Many species comprise multiple cytotypes that represent autopolyploids, or presumed
autopolyploids, of the basic diploid cytotype. However, rarely has an autopolyploid been …

The large‐scale replacement of gymnosperms by angiosperms in many ecological niches
over time and the huge disparity in species numbers have led scientists to explore factors …

Tea is the world's oldest and most popular caffeine-containing beverage with immense
economic, medicinal, and cultural importance. Here, we present the first high-quality …

Polyploidy is commonly thought to be associated with the domestication process because of
its concurrence with agriculturally favourable traits and because it is widespread among the …

MicroRNAs (miRNAs) play key roles in plant reproduction. However, knowledge on
microRNAome analysis in autotetraploid rice is rather limited. Here, high-throughput …

Whole genome duplication (WGD) events are common in many plant lineages, but the
ploidy status and possible occurrence of intraspecific ploidy variation are unknown for most …

Analyses of diverse eukaryotes reveal that genomes are dynamic, sometimes dramatically
so. In numerous lineages across the eukaryotic tree of life, DNA content varies within …

There is growing realization that intraspecific polyploidy in plants has important implications
for the evolution of plant diversity and for plant and plant–herbivore community dynamics …

Opium poppy (Papaver somniferum) is a source of morphine, codeine, and semisynthetic
derivatives, including oxycodone and naltrexone. Here, we report the de novo assembly and …

Background Genome doubling may have multi-level effects on the morphology, viability and
physiology of polyploids compared to diploids. We studied the changes associated with …
