Defrosted Moss Sprouts Anew After 1,500 years in Antarctic Permafrost

moss_core_signy_antarctica_Convey_200

Last year I blogged about the surprising discovery that mosses released after 400 years of frozen glacial ensquashment had managed to survive and sprout new growth, a finding that radically altered our ideas about regrowth during the retreat of ice ages. Now, a new study in Current Biology pushes that back at least a millennium [...]

Flying for Free the Horsetail Spore Way

Equisetum_spores_elaters_wiki_pd_200

In spite of their sedentary reputations (putting down roots being, perhaps, the ultimate symbol of stability), plants are capable of a surprising range of movements, and not just the Venus flytraps of the world. Observe: At :36, the spores appear to scuttle about like dozens of itsy bitsy spiders, and at 1:17 they launch themselves [...]

Love Wine and Tea? Scientists Discover Plant Part Whence Their Pucker Springs

tea_cup_variety_wiki_pd_200

When you take a sip of red wine or black tea, you’re swallowing a stiff swig of tannins. These astringent plant chemicals give the beverages their characteristic pucker. Now, the part of plant cells that makes and transports tannins — long overlooked by botanists — has at last been discovered, hiding right under our noses. [...]

How the Mosses That Got Run Over By a Glacier Survived Their Ordeal

moss_regrowth_pnas_la_farge_et_al_200

A few months ago, scientists revealed that some plucky mosses in Canada managed to do something long thought impossible: survive a 400-year close encounter with the business end of a glacier, and live to sprout another day. The conventional wisdom on glaciers was that they were Earth-scraping, life-razing forces of geology. Nothing could survive their [...]

Are Cycads Social Plants?

cycad_grove_cone_hall_and_walter_2013_200

Botanists have long puzzled over a peculiarity of ancient plants called cycads: they have huge, bright, fleshy seeds displayed in enormous cones. Yet there’s nothing correspondingly ginormous to eat and — I’ll use the polite term here — disperse them. And if their presumed former big dispersers (perhaps super-sized ice age mammals, marsupials, birds — [...]

Mosses Make Two Different Plants From the Same Genome, and a Single Gene Can Make the Difference

Mosses_on_a_tombstone_wiki_cc_ ndrwfgg_200

One of the most astonishing secrets in biology is this: every plant you see makes two different plants from the same genome. And, scientists recently reported, a single gene from an ancient, powerful lineage can make the difference. How can such a truth be so little known? In most land plants, including conifers and flowering [...]

Roots Down, Shoots Up. But How Does a Plant Know Which is Which?

root_amyloplasts_growth_200

When an avalanche tears down a mountain, a revealing, if inadvertant, botanical experiment is sometimes begun. Though trees in the path of the angry snow are often ripped from their roots and deposited unceremoniously downhill, occasionally, overturned trees hold fast. Some roots of these partially upturned trees break and die of exposure. But some remain [...]

Mosses With a Real Inferiority Complex

moss_splash_cup_200

Mosses, which probably already have an inferiority complex, must feel especially inferior in Sequoia National Park. When you stand in the shadows of giants, how will you ever get noticed? If you are lucky, someone like Lena Coleman will come to your rescue. You may have recently read David Quammen’s wonderful profile of The President, [...]

Pesky Glaciers and Differing Geography Forced Faster Conifer Evolution in Northern Hemisphere

araucaria_angustifolia_wiki_pd_200

Southern conifer species have had it easy over the past 65 million years — especially compared to their hard-knock northern kin. Unlike their Southern Hemisphere cousins, whose northward-drifting continents continued to host stable habitats with cozy, Club-Med like conditions similar to those in which these conifers evolved, northern hemisphere conifer species were forced to cope [...]

How Mosses Have Sex in Spite of Their Swimming-Challenged Sperm

moss_splash_cup_200

Last summer I was hiking in the tundra near Gray’s and Torrey’s Peaks when I came upon a moss that looked strange. It had little flattened discs that looked something like this: What were these things? Then I happened to pick up a book called “Gathering Moss“, and suddenly I knew what it was I [...]

Botanists finally ditch Latin and paper, enter 21st century

Badianus-small

While some schoolchildren daydream about crushes during class, delicately inscribing their names in paper margins, others instead yearn to one day discover and name their own species for the cute boy at the corner desk. But they know little about the excess work involved in plant discovery. Even after discovering and confirming a new species [...]

2 Trees Twice Thought to Be Extinct Rediscovered in Tanzania

Erythrina schliebenii

How’s this for luck? Two tree species that scientists believed were extinct—twice—have been rediscovered in a remote area of Tanzania. According to a paper published in the Journal of East African Natural History, the two species were rediscovered in the remote, highly fragmented and rarely explored Namatimbili–Ngarama Forest, 35 kilometers inland from the Indian Ocean.

From Biergartens to Boozegartens: Growing Your Own Cocktails With The Drunken Botanist

Do you know the story of the birds and the bees and the flowers and the trees? Yes, there’s that one. But there’s also a more literal one that involves creation, specifically, how the world’s greatest alcoholic beverages came to be. It seems they are all created from plants–that’s according to an expert on the [...]

A Rose Is a Rose, Until It Isn’t: 5 Reasons Plant DNA Is Totally Crazy

seedling

You may not give your houseplants enough credit. What looks like an innocent philodendron gathering dust may actually be a riddle wrapped in a mystery shrouded in potting soil…at least genetically. Turns out plants have some interesting genetic quirks that keep geneticists guessing. As challenges in finding gene-sequencing shortcuts, called barcodes, have made clear, deciphering plant [...]

Van Gogh’s Sunflowers Were Genetic Mutants

sunflower

The word “sunflower” brings to mind a mane of vibrant yellow petals encircling a dark whorl of seeds. But not all sunflowers are alike. Some sunflowers have scraggly petals, for instance, or small centers. Many of the sunflowers Vincent Van Gogh depicted in his famous series of oil paintings look rather unusual, sporting wooly, chrysanthemum-like [...]

Late Bloomer: Trailblazing 18th-Century Woman Botanist Finally Honored with Namesake

jeanne baret

In the 18th century, not yet 30 years old, she became the first woman to travel around the world. Along the way she helped collect thousands of plant specimens, some of which were new species. And she did it all dressed as a man. In her own lifetime, French botanist Jeanne Baret fought for recognition [...]

Are Sheep Better at Botany than the US Government?

Botanically, a tomato is a fruit: a seed-bearing structure that grows from the flowering part of a plant. In 1893, however, the highest court in the land ruled in the case of Nix v. Hedden that the tomato was a vegetable, subject to vegetable import tariffs. Unfortunately, the vegetal confusion did not end in 1893. [...]
