Blossom end rot on tomatoes and cucumbers, bitter-pit in apples — these unpleasant blemishes on fruits and vegetables not only compromises the flavor but also causes significant harvest losses every year. The characteristic blotches and spotting can be traced back to insufficient calcium uptake or faulty calcium transport within the plant. Consequently, the damage can occur even if the soil provides sufficient calcium. A team under the leadership of scientists from the University of...

Research at Iowa State University has led to discovery of a genetic method that can increase biomass in algae by 50 to 80 percent. The breakthrough comes from expressing certain genes in algae that increase the amount of photosynthesis in the plant, which leads to more biomass. Expressing genes means that the gene's function is turned on. "The key to this (increase in biomass) is combination of two genes that increases the photosynthetic carbon conversion into organic matter by 50...

Max Planck scientists discover photosynthesis helper protein in red algae Photosynthesis is one of the most important biological processes. However, it is less efficient in plants than it could be. Red algae, in contrast, use a slightly different mechanism and are thus more productive. Scientists from the Max Planck Institute of Biochemistry (MPIB) in Martinsried near Munich, Germany, have now identified a so far unknown helper protein for photosynthesis in red algae. “We could...

The discovery of a new gene is helping researchers at Michigan State University envision more-efficient molecular factories of the future. A team of researchers, led by Katherine Osteryoung, MSU plant biologist, announced the discovery of Clumped Chloroplasts — a new class of proteins — in the current issue of the Proceedings of the National Academy of Sciences. CLMP1 plays a key role in helping chloroplasts, which carry out the life-sustaining process of photosynthesis,...

Taking a cue from Mother Nature, researchers at the Department of Energy's BioEnergy Science Center have undertaken a first-of-its-kind study of a naturally occurring phenomenon in trees to spur the development of more efficient bioenergy crops. Tension wood, which forms naturally in hardwood trees in response to bending stress, is known to possess unique features that render it desirable as a bioenergy feedstock. Although individual elements of tension wood have been studied previously,...

Biologists at the University of California, San Diego have succeeded in unraveling, for the first time, the complete chain of biochemical reactions that controls the synthesis of auxin, the hormone that regulates nearly all aspects of plant growth and development. Their discovery, detailed in a paper in this week's online edition of the Proceedings of the National Academy of Sciences, will allow agricultural scientists to develop new ways to enhance or manipulate auxin production to...

International Panel of Scientists Point the Way Forward Photosynthesis is one of nature´s finest miracles. Through the photosynthetic process, green plants absorb sunlight in their leaves and convert the photonic energy into chemical energy that is stored as sugars in the plants´ biomass. If we can learn from nature and develop an artificial version of photosynthesis we would have an energy source that is absolutely clean and virtually inexhaustible. “Solar energy is...

  Clean solutions to human energy demands are essential to our future. While sunlight is the most abundant source of energy at our disposal, we have yet to learn how to capture, transfer and store solar energy efficiently. According to University of Toronto chemistry professor Greg Scholes, the answers can be found in the complex systems at work in nature. "Solar fuel production often starts with the energy from light being absorbed by an assembly of molecules," said Scholes, the...

The best fall foliage colors can be seen by spending several days in the Blue Ridge Mountains and the Shenandoah National Park, and driving around each of those days. Choosing to stay in a cabin rental in Virginia provides a great base from which to explore. Waynesboro, VA (PRWEB) September 17, 2011 âœWhen should I come to see the peak colors?â This question causes the phones at Cabin Creekwood to ring off the hook as the days get shorter and the...

Bittercress (Barbarea vulgaris), also commonly known as Herb Barbara, Rocketcress, Yellow Rocketcress, Winter Rocket, and Wound Rocket, is a European biennial herb. This plant displays a rosette of shiny, dark green leaves at the base and additional pinnately divided leaves on the stem. In the spring, yellow flowers originate in tightly packed terminal groups just above the foliage. Bittercress grows wildly as a weed in many parts of North America. The flowers can be in bloom May...

The Par Rubber Tree (Hevea brasiliensis), is a tree belonging to the family Euphorbiaceae. It is the most economically important member of the genus Hevea. It is of major economic importance because its sap-like extract (latex) can be collected and is the primary source of natural rubber. The Pará rubber tree initially grew only in the Amazon Rainforest. Now most rubber tree plantations are in southeast Asia and tropical Africa. Attempts to cultivate the tree in other areas in South...
