Heredity - Polyploids and hybrids in changing environments: winners or losers in the struggle for adaptation?

Polyploids are common among plants, as well as among certain groups of fish and amphibians. How does this interesting condition crop up, and what advantages and disadvantages does it impart?

A study (DOI: 10.48130/vegres-0024-0005) published in Vegetable Research on 05 February 2024, offers a comprehensive overview of research on vegetable polyploids facilitated by high-throughput ...

American Journal of Botany, Vol. 96, No. 9 (Sep., 2009), pp. 1636-1645 (10 pages) Deciphering species relationships and hybrid origins in polyploid agamic species complexes is notoriously difficult.

Published by the Botanical Society of America continuously since 1914, the American Journal of Botany (AJB) is the Society’s flagship research journal. AJB publishes peer-reviewed, innovative, ...

Genome duplications occur spontaneously in a range of taxa, and problems such as sterility, aneuploidy and gene expression aberrations are common in newly formed polyploids. In mammals, genome ...

In brief Plants with multiple sets of chromosomes, known as polyploids, are salt-tolerant or drought-resistant and often achieve higher yields. However, newly formed polyploid plants are often sterile ...

Because polyploids have more genomes to manage, the doubling of these genomes can be a weakness, so it is important to understand what factors stabilise young polyploids and how genome doubled ...
