This study aimed to investigate the aquaporin expression of 'Horozkarası’ grapevine. Therefore, own-rooted cv. 'Horozkarası’ grapevines were exposed to two different irrigation treatments; well-irrigated and water-stress treatments under controlled environmental conditions in pots for six days. And then in the stressed plants lipid peroxidation (MDA), relative water content (RWC) and membrane permeability (MP) were measured in leaves. The expression patterns of different PIPs group of aquaporins (PIP2-1, PIP2-2) also were performed with root and leaf tissues. While significant decreases were observed in relative water content (RWC) and membrane permeability (MP) in stress treatment, increase was observed in lipid peroxidation (MDA) in leaves. Also, while significant decreases were observed in PIP2-1 and PIP2-2 in stress treatment in leaves, increases were observed in expressions of PIP2-1 and PIP2-2 genes in drought treatment in root.
