Flowering Plant Revived After 30,000 Years In Russian Permafrost -- ABC News

The plant in this picture dates from the Pleistocene Age, 30,000 years ago, before agriculture, before writing, before the end of the last Ice Age. And while it’s not accurate to say the plant itself is that old, scientists in Russia say they regenerated it from frozen cells they found beneath 125 feet of permafrost in what is now northeastern Siberia.

Which Plants Will Survive Droughts, Climate Change? -- Science Daily

ScienceDaily (Apr. 6, 2012) — New research by UCLA life scientists could lead to predictions of which plant species will escape extinction from climate change.

Droughts are worsening around the world, posing a great challenge to plants in all ecosystems, said Lawren Sack, a UCLA professor of ecology and evolutionary biology and senior author of the research. Scientists have debated for more than a century how to predict which species are most vulnerable.

Using Plants In The Fight Against Terrorism

The Latest Weapon In The Fight Against Terrorism: How Scientists Have Developed Plants That Can Detect Bombs -- The Daily Mail

They provide us with food and are pretty to look at, and now they may even save out lives.

For unlikely as it may seem, scientists have developed plants that can detect bombs.

They have taught plant proteins to change colour when in the presence of certain chemicals.

The implications of the study are not hard to see - ringing an airport security gate, for instance, with such plants could prove a lifesaver should a terrorist approach with an explosive and a whole wall of leaves turn white.

From The BBC:

One-fifth of the world's plants - the foundation of life on Earth - are at risk of extinction, a study concludes.

Researchers have sampled almost 4,000 species, and conclude that 22% should be classified as "threatened" - the same alarming rate as for mammals.

A further 33% of species were too poorly understood to be assessed.

The analysis comes from the Royal Botanic Gardens at Kew, the Natural History Museum and International Union for the Conservation of Nature (IUCN).

From Science Daily:

Science Daily (Mar. 17, 2010) — Flowering plants may be considerably older than previously thought, says a new analysis of the plant family tree.

Previous studies suggest that flowering plants, or angiosperms, first arose 140 to 190 million years ago. Now, a paper to be published in the Proceedings of the National Academy of Sciences pushes back the age of angiosperms to 215 million years ago, some 25 to 75 million years earlier than either the fossil record or previous molecular studies suggest.

by a genetic mutation. Credit: stock.xchng.

From Live Science:

The leaves of clover plants are said to hold the luck o' the Irish when they sport four leaves. This myth likely arose because four-leaf clovers are rare finds — the result of an equally rare genetic mutation in the clover plant.

There are about 300 species in the clover genus Trifolium, or trefoil, so named because the plants usually have three leaves, or technically, leaflets. The ones you typically find in North America are white clover (Trifolium repens).

Pretty In Pink: One Of World's Rarest Camellias Blooms In London Conservatory

A 'Middlemist's red' camellia, thought to be one of only two examples of the variety in the world, at the Chiswick House Gardens conservatory, London

From The Daily Mail:

It lived through the Battle of Trafalgar, survived the reign of Victoria and escaped unharmed from a Blitz bomb.

So it's going to take more than a harsh British winter to stop one of the world's rarest camellias from bursting into flower.

This week - in a welcome sign that spring is just around the corner - the "Middlemist's red" has put on one of its most spectacular displays in many years.

From Cosmos/AFP:

TOKYO: Japanese researchers last week said they had found a way to make plant leaves absorb more carbon dioxide - an innovation that may help ease global warming and boost food production.

The Kyoto University team found that soaking germinated seeds in a protein solution raised the number of pores, or stomas, on the leaves that inhale CO2 and release oxygen, said chief researcher Ikuko Hara-Nishimura.

"A larger number means there are more intake windows for carbon dioxide, contributing to lowering the density of the gas," she said.

From Live Science:

Petunias and potatoes may actually be carnivorous plants, scientists now suggest.

Indeed, carnivorous behavior may be far more widespread in plants than commonly thought — if we take a closer look, botanists said.

At least six different kinds of killer plants have been recognized since the time of Darwin, such as Venus flytraps, which snares insects between its jaw-like leaves, and pitcher plants, which capture victims in slippery pits. These plants apparently target animals to supplement their growth in harsh, nutrient-poor habitats.

From The Independent:

Botanists at Kew discover the plant is carnivorous, with ability to trap insects.

Vegetarians, look away now.

Potatoes and tomatoes make good eating but they may also have a vicious side that makes them deadly killers on a par with venus fly traps and pitcher plants.

They have been identified as among a host of plants thought to have been overlooked by botanists and explorers searching the world’s remotest regions for carnivorous species.

From Science Daily:

Science Daily (Dec. 1, 2009) — 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? A new study in Ecology Letters reveals the evolutionary trigger which led to early flowering plants gaining a major competitive advantage over rival species, leading to their subsequent boom and abundance.

From The BBC:

Hundreds of experts from 50 nations are set to agree on a "DNA barcode" system that gives every plant on Earth a unique genetic fingerprint.

The technology will be used in a number of ways, including identifying the illegal trade in endangered species.

The data will be stored on a global database that will be available to scientists around the world.

The agreement will be signed at the third International Barcode of Life conference in Mexico City on Tuesday.

From Live Science:

Plants can't see or hear, but they can recognize their siblings, and now researchers have found out how: They use chemical signals secreted from their roots, according to a new study.

Back in 2007, Canadian researchers discovered that a common seashore plant, called a sea rocket, can recognize its siblings – plants grown from seeds from the same plant, or mother. They saw that when siblings are grown next to each other in the soil, they "play nice" and don't send out more roots to compete with one another.

Plants And Wasps Are Smarter Than You Think

From The Christian Science Monitor:

Seedlings know when they're from the same plant, and wasps get smarter as they get tougher tasks, studies show.

Plants and pea brains can be smarter than you think. Plants like those that discriminate between siblings and strangers within their own species, that is. And pea brains like the tropical paper wasp that reorganizes its tiny brain to tackle increasingly complex tasks.

These research tidbits illustrate the fact that acquiring and using information is a fundamental aspect of organic life.

From Science Daily:

Scientists have shown that the main shoot dominates a plant’s growth principally because it was there first, rather than due to its position at the top of the plant.

Collaborating teams from the University of York in the UK and the University of Calgary in Canada combined their expertise in molecular genetics and computational modelling to make a significant discovery that helps explain why pruning encourages plants to thrive.

From The New York Times:

Throughout his life, Charles Darwin surrounded himself with flowers. When he was 10, he wrote down each time a peony bloomed in his father’s garden. When he bought a house to raise his own family, he turned the grounds into a botanical field station where he experimented on flowers until his death. But despite his intimate familiarity with flowers, Darwin once wrote that their evolution was “an abominable mystery.”
