Centromeres are critical for accurate segregation of chromosomes and are often composed of megabases of tandemly arranged satellite repeats. Yet, despite their conserved function, the DNA sequence of ...

Rhynchospora tenuis undergoes obligate, genome-wide achiasmy in both male and female meiosis.

Nature Plants - Gamboa et al. identified three proteins that restrict meiotic crossovers near centromeres. This finding suggests that cohesion regulation plays a role in this suppression and...

The first division of meiosis is unique in its capacity to halve the ploidy of future gametes. To this end, one key innovation compared with mitosis i…

From an amoeba to a blue whale

Affinity purification in Arabidopsis identified all key subunits of the outer kinetochore KMN complex. Functional analyses revealed a striking conservation of its composition and organization across k...

DNA methylation loss at transposable elements (TEs) can affect neighboring genes and be epigenetically inherited in plants, yet the determinants and significance of this additional system of inheritan...

Fanconi anemia (FA) is a rare genetic condition that predisposes to progressive bone marrow failure, a specific spectrum of malignancies, including he…

Scientists are tinkering with plant genes to create crops that seed their own clones, with a host of benefits for farmers.

Female and male meiosis often differ in many aspects, such as their duration and the frequency as well as the positioning of crossovers. However, studying female meiosis is often very challenging and ...

The first division of meiosis is unique in its capacity to halve the ploidy of the future gametes. To this end, one key innovation compared to mitosis is the monopolar orientation of the pairs of sist...

Abstract. Abundance of established polyploid lineages varies across lineages, evolutionary time, and geography, suggesting both genetics and environment pl

Sex chromosomes are involved in three major empirical patterns: (i) Y (or W) chromosomes are often nonrecombining and degenerate; (ii) heterogametic offspring (XY or ZW) from interspecific crosses are...

Meiotic crossover formation is critical for generating viable gametes and enhancing genetic diversity. The helicase Mer3 (HFM1 in humans) is a highly conserved factor essential for promoting crossover...

Dipping fries into ketchup just got a little more mind-bending.

Insights into the dogrose genome and centromeres explain their ability to achieve stable sexual reproduction.

Prof. Dr. Miltos Tsiantis, Director at the Max Planck Institute for Plant Breeding Research and head of the Department of Comparative Development and Genetics, receives an Advanced Grant from the European Research Council (ERC). The prestigious funding will support his project CLONAL, aimed at advancing our understanding of clonal reproduction by root sucker formation.
