Haploid mesophyll protoplasts of Nicotiana plumbaginifolia were mutagenized by UV-irradiation. Protoplast-derived colonies were then selected for valine resistance on a medium containing 5 or 10 mM valine. From the resistant calli, plants were regenerated. Resistance was inherited as a recessive Mendelian character in seven clones. Mutations conferring valine resistance were shown to be allelic. Protoplast-derived cells of L-valine-resistant plants were also resistant to L-threonine. Resistance to valine was based on a reduced valine uptake rate. [ABSTRACT FROM AUTHOR] |
