The AINTEGUMENTA genes MdANT1 and MdANT2 are associated with the regulation of cell production during fruit growth in apple (Malus × domestica Borkh.)

摘要

BackgroundFruit growth in apple (Malus × domestica Borkh.) is mediated by cell production and expansion. Genes involved in regulating these processes and thereby fruit growth, are not well characterized. We hypothesized that the apple homolog(s) of AINTEGUMENTA (ANT), an APETALA2–repeat containing transcription factor, regulates cell production during fruit growth in apple.
