The Sensitivity of Mutants of Genes That Regulate Flowering Time to Salt Stress.

(A) and (B) Similar to skb1-1, the skb1-1 flc-3 double mutant is hypersensitive to salt stress, and the sensitivity of flc-3 to salt stress is similar to that of the wild type.

(C) The survival rate of the other mutants of genes that regulate flowering time, including fca, fve, fld4, flk, fy, ld, prmt4a prmt4b, prmt10, and sdg8. Four-day-old seedlings were transferred from MS medium to MS medium with 0, 80, 120, or 160 mM NaCl. Survival rate was determined 30 d after seedling transfer to the treatment medium. Data represent means ± se of three independent experiments (n > 40).

(D) Flowering times of the wild type (Col-0) and the skb1-1 mutant treated on MS medium with 0, 25, 50, or 75 mM NaCl for 5 d before transfer to soil.
