Molecular evolution of Adh and LEAFY and the phylogenetic utility of their introns in Pyrus (Rosaceae)
Journal: BMC Evolutionary Biology
Year: 2011

Our study represents the first phylogenetic analyses based on LCNGs in Pyrus. Ancient and recent duplications lead to a complex structure of Adh outparalogs and inparalogs in Pyrus and Malus, resulting in neofunctionalization, nonfunctionalization and possible subfunctionalization. Among all investigated orthologs, LFY2int2-N is the best nuclear marker for phylogenetic reconstruction of Pyrus due to suitable sequence divergence and the absence of lineage sorting.
