Fig. 2From: A global non-invasive methodology for the phenotyping of potato under water deficit conditions using imaging, physiological and molecular toolsConcentration of phytohormone abscisic acid (ABA) and relative expression of selected drought-responsive genes in potato leaves under Control, Mild (MWD) and Severe (SWD) water deficit conditions. a Concentration of ABA in the potato leaves; b relative expression levels of ABA-dependent transcription factors in the potato leaves; c relative expression levels of ABA-independent transcription factors in the potato leaves and d relative expression levels of selected drought-inducible genes in the potato leaves. Bars show means ± SEM of 7 biological replicates. Different letters denote significant differences according to ANOVA followed by a Tukey HSD test (p < 0.05; n = 7)Back to article page
