Polyploidy is a major evolutionary process in eukaryotes—particularly in plants and, to a
less extent, in animals, wherein several past and recent whole-genome duplication events …

Polyploidy, or the presence of two or more diploid parental genome sets within an organism,
is found to an amazing degree in higher plants. In addition, many plant species traditionally …

Investigators have long searched for a polyploidy paradigm—rules or principles that might
be common following polyploidization (whole‐genome duplication, WGD). Here we attempt …

Abrupt speciation through interspecific hybridisation is an important mechanism in
angiosperm evolution. Flowering plants therefore offer excellent opportunities for studying …

Crocus sativus is a triploid sterile plant characterized by its long red stigmas, which produce
and store significant quantities of the apocarotenoids crocetin and crocin, formed from the …

Publisher Summary This chapter provides a discussion of recent advancements, in context
to plant polyploidy. Polyploidy plays a very important role in plant evolution. Major recent …

Reptiles are the only truly parthenogenetic vertebrates, making it especially fascinating to
understand how and why some reptilian taxa have broken free of sexual reproduction. In this …

Interspecific hybridization is an important mechanism of speciation in higher plants. In
flowering plants, hybrid speciation is usually associated with polyploidy (allopolyploidy), but …

Hybridization and polyploidization are now recognized as major phenomena in the
evolution of plants, promoting genetic diversity, adaptive radiation and speciation. Modern …

The authors analyze the archeological, historical, botanical, cytological, geographic,
molecular and reproductive biology of saffron and allied species in order to establish its site …
