DNA hypermethylation of abscisic-acid-related genes helps enhance the cold tolerance of tetraploid rice.
Polyploid plants exhibit enhanced stress resistance and superior adaptability to extreme environments, but the underlying molecular mechanisms remain incompletely understood. Here we confirm that tetraploid rice exhibits stronger cold tolerance than diploid rice. This improved tolerance is mediated by reduced malondial...
