Naked Plants - Buy The Hemato Genome Project.

Recently, by the Chinese Academy of Sciences Xianhu Botanical Garden, the Chinese Academy of Sciences Sino-African Joint Research Center, Wuhan Botanical Garden, Plant Research Institute, the Royal Botanic Garden Qiu Yuan and more than 10 well-known institutions at home and abroad jointly carried out the "Naked Plant - Buy The Whole Genome Project" made important progress. The origin, disagreement and evolution of
bare plants and quilt plants are the basic hot areas of modern plant science.
more than 350,000 seed plants are divided into five categories: siovine, pine cypress, ginkgo, buying hemp vines (naked plants) and flowering plants (quilt plants).
, buying hemp vine plants has been widely concerned by botanists around the world because of their unique morphological characteristics and historical background.
it is understood that the emergence of modern buying of hemlet plants began in the early Cretaceous period, along with the separation of the Guwana land, with present-day Africa (mainly in West Africa) as the origin center, and gradually formed an intercontinental intermittent distribution of species diversity pattern.
more than a century, the scientific community to buy the systematic classification of hemp-vine plants continue to debate the status of different hypotheses, so far still has not been conclusive, known as the "hundred-year battle."
the project team conducted genome-wide sequencing and assembly of G.montanum, which is close to 4.5G, and combined with transcription data to compare and analyze the 17 representative terrestrial plants that have been published today.
study found that the genomic characteristics of buying the vine were significantly different from those of other published seed plant groups (conifer, ginkgo, quilt plants), which were "similar" to the oil-free camphors of the oldest existing quilt plants in terms of inclusions, repeated sequence evolution, and so on.
In addition, buying the vine presents a very ancient state on the conservative set of seed plant functional genes (shared by existing seed plants), suggesting that there has been no drastic family expansion and contraction.
the study, which comprehensively analyzes and presents the unique "characteristics" of buying the vine, helps to push through and discuss the specific genomic characteristics of the common ancestor of seed plants, and also provides new thinking and perspective on the hypothesis that is currently the conifer's sister group,, suggesting that the early evolution of seed plants may be more complex.
research published in Nature-Plant in the form of a cover paper.
