Heterostyly, a floral polymorphism where a species produces two or three distinct flower types with reciprocal arrangements of stigmas and anthers, boosts pollination accuracy, reduces sexual ...

Polyploidy is a state where a cell contains more copies of the genetic material than the usual "diploid" cell, which contains two copies. Polyploidy often occurs in human diseases and cancers, and its ...

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 ...

Genome assembly of polyploid plant genomes is a laborious task as they contain more than two copies of the genome, are often highly heterozygous with a high level of repetitive DNA. Next Generation ...

One of the biggest challenges in cancer research is understanding why some tumor cells become especially aggressive, invasive and resistant to treatment. Scientists have increasingly linked these ...

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 ...

Polyploidy is a hallmark of cancer, and closely related to chromosomal instability involved in cancer progression. Importantly, polyploid cells also exist in some normal tissues. Polyploid hepatocytes ...

Researchers have created a new way to reconstruct the evolutionary history of complex plant genomes by analyzing genetic traces left by transposable elements. The technique revealed that modern ...

Polyploidization, the combination and duplication of genomes, is a major driver of plant evolution and diversification. Yet this process causes "genome shock," leading to rapid activation of ...

For decades, scientists have struggled to untangle the genetic complexity of crops with multiple chromosome sets. Now, researchers have unveiled a cost-effective sequencing method, dpMIG-seq, that ...

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 ...
