Cloning, Characterization and Functional Analysis of the LtuPTOX Gene, a Homologue of Arabidopsis thalianaIMMUTANS Derived from Liriodendron tulipifera.

ABSTRACT: Flower colour and colour patterns are crucial traits for ornamental species; thus, a comprehensive understanding of their genetic basis is extremely significant for plant breeders. The tulip tree (Liriodendron tulipifera Linn.) is well known for its flowers, odd leave shape and tree form. However, the genetic basis of its colour inheritance remains unknown. In this study, a putative plastid terminal oxidase gene (LtuPTOX) was identified from L. tulipifera based on multiple databases of differentially expressed genes at various developmental stages. Then, the full-length cDNA of LtuPTOX was derived from tepals and leaves using RACE (rapid amplification of cDNA ends) approaches. Furthermore, gene structure and phylogenetic analyses of PTOX as well as AOXs (alternative oxidases), another high
