GENETIC ENGINEERING OF REPRODUCTIVE STERILITY IN PINUS RADIATA
Acta Horticulturae, 1998Generation of transgenic trees for reproductive incompetence is an important application of genetic engineering to commercial forestry. This involves isolation and characterisation of the regulatory regions of the genes expressed at the very early stages of male and female reproductive organ development.

Production of male- and female-sterile plants through reproductive tissue ablation
Journal of Plant Physiology, 2009Male and female sterilities have many useful applications in horticultural crops, including reducing the invasive potential of new ornamentals, elimination of pollen allergens and redirecting resources from seeds to vegetative growth. In this study, we tested a male- and female-sterility (MS; FS) gene construct in Nicotiana tabacum to evaluate its ...
