Gymnosperm means “naked seed” and comes from the same Greek root as gymnastics, which means to exercise naked. This group of plants is so named because the seeds are not enclosed inside an ovary, ...

Named for Charles Darwin, the only known specimen of a newly discovered beetle, Darwinylus marcosi, died in a sticky gob of tree sap some 105 million years ago in what is now northern Spain. As it ...

Determining the major drivers of species diversification and phenotypic innovation across the Tree of Life is one of the grand challeges in evolutionary biology. Facilitated by the Germplasm Bank of ...

The Sago palm, Cycas revoluta, of course, is not a palm at all, but a gymnosperm, and thus more closely related to pine trees than palms. The botanist in me wants to remind you that gymnosperms are an ...

Plants tend to hoard DNA, not throwing anything out. The extra genes they hold inside can mutate to produce new physical traits. Holding onto the extra genes increases the tempo of evolution for the ...

Proteomics is a powerful technique for examining the structure and function of the proteome. Proteomics can uncover the relationship between DNA, RNA, and the production of proteins -- enabling the ...

Established in the summer of 1997 by Christopher Earle, the Gymnosperm Database is about what you’d expect-a site full of information about conifers and related trees. Navigaton is simple . Users move ...

Gymnosperms, of which there are around 1,026 species 3, are vascular plants, meaning that they contain a tubular tissue network that transports water and nutrients, and provides mechanical support.

This is a preview. Log in through your library . Abstract The role of polyploidy in gymnosperms has been evaluated. Polyploidy is found in the progeny of diploid species, in stray trees of otherwise ...

Evolutionary investigation into the genomes of primitive, non-flowering plants uncovers genes involved in seed development, which may aid scientists in crop improvement and plant conservation.
