Relative expression of the NCED5 gene and ABA content in Medicago truncatula seedlings under water deficit induced by PEG or after ABA treatment. After 46 h of germination (T=0 h), seedlings were incubated with PEG (–0.25 MPa) or with ABA (10 μM) for 72 h. As a control, seedlings were well-watered. (A) NCED5 transcript abundance of treated dark-grown seedlings was plotted as the relative expression (ratio) of the non-stressed control seedlings at the indicated time points. (B) Determination of ABA content in axis during 72 h according the treatments. Means ±SE, n=3.
