The fossil record of flowers is limited, necessitating other approaches to understanding floral evolution. Here, Sauquet and colleagues reconstruct the characteristics and diversification of ...

Yet, how angiosperms pack their leaves with smaller, more abundant stomata and more veins is unknown but linked — we show — to simple biophysical constraints on cell size.

These angiosperms became the first medicines of humans but their variety and beauty also gave them significance for rituals, beautification and to express feelings from sadness to joy.

Here we discuss recent advances surrounding the origin of angiosperms. Putatively primitive characters are now much better understood because of a vastly improved understanding of angiosperm ...

DNA sequences of five mitochondrial, plastid, and nuclear genes from 105 species (103 genera and 63 families) representing all major lineages of gymnosperms and basal angiosperms were analyzed using ...

Fossils of angiosperms first appear in the fossil record about 140 million years ago. Based on the material in which these fossils are deposited, early angiosperms must have been weedy, fast ...

Preserved embryos illustrate seed dormancy in early angiosperms Study illustrates key differences from modern flowering plants Date: December 16, 2015 Source: Yale School of Forestry ...

A tiny flower pressed between layers of sandstone for more than 160 million years could be the earliest angiosperm fossil ever found.

Results of the study, titled "Dosage Sensitivity Shapes Balanced Expression and Gene Longevity of Homoeologs after Whole-Genome Duplications in Angiosperms," were published in The Plant Cell.
