Herbicide Resistance in Datura innoxia: Cross-Resistance of Sulfonylurea-Resistant Cell Lines to Imidazolinones.
Cells resistant to the sulfonylurea herbicides chlorsulfuron and sulfometuron methyl were isolated from a predominantly haploid cell suspension culture of Datura innoxia P. Mill. Exponentially growing cell colonies (aggregates of about 40 cells) were mutagenized with ethyl methane sulfonate, subcultured for 10 days to allow growth recovery and plated on a medium containing either chlorsulfuron ...
متن کاملExpression of 5-Methyltryptophan Resistance in Plants Regenerated from Resistant Cell Lines of Datura innoxia.
Seventy-nine 5-methyltryptophan-resistant cell lines have been selected from haploid Datura innoxia Mill. cell cultures by plating suspensions in agar medium containing a growth inhibitory concentration of 5-methyltryptophan. Mutagen treatment increased the frequency of resistance. The eleven variants tested posses an altered anthranilate synthase less sensitive to feedback inhibition by trypto...
متن کاملMethotrexate Resistance in Datura innoxia (Uptake and Metabolism of Methotrexate in Wild-Type and Resistant Cell Lines).
A wild-type Datura innoxia cell line (Px4) was used to select methotrexate-resistant cells through a stepwise procedure. Two independently selected cell lines, MTX161 and MTX132, were stable and shown to be 5 to 15 times more resistant to methotrexate than wild type. These methotrexate-resistant cells were similar to the wild-type cells in levels and kinetic properties of dihydrofolate reductas...

متن کاملA Nitrate Reductase-less Variant Isolated from Suspension Cultures of Datura innoxia (Mill.).
A comparative study has been carried out of the growth of two lines of Datura innoxia (Mill.) cells, designated DI-6 and NR1, their resistance to chlorate, and their ability to assimilate nitrate in sterile culture. The NR1 cell line was isolated from DI-6 cultures by first growing the latter in a nitrate-based medium for 5 days and then transferring the cells to a medium containing 2 grams lit...
