Strawberries by design

...ene transfer using A. tumefaciens. Since they glow green under fluorescent light due to the presence of Green Fluorescent Protein (GFP), transformed strawberry plants may be easily identified by visual inspection. This is the first time that GFP has been used in strawberry as a visually selectable marker. ...

Lizard 'third eye' sheds light on evolution of color vision

... of its head. But when the lizard's third eye sees green light, the green pigment triggers a different molecule called Go, known as "G-other," which also signals light respon...

UF researchers develop ways to keep the bloom on the rose

...ed to lilies and alstromeria, to keep their leaves green even after they go into a vase. Previously the leaves of these crops were susceptible to yellowing, said Nell. He anticipates that floral sales will increase if flowers perform better by withstanding the test of time. "It is already proven that fl...

Sea coral's trick helps scientists tag proteins

... the sea coral Dendronephthya--first shows up as a green glow, highlighting the otherwise invisible protein to which it is attached. The green turns to red when the tags are zapped with an intense pulse of visible blue light. The dramatic col...

Researchers release new variety of asparagus

...ranch out to form the "fern" which is the feathery green leaves and stems of the plant. Spears are not usually harvested until plants are two years old in order to allow the crown to become large and healthy. During spring and the early summer of the third year, the crown produces spears, which are harves...

Red Tide causes sea turtle die-off in El Salvador

...ng reptiles--mostly olive ridley turtles and a few green and hawksbill turtles--were dying in such high numbers. Tissues collected from dead turtles, and analyzed by both U.S. biologists and researchers from the Mexican Autonomous University, revealed the culprit: saxitoxin, which is produced by the specie...

Tiny polyps gorge themselves to survive coral bleaching

...that happens, the symbiotic algae and the brown or green photosynthetic pigments inside are lost. The result is a "bleached" white coral. "In most cases, corals get 100 percent of their daily metabolic energy needs from the algae. Once they are gone, the coral polyp is left with only two alternatives: Dr...

Sweetgum tree could help lessen shortage of bird flu drug

Parents need to be educated about HPV vaccinations for daughters

...elop. Vaccination should not be misconstrued as a green light for sexually permissive behaviour ?rather, it is an effective means of preventing HPV infection when young women are most susceptible in their teenage and young adult years. "The origins of cervical cancer lie in HPV infection of the cervix, a...

In sorting out centrin's role in the Vorticella spring, France and colleagues found that an antibody to Vorticella centrin abolished contractility. Along with other evidence, this interference suggests that the spasmoneme uses a ...

The brain is broadly wired for reproduction

... upstream and downstream to connected neurons, and green fluorescent protein (GFP), to mark the producing cells. By visualizing the locations of BL, GFP, and GnRH neurons and their axons, the researchers were able to identify neurons directly connected to GnRH neurons. They also determined which neurons se...

Algal protein in worm neurons allows remote control of behavior by light

...rchers employed a light-sensitive protein from the green alga Chlamydomonas reinhardtii. This protein, channelrhodopsin-2 (ChR2), sits in cell membranes, where it gates the flow of certain ions from one side of the membrane to the other. Such so-called channel proteins play central roles in the activities ...

Sperm stem cells closer to being like embryonic stem cells

... "tag" that specifically labeled germ cells with a green fluorescent protein, making the germ cells easier to identify when mixed with other cell types. "The rat testes contain other cells types in addition to stem cells," Dr. Hamra said. "If these other cells are included in the culture, they produce ch...

New GM mosquito sexing technique is step towards malaria control, report scientists

Sulfate reduction is also a microbial process where organisms turn sulfate into sulfide, a corrosive compound or gas that smells like rotten eggs. Methanogenesis is a 2.7?.2-billion-year-old process and sulfate reduction originated at lea...

Researchers quantify more noise in gene expression

...sed genetically engineered strains of yeast with a green fluorescence marker linked to a gene involved in the metabolism of the sugar galactose. The galactose gene and 10 others were chosen because they are expressed in yeast cells in high copy numbers, a feature that makes intrinsic noise in their express...
