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

Polyploids — organisms that have multiple sets of chromosomes — are common in certain plant and animal taxa, and can be surprisingly stable. The evidence that has emerged from genome analyses ...

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 ...

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

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

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 ...

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 stabilize young polyploids and how genome doubled ...
