Epigenetic instability and trans-silencing interactions associated with an SPT::Ac T-DNA locus in tobacco.

Genetics - 1 Jan 1998

English J J, Jones J D

Abstract excerpt

Progeny of tobacco line 2853.6, which carries a streptomycin phosphotransferase (SPT) gene interrupted by the maize element Activator (Ac), were selected for streptomycin resistance (Spr) because of germinal Ac excision. Some events gave rise to Spr alleles that were unstable and exhibited a mottled phenotype on streptomycin-containing medium due to somatic loss of SPT function. This instability was most...
