Fig. S1. Sequence Alignment of TAR1 and Twenty-three TAR1-related Proteins.
The alignment was used to produce the NJ phylogenetic tree shown in Fig 2A. All
proteins contain a single AP2 domain at their N termini, as shown in box, except three

Fig. S4. Identification of Transgenic A. annua Plants.(A) The reduced transcript level of the TAR1 gene in TAR1-RNAi lines by
semiquantitative RT-PCR. Actin was used as a control for normalization. Each line is
identified with three technical repeats.
(B) qRT-PCR analysis of TAR1 expression in different TAR1-RNAi lines. Actin was
used as a control for normalization. Each data point is the average of three technical
repeats and the results were consistent in three biological replicates. Error bars
indicate SD.
(C) qRT-PCR analysis of TAR1 expression in different TAR1-overexpressing lines.
Actin was used as a control for normalization. Each data point is the average of three
technical repeats and the results were consistent in three biological replicates. Error
bars indicate SD.

qRT–RCR analysis of the GUS gene expression in transiently transformed or
35s:TAR1 stably transgenic A. annua with Agrobacterium harboring DBR2pro:GUS
and 35s:TAR1 or DBR2pro:GUS alone.
The CBF2- and RAA-motif were highlighted by blue or yellow background
respectively. For mutant construction, change “G” to “T” in CBF2 motif and “C” to
