A complete reference genome for species with chromosomally-determined separate sexes should contain scaffolds for all sex chromosome homologs. However, sex chromosomes present distinct computational c...

In weekly roundup #38-2026 I also talk about what thigmotropism is and this week’s scientific articles and plant science in the media

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

In this review, we discuss three meiotic checkpoints—the DNA damage response, the pachytene checkpoint, and the spindle checkpoint—and highlight their similarities and differences across diverse syste...

The diversity of cultivated bananas remains partially unknown, whereas cultivars with suitable adaptive traits could address the drastically increasing biotic and abiotic constraints on banana product...

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 ...

Abstract. Recombination diversifies offspring genomes and helps ensure chromosome segregation during meiosis. Mutation rates are elevated near crossovers d

Adaptation in protein-coding sequences can be detected from multiple sequence alignments across species or alternatively by leveraging polymorphism...

Over the last year, our lab has been developing a policy on AI use. To do this, we did three main things: We read a lot of academic publications and tech news. We set up an #ai channel on our la...

Hybridization between species can contribute to parallel adaptive events. However, the prevalence of introgression is rarely measured across multip...

Saturation mutagenesis of the FCY1 promoter in budding yeast shows that adaptation to 5-fluorocytosine is not accessible through single cis-regulatory mutations, despite large mutational effects on pr...

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...

Dosage compensation and meiotic sex chromosome inactivation (MSCI) are key mechanisms regulating gene expression from the X chromosome in male-hete...

Author summary Many plants avoid self-fertilization through a system of self-incompatibility, which allows them to recognize and reject their own pollen. In plants like those in the Arabidopsis family...

Abstract. Karyotype evolution, including changes in chromosome number and structure, is a fundamental process that can influence genome organization and sp

Mosses of Europe is the most comprehensive reference work on European mosses. This 3 volume set covers identification, taxonomy and detailed descriptions, supported by high quality photographs.

Move comes after Roger Innes complained about the government’s prosecution of Chinese postdocs

Live-cell imaging reveals characteristic cytological stages of female meiosis in Arabidopsis and allows an assessment of their durations.
