Abstract:
Genetic improvement of rice is crucial to achieve global food security as rice is an important staple crop for more than half of the global population. One of the methodologies for genetic improvement is biolistic delivery of genetic components into plant cells. In this chapter, we describe steps involved in introducing plasmid DNA carrying gene of interest into rice mature embryos using Biolistic® PDS-1000/He particle delivery system. We also provide information required for recovery of transformed plants and production of transgenic seed for next generation analysis. Using this protocol, typical 50-70 putative independent transgenic callus lines can be generated from 100 bombarded embryos. Transgenic rice plantlets can be produced within 2 months after the initiation of seed germination for transformation.

The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
