Molecular phylogenetic reconstructions of Pinaceae based on immunological approaches plus nuclear and organellar DNA sequences consistently resolve the generic pairs Larix – Pseudotsuga and Abies – Keteleeria. In most analyses Pseudolarix and Tsuga (including Nothotsuga) form a clade that is sister to the Abies - Keteleeria clade, and Cathaya, Picea, and Pinus make up an unresolved trichotomy.
The position of Cedrus remains problematic; molecular evidence supports a basal position in the family.
Within Pinaceae genera, molecular phylogenetic reconstructions have markedly improved our understanding of species relationships and biogeography in Pinus, Larix, Pseudotsuga, and Tsuga.
