An in planta, Agrobacterium-mediated transient gene expression method for inducing gene silencing in rice (Oryza sativa L.) leaves.
2012
Background
Localized introduction and transient expression of T-DNA constructs mediated by agro-infiltration of leaf tissues has been largely used in dicot plants for analyzing the transitivity and the cell-to cell movement of the RNAi signal. In cereals, however, the morphology of the leaf and particularly the structure of the leaf epidermis, prevent infiltration of a bacterial suspension in cells by simple pressure, a method otherwise successful in dicots leaves. This study aimed at establishing a rapid method for the functional analysis of rice genes based on the triggering of RNA interference (RNAi) following Agrobacterium-mediated transient transformation of leaves.
