Expression profile analysis of early fruit development in iaaM-parthenocarpic tomato plants.

ABSTRACT:

Background

Fruit normally develops from the ovary after pollination and fertilization. However, the ovary can also generate seedless fruit without fertilization by parthenocarpy. Parthenocarpic fruit development has been obtained in tomato (Solanum lycopersicum) by genetic modification using auxin-synthesising gene(s) (DefH9-iaaM; DefH9-RI-iaaM) expressed specifically in the placenta and ovules.

Findings

We have performed a cDNA Amplified Fragment Length Polymorphism (cDNA-AFLP) analysis on pre-anthesis tomato flower buds (0.5 cm long) collected from DefH9-iaaM and DefH9-RI-iaaM parthenocarpic and wild-type plants, with the aim to identify genes involved in very early phases of tomato fruit development. We detected 212 transcripts differentially expressed in auxin-ipersynthe
