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

Polyploids are broadly classified as either allopolyploids that contain more than two distinct genomes, or autopolyploids, which have multiples of the same genome.

A new study, led by experts at the University of Nottingham, has shown that different plant species tackle the same evolutionary hurdle in different ways, and the findings may give insight into ...

Several cytotypes (polyploids and aneuploids) have been reported in Lepisorus thunbergianus. The relationships between these cytotypes within the species remain poorly understood. We studied ...

Wild polyploid strawberries hold clues to how plants evolve and adapt to harsh environments. In this study, scientists sequenced the genomes of two ...

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 ...

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 ...

Twisted pollen tubes induce infertility Date: April 16, 2024 Source: ETH Zurich Summary: Plants with multiple sets of chromosomes, known as polyploids, are salt-tolerant or drought-resistant and ...

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 ...
