Chloroplast phylogenomics indicates that Ginkgo biloba is sister to cycads.
Wu CS, Chaw SM, Huang YY. Wu CS, et al. Genome Biol Evol. 2013;5(1):243-54. doi: 10.1093/gbe/evt001. Genome Biol Evol. 2013. PMID: 23315384 Free PMC article.
In addition, the placement of ginkgo varied in the trees inferred from nucleotide (NU) sequences, which notably depended on breadth of taxon sampling, tree-building methods, codon positions, positions of Gnetopsida (common name: gnetophytes), and including or excluding gne …

Angiosperm origin and early stages of seed plant evolution deduced from rRNA sequence comparisons.
Troitsky AV, Melekhovets YuF, Rakhimova GM, Bobrova VK, Valiejo-Roman KM, Antonov AS. Troitsky AV, et al. J Mol Evol. 1991 Mar;32(3):253-61. doi: 10.1007/BF02342748. J Mol Evol. 1991. PMID: 1904502
Genealogical relationships among gymnosperm taxa cannot be deduced unambiguously on the basis of rRNA data. The only inference may be that the taxon Gnetopsida is an artificial one, and Gnetum and Ephedra belong to quite different lineages of gymnosperms. ...

Morphology and affinities of an Early Cretaceous Ephedra (Ephedraceae) from China.
Yang Y, Geng BY, Dilcher DL, Chen ZD, Lott TA. Yang Y, et al. Am J Bot. 2005 Feb;92(2):231-41. doi: 10.3732/ajb.92.2.231. Am J Bot. 2005. PMID: 21652400 Free article.
Detailed investigations on Lower Cretaceous Ephedra L. fossils (Gnetopsida) reveal morphological characters similar to those of extant Ephedra rhytidosperma Pachomova, including articulate branches with many fine longitudinal striations, a dichasial branching pattern, uni- …

The deep phylogeny of land plants inferred from a full analysis of nucleotide base changes in terms of mutation and selection.
Kawai Y, Otsuka J. Kawai Y, et al. J Mol Evol. 2004 Apr;58(4):479-89. doi: 10.1007/s00239-003-2570-y. J Mol Evol. 2004. PMID: 15114426
The other bryophytes such as Bryopsida, Anthocerotopsida, and Jungermanniidae are sister groups to tracheophytes, the divergence of bryophytes and tracheophytes being estimated to have occurred 483 Mya. The evolutionary distance of Gnetopsida from Coniferopsida and Magnoli …

[Application of the serological method for evaluation of relations between gymnosperms and dicotyledonous plants].
Semikhov VF, Aref'eva LP, Zolkin SIu, Novozhilova OA, Kostrikin DS. Semikhov VF, et al. Izv Akad Nauk Ser Biol. 2002 Sep-Oct;(5):541-51. Izv Akad Nauk Ser Biol. 2002. PMID: 12400377 Russian.
For this purpose, 12 antisera were raised to proteins of taxa representing four gymnosperm classes: Ginkgoopsida, Cycadopsida, Coniferopsida, and Gnetopsida. Seed proteins of eight dicotyledonous subclasses (after Takhtadzhyan, 1987) were used. ...
