On the cover: Chimeric repressors are generated by attaching a short transcriptional repressor domain to transcription factors, and have been widely used as effective tools for modifying floral traits in plants. However, expression of these chimeric repressors can sometimes cause other undesirable morphological changes. Sasaki et al. generated five constructs using floral organ-specific promoters from Arabidopsis thaliana and Torenia fournieri to drive expression of the chimeric repressor of Arabidopsis TCP3 (AtTCP3). They found that different combinations of the one Arabidopsis and four Torenia floral organ-specific promoters driving the chimeric AtTCP3 repressor caused distinct changes in the color, color patterns, and cell-shapes of petals, whilst avoiding other unfavorable phenotypes. Thus by using this novel molecular approach, diverse floral traits can be generated.
