Plant engineered for more efficient photosynthesis
(Phys.org) —A genetically engineered tobacco plant, developed with two genes from blue-green algae (cyanobacteria), holds promise for improving the yields of many food crops.

'Most famous wheat gene' found
Washington State University researchers have found "the most famous wheat gene," a reproductive traffic cop of sorts that can be used to transfer valuable genes from other plants to wheat.
How an ancient vertebrate uses familiar tools to build a strange-looking head
If you never understood what "ontogeny recapitulates phylogeny" meant in high school, don't worry: biologists no longer think that an animal's "ontogeny", that is, its embryonic development, replays its entire ...
Coffee genome sheds light on the evolution of caffeine
Enzymes that help produce caffeine evolved independently in coffee, tea and chocolate, say scientists who have newly sequenced the coffee plant genome.
What happens when good genes get lost?
Scientifically speaking, there is no bad DNA, though we like to blame it for unruly hair, klutziness or poor gardening skills. There is, however, junk DNA.
Geneticists solve 40-year-old dilemma to explain why duplicate genes remain in the genome
Geneticists at Trinity College Dublin have made a major breakthrough with important implications for understanding the evolution of genomes in a variety of organisms.
New genetic 'operating system' facilitated evolution of 'bilateral' animals
The evolution of worms, insects, vertebrates and other "bilateral" animals—those with distinct left and right sides—from less complex creatures like jellyfish and sea anemones with "radial" symmetry may have been facilitated ...
At dusk and dawn: Scientists pinpoint biological clock's synchronicity
Scientists have uncovered how pacemaker neurons are synchronized at dusk and dawn in order to maintain the proper functioning of their biological clocks. Their findings, which appear in the journal PLOS Biology, enhance our un ...
In stickleback fish, dads influence offspring behavior and gene expression
Researchers report that some stickleback fish fathers can have long-term effects on the behavior of their offspring: The most attentive fish dads cause their offspring to behave in a way that makes them less ...
Human genome was shaped by an evolutionary arms race with itself
New findings by scientists at the University of California, Santa Cruz, suggest that an evolutionary arms race between rival elements within the genomes of primates drove the evolution of complex regulatory networks that ...
Penn team studies nanocrystals by passing them through tiny pores
An interdisciplinary team of University of Pennsylvania researchers has now applied a cutting-edge technique for rapid gene sequencing toward measuring other nanoscopic structures. By passing nanoscale spheres ...
Team engineers 'Cas9' animal models to study disease and inform drug discovery
Researchers from the Broad Institute and Massachusetts Institute of Technology have created a new mouse model to simplify application of the CRISPR-Cas9 system for in vivo genome editing experiments. The researchers successfully ...
Recreating the stripe patterns found in animals by engineering synthetic gene networks
Pattern formation is essential in the development of animals and plants. The central problem in pattern formation is how can genetic information be translated in a reliable manner to give specific spatial ...
