Development of transgenic okra (Abelmoschus esculentus L. Moench) lines having RNA mediated resistance to Yellow vein mosaic virus (Geminiviridae).

Begomovirus Yellow vein mosaic virus causes severe yield losses in okra and even the resistant lines developed through conventional breeding show susceptibility at various levels. This paper describes the development of YVMV resistant lines through RNAi strategy. A universal ihpRNA construct harbouring βC1 ORF from the β-satellite of the begomovirus was designed using pRNAi-LIC plasmid.
