Does polyploidy play a role in the onset of the Italian endemic flora?
Besides the obvious differences between plants and animals, subtle ones lie concealed within the cell, even within the nucleus. In both plant and animal cells, the nucleus contains DNA, which condenses into ...

Are genes our destiny? 'Hidden' code in DNA evolves more rapidly than genetic code, scientists discover
A "hidden" code linked to the DNA of plants allows them to develop and pass down new biological traits far more rapidly than previously thought, according to the findings of a groundbreaking study by researchers ...

Jumping gene enabled key step in corn domestication
Corn split off from its closest relative teosinte, a wild Mexican grass, about 10,000 years ago thanks to the breeding efforts of early Mexican farmers. Today it's hard to tell that the two plants were ever close kin: Corn ...
