Figure 1.

Response of Athub2 mutants to osmotic stress. (a) Seeds of the indicated genotypes were germinated on 1/2 MS medium or 1/2 MS previously infused with 25% PEG. Photographs were taken 7 days after germination. Black arrows indicate un‐germinated seeds. (b) Percentages of seeds that germinated in different concentrations of PEG. (c) Root growth of the indicated genotypes. Six‐day‐old seedlings were transferred from 1/2 MS to 1/2 MS medium previously infused with different concentrations of PEG. Photographs were taken 4 and 7 days after transfer, bar = 0.5 cm. (d) Quantification of relative root length in (c). Vertical bars represented standard deviation (SD). (n ≥ 30, *P < 0.05; ***P < 0.001).
