Transcriptional activation of the orphan gene QQS by a MYB-NAC-GARP triad modulates starch and protein accumulation in Arabidopsis.
The Arabidopsis-specific orphan gene Qua-Quine Starch (QQS) regulates starch and protein accumulation, yet the upstream mechanisms controlling its transcription remain poorly understood. Here, we investigated transcription regulators that modulate QQS expression and associated metabolic traits. Using yeast one-hybrid s...
