One species, many genomes

...ence gathered with Arabidopsis to twenty different rice varieties. How environment and genome interact is also the goal of new, even more powerful methods. While the technology used so far can only identify genes that have changed or are lost relative to the reference genome, direct sequencing of the ge...

Research identifies protein that signals flowering in squash plants

...r in late spring or early summer. SD crops include rice and maize, and LD crops include wheat, barley, oats and peas. Day-neutral plants will flower under either long or short days. In addition to its fundamental importance in basic plant biology, understanding and manipulating the photoperiodic control o...

Researchers demonstrate way to control tree height

...of the “Green Revolution,” in which plants such as rice or wheat were created that directed less energy to height growth and more to development of stout stems and plentiful seed. In orchards, semi-dwarf fruit trees produce more fruit that is easier to harvest. The improvements in cereal yields have been ...

Genome archaeology illuminates the genetic engineering debate

... in much of the third world and a bio-fuel source; rice is the primary dietary staple for more than half the world's population. Scientists have long known that the number of chromosomes among some plant species has changed over time, with some evolutionary phases showing four, six, eight or more sets....

From hot springs to rice farms, scientists reveal new insights into the secret lives of archaea

... It turns out that the international demand for rice is one of the main drivers of methane production on the planet. Studies have shown that rice farming contributes between 10 and 25 percent of global methane emissions, thanks in large part to m...

A green way to slag off bunnies

...s used ultrasonics to freeze strawberries, process rice and handle many other applications. The researchers are also using microcellular foaming technologies from Trexel Inc. of Woburn, Mass., to mold and extrude the plastics. The processing technology is expected to enhance the biodegradable plastics ...

Metal homeostasis research in plants will lead to nutrient-rich food and higher yielding crops

...sumption studies suggest that doubling the Iron in rice can increase the Iron intake of the poor by 50 percent. Rice is a staple food in many of the countries with widespread Iron deficiencies in human diets. Guerinot's lab has previously identified the essential Iron transporter responsible for Iron u...
