Ethylene of no effect: Why peppers do not mature after picking

(Phys.org) -- The plant hormone ethylene lets green tomatoes ripen even after the harvest, whereas the closely related chili peppers show no such effect. Researchers from the Max-Planck-Institute of Molecular Plant Physiology ...

New PRA gene identified in Phalenes and Papillons

Finnish researchers have identified a genetic mutation causing progressive retinal atrophy (PRA) in the Phalene and Papillon dog breeds. PRA is one of the most common causes of blindness in dogs and in human. This study highlights ...

DNA repeats—the genome's dark matter

Expansions of DNA repeats are very hard to analyze. A method developed by researchers at the Max Planck Institute for Molecular Genetics in Berlin allows for a detailed look at these previously inaccessible regions of the ...

Scientists engineer synthetic DNA to study 'architect' genes

Researchers at New York University have created artificial Hox genes—which plan and direct where cells go to develop tissues or organs—using new synthetic DNA technology and genomic engineering in stem cells.
