Abstract

Objective: Assess transient gene expression of GUS in cassava (Manihot esculenta Crantz) leaves using Agrobacterium tumefaciens infiltration. Materials and methods: A. tumefaciens strains GV3101 and AGL1 containing pCAMBIA1305.2 were used to evaluate transient gene expression of β-glucuronidase (GUS). A. tumefaciens infiltration (agroinfiltration) was made using both leaves from in vitro and 1 month old greenhouse plants. Leaves were incubated in X-GLUC buffer, stained and photographed to detect GUS activity. Results: Agroinfiltration assays showed GUS transient expression in leaves of cassava varieties widely cultivated in the north coast and eastern savannah, MCOL2215 (Venezuelan) and CM6438-14 (Vergara), respectively. A. tumefaciens agressive strain AGL1 showed high efficiency inducing GUS expression in cassava leaves. Conclusions: We recommend using A. tumefaciens agressive strain AGL1 for agroinfiltration to assess transient expression in cassava leaves.
