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”
e3“MdTCP46 also interacted with a bric-a-brac/tramtrack/broad (BTB) protein, MdBT2, that is responsive to high light intensity, which ubiquitinated MdTCP46 and mediated its degradation via the 26S proteasome pathway”

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 Under high light, MdTCP46 promotes anthocyanin biosynthesis through direct interaction with MdMYB1, which enhances MdMYB1 binding to its target genes.
- 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.
