ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis
Journal of Integrative Plant Biology, EarlyView.The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.

Journal of Phycology, EarlyView.Abstract The relative rates of sexual versus clonal reproduction partition genetic diversity, but the quantification of these rates remains limited in natural populations. This knowledge gap is particularly acute among tropical macroalgae. Chondria tumulosa is a red macroalga that has been documented at high abundance in the three northernmost atolls ...

Genetic Susceptibility to Periodontitis
Journal of Periodontal Research, EarlyView.Aim: The aim of this narrative review was to identify genes carrying risk alleles associated with an increased risk of periodontitis and to place them in a biological context. Methods: The literature was reviewed based on predefined criteria. Results: The identified genes largely fall into functions linking immune response with tissue repair. The genes

The incredible vulnerability that reproduction poses for plant species in a warming world
New Phytologist, EarlyView.Generalized plant responses to heat stress across whole‐plant and reproductive scales. Summary Temperatures are rising globally and threatening the persistence of natural plant populations. Elevated temperatures disrupt gametogenesis, fertilization, and seed filling, often at lower thresholds than those affecting photosynthesis, growth, or survival ...

The richness, frequency and relatedness components of mate diversity and mate portfolios
New Phytologist, EarlyView.The effects of (a) equal and (b, c) unequal contributions to mate portfolios by 10 mates on (d) Hill‐number mate diversity profiles (see Eqn 1). Summary Sexual reproduction produces genetically diverse families, especially when individuals mate with multiple partners.

New Phytologist, EarlyView.Genetic differentiation among the study species. Summary Hybridisation and whole‐genome duplication (WGD) are widespread in plants, yet their ecological consequences remain challenging to predict. In allopolyploids, where both processes coincide, ecological divergence is typically evaluated against a null hypothesis of ecological additivity.

Divergent trajectories of genome architecture and chromosome evolution in ferns and angiosperms
New Phytologist, EarlyView.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 ...

New Phytologist, EarlyView.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.
