Disease profile
A grounded synthesis of the condition — overview, causes, mechanism, risk factors and current standard of care.
Polyploidy is a chromosomal state in which a cell contains more than the normal number of chromosome sets, such as triploidy or tetraploidy. It is especially common in plants and is discussed in the literature as both an evolutionary phenomenon and a taxonomic/genetic state.
Polyploidy can arise through genome duplication events, including whole-genome duplication. In autopolyploidy, the extra chromosome sets originate from the same species and are associated with polysomic inheritance.
The core biological feature is the presence of multiple chromosome sets, which changes genome dosage and inheritance patterns. The literature also links polyploidy to altered gene expression regulation, transcriptome behavior, gene duplication, and evolutionary change, with effects that may differ under stress and in interactions with pathogens or mutualists.
Environmental stress and disturbed or harsh conditions are associated with the establishment and long-term success of polyploidy. The literature also notes correlations between whole-genome duplications and periods of extinction or global change, and differential effects of biotic interactions such as pathogens or mutualists.
