Allopolyploidy-Induced Rapid Genome Evolution in the Wheat (Aegilops–Triticum) Group
- H. Ozkan, A. Levy, M. Feldman
- Biology, Medicine
- The Plant Cell Online
- 1 August 2001
To better understand genetic events that accompany allopolyploid formation, we studied the rate and time of elimination of eight DNA sequences in F1 hybrids and newly formed allopolyploids of… Expand
Sequence Elimination and Cytosine Methylation Are Rapid and Reproducible Responses of the Genome to Wide Hybridization and Allopolyploidy in Wheat
- H. Shaked, K. Kashkush, H. Ozkan, M. Feldman, A. Levy
- Biology, Medicine
- The Plant Cell Online
- 1 August 2001
Interspecific or intergeneric hybridization, followed by chromosome doubling, can lead to the formation of new allopolyploid species. Recent studies indicate that allopolyploid formation is… Expand
Gene loss, silencing and activation in a newly synthesized wheat allotetraploid.
- K. Kashkush, M. Feldman, A. Levy
- Biology, Medicine
- Genetics
- 1 April 2002
We analyzed the events that affect gene structure and expression in the early stages of allopolyploidy in wheat. The transcriptome response was studied by analyzing 3072 transcripts in the first… Expand
Rapid elimination of low-copy DNA sequences in polyploid wheat: a possible mechanism for differentiation of homoeologous chromosomes.
To study genome evolution in allopolyploid plants, we analyzed polyploid wheats and their diploid progenitors for the occurrence of 16 low-copy chromosome- or genome-specific sequences isolated from… Expand
Transcriptional activation of retrotransposons alters the expression of adjacent genes in wheat
- K. Kashkush, M. Feldman, A. Levy
- Biology, Medicine
- Nature Genetics
- 2003
Retrotransposons are a principal component of most eukaryotic genomes, representing roughly 40% of the human genome and 50–80% of some grass genomes. They are usually transcriptionally silent but can… Expand
A new powdery mildew resistance gene: Introgression from wild emmer into common wheat and RFLP-based mapping
- J. Rong, E. Millet, J. Manisterski, M. Feldman
- Biology
- Euphytica
- 1 September 2000
An Israeli accession (TTD140) of wild emmer, Triticum turgidum var. dicoccoides, was found resistant to several races of powdery mildew. Inoculation of the chromosome-arm substitution lines (CASLs)… Expand
Allopolyploidy – a shaping force in the evolution of wheat genomes
- M. Feldman, A. Levy
- Medicine, Biology
- Cytogenetic and Genome Research
- 1 March 2005
Recent studies have shown that allopolyploidy accelerates genome evolution in wheat in two ways: (1) allopolyploidization triggers rapid genome changes (revolutionary changes) through the… Expand
Wheat Hybridization and Polyploidization Results in Deregulation of Small RNAs
- Michal Kenan-Eichler, D. Leshkowitz, +4 authors A. Levy
- Biology, Medicine
- Genetics
- 1 June 2011
Speciation via interspecific or intergeneric hybridization and polyploidization triggers genomic responses involving genetic and epigenetic alterations. Such modifications may be induced by small… Expand
Triticum dicoccoides: An important genetic resource for increasing zinc and iron concentration in modern cultivated wheat
Abstract One major strategy to increase the level of zinc (Zn) and iron (Fe) in cereal crops, is to exploit the natural genetic variation in seed concentration of these micronutrients. Genotypic… Expand
