A cereal crop survives heat and drought
Scientists have published the genome sequence of Pearl millet, a drought resistant crop plant most important in arid regions in Africa and Asia. This plant is important to small and medium farmers who grow the plant without larger irrigation. Pearl millet delivers a good harvest index under drought and heat conditions when rice, maize or wheat already have no grains anymore.

RNA discovery could help boost plant heat, drought tolerance
The discovery of a RNA that can increase drought and salt tolerance in thale cress could illuminate a new research approach and hold implications for other plants, including food crops.

Dogs' social skills linked to oxytocin sensitivity
The tendency of dogs to seek contact with their owners is associated with genetic variations in sensitivity for the hormone oxytocin, according to a new study. The results contribute to our knowledge of how dogs have changed during their development from wolf to household pet.

Genomic recycling: Ancestral genes take on new roles
One often hears about the multitude of genes we have in common with chimps, birds or other living creatures, but such comparisons are sometimes misleading. The shared percentage usually refers only to genes that encode instructions for making proteins -- while overlooking regulatory genes, which nonetheless make up a large part of the genome.

Sheep gene insights could help farmers breed healthier animals
Fresh insights into the genetic code of sheep could aid breeding programs to improve their health and productivity. Scientists have now mapped which genes are turned on and off in the different tissues and organs in a sheep's body.

Membrane vesicles released by bacteria may play different roles during infection
Bacteria release membrane-derived vesicles (MVs), which are small particles that can transport virulence factors to neighboring bacteria or to the cells of a mammalian host. This special MV-based system for delivering toxic proteins and nucleic acids in a protected manner to the target cells may have different specific functions depending on whether the bacterium acts as an extracellular or intracellular pathogen.

Innate immunity: To operate, insert dimers
The presence of DNA in mammalian cell cytoplasm triggers an immune response by binding to a dimeric enzyme, which inserts between DNA double helices to form the “rungs” of a ladder-like structure, as an LMU team has now shown.
