GENETIC-TRANSFORMATION WITH THE SULL GENE - A HIGHLY EFFICIENT SELECTABLE MARKER FOR SOLANUM-TUBEROSUM L-CV RUSSET BURBANK

Selection of transformed plants is a fundamental requirement for plant molecular breeding. We have developed the use of the sulI gene, whose application has already been described in tobacco [17] for selection in the important potato cultivar Russet Burbank. We found that the Sul I marker is highly effective, with efficiency comparable to that of np tlI. Analysis of the effect of the sulI gene on folate metabolism in R usset Burbank under sulfa drug selection demonstrates that sulI may be an important tool for analysis of folate metabolism in plants.
