The first haploid angiosperm, a dwarf form of cotton with half the normal chromosome
complement, was discovered in 1920, and in the ninety years since then such plants have …

Plant speciation and diversification strongly rely on structural changes in the nuclear
genome, both at the whole ploidy and individual chromosome level. Phylogenetic …

Many previous studies have provided evidence for genome changes in polyploids, but there
are little data on the overall population dynamics of genome change and whether it causes …

Comparative genetics, genomics and cytogenetics provide tools to trace the evolutionary
history of extant genomes. Yet, the interpretation of rapidly increasing genomic data is not …

As an increasing number of plant genome sequences become available, it is clear that gene
content varies between individuals, and the challenge arises to predict the gene content of a …

Polyploidization and recombination are two important processes driving evolution through
the building and reshaping of genomes. Allopolyploids arise from hybridization and …

Polyploidy promotes the restructuring of merged genomes within initial generations of
resynthesized Brassica napus, possibly caused by homoeologous recombination at meiosis …

The glaucous appearance of wheat (Triticum aestivum) and barley (Hordeum vulgare)
plants, that is the light bluish-gray look of flag leaf, stem, and spike surfaces, results from …

Heterosis (or hybrid vigor) is a natural phenomenon whereby hybrid offspring of genetically
diverse individuals display improved physical and functional characteristics relative to their …

THE origins of meiosis in early eukaryotic history have never been satisfactorily explained.
Since the reduction-division process in meiosis is essential for sexual life cycles, discussion …
