Figure 8: ATSIG5 acts downstream of ATHB17.

(A) The phenotypes of ATHB17 OX, ATHB17 OX/sig5-1, sig5-1 and WT seedlings grown on MS medium containing indicated concentrations of NaCl. Seeds were sowed on MS medium containing 0, 100, 125, 150 and 175 mM NaCl and grown vertically for 10 days. Bar = 1 cm. (B) root length of the 10-day-old plants grown on MS medium containing different concentrations of NaCl. Values are mean ± SD (n = 45, *P < 0.05, **P < 0.01, ***P < 0.001).
