Defined Mutants in Higher Plants
This chapter briefly reviews work on mutant selection using somatic cells of higher plants and then describes experiments designed to recover agriculturally useful variants. Mutants of Nicotiana tabacum were recovered which were resistant to an analog of methionine. These plants were found to be much less susceptible to damage by the pathogen Pseudomonas tabaci, which produces a toxin that is an analog of methionine. Several mutants show a specific increase in the level of free methionine.
