Flowering Plants Evolved 100 Million Years Earlier Than Believed
2013-10-02 07:55:56

[ 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...

A new technique for panoramic, very-high-resolution, time-lapse photography for plant and ecosystem research Ever wonder what plants do when you're not around? How about an entire forest or grassland? Not even the most dedicated plant researcher can be continuously present to track environmental effects on plant behavior, and so numerous tools have been developed to measure and quantify these effects. Time-lapse photography has been used to study many aspects of plant behavior, but...

Special microscope used to reveal hidden aspects of plant anatomy Why don't trees "bleed" to death when they are injured? Researchers from Virginia Tech, the Georg-August University of Gottingen, Germany, and the Jackson Laboratory of Bar Harbor, Maine, have discovered how "check valves" in wood cells control sap flow and protect trees when they are injured. The study, featured on the cover of the September issue of the American Journal of Botany, used a special microscope to reveal...

Microbial organisms associated with plant roots have far-flung global influences, from plant genetics to ecosystem health We often ignore what we cannot see, and yet organisms below the soil's surface play a vital role in plant functions and ecosystem well-being. These microbes can influence a plant's genetic structure, its health, and its interactions with other plants. A new series of articles in a Special Section in the American Journal of Botany on Rhizosphere Interactions: The Root...

Ancient Ancestor Of Tulip Tree Line Identified
2013-09-12 12:42:34

Indiana University The modern-day tulip tree, state tree of Indiana as well as Kentucky and Tennessee, can trace its lineage back to the time of the dinosaurs, according to newly published research by an Indiana University paleobotanist and a Russian botanist. The tulip tree, Liriodendron tulipfera, has been considered part of the magnolia family. But David Dilcher of Indiana University Bloomington and Mikhail S. Romanov of the N.V. Tsitsin Main Botanical Garden in Moscow show that it...

New System For Early Detection Of Plant Spread In Bodies Of Water
2013-08-01 10:23:09

Technical University Munich As a result of climate change, certain undesirable aquatic plants are starting to invade German water bodies. Even popular recreation areas like Lake Starnberg have been affected, leading to a growing need to monitor the spread of these plants. Up to now, regular monitoring has proven to be a costly process. But in a new approach, researchers at Technische Universitat Munchen (TUM) have developed a quicker and less expensive method. Taking a dip in a...

In recent years, major companies from all over the globe, including Exxon Mobile and Itochu Corporation, have merged with research facilities to research algae as a renewable energy source; however, it has been determined that far more research is needed before movement to the commercial production phase of algae biofuel can truly take place. A recent research study published in Phycologia took up this challenge and examined a promising freshwater algal strain for possible genetic...

Plants Resort To Math In Order To Survive Without Sunlight
2013-06-24 10:12:34

Brett Smith for redOrbit.com - Your Universe Online At night, plants must utilize nutrient reserves efficiently until dawn and new research from the John Innes Centre in England has found that some plants use basic math to survive without sunlight for photosynthesis. The British scientists said they were surprised to discover that Arabidopsis uses two different kinds of internal molecules to determine a rate for breaking down starch reserves. "This is the first concrete example in...

Rice Blast Research A Step Closer To Controlling Devastating Crop Diseases
2013-06-18 11:57:00

University of Exeter Like a stealthy enemy, blast disease invades rice crops around the world, killing plants and cutting production of one of the most important global food sources. Now a study by an international team of researchers has shed light on how the rice blast fungus, Magnaporthe oryzae, invades plant tissue. The finding is a step towards learning how to control the disease, which by some estimates destroys enough rice to feed 60 million people annually. The team, from the...

Dawsonia
2013-11-04 10:01:23

Dawsonia is a classification of mosses. This genus is a member of the Polytrichaceae family. Dawsonia plants are commonly known to grow taller and have thicker leaves than other common mosses. Mosses are known to grow when hydrated, however most common mosses lack cuticles and internal transport tissues. This makes it difficult for them to maintain substantial amounts of water and they typically do not grow tall. Dawsonia are an exception to this common rule. Dawsonia mosses are...

Petrified Forest National Park
2013-04-24 16:53:26

Petrified Forest National Park is located in the state of Arizona in the United States. The park holds 221,552 acres of land, of which 50,260 acres are comprised of a designated wilderness. The area was once inhabited by Native American tribes including the basket maker and pueblo peoples. The first American explorers to enter the area arrived while searching for good routes leading from east to west. This group, led by Army Lieutenant Amiel Whipple, surveyed the northern area of the...

The Whisk Fern (Psilotum nudum), is a genus of fern-like vascular plants, one of two genera in the family Psilotaceae, order Psilotales, and class Psilotopsida (the other being Tmesipteris). The distribution of Psilotum is tropical and subtropical, in the New World, Asia, and the Pacific. The highest latitudes known are in South Carolina and southern Japan for P. nudum. In the U.S., one species is found from Florida to Texas, the other in Hawaii. They had traditionally been thought not to...
