The rise and diversification of bi- and tricellular pollen in flowering plants With the bursting of spring, pollen is in the air. Most of the pollen that is likely tickling your nose and making your eyes water is being dispersed in a sexually immature state consisting of only two cells (a body cell and a reproductive cell) and is not yet fertile. While the majority of angiosperm species disperse their pollen in this early, bicellular, stage of sexual maturity, about 30% of flowering plants...

Genome Sequence Insight Evolution Flowering Plants

redOrbit Staff & Wire Reports - Your Universe Online The newly-sequenced genome of the Amborella plant is shedding new light on the origin of the more than 300,000 flowering plants on the Earth today, including all major food crop species. Amborella trichopoda, a small understory tree found only on the main island of New Caledonia in the South Pacific, is unique as the sole survivor of an ancient evolutionary lineage that traces back to the last common ancestor of all flowering...

America’s Oldest Flowering Fossil Unearths Dark Civil War Past

Lee Rannals for redOrbit.com - Your Universe Online A reclassified ancient fossil has not only been named one of North America’s oldest flower plants, but it is also unearthing some of America’s darkest tales. In 1864, during the Civil War Union Army troops forced a group of freed slaves into involuntary labor. The soldiers forced the freed slaves to dig up a canal along the James River at Dutch Gap, Virginia. While digging the canal, the men exposed the ancient fossil with their...

Mammal Diversity Faltered When Flowering Plants Arrived

Brett Smith for redOrbit.com - Your Universe Online As mammals were trying to emerge from the shadows of dinosaurs 100 million years ago, there was a dramatic proliferation of flowering plant species. However, instead of early mammals benefiting from new food and shelter opportunities that would have been provided by the plants, they experienced a decline during the mid-Cretaceous. Using a morphological analysis, two researchers were able to provide these new insights about mammalian...

Flowering Plants Evolved 100 Million Years Earlier Than Believed

[ Watch the Video: Flowering Plants Arose In The Early Triassic ] redOrbit Staff & Wire Reports - Your Universe Online Researchers from the University of Zurich in Switzerland have uncovered evidence suggesting flowering plants evolved 100 million years earlier than previously believed, according to new research appearing in the open-access journal Frontiers in Plant Science. Flowering plants evolved from extinct plants related to conifers, cycads, ginkgos and seed ferns, and the...

Compromises between quantity and quality are common in animals, but do the same tradeoffs hold true for plants and their flowers? Most creatures face compromises when they reproduce – the more energy they devote to having lots of babies, the less they can invest in each one. But do the same tradeoffs hold true for plants? Biologists have long assumed that plants with bigger, showier flowers can make fewer of them per plant. But the data don't always hold up, scientists say. A new...

The evolution and diversification of the more than 300,000 living species of flowering plants may have been "jump started" much earlier than previously calculated, a new study indicates. According to Claude dePamphilis, a professor of biology at Penn State University and the lead author of the study, which includes scientists at six universities, two major upheavals in the plant genome occurred hundreds of millions of years ago -- nearly 200 million years earlier than the events that other...

An international research team led by Brown University has amassed the largest evolutionary tree (phylogeny) for plants. It has learned that major groups of plants tinker with their design and performance before rapidly spinning off new species. The finding upends long-held thinking that plants' speciation rates are tied to the first development of a new physical trait or mechanism. Results are published in the American Journal of Botany. Just as a company creates new, better versions of a...

Most flowering plants, equipped with both male and female sex organs, can fertilize themselves and procreate without the aid of a mate. But this may only present a short-term adaptive benefit, according to a team of researchers led by two University of Illinois at Chicago biologists, who report that long-term evolutionary survival of a species favors flowers that welcome pollen from another plant. "We've shown that a strong, short-term advantage experienced by individuals that have sex with...

The world is a cooler, wetter place because of flowering plants, according to new climate simulation results published in the journal Proceedings of the Royal Society B. The effect is especially pronounced in the Amazon basin, where replacing flowering plants with non"“flowering varieties would result in an 80 percent decrease in the area covered by ever"“wet rainforest. The simulations demonstrate the importance of flowering"“plant physiology to climate regulation in...

Waterlilies (Nymphaeaceae) belong to the Order Nymphaeales. They are tuberous plants that are rooted in soil in bodies of water, with leaves and flowers floating on the water surface. The leaves are round, with a radial notch in Nymphaea and Nuphar, but fully circular in Victoria. Modern genetic tests of the flowering plants by the Angiosperm Phylogeny Group have shown that the water-lilies are among the most primitive of the flowering plants. The white water-lily is the national flower...
