cell-death phenotypes of spl11 under SD (10 h of light and 14 h of dark) and LD (14 h of light and 10 h of dark) conditions in growth chambers. B, Flowering phenotype of japonica rice ‘Nipponbare’ Nipponbare and Spin1 overexpression (OX) plants under natural LD conditions (13 h of light and 11 h of dark). C and D, Cell death in pub13 under LD conditions (16 h of light and 8 h of dark) in a growth room. Col-0 (ecotype Columbia) is the wild-type control. Trypan blue staining was used to detect the cell death of Col-0 and pub13 in D. E, Flowering phenotype of pub13 under LD conditions in a growth room. Both Col-0 and pub13 were 32 d old.
