GBE Cover of April issue 2020

Our illustration anther smut fungus infection of Silene latifolia made it for the GBE (Genome Biology and Evolution) April Cover.

In this paper, we found that
#DifferentialExpression between haploid mating types is associated with various degenenerious mutations,

My first preprint and first paper on fungi genomics, mating-type chromosomes and differential gene expression

Differential gene expression is associated with degeneration of mating-type chromosomes in the absence of sexual antagonism

A happy coincidence of my two papers are online on the same day!

What a happy coincidence today! Thrilled to see our two frog sex chromosome evolution papers are out today! 1f64c 1f64c
Good chance to know more about evolution of sex-biased gene expression in early stage of sex chromosome evolution, and a crazy fast rate of sex chromosome turnover in true frogs. Check them out!

Manuscript on plant polyploidy is submitted today

Today is a happy day overall: my manuscript on a new polyploid Mercurialis annua species inferring from functional divergence in inflorescence morphology, hybrid sterility and patterns of introgression has been submitted! The ms reads very nicely, hopefully the reviewers will like it too.

We had delicious Thai dish, Pad Thai and Phanaeng curry, to celebrate a ms submission!
