Secret Weapon of Smart Bacteria Tracked To "Sweet Tooth"

Researchers have figured out how a once-defeated bacterium has re-emerged to infect cotton in a battle that could sour much of the Texas and U.S. crop. And it boils down to this: A smart bacteria with a sweet tooth.

ESF Lists Top 10 New Species for 2017

A spider and an ant with names drawn from popular books, a pink katydid and an omnivorous rat made ESF's list of the Top 10 New Species for 2017. Also listed: a freshwater stingray, a bush tomato that appears to “bleed,” a devilish-looking orchid, a millipede with more than 400 legs, an amphibious centipede and a marine worm.

Plants Call 911 to Help Their Neighbors

plants-signals-ud.jpg

A University of Delaware professor teamed with a local high school student on research that found injured plants will send out warning signals to neighboring plants. The signals are sent through airborne chemicals released mainly from leaves, and plants that received them boosted their defenses.

UF-Developed Mandarin Shows Increased Tolerance to Greening

SugarBellemandarin051517.jpg

UF/IFAS researchers have discovered that a mandarin hybrid developed by colleagues contains cellular activity – known as metabolites -- that makes it more able to fend off greening than most other types of citrus.

A Carnivorous Plant’s Prized Genetic Treasures, Unveiled

bladderwort1.jpg

The carnivorous humped bladderwort plant, Utricularia gibba, is a sophisticated predator. It uses vacuum pressure to suck prey into tiny traps at speeds less than a millisecond. A new genomic analysis shows that, over millions of years, it repeatedly retained and enhanced genetic material associated with its carnivorous nature. These include genes that facilitate the trapping of prey, the digestion of proteins, and the transport of small bits of protein from one cell to another.

Oldest Buckthorn Fossilized Flowers Found in Argentina

Around 66 million years ago, at the end of the Cretaceous period, a giant asteroid crashed into the present-day Gulf of Mexico, leading to the extinction of the non-avian dinosaurs. How plants were affected is less understood, but fossil records show that ferns were the first plants to recover many thousands of years afterward. Now, a team including Cornell researchers reports the discovery of the first fossilized flowers from South America, and perhaps the entire Southern Hemisphere, following the extinction event

The Evolutionary Story of Birch, Told Through 80 Genomes

silver-birch.jpg

A new study sequences the genomes of 80 silver birch trees, a tree that has not been studied much by scientists despite its commercial value for papermaking, construction, furniture-building and more. Researchers identified genetic mutations including mutations that may affect how well birch trees grow and respond to light at different latitudes and longitudes and under different environmental conditions. The research could help breed trees that better meet the needs of various industries.
