Persistent whole-chromosome aneuploidy is generally associated with nascent allohexaploid wheat
Allopolyploidization has been a driving force in plant evolution. Formation of common wheat (Triticum aestivum L.) represents a classic example of successful speciation via allopolyploidy.Expand

Construction and behavior of engineered minichromosomes in maize
Engineered minichromosomes were constructed in maize by modifying natural A and supernumerary B chromosomes. By using telomere-mediated chromosomal truncation, it was demonstrated that such anExpand

A phosphate starvation response regulator Ta-PHR1 is involved in phosphate signalling and increases grain yield in wheat
Background and Aims Phosphorus deficiency is a major limiting factor for crop yield worldwide. Previous studies revealed that PHR1 and it homologues play a key role in regulating the phosphateExpand

Efficient Targeted Genome Modification in Maize Using CRISPR/Cas9 System.
CRISPR (clustered regularly interspaced short palindromic repeats)/Cas9 system, which is a newly developed technology for targeted genome modification, has been successfully used in a number ofExpand

Mobilization of the active MITE transposons mPing and Pong in rice by introgression from wild rice (Zizania latifolia Griseb.).
Hybridization between different species plays an important role in plant genome evolution, as well as is a widely used approach for crop improvement. McClintock has predicted that plant wideExpand

Maize Centromere Structure and Evolution: Sequence Analysis of Centromeres 2 and 5 Reveals Dynamic Loci Shaped Primarily by Retrotransposons
We describe a comprehensive and general approach for mapping centromeres and present a detailed characterization of two maize centromeres. Centromeres are difficult to map and analyze because theyExpand

High frequency of centromere inactivation resulting in stable dicentric chromosomes of maize.
Somatic chromosome spreads from maize (Zea mays L.) plants containing B-A translocation chromosomes undergoing the chromosome type breakage-fusion-bridge cycle were examined by FISH. The size andExpand

Telomere-mediated chromosomal truncation in maize
Direct repeats of Arabidopsis telomeric sequence were constructed to test telomere-mediated chromosomal truncation in maize. Two constructs with 2.6 kb of telomeric sequence were used to transformExpand

Genomic constitution and variation in five partial amphiploids of wheat–Thinopyrum intermedium as revealed by GISH, multicolor GISH and seed storage protein analysis
Genomic in situ hybridization (GISH) and multicolor GISH (mcGISH) methodology were used to establish the cytogenetic constitution of five partial amphiploid lines obtained from wheat × ThinopyrumExpand

Rapid and Repeatable Elimination of a Parental Genome-Specific DNA Repeat (pGc1R-1a) in Newly Synthesized Wheat Allopolyploids
Recent work in the Triticum-Aegilops complex demonstrates that allopolyploidization is associated with an array of changes in low-copy coding and noncoding sequences. Nevertheless, the behavior andExpand
