WebMay 11, 2024 · Here, we show that overexpression of the ZMM protein HEI10 increases COs and reduces crossover interference but maintains sexual dimorphism; shorter axes length in female meiosis is still associated with fewer COs and stronger interference than … WebOct 12, 2024 · It is shown that overexpression of the Arabidopsis pro-crossover protein HEI10 increases crossovers but maintains some interference and sexual dimorphism, and advocates a CO patterning model via coarsening through the diffusion of HEI 10 along the synaptonemal complex. Meiotic crossovers are limited in number and are prevented …

WebApr 11, 2024 · Meiotic crossovers/chiasmata are not randomly distributed and strictly controlled. The mechanisms behind crossover (CO) patterning remain largely unknown. In Allium cepa, as in the vast majority of plants and animals, COs predominantly occur in the distal 2/3 of the chromosome arm, while in Allium fistulosum they are strictly localized in … WebYaniv Elkouby (Hebrew University of Jerusalem, Israel): Ciliary control of meiotic chromosomal pairing mechanics and germ cell morphogenesis in zebrafish and mouse .
