Figure 6. The expression levels of genes related to strigolactones biosynthesis and signal transduction under different salinities in Spartina alterniflora . (a) SaD10 ; (b)SaD17 ; (c) SaD14 ; (d) SaD53. SaTublin was use as reference gene.
As shown in Figure 6, the expression levels of SaD10 ,SaD17 , SaD14 and SaD53 in 0‰ salinity treatment were totally higher than that in 15‰ and 30‰ salinity treatment. For 15‰ salinity treatment, the expression levels of SaD10 , SaD17and SaD53 were mostly higher than 30‰ salinity treatment (Figure 6a, b, d), except SaD14 , which was lower than 30‰ salinity treatment (Figure 6c). Besides, the expression level of SaD53 in 15‰ salinity treatment were continuously rising (Figure 6d).
