Fluoroorotic acid-selected Nicotiana plumbaginifolia cell lines with a stable thymine starvation phenotype have lost the thymine-regulated transcriptional program.

Plant physiology - 1 Aug 2000

Santoso D, Thornburg R

Abstract excerpt

We have selected 143 independent Nicotiana plumbaginifolia cell lines that survive in the presence of 5-fluoroorotic acid. These lines show several diverse phenotypes. The majority of these cell lines showed reduced levels of UMP synthase. However, one particular phenotype, which represents 14% of the total independent lines (20 cell lines), showed an unexpected, high level of UMP synthase and was therefore...
