Polyploidization has played a prominent role in angiosperm evolution and speciation.
Alterations of gene expression resulting from the merging of two or more genomes are …

Bread wheat (Triticum aestivum L., AABBDD, 2n= 6x= 42), which accounts for most of the
cultivated wheat crop worldwide, is a typical allohexaploid with a genome derived from three …

The formation and evolution of common wheat (Triticum aestivum L., genome BBAADD)
involves allopolyploidization events at two ploidy levels. Whether the two ploidy levels …

In the past few years we have analysed alterations in genome structure and expression that
occur in wheat upon allopolyploidization. Our major findings in natural and synthetic …

The importance of hybridization and polyploidization in wheat speciation has been
recognized for close to a century (Sakamura 1918; Kihara 1919, 1924, 1954; Percival 1921; …

An interesting and possibly unique pattern of genome evolution following polyploidy can be
observed among allopolyploids of the Triticum and Aegilops genera (wheat group). Most …

Wheat (Triticum aestivum L.) is a staple food crop that provides 20% of total human calorie
consumption. Gene duplication has been considered to play an important role in evolution …

It is becoming increasingly evident that interspecific hybridization at the homoploid level or
coupled with whole-genome duplication (ie allopolyploidization) has played a major role in …

In order to understand the genomic changes during the evolution of hexaploid wheat, two
sets of synthetic hexaploid wheat from hybridization between maternal tetraploid wheat …

Background Polyploidization and introgression are major events driving plant genome
evolution and influencing crop breeding. However, the mechanisms underlying the higher …
