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 ...

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 ...

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 ...

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 ...

Researchers at Tulane University School of Medicine have discovered that if animal cells gain an extra set of chromosomes, a condition known as polyploidy, they activate a stress signaling pathway ...

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 ...

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 ...

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 ...
