The response of <i>A</i>. <i>thaliana</i> plants constitutively expressing <i>MsMYB4</i> to the presence of exogenously supplied ABA.

(A)-(C) The germination rate of seeds in the presence of (A) 0 μM, (B) 1 μM, (C) 2 μM ABA. (D)-(F) the effect of the ABA treatment on materials exposed for ten days to (D) 0 μM, (E) 1 μM, (F) 2 μM ABA. (G) quantification of the germination rate of the materials illustrated in (A-C). (H) quantification of the root length of the seedlings illustrated in (D-F). (D-F). VC: transgenic A. thaliana carrying an empty vector, OE3 and OE6: transgenic A. thaliana lines constitutively expressing MsMYB4. Bar: 2 cm. Means derived from the measurement of ten seedlings; *, **: means differed significantly at, respectively, P <0.05 and <0.01.
