There will be a 80-minute open-call symposium (a parallel session) on

"Genome Alignments: Are We Ready to Unravel Evolution Across the Tree of Life?"

at the #MBSJ2025 (#Molecular #Biology Society of #Japan) #conference, also known as "#Bunsei", in #Yokohama on December 3rd; I am co-organiser with Martin Frith. We have a couple of slots left for 10~15 min talks with a the possibility of partial support for international speakers. We are on a mission that no gender should be over-represented, and you surely can guess which one is at the moment.

Here is the symposium abstract: #Chromosome-scale and complete #genome #assemblies are becoming available for organisms across the whole #TreeofLife. Genome #alignments empower studies that cover #evolutionary scales from thousands to billions of years. This symposium will present the latest biological insights obtained from genome alignments as well as new methods, software and pipelines.

Please contact me at my work email if you have some results that fit well and you would like to present! Here is the URL to the conference website.

Autophagy-related protein Atg11 is essential for microtubule-mediated chromosome segregation

Autophagy-related proteins have roles in several cellular processes, but their function in genome stability remains unclear. Here, the authors show that Atg11 has an essential non-canonical function in error-free chromosome segregation via the Kar9-dependent spindle positioning pathway.

How can a selfish chromosome escape genome-wide meiotic drive?

Abstract: B chromosomes are supernumerary, non-essential chromosomes that persist in populations by gaining a transmission advantage through diverse, species-specific cellular mechanisms. In this study, we investigate their behaviour in the mealybug Pseudococcus viburni, which exhibits an unusual reproductive system known as paternal genome elimination (PGE). In PGE, males selectively recognize, silence, and eliminate the paternally inherited chromosome set during meiosis, ensuring that only maternally derived chromosomes are transmitted to the offspring. Remarkably, in P. viburni, “selfish” B chromosomes have evolved a strategy to escape paternal genome elimination, allowing them to be transmitted regardless of parental origin. We hypothesized that B chromosomes avoid exclusion by modifying their chromatin state to mimic that of maternal chromosomes. Our findings reveal distinct chromatin profiles between maternal and paternal chromosomes, marked by euchromatic histone modifications on maternal chromosomes and heterochromatic modifications on paternal chromosomes. Crucially, we identified key histone modifications that coincide with chromatin remodelling of the B chromosome, facilitating its repositioning and segregation with the maternal set during meiosis.

Bacterial 'jumping genes' can target and control chromosome ends

Transposons, or "jumping genes"—DNA segments that can move from one part of the genome to another—are key to bacterial evolution and the development of antibiotic resistance.

Enhancing chromosome detection in metaphase cell images

ChromTR, a novel framework for chromosome detection in metaphase cell images, represents a significant advancement in the field of cytogenetics. This framework, which integrates semantic feature learning and chromosome class distribution learning, is designed to automate the detection and classification of 24 types of chromosomes in raw metaphase cell images.
