Coffea arabica, an allotetraploid hybrid of Coffea eugenioides and Coffea canephora, is the
source of approximately 60% of coffee products worldwide, and its cultivated accessions …

Ancient whole-genome duplications (WGDs or polyploidy) are prevalent in plants, and some
WGDs occurred during the timing of severe global environmental changes. It has been …

Polyploidy is a key mechanism of genome evolution and speciation, particularly in plants.
Many aspects of polyploidy have been elucidated with the tools that have become available …

Polyploidy, defined as the coexistence of three or more complete sets of chromosomes in an
organism's cells, is considered as a pivotal moving force in the evolutionary history of …

Background Despite the prevalence and recurrence of polyploidization in the speciation of
flowering plants, its impacts on crop intraspecific genome diversification are largely …

Genome size is a biodiversity trait that shows staggering diversity across eukaryotes, varying
over 64,000-fold. Of all major taxonomic groups, land plants stand out due to their …

Drought is a major environmental factor limiting wheat production worldwide. However, the
genetic components underlying wheat drought tolerance are largely unknown. Here, we …

Whole-genome duplication (WGD) is characteristic of almost all fundamental lineages of
land plants. Unfortunately, the timings of WGD events are loosely constrained and …

The advances accelerated by next‐generation sequencing and long‐read sequencing
technologies continue to provide an impetus for plant phylogenetic study. In the past …

Deciphering the global distribution of polyploid plants is fundamental for understanding
plant evolution and ecology. Many factors have been hypothesized to affect the uneven …
