I am pleased to share our work on Cavendish bananas, a clonally propagated crop. Using somatic mutations from >100 bananas collected worldwide, we reconstructed their global dissemination history and genetic microevolution under large-scale cultivation. researchsquare.com/article/r…

Somatic mutations trace the global spread and microevolution of Cavendish bananas

Bananas (Musa spp.) are among the earliest domesticated fruit crops, with a cultivation history spanning nearly 10,000 years. Among the hundreds of banana cultivars, the clonally propagated triploid...

We posted a preprint, "Clonal dynamics of monozygotic twinning in early human embryogenesis" biorxiv.org/content/10.1101/…. This study revealed 3 types of identical twins ( para-, sub-, and full-identical), according to cellular lineage dynamics prior to embryonic splitting. @cjyoon__

Clonal dynamics of monozygotic twinning in early human embryogenesis

Monozygotic twins are derived from the split of a single zygote early in embryogenesis. Although it was hypothesized that the timing of twining is overall associated with fetal membrane configuration...

Our work, published in Genome Research this week (pubmed.ncbi.nlm.nih.gov/4085…), reports that APOBEC3A, not APOBEC3B, is the dominant DNA mutator in human normal cells, surprisingly. Many thanks @HFSP for support, and all authors, particularly Yohan, Ji-Hyun, Joonoh and BK!

APOBEC3A drives deaminase mutagenesis in human gastric epithelium - PubMed

Cancer genomes frequently carry apolipoprotein B mRNA editing catalytic polypeptide-like (APOBEC)-associated DNA mutations, suggesting APOBEC enzymes as innate mutagens during cancer initiation and...

Today I got to meet a hero of mine, Prof Eunjoon Kim (left) from @kaistpr and @IBS_media. I was lucky to mentor his former PhD student @changukchung (middle) who recently joined KAIST as a Prof. What a day!
