  • Patent number: 8697445
    Abstract: The present description concerns methods for regeneration of whole plant from the explants obtained from the Abelmoschus species preferably A. esculentus. In addition the present description also concerns methods for transforming okra plant, plant cells and tissues either with the use of recombinant Agrobacterium strain or by bombarding the explants with tungsten or gold particles coated with DNA sequences of interest. An efficient method to isolate embryos from imbibed seeds of okra is also described which enables the use of young meristematic cells of plumule tip for efficient regeneration and transformation of okra plants. Further, transformed okra plants, plant cells and tissues for improved agronomic/non agronomic traits and insect resistance are produced either by using marker based or marker free systems.
    Type: Grant
