Verbatim
e0“anthocyanin biosynthesis induced by different light intensities in apple (Malus domestica) was found to be largely dependent on the functions of the MdMYB1 and MdTCP46 transcription factors”
e2“under these conditions it promoted anthocyanin biosynthesis by direct interactions with MdMYB1 that enhanced the binding of the latter to its target genes”

Other claims from this paper (5)
- Mechanism Anthocyanin biosynthesis induced by different light intensities in apple largely depends on MdMYB1 and MdTCP46.
- Observation MdTCP46 expression in apple is responsive to high light intensity.
- Mechanism MdBT2 ubiquitinates MdTCP46 and mediates its degradation via the 26S proteasome pathway.
- Observation MdBT2 expression in apple is responsive to high light intensity.
- Mechanism The MdBT2-MdTCP46-MdMYB1 module plays a key role in modulating anthocyanin biosynthesis at different light intensities in apple.
