Journal ArticleDOI
Point mutation impairs centromeric CENH3 loading and induces haploid plants
Raheleh Karimi-Ashtiyani,Takayoshi Ishii,Markus Niessen,Nils Stein,Stefan Heckmann,Maia Gurushidze,Ali Mohammad Banaei-Moghaddam,Jörg Fuchs,Veit Schubert,Kerstin Koch,Oda Weiss,Dmitri Demidov,Klaus M. Schmidt,Jochen Kumlehn,Andreas Houben +14 more
TL;DR: It is shown that a single-point amino acid exchange in the centromere-targeting domain of CENH3 leads to reduced centRomere loading of C ENH3 in barley, sugar beet, and Arabidopsis thaliana.
Journal ArticleDOI
Haploidization via Chromosome Elimination: Means and Mechanisms.
TL;DR: CENH3, a variant of the centromere-specific histone H3, has been exploited to create an efficient method of haploid induction, and this approach is discussed in some detail.
Journal ArticleDOI
Chromosome elimination by wide hybridization between Triticeae or oat plant and pearl millet: pearl millet chromosome dynamics in hybrid embryo cells
TL;DR: The cause of the chromosome elimination of wheat–pearl millet hybrid is not malfunction of the kinetochores binding to the spindles but the malfunction ofthe sister chromatids segregation at anaphase especially of chromosome arm.
Journal ArticleDOI
Centromere location in Arabidopsis is unaltered by extreme divergence in CENH3 protein sequence.
TL;DR: This work demonstrates positional stability of a highly diverged CENH3 on independently evolved repeats, suggesting that the sequence specificity of centromeres is determined by a mechanism independent of CenH3.
Journal ArticleDOI
The differential loading of two barley CENH3 variants into distinct centromeric substructures is cell type- and development-specific
Takayoshi Ishii,Raheleh Karimi-Ashtiyani,Ali Mohammad Banaei-Moghaddam,Ali Mohammad Banaei-Moghaddam,Veit Schubert,Jörg Fuchs,Andreas Houben +6 more
TL;DR: The organization of centromeric chromatin of diploid barley encoding two CENH3 variants was analysed by super-resolution microscopy and suggested that both homologs meet the same function in metaphase cells.
