Fig. 11From: The G2-Like gene family in Populus trichocarpa: identification, evolution and expression profilesExpression patterns of 11 representative PtGLK genes in response to abiotic stresses and phytohormone treatments. The abiotic stresses and phytohormones used here were cold stress, osmotic stress, and MeJA and GA treatments. The relative expression levels were normalized to the reference gene Pt18SBack to article page
