Satellite Symposium 5: Molecular Breeding
Description
Rhodesgrass (Chloris gayana Kunth) has been cultivated as one of the most important warm-season grasses in the world. One of the major limitations for cattle production on forage grasses, especially warm-season grasses is poor digestibility if compared to temperate grasses (Gondo et al., 2003). It is believed that the low digestibility of warm-season grasses is due to high lignin contents (Akashi et al., 2003). Recently, modification of the lignin content of plants appears to be feasible using genetic engineering strategies. We have established a methodology for high-frequency somatic embryogenesis and multiple shoot formation from seed-derived shoot apical meristems in rhodesgrass. Also, we have studied several factors involved in particle bombardment transformation.
