To Charles Darwin it was an 'abominable mystery' and it is a question which has continued to vex evolutionists to this day: when did flowering plants evolve and how did they come to dominate plant life on earth? Today a study in Ecology Letters reveals the evolutionary trigger which led to early flowering plants gaining a major competitive ...

Archives Miscellaneous New Species of Orchid is World's Smallest Topic Categories: Biology Evolution Speciation Posted on: November 30, 2009 9:27 AM, by "GrrlScientist" A close-up of the world's smallest orchid, at just over 2mm from petal tip to petal tip.

Geophysicist G. Clark Davenport runs ground-penetrating radar at NecroSearch's experimental pig burial ground at the Highlands Ranch Law Enforcement Training Facility.

The newly discovered orchid is from the Platystele genus and the petals are so thin that they are just one cell thick and transparent Photo: LOU JOST Lou Jost, a botanist, found the tiny orchid by accident when he was inspecting a plant collected in a forest in a mountainous region of Ecuador.

When Orme School co-founder Minna Orme, a Stanford University-educated botanist, imported and planted a number of species of trees and flowers at the school beginning in 1929, she set the stage for a distinctive program of sustainability education for many years into the future.

A rare woodland plant, Monotropsis odorata, uses camouflage to hide from predators in much the way some animals do, scientists in Massachusetts said.

The estimation of plant genetic maps is a conceptually simple yet computationally complex problem, growing ever more so with the development of inexpensive, high-throughput DNA markers.

Too much light can damage the photosynthetic machinery and cause cell death. Scientists at the Carnegie Institution were part of a team that found that specific proteins in algae can act as a safety valve to dissipate excess absorbed light energy before it can wreak havoc in cells.

When film director James Cameron needed help to create plant life for the fictional planet in his new film "Avatar," he looked to the University of California, Riverside for help.

As a myco-heterotroph, M. odorata obtains carbon resources from associated mycorrhizal fungi and has a highly reduced vegetative morphology consisting of an underground root mass that produces one to many diminutive... It is well known that some animal species use camouflage to hide from predators.

Researchers unfold a key step in the process that tells plants to flower, findings that could one day benefit agriculture.

Proteolytic enzymes play central role in the biochemical mechanism of germination and intricately involved in many aspects of plant physiology and development.

The Purdue scientists, led by Nicholas Carpita, a professor of plant cell biology, published their findings on the 750 cell wall genes in the journal Plant Physiology on Thursday .

The new map, a special type of gene map known as a haplotype map, charts genetic diversity and recombination across the genome of 27 inbred lines of maize.

Perspectives Plant Science: Solving the Maze Catherine Feuillet1 and Kellye Eversole2 Almost 400 years after Native Americans introduced maize to the pilgrims and joined in celebrating what would become an annual day of giving thanks for the bounty of the harvest, insights from the maize genome sequence, reported on page 1112 of this issue by ...

When it comes to corn, 1 + 1 = more than 2: The offspring of two inbred strains tend to be superior to both of their parents.

After decades of seeing plants as passive recipients of fate, scientists have found them capable of behaviors once thought unique to animals.

A pair of the state's foremost experts in manzanita plants have weighed in that the bush recently uncovered during the Doyle Drive project is a living specimen of the Franciscan Manzanita -- a discovery akin to stumbling across a Dodo or Passenger Pigeon.
