The third putative transcription factor appears to be a universal regulator of flavonoid-pathway genes, as many pathway transcripts decrease in abundance when this gene is silenced. Another affects LAR and FLAVONOL SYNTHASE (FLS) after overexpression. One increases only LEUCOANTHOCYANIDIN REDUCTASE ( LAR) and FLAVONOL 3’-HYDROXYLASE (F3’H) transcript accumulation upon overexpression. The results suggest that two of the newly-identified regulators likely contribute to discrete nodes of the flavonoid pathway. ![]() Fifteen transcripts corresponded with putative transcription factors, and several of these were examined experimentally using transient expression in developing fruits. The transcriptomes of red, ripe fruit from two parental lines and 14 of their progeny were compared, and uncharacterized transcripts matching the expression patterns of known flavonoid-pathway genes were identified. ![]() New modulators of the strawberry flavonoid pathway were identified through correlation network analysis.
