Description
TAMARA lines
A population of 9471 stable activation-tagged lines was generated by transposable element mediated activation tagging mutagenesis in Arabidopsis (TAMARA) using the maize En/Spm transposon system. Based on DNA gel blot and flanking sequence analysis, this population contains approximately 6000 independent transposon insertions. A greenhouse-based screen identified six dominant or semi-dominant activation tagged mutants with obvious developmental alterations, among these a new pistillata mutant allele. In addition, a subset of 1500 lines was screened by a HPLC based high-throughput method for dominant activation tagged mutants with enhanced contents of phenolic compounds. One dominant activation tagged mutant (hpc1-1D) was isolated showing accumulation of a particular compound due to the upregulation of an R2R3-MYB transcription factor.
