Cell Culture, Somatic Embryogenesis and Plant Regeneration in Maize, Rice, Sorghum and Millets

Abstract: The importance of the cereal grains as a worldwide source of human and livestock feed has been a major impetus for the use of plant breeding and husbandry to improve their productivity. Productivity has continued to improve, but at increasing costs (16). Cell and molecular biology offer possible avenues for plant improvement, especially when used in conjunction with conventional breeding. The inadequacy of monocot cell culture technology has been a serious shortcoming in learning more about the biological nature of economically important traits such as disease resistance, stress tolerance and yield. These shortcomings have been most limiting for in vitro selection and genetic transformation where the end product is a regenerated plant from callus or cell cultures. Recovery of plants from cell cultures of monocots has been difficult, especially in germplasm suited for rapid incorporation into breeding populations.
