Brinjal (Solanum melongena L.) is one of the most important vegetable crops in India. In spite of the docility of brinjal towards genetic transformation through Agrobacterium, development of stable transgenic lines in brinjal is a cost, labour as well as time consuming process. On the other hand, the agro infiltration process has been optimized in different crops for the rapid analysis of transgene through transient expression. The process has also gained importance in synthetic biological applications for rapid production of therapeutic biomolecules in plants. Here, we have evaluated the agroinfiltration process in brinjal leaves through transient expression of a reporter gene driven by a constitutive promoter. Following optimization of the incubation period, proper infiltration medium and the optical density of the Agrobacterium suspension, we advocate the usefulness of the process for gene function analysis and other possible downstream applications through transient expression of a transgene in brinjal. | A simple method for transient expression of reporter gene in Brinjal leaves through agroinfiltration
