Divergent trajectories of genome architecture and chromosome evolution in ferns and angiosperms
New Phytologist, Volume 252, Issue 1, Page 427-442, October 2026.Variation in key fern genomic traits across families, mapped onto a summary phylogenetic tree. Summary Ferns and angiosperms represent the two largest vascular plant lineages but exhibit striking genomic and ecological contrasts. We investigated whether differences in genome size, chromosome architecture, GC content, and stomatal traits reveal ...

Regulation of Meiotic Recombination [PDF]
, 2011 Meiotic recombination results in the heritable rearrangement of DNA, primarily through reciprocal exchange between homologous chromosome or gene conversion. In plants these events are critical for ensuring proper chromosome segregation, facilitating DNA repair and providing a basis for genetic diversity.

New Phytologist, Volume 252, Issue 1, Page 145-162, October 2026.Long‐read whole‐genome sequencing revealed extensive chromosomal rearrangements and aneuploidy in a widely used Chlamydomonas reinhardtii stt7‐1 mutant. The STT7 gene (shown in red) was found to be split between two rearranged chromosomes, providing a molecular explanation for the long‐standing failure of this mutant in genetic crosses.

Annals of the New York Academy of Sciences, Volume 1564, Issue 1, October 2026.Epitranscriptomic marks are highly variable across life stages and tissues, complicating comparisons between species. Using m6A consensus motifs, we developed a genomic indicator reflecting transcript methylability, the DRACH o/e score, that we used to investigate epitranscriptomic features and associated functions across nine bilaterian species.

A molecular cytogenetic study of intergenomic recombination and introgression of chromosomal segments in lilies (Lilium) [PDF]
, 2009 Lilies (Lilium L.) are one of the most important ornamental bulbous crops for cut flower industry grown extensively in The Netherlands for last few decades. The genus Lilium consists of seven different sections with about 80 species. The species within

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.ABSTRACT In vitro embryo production is a key tool in reproductive biotechnology, enabling genetic improvement, basic research on early development, and the generation of biomedical models. Despite high rates of nuclear maturation achieved during in vitro maturation (IVM) of porcine oocytes, inadequate cytoplasmic maturation continues to limit oocyte ...

Meiotic double-strand break repair DNA synthesis tracts in Arabidopsis thaliana.
PLoS GeneticsWe report here the successful labelling of meiotic prophase I DNA synthesis in the flowering plant, Arabidopsis thaliana. Incorporation of the thymidine analogue, EdU, enables visualisation of the footprints of recombinational repair of programmed ...
