Gamete formation without meiosis in Arabidopsis
M Ravi, MPA Marimuthu, I Siddiqi - Nature, 2008 - nature.com
Apomixis, the formation of asexual seeds in plants, leads to populations that are genetically
uniform maternal clones. The transfer of apomixis to crop plants holds great promise in plant …

Epigenetically mismatched parental centromeres trigger genome elimination in hybrids
Wide crosses result in postzygotic elimination of one parental chromosome set, but the
mechanisms that result in such differential fate are poorly understood. Here, we show that …

[HTML][HTML] Meiosis-Specific Loading of the Centromere-Specific Histone CENH3 in Arabidopsis thaliana
Centromere behavior is specialized in meiosis I, so that sister chromatids of homologous
chromosomes are pulled toward the same side of the spindle (through kinetochore mono-…
