Assessment three constitutive promoters for GUS expression in rice (Oryza sativa L., var. J-104) Evaluación de tres promotores constitutivos para la expresión GUS en arroz (Oryza sativa L., cv. J-104)
2016
This work analyzed the constitutive expression of the s-Glucuronidase (GUS) reporter gene fused to three promoters: the cauliflower mosaic virus (CaMV) 35S, the chimerical A9 promoter which contains rice Act1, and the Ubiquitine-1 promoter from maize. The activity of the promoters was qualitative and quantitatively obtained in different tissues and various growth stages of rice plants (cv J-104) transformed by biolistic. All the promoters were found to be active, with distinct patterns of relative activity in leaves, stem and roots from in vitro and ex vitro plants, and in plants of T1 progeny. The chimerical A9 promoter increased significantly levels of GUS expression in all the tissues and at all growth stages of the plants.
