Recent studies have shown that speciation through allopolyploidy, ie, inter-specific or inter-
generic hybridization followed by chromosome doubling, is accompanied by a variety of …

Bread wheat (Triticum aestivum L.) is an allohexaploid, and the transcriptional
characteristics of the wheat embryo and endosperm during grain development remain …

Polyploidization is one of the major driving forces in plant evolution and is extremely
relevant to speciation and diversity creation. Polyploidization leads to a myriad of genetic …

Primary allopolyploids are not only ideal materials to study species evolution, but also
important bridges in incorporating genetic diversity of wild species into crops. Primary …

In the year 2018, the world witnessed the finale of the race to sequence the genome of the
world's most widely grown crop, the common wheat. Wheat has been known to bear a …

Common wheat is a hexaploid species with most of the genes present as triplicate
homoeologs. Expression divergences of homoeologs are frequently observed in wheat, as …

Bread wheat derives from a grass ancestor structured in seven protochromosomes followed
by a paleotetraploidization to reach a 12 chromosomes intermediate and a …

Bread wheat (Triticum aestivum L.) is an allopolyploid species containing three ancestral
genomes. Therefore, three homoeologous copies exist for the majority of genes in the wheat …

Alternative splicing (AS) occurs extensively in eukaryotes as an important mechanism for
regulating transcriptome complexity and proteome diversity, but variation in the AS …

Background During the bread wheat speciation by polyploidization, a series of genome
rearrangement and sequence recombination occurred. Simple sequence repeat (SSR) …
