Transcriptome Profile Analysis Reveals the Regulation Mechanism of Stamen Abortion in Handeliodendron bodinieri(Levl.)Rehd

To elucidate the molecular mechanism of stamen abortion underlying sex differentiation from transcriptomic aspects in Handeliodendron bodinieri, we use abnormal stamens before and after abortion in female flowers and normal stamen in male flowers at the same stage as control material. Key genes regulating stamen abortion was identified by using RNA-seq technique. The results show that it was abortion science stage 6 during anther development, at the same time, HbGPAT, HbAMS, HbLAP5, HbLAP3 and HbTES were down-regulated , and HbML5 was up-regulated. Therefore, these information will provide theoretical foundation for the conservation, breeding, scientific research and application of Handeliodendron bodinieri. Overall design: Flower buds and anthers mRNA profiles of male and female flowers in Handeliodendron bodinieri(Levl.)Rehd
