The newly sequenced genome of the Amborella plant addresses Darwin's "abominable mystery"—the question of why flowers suddenly proliferated on Earth millions of years ago. The genome sequence sheds new light on a major event ...
Pioneering research led by Indiana University has identified genes from a number of plant species, including the entire mitochondrial genomes from three green algae and one moss, in the mitochondrial genome of Amborella trichopoda. ...
RNA, a nucleic acid involved in protein synthesis, is widely used in genetic research to study patterns of gene expression in different organisms. The types and quantities of RNA present in an organism indicate which genes ...
A fossil leaf fragment collected decades ago on a Virginia canal bank has been identified as one of North America's oldest flowering plants, a 115- to 125-million-year-old species new to science. The fossil find, an ancient ...
The dramatic explosion of flowering plant species that occurred about 100 million years ago was thought to have been good news for evolving mammals, providing them with new options for food and habitat. But research by geologists ...
Drilling cores from Switzerland have revealed the oldest known fossils of direct ancestors of flowering plants. These beautifully preserved 240-million-year-old pollen grains are evidence that flowering plants evolved 100 ...
The extraordinary level of conservation of the tulip tree (Liriodendron tulipifera) mitochondrial genome has redefined our interpretation of evolution of the angiosperms (flowering plants), finds research in biomed Central's ...
(Phys.org)—Why are the leaves on the tallest trees all about the same size, and why aren't those tall trees even taller? It all has to do with basic scientific principles at work in nature, according to researchers at Harvard ...
Chinese researchers have solved the mystery of the function of sheaths in flowering orchids. In a paper published in PLOS ONE, the team led by Zhong-Jian Liu at the Orchid Conservation & Research Center of Shenzhen and Laiqiang ...
(Phys.org)—Research by Indiana University paleobotanist David L. Dilcher and colleagues in Europe sheds new light on what Charles Darwin famously called "an abominable mystery": the apparently sudden appearance and rapid ...
