Figure 5From: Deciphering the genomic structure, function and evolution of carotenogenesis related phytoene synthases in grassesEffect of ABA treatment on wheat PSY expression. (a) Experimental design. (b) Expression level of PSYs in non-stressed leaves and roots. Transcript levels were normalized using the wheat spastin and RNase L inhibitor-like cDNA. (c) (d) (e) Figures show PSY response (y-axis) to ABA treatments at the three different tested concentrations (50 μM in c panel, 100 μM in d panel and 150 μM in e panel) in both leaves and roots (see legend) from 0 to 8 hours (x-axis). cDNA and expressed relative to the level detected in not stressed tissues. Each stage has been compared two by two with a confidence level of 95%. The statistical significance in gene expression is shown by an astrisck (*). (f) Efficiency of ABA on PSY 3 induction in wheat roots.Back to article page
