How green plants expand their capacity to use solar energy? - Tech ExploristSunday, February 10, 2019
Schlau-Cohen’s lab said, “Solar energy devices must absorb a large fraction of the solar spectrum — i.e., many different energies or colors — to be competitive with fossil fuels. Absorption of these energies comes with a challenge: How can the high energy be funneled down to the low energy, which is what is used to produce electricity and eventually biomass?”“We mapped out pathways of energy flow that connect the high energy side to the low energy side of the absorbed solar spectrum, including one pathway through a previously-debated dark state. This map provided a blueprint for solar energy devices that absorb a lot of energy across a broad range, as well as provides an important step in understanding the intricate photosynthetic machinery of plants.”The research is described in “The Electronic Structure of Lutein 2 Is Optimized for Light Harvesting in Plants,” which is featured on the cover of the March 2019 issue of the journal Chem, which was released online on Jan. 31. https://www.techexplorist.com/how-green-plants-expand-their-capacity-to-use-solar-energy/20755/
Shrinking to grow: flowering plants conquered the world by reducing their genomes - CosmosTuesday, January 16, 2018
To pursue their theory, Simonov says he and Roddy are going to back to examine the fossil record: “If we’re right you’d expect to see genome down-sizing just before an increase in vein density.”...
Peffley: Magnolia one of most primitive seed-bearing plants - LubbockOnline.comTuesday, November 28, 2017
Evolution and Classification of Flowering Plants, Cronquist 1988).Magnolia fossils have been dated to between 36 and 58 million years, making this one of the oldest angiosperms still living. The magnolia has been dated to this age because it exhibits primitive characteristics, all of which involve its reproductive (flowering and fruiting) system.The fossil records provide evidence that the primitive blooms of magnolia have changed little since their ancient beginnings. One characteristic of primitive plants is the magnolia flower. The large, saucer-shaped fragrant blooms have petals that are fused with other flower parts to form thick, showy structures called tepals.The male parts of the flower that produce pollen are arranged at the base of the female part that contains the ovary. When the ovary is mature, it will form the fruit. Once pollination has taken place, the male pollen-bearing bodies fall away, revealing a cone-like ovary where seeds will develop, a second characteristic of primitive angiosperms.Beetles are the vectors for pollination, a third characteristic of primitive flowering plants. Beetles are attracted by the pungent fragrance of the flowers, where rather than seeking nectar, high-protein pollen that is positioned to ensure beetles must crawl across the male to reach female parts of the flower.The formation of tepals is significant because the tepals of the magnolia flower are tough enough to prevent damage from munching beetles.The bizarre-appearing fruit that results from the development of the maturing ovary following pollination resembles a cone but is botanically a dry aggregate fruit (think an inside out pomegranate). The image in the photo is a mature ovary, the fruit, of the Southern Magnolia.Male parts that were initially on the far end have been shed and are no longer visible. The female part contained the developing seeds, most of which have now tumbl... http://lubbockonline.com/life/news/2017-11-06/peffley-magnolia-one-most-primitive-seed-bearing-plants
Revealed: The First Flower, 140-million Years Old, Looked Like a Magnolia - Scientific AmericanTuesday, August 01, 2017
This is partly because these first flowers left no traces. Flowers are fragile structures that only in the luckiest of circumstances can be transformed into fossils. And, as no fossil has been found dating back 140m or more years, scientists have only had a limited sense of what the ultimate ancestor would have looked like. Until now.A major new study by an international team of botanists has achieved the best reconstruction to date of this ancestral flower. The research, published in Nature Communications, relies not so much on fossils as on studying the characteristics of 800 of its living descendant species.By comparing the similarities and differences among related flowering plants, it is possible to infer the characteristics of their recent ancestors. For example, because all orchid species have flowers in which one half is the mirror image of the other (bilateral symmetry), we can suppose that their ancestor must have had bilateral flowers. By comparing those recent ancestors to each other it is then possible to go a step further back in time, and so on, until eventually we reach the base of the flowering plants’ family tree.So what did it look like?In some respects, the original flower resembles a modern magnolia: it has multiple, undifferentiated “petals” (technically tepals), arranged in concentric rings. At its centre there are multiple rows of sexual organs including pollen-producing stamens and ovule-bearing ovaries. It is hard to resist the temptation to imagine ancient pollinators crawling in this flower, collecting pollen grains while unknowingly helping the plant to produce seeds.A controversial sex lifeThe new study helps to settle the controversy about whether early flowers had separate sexes, or whether both male and female reproductive organs were combined in the same flower. Previous evidence pointed to different answers. On the one hand, one of the ...
The earliest flower ancestor had both male and female parts - The VergeTuesday, August 01, 2017
Angiosperms account for about 90 percent of all plants.) This is partly because flowers don’t preserve well, so fossils are rare. For a study published today in the journal Nature Communications, researchers used a database of flower traits and computer models of how flowers evolve to figure out what this ancestor might have looked like. It rather resembles a white lily, with three layers of petals, called “whorls.” The models suggest that this first flower was bisexual, meaning it had both male and female flower parts in the middle. The findings are a jumping-off point for more research into flower evolution. It can help us fill in the gaps and figure out how the descendants of this creature adapted to different environments and became magnolias, daisies, and all the other flowers. The models used in the study are speculative, so we don’t know all the details about this flower ancestor. But there’s something comforting about knowing that a flower from 140 million years ago doesn’t look that different from something you could find at a florist’s shop today.
A Pop-Up Shop at a Portland Florist Is Selling Cannabis Bouquets - The Portland MercuryTuesday, February 05, 2019
Southeast Hawthorne will be host to a "Cannabis Flower Bouquet Pop-Up." Among their usual flowers and greenery, these colorful collections contain extremely fresh and subtly fragrant Oregon sun-grown hemp flowers from East Fork Cultivars. Starflower will be selling "bud vases" that contain some gorgeous, CBD-dominant, very-low-THC, and terpene-rich cannabis flower (AKA craft hemp), along with non-cannabis flowers in the arrangement for $15, $20, and $25, with full bouquets from $50 to $100 upon request. These beauties got comments from my Lyft drivers to and from the Mercury offices to be photographed. They have a mild cannabis smell—not an overpowering skunk aroma, but one certainly indicative of their shared linage with its THC-heavy relative. The buds are vibrant and rich, and pair remarkably well with the other flowers. “We've wanted to create and sell cannabis flower bouquets for years," writes East Fork Cultivars' co-founder and president, Nathan Howard.

Bullard, ‘Top Chef’ finalist Doug Adams’ Texas-inspired Portland restaurant, opens Saturday - OregonLive.comMonday, December 17, 2018
The whiskey is arranged behind the bar. The hearth fire is burning in the open kitchen. And the fictional flag of Bullard -- a custom cross between the flags of Texas and Oregon, complete with Texas longhorns pulling a covered wagon -- is hanging on the wall.As first reported by The Oregonian/OregonLive way back in September 2016, Bullard is meant to reflect both Adams’ Texas upbringing and his current Oregon home. In practice, that means carefully sourced meat, fish and produce, much of it treated with smoke or live fire, alongside veggie-forward Southern sides. In my head, I’ve been calling it “Tex-Oregana.” I’m not sure that will stick.The restaurant isn’t the only thing opening Saturday. Alongside Bullard, the Woodlark will debut in the historic Woodlark and Cornelius buildings on Southwest Alder Street. Next week, on the other side of the hotel, Quist and Adams will launch Abigail Hall, a handsome cocktail bar with hand-painted flowers on the walls and painstakingly recreated historical details throughout. In the lobby, the folks from Good Coffee will serve espresso and Texas-style smoked sausage kolaches baked each day at Bullard.Downtown's newest hotel combines two historic buildingsLeaning back on one of those booths, George Harrison and The Band playing softly through the restaurant’s speakers, Adams seems a little dazed and confused that his dream restaurant is actually about to open.“It’s so fortunate to get to do this, to have so many people help you with your dream, and then two years later it’s like, whoa, I didn’t know I had such awesome taste!" Adams laughs. "Sure, I didn’t get my stuffed grizzly bear…”“Next year,” Quist jokes. “At the one-year anniversary.” The fictional flag of Bullard, a blend of the Oregon and Texas flags, complete with Texas longhorns pulling a covered wagon.
