When the world goes bad, some plants do something astonishing. They can’t run or hide, nor can they do much about changing ...

A collaborative effort by the Formosa-Jordan lab from the Max Planck Institute for Plant Breeding Research in Cologne, Germany, the Fox lab from Duke University, U.S., and the Roeder lab from Cornell ...

Unlike humans, many plants have more than two sets of chromosomes. This trait may help them adapt to environmental upheaval, such as climate change.

Assistant Professor of Biology Vicki Losick admits she harbors a desire to change the world a little bit. “I want to make ‘polyploidy’ a household word,” Losick said in her Higgins Hall office, next ...

Biologists may have pinpointed for the first time the mechanism responsible for cell polyploidy, a state in which cells contain more than two paired sets of chromosomes. An international team of ...

Scientists have long known that some cells in a given tissue undergo a process of duplicating their entire genome without dividing – a process called endopolyploidy, where cellular ploidy is the copy ...

The placenta, critical for healthy embryo development, is a multi- purpose organ with a precise lifespan—the length of a pregnancy. New research from the Stowers Institute for Medical Research ...

For animals, inheriting more than the usual two copies of DNA is usually a very bad thing. It can happen when two sperm fertilize one egg, or when sexual cell division errs, leaving a sperm or an egg ...

Confocal microscopy is performed with nuclear reporters and stains, nuclear segmentation with ilastik is conducted, and a machine learning method is used to classify the ploidy of each nucleus. Colors ...
