Figure 1. Genetic Analysis of the High Na+ Trait in Shoots of Arabidopsis thaliana Accessions Ts-1 and Tsu-1.

Figure 1

(A) Seven-week-old plants of Col-0, Ts-1, and Tsu-1 accessions grown under short-day conditions.

(B) Na+ levels in the shoot are higher in Ts-1 and Tsu-1. Na+ content in shoots of Cvi-0 (n = 12), Se-0 (n = 12), Van-0 (n = 12), Mt-0 (n = 12), Nd-1 (n = 12), Mrk-0 (n = 12), Col-0 (n = 12), Kas-2 (n = 12), Est-1 (n = 12), Ler-2 (n = 12), Ts-1 (n = 12), and Tsu-1 (n = 8). Presented data are the mean ± SD.

(C) The higher Na+ accumulation in the shoot of Ts-1 and Tsu-1 is a recessive trait. Na+ content in shoots of Col-0 (n = 40), Ts-1 (n = 20), Tsu-1 (n = 20), and F1 plants derived from the crosses Ts-1 × Col-0 (n = 19) and Tsu-1 × Col-0 (n = 13). Presented data are the mean ± SE.

(D) Ts-1 and Tsu-1 are allelic for the loci responsible for the higher Na+ levels in the shoot. Na+ content in shoots of Col-0 (n = 140), Ts-1 (n = 40), Tsu-1 (n = 40), and F1 hybrid plants derived from the cross Tsu-1 × Ts-1 (n = 10).

Presented data are the mean ± SE.
