A cDNA clone, Mdh3, was isolated from young fruit of
Malus domestica Borkh. The Mdh3
gene is closely related to the Phalaenopsis 039
homeobox gene, which is involved in ovule development in orchids.
Mdh3 mRNA was expressed in young apple leaves, flower
buds and young fruit. In situ hybridization of flower
buds showed that Mdh3 mRNA accumulated in the ovules,
suggesting that Mdh3 may be involved in apple ovule
development.Keywords: Apple, cDNA clone, fruit,
homeobox gene, ovules.
